Domestic environment-friendly sewer sewage treatment device

Abstract

The invention discloses a domestic environment-friendly sewer sewage treatment device, and belongs to the field of sewer sewage treatment. The domestic environment-friendly sewer sewage treatment device belongs to an environment-friendly building material production sewage treatment device, and comprises a water inlet pipe, a fine filtering pool, a first anaerobic pool, an anoxic pool, an aerobicpool, a first membrane pool, a second anaerobic pool, an anoxic pool, a second membrane pool and a water outlet pipe, wherein the first anaerobic pool, the anoxic pool, the aerobic pool, the first membrane pool, the second anaerobic pool, the anoxic pool, the second membrane pool and the water outlet pipe are sequentially communicated; the other end of the water outlet pipe is connected with a pure water inlet of a centrifugal filtration device; an ultraviolet sterilization device is arranged in the water outlet pipe. Sewage is subjected to a series of sewage treatment processes, so that the comprehensive purification treatment on the sewage is realized; the sewage purification degree is improved.

Description

technical field [0001] The invention relates to the field of sewer sewage treatment, more specifically, to a family environment-friendly sewer sewage treatment device. Background technique [0002] The function of the aerobic pool is to allow the activated sludge to perform aerobic respiration, further decompose the organic matter into inorganic matter, and remove the pollutants. The function of the aerobic pool is to control the oxygen content and other requirements of the microorganisms. Only when microorganisms can perform aerobic respiration with the greatest benefit; anaerobic treatment uses the action of anaerobic bacteria to remove organic matter in wastewater, which usually takes a long time. The anaerobic process can be divided into hydrolysis stage, acidification stage and methanation stage ; [0003] The anoxic pool is relatively anaerobic and aerobic, and generally refers to a biochemical system in which the dissolved oxygen is controlled between 0.2-0.5 mg / l; w...

Problems solved by technology

[0004] After the sewage passes through the sewer, some sewage will stay in the sewer for a period of time, causing the sewage produced in the sewer to be fermented, smelly and disgusting, so the sewage treatment in the sewer is more important, because the longer the time, the more difficult it is to treat, and even Caking etc.
