Environmental News Speed Review | Solo River, the former sewage river becomes a Qingshui River

In the early autumn, the rivers were sparkling, the water was clear, and the shallow water area in the lower reaches was the habitat of migratory birds. Many years ago, it was also criticized by the masses due to water quality problems.

The Twelfth Party Congress report of Tianjin proposed that carbon reduction, pollution reduction, greening, and growth coordinated, improved the level of ecological environment governance, and accelerated the construction of beautiful Tianjin. This year, Tianjin issued the "Entry and Entering the Sea Discharge Period Inspection and Remediation Work Plan", which continued to enter the river drainage port "Check, measure, trace, and rule", and gradually open up the management chain of "pollution sources -sewage channel -sewage outlets -water body" management chain Essence

In recent years, Tianjin has cured the pollution of rivers and reduces river pollution. It has paid close attention to the investigation, traceability, supervision, and rectification of the dirt discharge port, and implemented a series of water pollution prevention projects. "The quality of the sewage discharge of the river along the line has improved from all VI V in 2017, improved to all V type, and has reached more than 50%of this year. The class has gradually been promoted to Class V and IV. In the first half of this year, it was close to Class III, and from the past sewage to a pool of water. "Ma Li, director of the Water Ecological Environment Department of the Municipal Ecological Environment Bureau, told reporters.

Tianjin is located in the plain river network area of ​​"Nine River and Sanhui Haikou". The Municipal Ecological and Environment Bureau, the Municipal Water Affairs Bureau and other departments joined forces to investigate the sewage discharge port of all first, secondary rivers and large and medium -sized reservoirs in the city. Among them, the sewage channel is a key link to connect the source of pollution and enter the river. In urban construction areas, industrial gathering areas, and urban -rural binding departments. Most of the sewage is transmitted through hidden projects such as pipelines and culverts. "In order to trace the sewage passage, Tianjin has implemented a two -way traceability of the dirt and discharge port. The water department has exerted the advantages of river management and urban drainage management. The traceability traceability from the river channel to the source of pollution is promoted. Advantages, the starting point of pollution sources is advanced from the source of pollution to the river. The two departments are promoted simultaneously, sharing traceability information, and the results of the comparative visual traceability of the source of the traceability quality control system. "Ma Li said that the two departments also carried out separately. The water quality monitoring of the urban rainhrine mouth and the rainwater inspection wells made "double insurance" for precise traceability.

Tianjin is close to the bottom of the Bohai Bay. It is the main battlefield of the Bohai comprehensive governance battle. It is also the forefront of the Bohai River governance. Tianjin City promotes the improvement of water quality in the sea and rivers. Relying on the sewage outlets of the river to investigate the results, the Haihe, Ji Canal, Yongding Xinhe, and Qingjing Yellow Drainage canal enter the river and rivers. Pain in water quality improvement. At the same time, the management ideas of the surface water environment are pioneered to the management of the water environment in the river, and each monthly ranking and notifying the water quality in the river, which urge the ground to solve the problem of pollution of the upstream of the mouth. For example, in the coast of the river cultivation and aquaculture -breeding densely, Wangzhuangzhuang Town, Western Qing District uses abandoned farming pit ponds to build an "Xixi Sea" ecological wetland, using wetland to purify surface source pollution to create agricultural pollution to create agricultural pollution Governing Tianjin model. Tianjin has made great efforts in the monitoring, management, and governance of entering the river, and realized the tight connection of the improvement of the water quality improvement in the river into the sea, the systemic governance of the entire basin, and the pollution load of the entire river river. Twelve the water quality of entering the sea and river rivers from all in the past was inferior to the category. By 2020, it reached a category. By 2021, 11 have reached Category IV, which has achieved continuous leap -up improvement. With the improvement of the water quality of the sea in the sea, the Tianjin water ecosystem was recovered. Red -mouth gulls and silver gulls soared in the Haihe River.

In addition, Tianjin starts with the setting approval. By "uphill" in order to enter the river sewage outlet, it promotes the standardization of the sewage outlet management of the river, and formulates and introduced the "Operation Regulations for the Admission and Approval Service Services for Setting Evaluation Points". The approval time will be from 20th. Compression to the 8th, improving the approval efficiency. As of now, Tianjin has approved 165 urban sewage treatment plants and industrial enterprises in accordance with the law. The sewage port has been clearly defined one by one. "Tianjin will also fully check the sewage channels connecting the pollution discharge port and the source of pollution, the cities of the city of Yuhong discharge and the rectification of agricultural and rural areas, solve the pain points and difficulties such as error connection, mixing of rainwater pipe networks, and establish and improve the responsibility for clear responsibilities. Set up a reasonable and standardized long -term regulatory mechanism of pollutant discharge mouth, and effectively control the discharge of pollutants into the sea and the sea. "The relevant person in charge of the Municipal Ecological and Environment Bureau said.
