Sewage purification device

Abstract

The invention discloses a sewage purification device. The device comprises a pretreatment component, a sterilization component, a purification component, a water storage tank, a water outlet, a liquidometer and an electric control cabinet. According to the device, through the arrangement of the pretreatment component, sewage enters the device from a raw water inlet pipe, a pretreatment filter screen pretreats impurities in the sewage, the impurities fall into a waste box, thus, the purpose of pretreatment is achieved, subsequent purification of the sewage is benefited, the purification effectof the purification device is improved, and the service life of the purification device is prolonged; a second valve is opened regularly to discharge the impurities in the waste box from a blow-off pipe, and thus normal running of the pretreatment component is guaranteed; and through the arrangement of the sterilization component and the purification component, when a button switch is pressed, a UV lamp performs sterilization on the sewage, then the sewage enters a purification box and is purified after passing through a primary filter screen, an activated carbon filling layer and a nanofiltration membrane layer, thus, the purpose of thoroughly purifying the sewage is achieved, purified water reaches a recycling standard, and waste of water resources is avoided.

Description

technical field [0001] The invention relates to the technical field of sewage purification, in particular to a sewage purification device. Background technique [0002] With the continuous development of society, more and more domestic garbage and sewage are continuously discharged into the river, which makes some rivers seriously polluted, and the river's sewage capacity is limited. The sediment in the inner bottom causes foul odor and pollutes the surrounding environment. The sewage in the river can be purified by the sewage purification device, but the existing sewage purification device lacks a pretreatment mechanism, and the sewage directly enters the purification mechanism, which affects the purification efficiency of the purification mechanism, and The service life of the purification mechanism is reduced, so it is urgent to develop a sewage purification device to solve the above problems and facilitate market promotion and application. [0003] The existing sewage p...
