Embodiment

[0034] Such as figure 1 As shown, the polluted river restoration and maintenance system of the present invention includes a bank-based interception purification area 1, an ecological breeding area 2, an ecological planting area 3 and a natural function area 4.

[0035] The bank-based interception and purification area 1 is set on both banks of the river. On the basis of following the principles of biodiversity, adaptability and locality, select a site with strong removal capacity for nutrients such as nitrogen and phosphorus, high slope protection capacity, and certain economic value. plants, build a bank-based interception and purification area combining trees, shrubs and grasses on both sides of the river; the function of the bank-based interception and purification area is to filter and intercept farmland non-point source pollutants on both sides of the river, maintain river bank stability, and prevent river bank erosion; the bank-based interception Purification zone 1 incl...

Abstract

The invention relates to a polluted river restoration and maintenance system, which comprises a shore-based interception purification area, an ecological culture area, an ecological planting area anda natural functional area. The shore-based interception purification area is disposed both river banks, and consists of a sub-normal water level plant zone, a plane zone between the normal water leveland a flood level, and a plant zone above the flood level. The ecological culture area is disposed in the river and is constructed according to the natural shape of the river, and consists of an upstream debris-retaining dam, surface aerators, a biological carrier, a microbial agent feeder, a downstream storage dam, an interception net, and a solar and wind power generation device. The ecologicalplanting area is disposed in the river and is constructed according to the natural shape of the river, and is internally equipped with a plant floating bed. The water area except for the ecological culture area and the ecological planting area of the polluted river is set as a natural functional area, and the natural functions of the river itself are utilized for self-purification of the river water and propagation of organisms.

Description

technical field [0001] The invention relates to water environment treatment technology watersheds, in particular to a polluted river restoration and maintenance system. Background technique [0002] Due to the discharge of industrial wastewater and domestic sewage, as well as the accumulation of pollutants in the river environment caused by the runoff of rainwater on both sides of the river and the receding water of farmland, the degree of pollution of the river has continued to increase. Many rivers have almost lost their self-purification ability, and the water environment has deteriorated day by day. . [0003] The existing methods of river governance mainly include physical methods, chemical methods and ecological restoration methods. Each method has advantages and strengths, but also has shortcomings and defects. At the same time, many rivers are polluted after being treated, and then treated and polluted again and again. [0004] As people's awareness of the ecologic...
