Problems solved by technology

In recent years, many cities have reconstructed some landscape rivers. However, due to incomplete interception of sewage and unresolved non-point source pollution, the ecosystem of the river has not been well restored. As time goes by, the water quality is difficult to maintain and presents a deteriorating trend. trend

Example Embodiment

[0013] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0014] figure 1 Is a schematic diagram of the process of the present invention,

[0015] figure 2 It is the floor plan of the present invention.

[0016] Such as figure 1 with figure 2 As shown, the present invention provides a method for composite restoration of eutrophic water bodies in landscape rivers, which is carried out in sequence as follows:

[0017] 1). Laying impervious membrane: Lay the impervious membrane on the bottom and sides of the river, and fix both sides on the bank to cover the bottom mud of the river and prevent the release of internal source pollution of the bottom mud;

[0018] 2) Install artificial water purification plants: install artificial water purification plants at the bottom of the river, with the main part immersed below the surface of the water body. The water purification plants provide carriers for microorganism...

Abstract

The invention provides a landscape river course eutrophicated water body composite restoration method. The composite restoration method comprises the following steps: 1) laying an anti-seepage film; 2) installing artificial water purification grass; and 3) carrying out different-position purification. The landscape river course eutrophicated water body treatment method is simple to operate, has the advantage of quick effect taking, and is capable of enhancing the self-purification capacity of the water body, preventing the endogenous pollution of the river course sediment, and effectively solving the problem of eutrophication in the town landscape river course water body.

Description

technical field [0001] The invention relates to a method for treating eutrophication of a landscape water body, in particular to a method for composite restoration of a landscape river course eutrophication water body. Background technique [0002] With the acceleration of urbanization in my country, the problems of urban water environment have become increasingly prominent. Urban construction squeezes the water area, reduces the cross section of the river, and reduces the flood discharge capacity. Some industrial wastewater and domestic sewage directly enter the urban landscape water body, causing increasingly serious pollution. In recent years, many cities have reconstructed some landscape rivers. However, due to incomplete interception of sewage and unresolved non-point source pollution, the ecosystem of the river has not been well restored. As time goes by, the water quality is difficult to maintain and presents a deteriorating trend. trend. Due to the increasing eutr...
