Environmental Monitoring Station Internship Summary 1

No relevant work experience may be an inherent disadvantage for most graduate students in employment. Off-campus professional practice for graduate students can accumulate work experience and help us gain comparative advantages. In the recruitment process, social practice experience and experience are definitely more convincing than traditional professional internships and participation in projects.

In addition, it can increase employment opportunities. On the one hand, the practice unit is the employer, and the practice process is the trial process;

On the other hand, graduate students can collect employment information or directly Contact the employer.

Off-campus social practice for graduate students is an excellent opportunity to practice communication skills, learn to live in harmony with others, and communicate effectively. After reporting to the practice unit, you must actively adapt to the learning and living environment, integrate into the unit group, learn with an open mind, and live in harmony; good social and psychological qualities and interpersonal communication skills are not innate and can only be acquired through personal socialization. Learn and experience in the process. In addition, through your own personal experience, combined with the struggle experiences and successful cases of people from different walks of life in practice, you can also accurately position your social role and help you make staged career plans and long-term person plans.

Environmental monitoring is the "eyes and ears" of environmental protection. The monitoring data obtained through testing is the basic data for describing and evaluating environmental quality, and is also the basis for environmental law enforcement, supervision, decision-making, management, and services. From the acquisition and recording of raw data to calculation and organization, the team spirit and serious and careful work attitude of the environmental monitoring station are worth learning from. As a graduate student, you must be down-to-earth, diligent in observation, good at learning, and constantly improve your ability to keenly capture effective information from daily experimental data and your ability to analyze and solve problems, so as to avoid the negative impact of even a small link in scientific research experiments on the final objective "product" may.

Environmental monitoring technology is developed on the basis of environmental analysis and other disciplines. In recent years, the country has promoted cleaner production in order to effectively control pollution from the source. If environmental monitoring stations want to track and monitor the environmental pollution of enterprises in a timely manner, familiarity with the enterprise's production process can help them better understand the production links that emit pollutants. , and to monitor the emission of pollutants.

The intersection of disciplines promotes the update and progress of monitoring technology, and the innovation and upgrading of production processes and equipment. Now in our experimental research, the interactive use of cross-disciplinary technologies may be able to reduce experimental costs and quickly and efficiently make ideas suddenly clear and solve difficult problems. The rapid development of social economy has brought about environmental risk issues, and new changes have appeared in the types and structures of environmental pollutants, especially complex toxic and harmful organic pollutants. Whether they are monitored scientifically, timely and accurately is related to the life safety of the people. The monitoring and analysis methods of the environmental pollutants involved should also be enriched and improved. Due to the limited monitoring and scientific research capabilities of the third-level monitoring stations, the social practice of graduate students provides us with a fulcrum for cooperation, and at the same time sets up scientific research exchanges between us. As a bridge, we can take advantage of the technical instruments and equipment of scientific research institutes in colleges and universities to strengthen cooperation with environmental monitoring stations in related disciplines, answer the technical and other problems encountered in their actual monitoring and scientific research work, and continue to cooperate in research, Improve, perfect, and publish these good methods and good experiences in relevant journals, benefit from exchanges with the vast number of front-line monitoring scientific research technicians and related researchers, and continuously promote the advancement, standardization, and standardization of monitoring and analysis methods. normative.

(4) Sewage treatment station in Yichang factory of Shuanghui Group

Internship time: morning of June 22, 20xx

1. Overview:

Shuanghui Group is a well-known enterprise in my country and one of the top 500 in the country. However, there is an undeniable fact that it is also a large polluter. Therefore, my country also has strict regulations on its sewage discharge. This time we visited a sewage treatment station inside its Yichang factory. Although the Yichang factory is not large, its entire production process contains production wastewater, so it is also a key management unit in Yichang. Therefore, in XX, the Yichang Municipal Government ordered the factory to build this sewage treatment station with a total investment of 7-8 million yuan. It was established by Station Director Lin with a daily processing capacity of 2,200 tons. After treatment, the cod content of the wastewater reaches the national discharge standard, less than 100mg/l, and the treatment efficiency reaches 97%-98%.

