Rainwater treatment system

Abstract

The invention discloses a rainwater treatment system. Rainwater is purified multiple times by setting a purification room and setting a multi-layer purification screen in the purification room, by setting an operation room, an operator can easily replace or clean a blocked screen in the operation room, a buffer tank is arranged so that the pressure of a storage tank can be reduced and the rainwater can be prevented from overflowing in the storage tank, the buffer tank can be used for realizing the reuse of the rainwater with different purification degrees, an anti-floating device is arranged to prevent residual debris from floating and being discharged from a water suction pipe along with the rainwater, the rainwater and the residual debris are isolated, and the purification effect is further achieved.

Description

technical field [0001] The invention relates to the technical field of municipal engineering rainwater treatment, in particular to a rainwater treatment system. Background technique [0002] The drainage system of urban roads is an integral part of urban infrastructure, which plays a very important role in vehicle driving, traffic safety of people coming and going, urban environmental protection and urban flood control and drainage; efficient drainage can accumulate a large amount of water on the ground The rainwater is drained into the underground drainpipe, and then discharged into the water storage system through the drainpipe or purified; the existing rainwater often needs to be purified multiple times after entering the drainpipe to form purified water accumulation or discharge for reuse; but the existing technology The purification efficiency of the purification device is not high, and the purification device is easy to block and accumulate debris during the purificati...

[0002] The drainage system of urban roads is an integral part of urban infrastructure, which plays a very important role in vehicle driving, traffic safety of people coming and going, urban environmental protection and urban flood control and drainage; efficient drainage can accumulate a large amount of water on the ground The rainwater is drained into the underground drainpipe, and then discharged into the water storage system through the drainpipe or purified; the existing rainwater often needs to be purified multiple times after entering the drainpipe to form purified water accumulation or discharge for reuse; but the existing technology The purification efficiency of the purification device is not high, and the purification device is easy to block and accumulate debris during the purification process. After the blockage, the purification device is not easy to clean and replace; and no matter how many times of purification, there will always be some impurities that have not been filtered, and These impurities will enter the storage room with the rainwater; and when the subsequent rainwater purification is in use, these remaining impurities will affect the use of purified water
