Problems solved by technology

Non-point source pollution has become one of the main reasons for the deterioration of water quality. At the same time, rainwater runoff carries a large amount of pollutants into the urban water system and causes serious pollution.
[0003] At present, there are many ways to intercept initial rainwater, some of which use initial rainwater disposal devices, but no proper treatment method has been proposed for how t

Abstract

The invention provides a municipal rainwater storage system which comprises a rainwater pollutant intercepting facility, a rainwater lifting pump station and a rainwater storage pool. A bar screen, a rainwater lifting pump set, a submersible sewage pump and an electric room are arranged in the rainwater lifting pump station, a sewage pump is arranged in the rainwater storage pool and connected with a municipal sewage pipeline, a rainwater pump station water inlet pipe valve is arranged on a rainwater pipe between the rainwater pollutant intercepting facility and the rainwater lifting pump station, a rainwater storage pool water inlet valve is arranged on a rainwater pipe between the rainwater lifting pump station and the rainwater storage pool, a riverway water inlet valve is arranged on a rainwater pipe, connected to a riverway, of the rainwater lifting pump station, and the electric room is electrically connected with the rainwater storage pool water inlet valve, the riverway water inlet valve, the rainwater lifting pump set, the submersible sewage pump and the sewage pump. The municipal rainwater storage system can effectively control discharging of most surface pollutants and sewage and reduce pollution of rainwater at the early stage.

Description

technical field [0001] The invention relates to municipal rainwater collection and treatment technology, in particular to a municipal rainwater regulation and storage system. Background technique [0002] With the continuous increase in the proportion of urban sewage interception and treatment, point source pollution has been effectively controlled, and non-point source pollution caused by rainwater runoff has become the main factor of water pollution. Considering the discontinuous and explosive transport of runoff pollutants, the proportion of its pollution load will increase exponentially in a short period of time during the rainy season, surpassing point source pollution, causing impact on urban water bodies and seriously restricting the quality of urban water environment The thorough improvement of my country's rainwater runoff caused by pollution is also very serious. Non-point source pollution has become one of the main reasons for the deterioration of water quality. A...
