Underground type micro power purifying tank sewage treatment equipment and treatment method

Abstract

The invention relates to the field of sewage treatment and discloses underground type micro power purifying tank sewage treatment equipment and a treatment method. The purifying tank sewage treatment equipment comprises an oil isolating pool, a facultative pool, an aerobic pool and a settling pool which are arranged in sequence and communicated in sequence through corresponding openings and water passing devices. Specially-made microorganism carrier filler, aerator pipes and sewage backflow and air lift pipelines are arranged in the facultative pool and the aerobic pool. A mixed liquor backflow and air lift pipeline and an overflow weir are arranged in the settling pool. While oil and water separation is achieved, floating oil is controlled within a certain water surface region, and therefore convenience is brought to follow-up clearing and sludge sucking; the dead water region of the facultative pool is reduced, the contact area between sewage and facultative microorganisms is increased, and time for contact between the sewage and the facultative microorganisms is shortened; membrane formation and growth situations of the microorganisms can be observed conveniently; oxygen transfer efficiency is improved, and meanwhile air holes can be prevented from being blocked; the sludge in the settling pool can flow back to the oil isolating pool well.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to sewage treatment equipment and a treatment method of an underground micro-power purification tank. Background technique [0002] With the development of rural urbanization and the improvement of economic level, the pollution caused by non-point discharge of scattered rural domestic sewage is becoming more and more serious. In areas where the urban sewage pipe network is difficult to reach, rural domestic sewage is directly discharged outside the house or into the receiving water body without treatment, resulting in a dirty and messy rural environment. [0003] Considering the factors of pipeline network investment and construction, it is advisable to adopt single-household or multi-household collection and treatment mode for scattered areas with dense river networks. If the distance between discharge points does not exceed 30 meters, they can be collected for relatively centraliz...

Problems solved by technology

However, due to the design problem of the water pipeline, many water treatment equipment often have dead zones during operation, resulting in unsatisfactory water outlet effects.
