Background

Water resources are used as non-renewable resources, the water resources are increasingly deficient, and the development and utilization of non-traditional water sources, rainwater and the like are another effective way for solving the problem of water resource shortage at present. The sponge city is a new generation of urban rainfall flood management concept, and means that the city has good elasticity in the aspects of adapting to environmental changes, coping with natural disasters caused by rainwater and the like, and can be also called as a water elasticity city, and the international general term is 'low-impact development rainwater system construction'. The sponge city can absorb, store, seep water and purify water when raining, the stored water is released and utilized when needed, and the functions of absorbing, storing and slowly releasing rainwater are realized in buildings, districts, roads, squares, parks, greenbelts, water systems and the like through source emission reduction, process control, system management and the like, so that rainwater runoff is effectively controlled, and the effects of no water accumulation in small rain, no waterlogging in heavy rain, no black and odorous water and relief in heat islands are realized. The sponge city emphasizes that rainwater treatment adopts means of 'seepage, stagnation, storage, purification, utilization and drainage', and roof rainwater is limited by adopting means of seepage and stagnation when the periphery of a rain drop pipe is a hard pavement and other areas.

The collected rainwater is often accompanied by silt and impurities, so that the content of the silt and the impurities in the rainwater is reduced, the improvement of the quality of the rainwater is a precondition for rainwater utilization, and at present, a rainwater collector is mostly adopted to remove the silt and the impurities in the rainwater.

The prior art situation is: rainwater is abandoned to flow through initial rainwater abandon class device and flows into rainwater former pond certainly after intercepting thick floater. The rainwater raw water pool has the second function, namely, sedimentation is carried out to remove inorganic particles such as silt carried in water; and secondly, flow adjustment is carried out, so that subsequent treatment facilities run under set parameters, and the full play of the decontamination efficiency is ensured. Lifting raw water in the rainwater raw water tank by a pump, entering high-efficiency fine filtration equipment, and selecting quartz sand filtration equipment; in the filter, the rainwater flows into a rainwater raw pool after being abandoned by the initial rainwater abandoning device and intercepted by the coarse floaters. The rainwater raw water pool has the second function, namely, sedimentation is carried out to remove inorganic particles such as silt carried in water; and secondly, flow adjustment is carried out, so that subsequent treatment facilities run under set parameters, and the full play of the decontamination efficiency is ensured. Lifting raw water in the rainwater raw water tank by a pump, entering high-efficiency fine filtration equipment, and selecting quartz sand filtration equipment; in the filter, under the mechanical sieving action of the filter material, solid particles in water are intercepted and removed. Filtered water enters an aeration balance water suction box, a sodium hypochlorite solution is added into a water tank by adopting an automatic dosing device, the treated water is sterilized and disinfected, and then the treated water is transferred to a clean water tank by a rainwater transfer pump, so that the treated rainwater meets the use requirement, and the water can be used for greening, road flushing and the like after being pressurized by the pump. As shown in fig. 1, in the existing water collection and purification device, rainwater collected by a roof is collected with rainwater on the ground through a rainwater collecting pipe (through the rainwater collecting pipe 1), then rainwater purification is carried out (the rainwater sequentially passes through a sewage interception hanging basket 2, a flow abandoning filter 3 and a rainwater filter 4 and reaches a water tank 5, a lifting pump 6 is arranged in the water tank 5, and the lifted water is used for vegetation irrigation, road flushing, vehicle washing and the like after passing through a purification integrated machine 7), so that the rainwater treatment capacity is large, and the treatment effect is general; and because roofing rainwater collection clean system sets up underground, need use the elevator pump.
