The turbidity of water is 50 times as high as usual.

"Why did Qiqihar stop water?" "On such a hot day, I didn't drink all night and couldn't take a bath. It's too uncomfortable. " The reporter learned from the Qiqihar Housing and Urban-Rural Development Bureau that due to the flood in the upper reaches of Nenjiang River, the turbidity of Nenjiang River increased sharply on the 20th 15, which is rare in history. The production capacity of Liuyuan Waterworks, which takes Nenjiang water as its water source, is affected, which also affects the water consumption of most users who use tap water in Qiqihar.

Nenjiang River originated in Inner Mongolia Autonomous Region, and its main stream merged with the south source of Songhua River in Zhaoyuan County to form Songhua River. On June 5438+08, Xinfa Reservoir and Yong 'an Reservoir in Molidawa Daur Autonomous Banner, Hulunbeier City, Inner Mongolia, were dam-broken due to heavy rain. The flood discharged from the reservoir, wrapped in sediment, flows into the main stream of Nenjiang River, causing the turbidity of water in Qiqihar section of Nenjiang River to rise sharply.

The inspector examined the water sample.

According to the inspection of Qiqihar Water Department, the turbidity of Nenjiang River reached 4000 degrees on 20th 15, and nearly 5000 degrees on 2nd16: 00. The normal turbidity of Nenjiang River is within 100 degree, which is 50 times of the usual turbidity. The water is turbid, which is rare in history.

The water source of Liuyuan Waterworks, the main water supply plant in Qiqihar City, comes from Nenjiang River. Due to the serious impact of high turbidity Nenjiang water on the operation of Liuyuan Waterworks, in order to ensure the safety of drinking water quality, the water supply of Liuyuan Waterworks was reduced from the original' 6,500 tons/hour' to 1.500 tons/hour from 6: 00 on June 2.

Nierji diluted the river with water.

Start the standby water source

The reporter learned from the Propaganda Department of Qiqihar Municipal Committee that Liuyuan Waterworks is the largest water source in Qiqihar, and the reduction operation will inevitably affect the water supply of residents. The northern third district is the most affected. In addition to issuing reminders and announcements to the public at the first time, they also coordinated the upstream Nierji Reservoir to increase the discharge and reduce the turbidity of the river as soon as possible.

On 19, Nierji began to discharge at 1800 m3/s, and increased the flow from 1800 m3/s to 2500 m3/s in the early morning of 22nd, which accelerated the flow speed of Nenjiang River.

Emergency use of standby water sources to ensure the basic water use of most residents in the south of Longsha District and Tiedong District. At the same time, water supply experts were invited to study the operation scheme of Liuyuan Waterworks, so as to quickly degrade the high-turbidity influent and ensure more residents to use water as much as possible, and the frequency of inlet and outlet water quality testing was adjusted from 2 hours to 1 hour, which fully met the water quality testing standards.

Qiqihar started the emergency plan for water supply. Since 2 1, the Housing and Construction Bureau of Qiqihar City has organized the Water Group to supply water at 20: 20-22: 00 on 2 1 and at 5: 00-7: 50 on 22/22, respectively, so that the waterless community of 130 can be guaranteed by stages. At the same time, strengthen the inspection and monitoring of the operation of the secondary water supply pump station, and start the water supply of the pump station in time according to the operation of the water plant.

The price of drinking water in Shang Chao does not increase.

On the 22nd, in front of a residential building, residents were waiting in line to receive water by water truck. The reporter learned that in some areas of Qiqihar, water trucks are used to supply water to residents.

Residents lined up in front of the water truck to get water.

Qiqihar Urban Management Bureau and Municipal Fire Brigade sent more than 60 sanitation sprinklers and fire engines to supply water to key water-deficient communities for cleaning toilets and other non-drinking water. City Urban Management Bureau organizes property companies to post notices in the community to increase residents' channels of knowing.

Despite the local announcement, there are still a large number of citizens buying tap water in supermarkets. The reporter learned from Yonghui Supermarket, Jiahua and other large supermarkets that they all increased the supply of goods and the supply of drinking water was sufficient. Qiqihar Municipal Bureau of Commerce made every effort to organize the distribution of commercial water to major supermarkets to meet residents' demand for water, and simultaneously cleaned up and standardized commercial outlets and supermarkets to drive up drinking water prices. At present, bottled water is being transported from Ang Ang Creek, Kedong, Keshan, Baiquan, Nehe, Gannan and other places to the North Third District in large quantities. Municipal Water Group is organizing secondary pumping stations on the first floor of Shang Chao and key water-deficient communities to access temporary water supply pipelines for residents to drink temporarily.

Achieve safe and sustainable water supply within 3 days.

Next, according to the current water quality changes in Nenjiang River and the operation and commissioning of the water plant, it is estimated that the third stage of water supply will start on 22nd16th, with a planned duration of 2 hours. Sanitation sprinklers and fire engines will randomly dispatch water to ensure the needs of residents for flushing toilets and cleaning. Please pay close attention to the information released by the government, news media, official WeChat account, water supply enterprises, community neighborhood committees and residential properties, and save water in time to tide over the difficulties.

At present, the water turbidity of Nenjiang River has dropped from 5000 degrees to more than 2700 degrees. According to the current downward trend of water turbidity in Nenjiang River, Nierji Reservoir continues to discharge, and the next flood peak will come, and the water supply will continue to improve. Starting from the 23rd, we will maintain staged water supply twice a day, fully organize the commissioning and operation of Liuyuan Waterworks, and strive to achieve safe and sustainable water supply within three days.

Background: The urban water supply in Qiqihar is composed of Nenjiang surface water from Liuyuan Waterworks and groundwater from Tiefeng, Jianhua and Longsha Waterworks. 20 18, Liuyuan Waterworks was expanded, and the daily production capacity was increased from 654.38+10,000 tons to 200,000 tons. At the same time, several underground water plants, such as Tiefeng, Jianhua and Longsha, were shut down, and most of the water supply in Qiqihar was converted into Nenjiang water.
