A New Type of Rainwater Sedimentation Filtration Shaft

Abstract

The embodiment of the invention discloses a novel rainwater precipitating and filtering vertical shaft which comprises a shaft cover, a shaft barrel and a shaft bottom. A replaceable rainwater pollutant intercepting hanging basket in the shaft and filtering screens with pipe clamps arranged on two sides are arranged in the shaft barrel; the vertical shaft belongs to a novel rainwater precipitating and filtering shaft integrating precipitating and filtering; rainwater enters the shaft through a collecting pipe; impurities with large volume can be precipitated in the rainwater pollutant intercepting hanging basket; rainwater passes through the filtering screen; secondary separation is performed to part of precipitates and floaters, so that the rainwater is filtered;then the rainwater enters a reservoir through a water collecting pipe. The automatic filtering filter is flexible to install and convenient to use, has a simple structure and a wide application range, and can precipitate and filter rainwater collected through the collecting pipe, collect rainwater with good water quality into the reservoir, reduce the sand content of rainwater in subsequent rainwater pipes, reduce the content of rainwater pollutant in subsequent rainwater storage and processing facilities, improve the cleanliness of rainwater, and reduce the subsequent processing cost of rainwater.

Description

technical field [0001] The invention relates to the field of filtering shafts, in particular to a novel rainwater sedimentation filtering shaft. Background technique [0002] my country is a country with relatively poor water resources and extremely uneven temporal and spatial distribution. Due to the difference in the distribution of water resources and the increasing pollution of water resources in our country, many cities in our country are facing serious shortage and shortage of water resources. A large amount of land in the city is covered by hardened and impermeable materials, and the rainfall is discharged through the rainwater drainage system. The inspection wells in the rainwater system only have maintenance functions, and cannot filter out some impurities from the rainwater precipitation, and cannot collect relatively clear water to enter the storage. in the pool. [0003] Therefore, the collection and utilization of rainwater is becoming more and more important,...

AI Technical Summary

Problems solved by technology

The originally clean rainfall is affected by roads, squares, roofs and even airborne dust, making it rich in a large number of impurities and pollutants, resulting in poor water quality in the early stage

Such water quality not only affects the collection and storage of rainwater, but also increases the production cost of subsequent treatment of collected rainwater
