Fully automatic building rainwater film separating and intelligent feedback back flushing system

Abstract

The invention discloses a fully automatic building rainwater film separating and intelligent feedback back flushing system. The fully automatic building rainwater film separating and intelligent feedback back flushing system comprises a roofing, a draining pipe, an impeller waste flow device, a sewerage pipe, a full flow energy storing device, a rainwater film separating device, an intelligent feedback back flushing device and a water storing device, wherein a filter net and the roofing are leveled and located directly above the draining pipe; the draining pipe is connected with the impeller waste flow device, and a waste flow pipe is arranged on the impeller waste flow device and is connected with the sewerage pipe; the full pipe energy storing device is mounted on the draining pipe, andwater flows filling the pipe can be guaranteed to enter the rainwater film separating device; and the intelligent feedback back flushing device and the rainwater film separating device are in mutual connection and cooperation for use, and finally, rainwater filtered by the rainwater film separating device is transmitted to the water storing device through the draining pipe. The fully automatic building rainwater film separating and intelligent feedback back flushing system realizes multiple functions of separating and purifying of roofing rainwater, rainwater storage and the like, so that thepurpose of high-quality rainwater is realized. The entire system is small in size, high in security coefficient and simple in structure, has an intelligent back flushing function, and is suitable forbeing promoted extensively.

Description

technical field [0001] The invention belongs to the technical field of rainwater collection and utilization, and in particular relates to a fully automatic building rainwater membrane separation and intelligent feedback backwashing system. Background technique [0002] my country is a country with very scarce water resources. According to incomplete statistics, more than 300 of the more than 600 cities in my country are short of water, and 108 of them are seriously short of water. The problem will only become more and more serious. At present, water shortage has become an important factor restricting the development of cities in our country and the improvement of people's living standards. But the paradox is that there are many high-rise buildings in my country's cities, with vast roofs, which can store a lot of rainwater, but most cities directly discharge the rainwater from the roofs of high-rise buildings to the ground. If this part of rainwater can be used, it can greatl...

[0004] Chinese patent publication number is 205676967U, and in the document named as a high-rise building rainwater recovery device, a kind of high-rise building rainwater recovery device is disclosed. The device is provided with a float valve to solve the problem of initial rainwater abandonment, but it does not affect the later stage. The rainwater is treated, and the quality of the later rainwater is relatively poor, and the content of COD and SS is still high

Chinese Patent Publication No. 105839755B, in the literature titled A Roof Rainwater Collection System, discloses a rainwater collection and treatment method, which solves the problem of initial rainwater abandonment and rainwater purification after treatment. However, the backwashing pressure of the device design is small, the backwashing effect is poor, the device structure is complicated and the cost is high, and the problems of backwashing failure and membrane damage are not considered, and the safety performance is poor and the stability is low.