2. Treatment process:

The activated sludge process, also called biochemical treatment, is anaerobic and oxygen-consuming. The activated sludge process is the most widely used aerobic biochemical treatment technology for wastewater.

3. Treatment process flow:

Wastewater with high concentration first enters from the mountain pool. The so-called mountain pool is a mesh. Larger wood blocks in the wastewater are first removed; then it reaches the primary sedimentation tank; Three steps to the regulating pool. Its function is that when the water is high, it is impossible to enter from the front and can only stay inside. When the water is low, it exists in it first, and when the water is high, it can be returned after entering. One is the function of pre-acidification, which makes the pH value of the wastewater above a certain value; then the wastewater is lifted to the flotation tank through a pump. Its function is to aerate the wastewater so that it can fully consume oxygen. In this tank, there are also Add high-efficiency disinfectant and degradant polyaluminum chloride to remove oil, heavy metals and some salts; the fifth step is to go to the anaerobic tank, the purpose is to remove all oxygen in the wastewater, because some microorganisms can survive in the absence of oxygen. Under certain circumstances, other microorganisms can be consumed. The anaerobic tank uses this principle to treat other microorganisms in the wastewater. The sixth step is to enter the oxygen consumption tank, which is the aeration tank, in order to fully oxygenate the wastewater and activate the wastewater. The sludge is fully digested and reproduced inside; in the seventh step, it enters the secondary sedimentation tank to separate activated sludge and wastewater. The sludge in the secondary sedimentation tank is returned to the aeration tank for reuse; and finally it enters the disinfection tank. pool and then drain.

(5) Yichang City No. 4 Water Plant

Internship time: the morning of June 23, 20xx

1.

Overview

The plant was established in the 1970s and completed in the mid-1980s. It uses the tap water production technology of the 1980s, which is a relatively advanced automated technology. There are four water plants in Yichang City. The first water plant is used by Three Gorges University. It is on the mountain next to the TV Tower. It was established before liberation, but the technology is relatively outdated. The Second Water Plant was built on Yangcha Road in the 1960s. Later, due to the development of Yichang City, the third and fourth water plants were built successively.

2. Process:

Water is extracted from Guanzhuang Reservoir, piped to the first-level pump room (water intake pump room), and chlorine is added in front of the first-level pump room to kill algae, plants and shellfish. The water is then sent to the plant treatment system through the primary pump room. Usually after mixing (adding an appropriate amount of aluminum chloride, commonly known as alum) to the source water, reaction, precipitation, filtration, disinfection and other treatment processes, each process is equipped with corresponding structures (such as sedimentation tanks, filters, clean water pools, etc.), and the filter Post-disinfection generally involves adding chlorine and ammonia. The water with the disinfectant added passes through the clear pool and stays in the pool for about an hour before it becomes qualified drinking water. It is then pressurized and transported to the city through the secondary pump room (water transfer pump room). In the pipe network, it is used for domestic drinking and production.

(6) Yihua Chemical Industry

Internship time: the morning of June 24, 20xx

1. Overview:

This factory is the last stop for our internship, and it is also an important stop, because the treatment of waste gas is also an important part of our environmental engineering major. The exhaust gas treatment device in the factory is quite advanced, with a dust removal rate of up to 95%.

2. Process:

Desulfurization and dust removal. First, electrostatic precipitator is used. Electrostatic precipitator is a method that uses electrostatic force to separate suspended particles from the air flow, and the energy consumption for separating dust particles is low. Generally, the power consumption for processing 1000m 3 /h of dust-containing gas is only 0.1 —0.8kw. h, the air pressure loss is also very small. Because the relatively large electrostatic force acts on the particles, even extremely small particles can be effectively captured, so the dust removal effect is very good, with a dust removal rate of more than 95%.

Three. Internship experience:

After passing this internship, I have a preliminary understanding of environmental engineering and am full of hope for my employment prospects. Because human survival depends on the environment, and the important task of protecting the environment is about to fall on our shoulders, we must study professional knowledge seriously and master the professional knowledge we have learned, hone ourselves in practice, and make the professional knowledge we have learned You can integrate knowledge, know how to apply what you have learned, and become a qualified environmental worker and a qualified environmental engineer! ;
