Problems solved by technology

According to the transmission mode of surface runoff in the grass-planting ditch, the grass-planting ditch is divided into three types: standard transmission grass-planting ditch, dry grass-planting ditch and wet-planting grass-planting ditch. The wetland treatment system provides water for the grass planting ditch system through the reservoir, but the reservoir is dug directly in the soil, which is permeable and easy to be polluted

Abstract

The invention relates to a water storage mechanism for a wet-type grassed swale system. The water storage mechanism comprises a reservoir, wherein a cover plate is arranged on the reservoir; a plurality of liquid passing channels are uniformly formed in the cover plate; a layer of filter screen is arranged on the upper surface of the cover plate and a layer of filter screen is arranged on the lower surface of the cover plate; the reservoir is connected to a water purifier by virtue of a water discharging pipeline; the water purifier is connected to a water feeding pipeline; a water pump is arranged on the water feeding pipeline; and an anti-seepage layer is arranged on the inner wall of the reservoir. The water storage mechanism is applicable to the canal-type wet-type grassed swale system; and the water storage mechanism is good in anti-seepage performance and is capable of effectively controlling urban runoff non-point source pollution.

Description

technical field [0001] The invention relates to a water storage mechanism, in particular to a water storage mechanism for a wet grass planting ditch system. Background technique [0002] With the acceleration of urbanization in China, the increase of urban hard roads has led to increasingly prominent problems of urban waterlogging and non-point source pollution. [0003] Urban non-point source pollution refers to the environmental problems caused by rainwater and runoff scouring the urban ground under the condition of precipitation, causing pollutants to enter the receiving water body. Among them, the most important pollutants are suspended particles SS, chemical oxygen demand COD, total nitrogen TN, total phosphorus TP and heavy metal ions, etc.; due to the increase of the proportion of impervious ground, rainfall runoff has the characteristics of large water volume and poor water quality, resulting in surface The occurrence of source pollution is sudden. [0004] Therefo...
