Summary of the work of sanitation managers

Summary is a written material to evaluate and describe the achievements, existing problems and lessons, which can make us think, so it is very necessary to write a summary. But I found that I didn't know what to write. The following is my summary of the work of sanitation administrators. Welcome to reading. I hope you will like it.

Summary of the work of sanitation managers 1 20xx, our hospital will seriously organize and implement all the work according to the goal of "creating a sanitary city" and promote the work from the following aspects:

1, the construction of domestic waste landfill is the focus of our work in 20xx. Our hospital will organize and cooperate with relevant departments to build the domestic waste landfill project, and will strictly control the quality, ensure the quality is qualified, and strive for the follow-up construction funds in place.

Summary of Year-end Personal Work of 20xx Sanitation Workers

Health work has been further developed this year, and one year will soon pass. Looking back on this year's work, although great progress has been made, there are still many places to be improved. Now I will summarize my personal work as follows:

First, do a good job and improve the health quality of the city. Urban sanitation work can not be separated from the real work of every sanitation worker. If we have more enthusiasm for sanitation and complete sanitation work more seriously, it will be directly reflected in the cleanliness of roads, so we must take our work seriously. As a beautician in the city, I must prove this honorary title with practical actions. During this year, I worked hard in my post in line with my responsibility for sanitation, which reflected my love for sanitation.

Second, strengthen environmental cleanliness and effectively dispose of garbage. In addition to strengthening the cleanliness of roads, we also need to deal with garbage more effectively. The collection and removal of garbage is done in strict accordance with the instructions of our superiors. At the same time, we brought the collective wisdom of sanitation workers into play, effectively recycled garbage and created a certain economic income. For this part of wisdom wealth, we use it to improve sanitation tools and make our work more efficient. In addition to road cleaning, we also carried out detailed management and set up sanitation supervision posts according to the prosperity of road sections, the flow of people and vehicles and the configuration of sanitation facilities.

Third, it is not enough for the city's ambient light to rely on the work of our sanitation workers, and the beautiful environment depends on the participation of citizens. Although our work has been done in place, there are still many citizens whose health awareness has not been improved, and littering often happens. Therefore, it is necessary for the relevant departments to increase publicity, raise public awareness of city appearance and sanitation, let the public participate in environmental sanitation protection, and carry out comprehensive environmental sanitation improvement activities in a solid manner. If it doesn't work, then relevant punishment regulations are needed to force the public to raise health awareness when necessary.

Fourth, as a sanitation worker, although our treatment has been improved, I hope the relevant departments can pay more attention to the living conditions of our sanitation workers in view of the danger of our working environment and the unfair wages. Although the sanitation work itself is of great significance, the treatment and social status of our sanitation workers have never been properly reflected. As sanitation workers, we still hope to get due treatment and improve our living conditions.

Over the past year, sanitation work is developing in a good direction, and urban sanitation has improved significantly. As a sanitation worker, I will, as always, adhere to the cause of urban sanitation and provide a better living environment for the citizens.

Summary of the work of sanitation managers. It is the sacred mission of every sanitation worker to beautify the city appearance, community streets and give people a comfortable living and working environment, and it is also our duty to follow in our daily work. In order to respond to the call of the municipal government, to make our beautiful city more beautiful, and to improve the quality of life of every citizen in our green capital, I did the following work in 20xx:

First, love your job and be diligent.

With the deepening of the market economy, social employment has been far from being limited to the "72 line" and there is no such distinction as "369". In particular, our sanitation work has long been recognized as a "sacred" profession by the world, and people have given us a noble and elegant name-urban beautician. As sanitation workers, we are proud and deeply responsible.

To this end, we should base ourselves on our posts, respect our posts, love the industry, take pride in our work, cherish this industry in our hearts, let us turn our true love into infinite strength, make unremitting efforts in this fertile soil of sanitation, and wash away the muddy water in the streets with our hard sweat; With our hard-working hands, describe the corner of the roadway in urban communities!

Second, start from me and make enthusiastic dedication.

As we all know, sanitation work is very hard and needs sweat, strength and love. When others are still asleep and enjoying the warmth of family and family happiness, in winter, we quietly climb out of the hot bed, walk out of the warm home and set foot on the cold street. Under the sleepy eyes of street lamps, in the biting cold wind, we cleaned up the ice and snow on the road, a shovel, a pickaxe and flying arms, knowing that we were bitter and self-aware. Although the wind is cold, we are all sweating. In summer, under the scorching sun, stick to your post in the wind and rain. Others can walk leisurely in the street with umbrellas and beautiful miniskirts. We can only wear work clothes, endure the heat, sweep the dirt on the road with a broom, and take the cleaned garbage away with a shovel.

