Embodiment Construction

[0032] Such as Figure 1-9 Among them, an emergency treatment system for shallow lake sewage outlets, including a control area 3, a storage area 4 and a main lake area 5 set from the inside to the outside, and the control area 3, the storage area 4 and the main lake area 5 are respectively passed through different Water-permeable ecological barriers 11 are spaced apart, a grille 2 is provided on one side of the control area 3, and the grille 2 is connected to the lake outlet 1, and multiple floating beds 6 are provided on one side of the grille 2, and the control area 3 and the regulation and storage area Aquatic plants 7 are also provided in the 4, and the aquatic plants 7 are used for biomass accumulation. With this structure, the sewage from the lake outlet 1 can be purified and filtered after passing through the control area 3 and the storage area 4. The floating bed 6 and the aquatic plants 7 can effectively absorb and accumulate impurities in the sewage. After the water...

Abstract

The invention provides a shallow water type lake sewage port emergency treatment system which comprises a control area, a regulation and storage area and a main lake area which are arranged from inside to outside, the control area, the regulation and storage area and the main lake area are separated through impermeable ecological blocking pieces, a grating is arranged on one side of the control area and connected with a lake inlet discharge port, a plurality of floating beds are arranged on one side of the grating, aquatic plants are also arranged in the control area and the regulation and storage area and are used for accumulating biomass. The system is high in operability and simple to manufacture, and solves the problems that the lake sewage treatment is relatively complicated, the lake is easily influenced by a hidden discharge port, the water body quality is poor, and the use and maintenance are inconvenient.

Description

technical field [0001] The invention relates to the technical field of environmental engineering water environment treatment, in particular to an emergency treatment system for shallow water lake sewage outlets. Background technique [0002] Due to its unique geographical location and multi-functional characteristics, urban shallow lakes have a wide range of sources of pollutants, complex types, and more serious pollution, which has brought many hazards to the city and threatened the health of surrounding residents. Water environment treatment should firstly carry out source control and sewage interception. However, due to various historical reasons, there are many dark outfalls around shallow urban lakes, and sewage enters the lakes in severe weather such as heavy rains. Most of the urban shallow lakes are closed and slow-flowing water bodies. Small environmental capacity, poor self-purification ability of the water body, coupled with a large amount of sewage entering the l...
