Rainwater filtering and storage device

Abstract

The invention discloses a rainwater filtering and storage device. The rainwater filtering and storage device comprises a rainwater well, wherein the rainwater well is provided with a water inlet pipe, a water outlet pipe and a well lid, a partition wall with the suspending bottom is arranged in the rainwater well for separating the rainwater well into a rainwater collecting well and a filtering well, a seal cover is arranged on the top of the filtering well, a flow passing channel for communicating the rainwater collecting well and the filtering well is formed below the partition wall, the bottom of the filtering well is a slope gradually descending towards the bottom of the flow passing channel from the wall of the filtering well, the water outlet pipe is positioned on the wall of the filtering well, the water inlet pipe is positioned on the wall of the rainwater collecting well, the upper part of the filtering well is provided with a filtering structure which is positioned below the water outlet pipe, the bottom of the wall of the rainwater collecting well is connected with a mud sludge discharge pipe, and a sluice valve is arranged on the mud sludge discharge pipe. The reverse filtering structure is adopted inside the rainwater well, the structure is simple, the construction is easy, the filtering effect is obvious, and the filtering structure is easy to wash, clean and replace.

Description

technical field [0001] The invention belongs to the technical field of rainwater storage and utilization and water supply and drainage, in particular to a rainwater filtering and storage device. Background technique [0002] In recent years, the global climate has changed significantly, extreme weather has occurred frequently, cities have become prosperous, and waterlogging has occurred frequently. The shortage of water resources and serious pollution make our country face the crisis of water resources. In order to alleviate the pressure on the rainwater pipe network and save water resources, the urban stormwater management system that focuses on rainwater collection and utilization is being continuously improved. Rainwater from roads and roofs is an important source of rainwater collection, but the quality of rainwater needs to be improved. Most of the rainwater collection and utilization facilities at the present stage are equipped with initial rainwater abandonment faci...

AI Technical Summary

Problems solved by technology

At present, rainwater collection and utilization facilities are mostly equipped with initial rainwater abandonment facilities, which is complex in construction and high in investment costs

There are also rainwater collection facilities installed with filtration systems, which are easy to clog during the filtration process and difficult to clean