In the spring breeze, in the autumn rain, the figure of our sanitation workers always moves on the street. For the clean environment and the happiness of others' lives, we silently offer our sincerity and love. When the sun is shining, people walk in clean streets, talking and laughing, and our hearts are sweet, just like drinking ice water in June. People's smiling faces are the highest praise for our sanitation workers!

Third, exchange our true feelings for a better tomorrow.

Let people live and work in a clean environment is the goal of our sanitation workers. When people drink a cup of soybean milk in the morning and pick up their briefcases to go to work, clean streets will make you feel comfortable and make you interested, motivated and eager for a day's work; When people finish their day's work at night and walk in the clean streets with their families after dinner, your heart will naturally look brand-new. This kind of mood will make you relax the fatigue of the day, and start to enjoy the warmth of your family happily and feel the happiness of your family. Don't let the dirty, chaotic and poor environment affect people's normal life and work. No matter how hard and tired we sanitation workers are, it is worth it. This is everyone's idea here.

At the same time, we are all working hard for this goal in our own posts. Today, with the high development of material civilization and spiritual civilization, the status of our sanitation workers is gradually rising, and people are increasingly recognizing our work. We have thousands of reasons to believe that with our true feelings, we will definitely get a better tomorrow!

I will continue to take "beautifying the environment and improving the quality of life and work of citizens" as my responsibility, and work silently and selflessly in the ordinary and sacred sanitation post to create comfortable living and working space for citizens and bring people a clean, environmentally friendly and healthy tomorrow!

Summary of the work of sanitation managers. I worked as an intern in the X sanitation bureau. After one year's practical study, the specific internship experience and work situation are summarized and reported as follows.

First of all, I strengthened my practical study during my internship in X Environmental Sanitation College. On the first day of work, Director X introduced me to the work area (all sections south of xx Road, west of X Road and east of X Road) and the daily work in my area (street cleaning, management of mobile vendors, spreading illegal advertisements on roads, etc. ) and gave guidance on the specific work and the difficulties and key points of the work. For example, the daily work in our jurisdiction includes: street cleaning, the management and removal of mobile vendors and illegal advertisements, the management of the three-package area in front of the door, the occupation of roads and the collection of clearing fees. In my jurisdiction, the key work is the cleaning of main streets and sidewalks and the distribution of vehicles around the city. During my work, my colleagues and I completed the management and supervision of the jurisdiction and combined theoretical knowledge with practice.

Secondly, under the careful instruction of Director X, combined with the specific situation of our jurisdiction (involving many roads and lanes and different sections), combined with the actual situation of our jurisdiction, we classified our work priorities according to different sections. For example:

(1) On roads with large passenger flow such as xx, we should focus on road cleaning and management of mobile vendors, especially on Qingnian Road, and always check the removal of illegal advertisements and the sanitation of the three bags in front of the door.

(2) In the X road and other sections, focus on checking the situation of mud thrown by freight vehicles and roads.

(3) Other road sections are mainly based on road cleaning and cleaning, and are inspected regularly. In addition, due to the existence of X field, there are many scattered booths in the surrounding sections (Qingnian Road, etc.). ), but human resources are limited. We make full use of human resources, rationally adjust personnel allocation, and take the following measures in combination with the actual situation in our jurisdiction:

(1) We have strengthened the cleaning and cleaning of the roads around the X market, and at the same time strengthened the management of the surrounding vendors.

(2) For the road sections with more freight vehicles and serious dispersion, strengthen inspections, increase the number of inspections, and strictly demand standardized transportation of vehicles.

(3) For some streets and lanes with less traffic and people flow, cleaning is the main method, and irregular cleaning and patrol inspection are adopted. If the sanitary conditions are found to be unqualified, they will be dealt with immediately. The above work is formulated according to the special situation of our jurisdiction. Under this premise, the daily work of our district is carried out normally.

Finally, through the short internship in X Environmental Sanitation Institute, I have a deeper understanding of the general situation of the work of the environmental sanitation department, a broader understanding of the nature of the work of my environmental sanitation personnel, and also learned more practical experience during my work. And in the future work, we should learn from our work experience and correct our past shortcomings. Let the sanitation work in our district flourish, and let the citizens in our district have a better working and living environment.

