Rainwater recycling system and method

Abstract

The invention discloses a rainwater recycling system and method. The system comprises a drain tank, a grate, a first filter mechanism, a drain pipe, a first electromagnetic valve, a first connection pipe, a water collection tank, a second electromagnetic valve, a first liquid level sensor, a water storage tank, a second filter mechanism, a second connection pipe, a water pump, a second liquid level sensor, a supporting frame, a photovoltaic panel, a cabinet, a storage battery, a controller, a flow guide plate, connecting rods, a countersink, water inlet holes and a connection valve. The grateis arranged at the upper end of the drain tank, and clamping seats are fixedly mounted on the lower side of the grate corresponding to two side ends of the inner wall of the drain tank. A kettle coveris arranged at the upper end of an emulsification kettle body. By arrangement of the first filter mechanism, rainwater is scattered and slides downward along the peripheries of stage plates; by step-by-step arrangement of retaining plates, large-size impurities in rainwater are retained, so that primary filtration of rainwater is realized; by arrangement of a hanging connection structure of the first filter mechanism, quickness and convenience in impurity clearing are achieved.

Description

technical field [0001] The invention relates to the technical field of rainwater recycling, in particular to a rainwater recycling system and method. Background technique [0002] Due to the rapid development of urbanization and the expansion of impermeable areas such as roads and buildings, on the one hand, rainwater cannot penetrate into the ground to replenish groundwater, and the serious overexploitation of groundwater has deteriorated the water environment and ecological environment around the city. On the one hand, when there is heavy rain, the runoff quickly gathers to cause area accumulation of water and local floods in the city. The urban water shortage, the deterioration of the water environment, the destruction of the ecological environment, and the urban torrential rain and flood are becoming more and more prominent. Moreover, the city usually only has a drainage system and no collection system. When draining water, a large amount of water resources are wasted. T...

[0002] Due to the rapid development of urbanization and the expansion of impermeable areas such as roads and buildings, on the one hand, rainwater cannot penetrate into the ground to replenish groundwater, and the serious overexploitation of groundwater has deteriorated the water environment and ecological environment around the city. On the one hand, when there is heavy rain, the runoff quickly gathers to cause area accumulation of water and local floods in the city. The urban water shortage, the deterioration of the water environment, the destruction of the ecological environment, and the urban torrential rain and flood are becoming more and more prominent. Moreover, the city usually only has a drainage system and no collection system. When draining water, a lot of water resources are wasted. Therefore, it is necessary to design a rainwater recycling system and method
