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 trench-type wet grassed swales system. The system comprises a dust layer, a grit layer, a building block brick layer, a gravel layer, a plain soil compacting layer and a reservoir; a part of the upper surface of the dust layer protrudes upwardly to form a vegetation layer, the other part of the upper surface of the dust layer downwardly concaves to form a ponding trench, the cross section shape of the vegetation layer and the ponding trench are in an arc-shaped structure, the grit layer, the building block brick layer, the gravel layer and the plain soil compacting layer are arranged from up to down, and positioned below the vegetation layer, the reservoir is arranged below the ponding trench, a cover plate is arranged on the reservoir, several liquid channels are uniformly arranged on the cover plate, a layer of filter screen is arranged on the upper surface and the lower surface of the cover plate, the reservoir is connected with a water purifier through a water outlet pipeline, the water purifier is connected with the dust layer through a water inlet pipeline, a water pump is arranged on the water inlet pipeline, so that the urban runoff non-point source pollution can be effectively controlled.

Description

technical field [0001] The invention relates to a grass planting ditch, in particular to a ditch-type 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] Therefore, how to control non...
