Novel rainwater flow-dividing system for sponge city

Abstract

The invention relates to a novel rainwater flow-dividing system for a sponge city. The novel rainwater flow-dividing system comprises a water collecting device, the water collecting device comprises awater collecting well, the water collecting well communicates with a water inlet pipe, a drainage pipe and a main blow-off pipe, a filtering mechanism is arranged in the water collecting well, one end of the drainage pipe communicates with the bottom of the water collecting well, and the other end of the drainage pipe communicates with a water storage well at the same time; the main blow-off pipecommunicates with a sewage well; the filtering mechanism comprises a transversely-arranged filtering cylinder and a waste collecting tank fixed in the water collecting well, the filtering cylinder and the waste collecting tank are located at an upper opening of the water collecting well, one end of the filtering cylinder communicates with a water inlet pipe, the other end of the filtering cylinder communicates with the waste collecting tank, and a plurality of filtering holes are formed in the cylinder wall of the filtering cylinder in a penetrating mode; and the main blow-off pipe communicates with the bottom of the waste collecting tank, and a fixing part used for fixing the filtering cylinder is further arranged in the water collecting well. The novel rainwater flow-dividing system hasthe effects that the problems that rainwater directly drained into a river channel pollutes river water, and water resource waste is caused by direct drainage are solved.

Description

technical field [0001] This application relates to the technical field of urban rainwater treatment, in particular to a new type of rainwater distribution system for sponge cities. Background technique [0002] Sponge city is a new generation of urban stormwater management concept. It means that the city can be like a sponge and has good elasticity in adapting to environmental changes and responding to natural disasters caused by rainwater. It can also be called "water elastic city". Its main function is to absorb, store, infiltrate and purify water when it rains, release and use the stored water when needed, and realize the free migration of rainwater in the city, thereby achieving the purpose of alleviating urban waterlogging. [0003] At present, in order to achieve the purpose of quickly draining urban precipitation and reducing the probability of urban waterlogging, most of the drainage pipes are installed under the hardened road surface, and the water accumulated on th...
