A greening flat rainwater collection and reuse device

Abstract

The invention discloses a rainwater collection and reuse device for greening flats, which comprises a box body, the end face of the box body is connected with a water storage tank, and the box body is sequentially installed with a stone layer, an activated carbon layer, a gauze layer and a Ultrafiltration membrane, the lower end of the water storage box is connected with a water inlet pipe, a check valve is installed on the water inlet pipe, the lower end of the water inlet pipe is connected with a buffer box, and one end of the buffer box is connected with an outlet Water pipe, the end of the water outlet pipe is connected with a piston tube, the piston tube is connected with an L-shaped elbow, the L-shaped elbow runs through the box and is equipped with a booster valve, and the L-shaped elbow is far away from the box One end is equipped with a nozzle. The advantages are: the present invention has the functions of infiltration, filtration, storage, and drainage, reduces the runoff velocity of rainwater, effectively improves the infiltration of rainwater, improves the utilization rate of rainwater, coordinates the circulation of natural precipitation, surface water, and groundwater, and can also improve the environmental microclimate , reduce municipal drainage pressure, and save engineering construction costs.

Description

Technical field[0001]The present invention relates to the field of municipal engineering technology, in particular, involving a green ping rain, collecting and reuse.Background technique[0002]Since the 1970s, the international city's rain flood control concept has changed, rainwater storage, cushioning, utilization, etc. have become an important part of rainwater management, and many countries are committed to research and development of rainwater utilization technology, using legal, economic, technology With a variety of means, from the two angles of water and water quality, "ecological drainage" is implemented through engineering and non-engineering, and it has entered the natural water circulation process as much as possible, thereby reducing the rainwater of urban drainage systems to promote rain water. Resource utilization, reducing urban flood disasters, reducing urban sewage treatment load and construction cost, maintaining the ecological balance of urban water circulation, t...

Problems solved by technology

[0002] Since the 1970s, the concept of stormwater control in international cities has changed, and rainwater storage, slow discharge, and utilization have become important contents of rainwater management. From the perspective of water quantity and water quality management, implement "ecological drainage" through engineering and non-engineering measures to promote precipitation into the natural water cycle process as much as possible, thereby reducing the amount of rainwater entering the urban drainage system and promoting rainwater drainage. resource utilization, reduce urban flood disasters, reduce urban sewage treatment loads and construction costs, and maintain the ecological balance of urban water cycles. Traditional municipal drainage facilities are mainly hard canals, and rainwater is directly discharged to drainpipes to reduce rainwater infiltration , the rainwater is not used reasonably, resulting in a waste of resources