Summary of the work of sanitation management personnel In June and September, our department further strengthened the evaluation work, earnestly grasped the garbage removal work and the management of public toilets and garbage stations, and made great efforts to supervise the cleaning of secondary roads and small streets, so that the environmental sanitation work in the whole region was balanced. This month's work is briefly summarized as follows:

First, strengthen the assessment and promote the improvement of environmental sanitation quality in the whole region.

In order to comprehensively improve the quality of road environmental sanitation in the whole region, our department has further strengthened the evaluation work. The first is to strengthen the evaluation of general scanning of main roads. Every morning at 7:00-8:00, the evaluation office conducts irregular spot checks on the quality of cleaning. If it is found that the general cleaning fails to meet the requirements, the cleaning company will be fined according to the scoring standard and deduction principle. Due to the general cleaning in place, the overall level of cleaning and cleaning of main roads has improved.

The second is to strengthen the application of evaluation results. In view of the lack of posts, inaction and unsatisfactory operation results of the main road cleaning staff, the sanitation department intensified the evaluation, deducted points and deducted money in strict accordance with the evaluation criteria, and asked the company to investigate the responsibility according to the evaluation results, and punished the salesman, monitor and cleaning staff according to the standards of 5%, 20% and 50% respectively. At the same time, the district environmental sanitation department will return the deducted money to the cleaning and cleaning company in full, requiring the company to reward employees with outstanding work performance according to the assessment results of departments and companies, so as to realize the goals of rewarding diligence and punishing laziness, rewarding the excellent and punishing the poor. By improving the assessment system and implementing rewards and punishments, employees' sense of responsibility has been further enhanced and their work enthusiasm has been greatly mobilized.

The third is to strengthen the environmental sanitation supervision of secondary roads and small streets. The evaluation office conducts daily inspections on small streets and lanes such as Hetai Road, Wenhua Road, Donghu Road, Songshi Road, Yuetang South Road, Xinhe East Road, Xinhe West Road, Guihua Road, Zhongnan Market Road, Daping Road and Qiyang Road, and records in detail the on-the-job situation of cleaning and cleaning personnel and the health status of road sections. During the evaluation process, the district environmental sanitation department will clean up the outstanding problems existing in the cleaning work and feedback them to the street office in time.

The department and the cleaning company under its jurisdiction require timely rectification. After the evaluation, the district environmental sanitation department will sort out the daily evaluation records and issue a special report, so as to scientifically judge the cleaning and cleaning work of secondary roads and small streets.

Two, strengthen management, to ensure that the management of public toilets and garbage stations in place.

In order to improve the management level of public toilets and garbage stations, our department has further strengthened the management of public toilets and garbage stations. The first is to strengthen the education of the personnel on duty. Our office organizes the personnel on duty to hold a business analysis meeting once a month to learn the rules and regulations of the unit, the operating specifications of the equipment and the business knowledge of the management of public toilets and garbage stations, so as to continuously improve the overall quality of the personnel on duty. The second is to increase the inspection of public toilets and garbage stations. The department requires the staff of the management department of public toilets and garbage stations to inspect all public toilets and garbage stations more than twice a week, point out the problems existing in the work, put forward rectification opinions, find problems in time and solve them in time. The third is to increase the evaluation. The evaluation office will increase the number of evaluations of public toilets and garbage stations, focusing on those with more problems. The assessment results are linked to performance pay. By strengthening management, the work responsibility and initiative of duty personnel are enhanced, and the management level of public toilets and garbage stations is effectively improved. Fourth, strengthen the maintenance of equipment and facilities. The sanitation department regularly sends special personnel to guide the personnel on duty in public toilets and garbage stations to inspect and maintain the equipment and facilities, which effectively prolongs the service life of the equipment and reduces the maintenance cost of the facilities.

Third, optimize services and improve the efficiency of garbage removal.

In order to ensure the timely removal of garbage, the sanitation department has strengthened its internal management and continuously improved its working methods. The first is to strengthen service awareness. My office requires the pickup company to establish a sense of quality service, strengthen contact with the personnel on duty at various garbage sites, keep abreast of the garbage collection situation at each site, arrange drivers and vehicles in advance, and make reasonable and scientific arrangements. The second is to strengthen education and improve the quality of employees. The motorcade organizes drivers and maintenance personnel to conduct business training every week to learn vehicle maintenance knowledge and strengthen safety awareness. The third is to strengthen vehicle maintenance. Based on the principle of "pay more attention to maintenance, less maintenance", the automobile team carries out daily inspection and inspection on vehicles in time, and carries out maintenance on vehicles on time. By strengthening the maintenance of vehicles, we can effectively reduce the "big problems" of vehicles, improve the rate of vehicles leaving and improve the efficiency of garbage removal.
