Efficient integrated rural sewage treatment device and sewage treatment method

Abstract

The invention discloses an efficient integrated rural sewage treatment device and a sewage treatment method. The efficient integrated rural sewage treatment device comprises a sedimentation tank, a treatment tank, a rotating mechanism and a stirring mechanism, the treatment tank is inserted into the upper portion of the sedimentation tank, a feeding hopper is inserted into the outer wall of the top of the treatment tank, and a conical filter screen plate is mounted at the top of the inner wall of the circumference of the treatment tank; and the circumferential outer wall of the treatment tank is sleeved with a first annular storage shell, water inlet holes distributed at equal intervals are formed in the joint of the first annular storage shell and the treatment tank, the water inlet holes are located above the conical filter screen plate, and the middle of the circumferential outer wall of the treatment tank is sleeved with a second annular storage shell. The conical filter screen plate is arranged in the treatment tank, large-particle impurities in domestic wastewater can be filtered, bristle rods on the hollow shaft can scrape the outer wall of the top of the conical filter screen plate, the large-particle impurities are prevented from being accumulated on the conical filter screen plate, and the filtering efficiency of the conical filter screen plate is improved.

Description

technical field [0001] The application relates to the technical field of sewage treatment, in particular to an efficient integrated rural sewage treatment device and a sewage treatment method. Background technique [0002] With the continuous advancement of my country's new rural construction work, farmers' attention to and requirements for the quality of the living environment have increased with the improvement of living standards, but the environmental pollution caused by domestic sewage in rural areas in my country has become increasingly serious. Rural sewage treatment refers to a method of rural sewage treatment. Rural life is increasingly urbanized, and domestic sewage mainly comes from toilet flushing water, kitchen washing water, washing machine drainage, shower drainage and other drainage. [0003] Domestic sewage in rural areas contains a large amount of large particles of impurities. Before treatment, the impurities need to be filtered, and then the sewage is se...

AI Technical Summary

Problems solved by technology

[0003] Domestic sewage in rural areas contains a large amount of large particles of impurities. Before treatment, the impurities need to be filtered, and then the sewage is sedimented. However, the filter screen is used for filtration now. Long use time will cause the filter screen to stick A large amount of impurities block the mesh holes and affect the filtering effect of the filter plate. Secondly, the sedimentation of the filtered sewage is achieved by adding chemicals. It needs a full mixing reaction between the chemicals and the sewage to make the sewage sediment fully. However, the current mixing mechanism has a poor mixing effect on chemicals and sewage, which leads to insufficient sewage precipitation and affects the treatment effect of sewage. Therefore, an efficient and integrated rural sewage treatment device and sewage treatment method are urgently needed to solve the above problems
