Self-cleaning recycling device for domestic wastewater treatment

Abstract

The invention discloses a self-cleaning recycling device for domestic wastewater treatment, the self-cleaning recycling device comprises a support plate frame, wherein the upper surface of the supportplate frame is fixedly connected with a filter stirring box; the inner wall of the filter stirring box is fixedly connected with a support block; the top of the support block is fixedly connected with a filter screen through a first bolt; the top of the filter stirring box is fixedly connected with a top cover plate through a second bolt; the middle part of the upper surface of the top cover plate is fixedly connected with a motor; the output end of the motor is fixedly connected with a stirring rod; and the middle part of the lower surface of the support plate frame is fixedly connected witha disinfection box. According to the self-cleaning recycling device for domestic wastewater treatment, impurities in wastewater can be filtered when the wastewater is poured through the matching arrangement of a clamping shaft, a supporting rod, a supporting groove plate, a rotating shaft, a screen frame and an impurity screen, then the impurity screen is reversed, and the impurities are poured into an impurity collecting cylinder, so that the self-cleaning recycling device for domestic wastewater treatment plays a role of filtering the impurities.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a self-cleaning recovery device for domestic wastewater treatment. Background technique [0002] Domestic wastewater is the wastewater discharged by residents in their daily life, mainly feces and washing sewage. The amount of domestic sewage discharged by each person in the city is 150-400L per day, which is closely related to the living standard. The sewage generated in the process of human life , is one of the main pollution sources of water bodies, mainly feces and washing sewage. Domestic sewage contains a large amount of organic matter, such as cellulose, starch, sugar and fat protein; it also often contains pathogenic bacteria, viruses and parasite eggs; inorganic salts Chloride, sulfate, phosphate, bicarbonate and sodium, potassium, calcium, magnesium, etc. The general feature is high nitrogen, sulfur and phosphorus content, and it is easy to produce harmful...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a self-cleaning recovery device for domestic wastewater treatment, which has the advantages of good filtering effect, good disinfection effect, good impurity removal, recycling, and strong practicability, and solves the problem of domestic wastewater treatment. The effect is relatively poor, and some domestic wastewater that does not meet the discharge standard after treatment will also be discharged to pollute the ecological environment, and the filtering effect is not good, the disinfection effect is poor, the removal of impurities is poor, and it cannot be recycled and has poor practicability. question
