Urban sewage treatment device

Abstract

The invention discloses an urban sewage treatment device which comprises a first tank. The urban sewage treatment device has the advantages that urban sewage needing treatment enters a centrifugal filter tank through a sewage inlet, the centrifugal filter tank is driven to rotate by operation of a motor, particles are separated from water by the centrifugal filter tank, the sewage is thrown into afirst water storage tank, conveyed to a second water storage tank by a first water suction pump and filtered by a biological stuffing layer and a second filter screen and enters the bottom of the second water storage tank, the water is pumped to a third water storage tank by a second water suction pump and filtered by an activated carbon layer and a third filtering layer and then enters the bottom of the third water storage tank, the water is transferred to a fourth water storage tank by a third water suction pump and disinfected by an ultraviolet lamp, and then the treated water is drained by a drain outlet. The urban sewage treatment device is small in occupied area, high in treatment efficiency, strong in running stability, low in manufacturing cost and high in automation level, and can insulate noise and avoid affecting surrounding environments.

Description

technical field [0001] The invention relates to the field of sewage treatment equipment, in particular to an urban sewage treatment device. Background technique [0002] Water resources are the most critical resources for human production and life, but nowadays, the ecological environment has been severely damaged and water bodies are seriously polluted. The protection of water resources and the control of water pollution have become the most concerned issues in modern society. China suffers from water shortage, serious water pollution, serious soil erosion, low water price and serious waste of water resources. Moreover, there is more water in the south and less water in the north. There is less water in the west and more water in the coast. According to monitoring, groundwater in most cities across the country is currently subject to point and surface pollution to a certain extent, and there is a trend of increasing year by year. The increasingly serious water pollution ...

Problems solved by technology

[0003] At present, traditional sewage treatment technology is widely used. Sewage treatment is carried out step by step, usually consisting of multiple treatment units. The process is relatively complicated, the operation is cumbersome, the floor area is large, the treatment efficiency is low, the operation stability is poor, the energy consumption is high, and the cost is high. , the level of automation is low, and the noise generated seriously affects the surrounding environment
