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

Embodiment Construction

[0045] A detailed description will be given below in conjunction with the drawings. It should be pointed out that the equipment on the various trailers shown in the drawings is only an example, and the specific arrangement is not limited to the drawings.

[0046] The method of lake water pollution treatment and prevention consists of four parts, including: wastewater, sewage deep treatment and reuse ( figure 1 Shown), lake water cycle purification treatment ( figure 2 Shown), pyrolysis treatment of organic matter ( image 3 Shown) and emergency treatment of lake water pollution ( Figure 4-Figure 7 Shown).

[0047] See figure 1 Establish wastewater and sewage deep treatment and reuse stations around lakes and rivers. The wastewater and sewage deep treatment and reuse stations are composed of sedimentation tank 1, water pump 2, water treatment equipment 3, and clean water tank 4.

[0048] The wastewater and sewage that flow into the lake and its rivers, enterprises, cities, and rura...

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 specifically relates to a method and device for preventing and treating lake water pollution Background technique [0002] At present, 70% of my country's rivers and lakes are polluted. The water surface of the lakes is shrinking, their functions are degraded, and the water quality is polluted. The structure of the lake ecosystem has been destroyed and lost its balance. Internationally, lakes, especially shallow lakes, water pollution prevention and treatment is also a problem. The main causes of lake water pollution are as follows: [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 been promoted, and the production and domestic water consumption has also increased greatly. When the water consumption of the lake area exceeds the lake water supplement, the lake water level will drop, the ...
