A municipal rainwater regulation and storage device and its working method

Abstract

The invention discloses a municipal rainwater regulation and storage device and a working method of the municipal rainwater regulation and storage device. The municipal rainwater regulation and storage device comprises a water collecting tank buried in the soil, a primary water filtering device, a secondary water filtering device, a tertiary water filtering device, and water-permeable pavement bricks paved on the surface layer of the soil, wherein the primary water filtering device, the secondary water filtering device and the tertiary water filtering device are of the same structures, each ofthe primary water filtering device, the secondary water filtering device and the tertiary water filtering device comprises a water filtering tank buried in the soil and a bracket, a motor is mountedon the top of each bracket, a screw rod is connected to the bottom output end of each motor, a support plate is connected to the bottom end of each screw rod, a threaded sleeve is arranged on the topsurface of each support plate, a filtering barrel sleeves the outer part of each threaded sleeve, and the filtering barrels are correspondingly filled with gravel, fine sand and activated carbon, respectively, and a first water pump, a second water pump and a third water pump are arranged on the top surfaces of the water-permeable pavement bricks. According to the municipal rainwater regulation and storage device and the working method of the municipal rainwater regulation and storage device, a multi-layer filtering system is adopted, so that the muddy rainwater is changed into recyclable clean water, and thus the collection and regulation as well as storage of rainwater are realized; a lifting device is adopted, so that the removal of sediment impurities and replacement of filtering fillers are facilitated.

Description

technical field [0001] The invention relates to the technical field of water supply and drainage equipment, in particular to a municipal rainwater regulation and storage device and a working method thereof. Background technique [0002] At present, the rainwater utilization regulation and storage device is mainly used for the collection and recycling of rainwater in the community, which plays an important role in saving water and relieving urban water pressure. Because the collected rainwater carries a lot of sludge and waste particles, over time, a thick layer of dirty sediment will accumulate at the bottom of the rainwater storage tank, which is difficult to remove. Therefore, it is necessary to introduce a rainwater storage and utilization device with relatively simple structure, convenient maintenance, low investment cost, and effective filtration of impurities in rainwater, so as to solve the problems of difficult initial rainwater treatment and difficult discharge and ...

Because the collected rainwater carries a lot of sludge and waste particles, over time, a thick layer of dirty sediment will accumulate at the bottom of the rainwater storage tank, which is difficult to remove

For this reason, it is necessary to introduce a rainwater storage and utilization device with relatively simple structure, convenient maintenance, low investment cost, and effective filtration of impurities in rainwater, so as to solve the problems of difficult initial rainwater treatment and difficult discharge and reuse.
