Environment-friendly domestic sewage treatment device and treatment method

Abstract

The invention discloses an environment-friendly domestic sewage treatment device in the technical field of domestic sewage treatment. A water inlet is formed in the top of a box body; the output end of the right side of a crushing motor is connected with a crushing rod through a coupler; a partition plate, a filter plate, a first filter layer and a second filter layer are sequentially arranged inan inner cavity of the box body from top to bottom; two groups of ultraviolet sterilization lamps are symmetrically mounted at the bottoms of left and right inner walls of the box body; a hollow rotating roller is mounted at the output end of a rotating motor. The device is simple to operate and environment-friendly; fine suspended matters, soluble small molecular organic matters, chromaticity, residual chlorine and other substances in sewage are filtered again through the first filtering layer and the second filtering layer; and finally, the filtered sewage is sterilized through the ultraviolet sterilization lamps, rotating brush bristles sweep the grounds everywhere in a family, the labor intensity of workers is effectively reduced, and the utilization rate of water resources is effectively increased.

Description

technical field [0001] The invention relates to the technical field of household sewage treatment, in particular to an environment-friendly household sewage treatment device and a treatment method. Background technique [0002] Sewage, usually refers to certain polluted discharge water from domestic and production. Sewage mainly includes domestic sewage, industrial wastewater and initial rainwater. The main pollutants of sewage are pathogenic pollutants, oxygen-consuming pollutants, plant nutrients and toxic pollutants. [0003] In some existing households, the water used for washing vegetables and dishes in the kitchen and washing in the bathroom is directly discharged through the sewer after use. When the family floor needs to be mopped, family members need to release water again to mop the floor, which causes water resources. The utilization rate of the sewage is poor, which seriously wastes water resources, causes excessive sewage to the environment, and also increases...

Problems solved by technology

[0003] In some existing households, the water used for washing vegetables and dishes in the kitchen and washing in the bathroom is directly discharged through the sewer after use. When the family floor needs to be mopped, family members need to release water again to mop the floor, which causes water resources. Poor utilization rate, serious waste of water resources, causing too much sewage to the environment, but also increased residents' water bills, for this reason, we propose an environmentally friendly household sewage treatment device and treatment method
