Integrated rainwater treatment device

Abstract

The invention relates to an integrated rainwater treatment device. The device comprises a well body and a cover plate positioned above the well body; an overflow wall is arranged at the bottom of thewell body from bottom to top, and the interior of the well body is divided into a settlement area and a filter-permeation area by the overflow wall; a water inlet is formed in a cover plate arranged above the settlement area; a filter and permeation medium is laid at the bottom of the filter-permeation area; an overflow pipe is arranged at the upper part of the side wall of the well body at the filter-permeation area; a perforated drain pipe passing through the overflow wall is arranged between the settlement area and the filter-permeation area; the perforated drain pipe passes through the overflow wall and extends into the filter and permeation medium. The integrated rainwater treatment device provided by the invention is good in rainwater treatment effect, and can effectively reduce thepollution, caused by pollutants, to natural water. In a treatment process, the integrated rainwater treatment device can run without needing to be driven by external powder and does not influence normal flood discharge. The treated water can permeate in situ so as to supplement underground water.

Description

technical field [0001] The invention relates to a rainwater purification device, in particular to an integrated rainwater treatment device. Background technique [0002] With the acceleration of urbanization, the impermeable area on the ground has increased significantly, and pollutants have gradually accumulated on these impermeable ground. When it rains, the rainwater washes the ground and the pollutants are washed into the rainwater runoff system to form rainwater runoff pollution. Rainwater runoff pollution is a kind of diffuse pollution. Pollutants enter natural water bodies and cause water pollution. The pollutants include particulate matter, organic matter, heavy metals and other toxic and harmful substances. Therefore, the process of urbanization and industrialization has led to increasingly serious water crisis and rain and flood hazards. [0003] With the aggravation of water source crisis and rain and flood damage, it has become an important emerging topic to col...

Problems solved by technology

[0004] At present, the collection and treatment of initial rainwater in my country is still in its infancy. Collecting initial rainwater is only to prevent it from being discharged into the water body to pollute the water quality. However, little consideration is given to the purification and reuse of initial rainwater, and most of it is directly discharged into municipal domestic sewage pipes. network

The concentration of pollutants contained in the initial rainwater is relatively high, especially the initial rainwater on the road. Direct discharge into the domestic sewage pipe network will bring a greater load to the sewage plant
