Lake water pollution prevention and control method and device

Abstract

The invention relates to a lake water pollution prevention and control method and a device; the device comprises a wastewater and sewage deep treatment and reuse station, a lake water circulating purification treatment station, an organic pyrolysis treatment station and a water pollution emergency treatment station. The method comprises the following steps: the wastewater and sewage are discharged into a sedimentation tank, and then conveyed to water treatment equipment by a water pump, and the water treated by the water treatment equipment is conveyed to a clean water tank to be reused; the lake water flows into a collecting tank through a grid arranged at a water intake, and then conveyed to filter equipment by the water pump through a water pipe; the water treated by the filter equipment flows into the water treatment equipment, and the water treated by the water treatment equipment flows into the clean water tank; and the water in the clean water tank is conveyed to a spray pipe by the water pump through a water return pipe paved in a lake, and sprayed out by a sprinkler head on the spray pipe.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a method and device for preventing and treating lake water pollution Background technique [0002] At present, 70% of the rivers and lakes in our country are polluted, the water surface of the lakes is shrinking, the functions are degraded, the water quality is polluted, and the structure of the lake ecosystem is damaged and out of balance. Internationally, lakes, especially shallow lakes, water pollution prevention and treatment is also a difficult problem. Lake water pollution is mainly due to the following reasons: [0003] 1) Due to the abundant water resources of the lake, the economic development around the lake and the continuous increase of urban population have led to a large increase in production and living water. When the water consumption in the lake area exceeds the replenishment of lake water, the water level of the lake will drop, the lake su...

AI Technical Summary

Problems solved by technology

[0003] 1) Due to the abundant water resources of the lake, the economic development around the lake and the continuous increase of urban population have led to a large increase in production and living water. When the water consumption in the lake area exceeds the replenishment of lake water, the water level of the lake will drop, the lake surface will shrink, and the wetland will decrease. , The environment becomes worse, and the carrying capacity and self-cleaning ability of the organic matter discharged into the lake are reduced

[0004] 2) A large amount of untreated wastewater and sewage from industrial enterprises, breeding enterprises and urban life around the lake are discharged into the lake, resulting in water pollution and eutrophication of the lake

[0005] 3) The water mobility of the lake is poor, especially in the shallow water and lake bay areas near the lake shore.

[0019] The above method has not been reported so far
