Black and smelly river channel sinking type green space processing system and processing method

Abstract

The invention discloses a black and smelly river channel sinking type green space processing system and a processing method thereof. The system comprises river blocking water intake units, water diversion units and sinking type green spaces; the river blocking water intake unit is arranged at the upstream of a black and smelly river channel; each side of the black and smelly river channel is respectively provided with the water diversion unit and the sinking type green space, the water inlet of the water diversion unit is communicated with the water outlet of the river blocking water intake unit, and the water outlet of the water diversion unit is communicated with the water inlet of the sinking type green space; the surface of the sinking type green space is sequentially provided with a clay layer, a soil layer and a gravel layer from bottom to top, and aquatic plants are planted on the soil layer; the sinking type green space is provided with a water outlet, and the sinking type green space is used for treating sewage in the black and smelly river channel. The black and smelly river channel sinking type green space treatment system can be continuously applied for a long time, haslow cost, can give full play to the overall advantages, improves the purification treatment capacity of the river channel to a black and smelly water body, can improve the urban water body and the land landscape, and has obvious overflow effect.

Description

technical field [0001] The invention relates to the technical field of river ecological management, in particular to a black and odorous river sinking green space treatment system and a treatment method thereof. Background technique [0002] With the acceleration of urbanization, the ecological functions of my country's urban and rural rivers have become increasingly degraded due to human interference, and a large amount of land pollutants have been discharged, causing nitrogen, phosphorus, chemical oxygen demand (COD), and biochemical demand in most rivers to Oxygen (BOD) and other pollutants have seriously exceeded the standard, which has induced a series of environmental problems, such as eutrophication of river water, black and odorous rivers, decline of river biodiversity, river sediment garbage, river self-purification ability and degradation of water landscape functions Wait. Among them, river black and smelly is a key river environmental problem. River black and smell...

Problems solved by technology

[0005] According to the practice at home and abroad, none of the above-mentioned single technologies can fundamentally solve the problem of black and odorous rivers, and some of them will cause secondary pollution of water bodies, with low sustainable utilization and high cost
