Pollution Sources (污染来源): domestic sewage (生活污水), domestic garbage (生活垃圾) livestock and poultry waste water (畜禽类便污水), tail water of sewage treatment facilities (污水处理设施的尾水), confluent pipe network sewage (合流制管网污水), air pollutants (大气污染物), agricultural and forestry non-point source pollution (农林面源污染), industrial pollution(工业污染)
Water environment governance is a comprehensive strategic social project with a large amount of engineering, a wide range of areas, and a complex situation. Water environment governance must "unify planning and step-by-step implementation; address both the symptoms and the root causes, focusing on curing the root cause; combining individual areas and focusing on the individual areas; focusing on actual results and simultaneous governance and management." In this way, the goal of improving the living environment, improving the quality of the city, and promoting sustainable economic and social development is achieved.
Project introduction: The Yuehong River section is 2 kilometers long, and the water quality pollution index is 16mg/lL of ammonia nitrogen, which is a severely black and odorous water body. The project treats water bodies of 20,000 m3/d, and reaches Class V standards on the surface after treatment. The lake cleaning technology adopts the column matrix purification composed of biological lake purifiers.
Project location: Lingbi, Suzhou; processing capacity: 20000t/d; technology used: biological lake purifier; influent water quality: severe black and odorous water body; effluent water quality: surface V-class standard; operating status: stable water quality.
Project introduction: Tuanjie River, Zhima River, and Consolidation Center River are 6.1 kilometers in total. The water quality pollution index is 8-32mg/L ammonia nitrogen, and the dissolved oxygen is less than 2mg/L, which is a serious black and odorous water body. The project treats 180,000 m3/d of water body, and reaches the surface class V standard after treatment.
Project location: Pukou, Nanjing; river length: 6.1 kilometers; technology used: biological lake purifier; influent water quality: severe black and odorous water body; effluent water quality: surface V-class standard; operating status: stable water quality.
With the specific and advanced technologies, the lake's wastewater treatment will get an excellent effect.
