Description

Catch dirty catch basin

Technical Field

The utility model relates to a municipal drainage technical field, concretely relates to intercept dirty rainwater well.

Background

The water environment is an indispensable component in the natural environment, and in recent years, with the rapid development of economy and society, water pollution events in China are frequent, and great harm is brought to the ecological environment and the health of residents.

At present, with the acceleration of black and odorous water treatment, urban point source pollution is gradually controlled, and the influence of non-point source pollution represented by urban runoff pollution on the water environment quality is increasingly shown. Non-point source pollution refers to other forms of pollution such as organic pollution and water eutrophication caused by dissolved and solid pollutants which sink into the receiving water body (including rivers, lakes, reservoirs and gulfs) from unspecified places under the scouring action of rainfall. Particularly, in the early stage of rainstorm, pollutants deposited on the ground surface and in the sewer pipe network are suddenly washed and converged into the receiving water body in a short time by rainfall runoff, so that the water body pollution is caused. According to observation, the pollutant concentration generally exceeds the ordinary sewage concentration in the early stage of rainstorm (20 min before rainfall), and urban non-point sources are main pollution sources causing water body pollution and have the characteristics of paroxysmal property, high flow, heavy pollution and the like.

In rainy days, garbage on the road surface, such as leaves, plastic bags, vegetable leaves and the like, enters the municipal rainwater drainage system along with rainwater runoff, is conveyed through a pipeline and finally discharged to a receiving water body along with a rainwater pipeline, and further causes adverse effects on water quality and environment of the water body. In the traditional rainwater drainage system, no matter the source and the conveying process of rainwater collection or the tail end of drainage, relevant sewage interception measures are lacked, so that garbage entering the rainwater system cannot be intercepted, and the garbage directly enters a water body.
