Household sewage treatment equipment

Abstract

The invention relates to a piece of novel household sewage treatment equipment which is characterized by comprising a water inlet valve 1, a separation net 2, a clapboard 3, a blowoff valve 4, an exhaust valve 5, a filter layer 6, an air pump 7, a hollow fiber ultrafiltration membrane component 8, a membrane bioreactor 9, an air guide pipe 10, a water guide pipe 11, a water pump 12, a water level gauge 13, a water storage tank shell 14, an ultraviolet disinfection lamp 15, a water outlet valve 16, a sponge layer 17, a modified coal cinder layer 18, a quartz sand layer 19 and an active carbon layer 20. The household sewage treatment equipment uses the membrane bioreactor to treat sewage, pollutants are degraded in the membrane bioreactor to remove most of CODCr, BOD5, turbidity, NH3-N, total phosphorus and the like after passing through a filter (I) and a membrane bioreaction tank (II), and then the sewage is disinfected by the ultraviolet disinfection lamp so as to be stored in a recycled water reuse tank (III) to be used as household reuse water.

Description

technical field [0001] The invention relates to sewage treatment equipment, in particular to a household sewage treatment equipment using a membrane bioreactor. Background technique [0002] In the "Notice of the State Council on Printing and Distributing the Comprehensive Work Plan for Energy Conservation and Emission Reduction", it is clearly stated that the degree of reuse of household sewage should be greatly improved. Household sewage reuse is a basic method developed from residents' lives. In daily life, urban residents are not very aware of water conservation. Usually, sewage flows directly into sewage pipes through sewer pipes, causing most of the water to be washed away without being fully utilized, resulting in a large amount of water consumption in the family. If the water in it can be recycled, such as collecting the sewage such as washing vegetables, laundry, bathing, washing and so on, which consumes a lot of water in family life, and adopting the process of "...

AI Technical Summary

Problems solved by technology

At present, household sewage treatment equipment generally has problems such as complicated operation, low sewage purification rate, and large floor area. This equipment is not only easy to operate, but also can make full use of water resources, effectively use land, reduce household water consumption, and alleviate water shortage
