Sewage purification processing system

Abstract

The invention relates to a sewage purification processing system which sequentially comprises a grit chamber, an adjusting tank, an aerobic pond, an inclined plate sedimentation tank, a filtering tank, an ozone processing tank, wherein the bottom of the adjusting tank is provided with a preaerator, the aerobic pond is internally provided with a packing layer suspended in the middle part of the aerobic pond; an ozone oxidation pond is a plug-flow pool, and a water inlet pipeline of the ozone processing tank is provided with a pump and a venturi which are matched with each other; an outlet of the pump is connected with an inlet of the venturi, and a suction inlet of the venturi is connected with an ozone outlet of an ozonizer which adopts a plasma generator provided with an ozone air outlet;a plasma is provided with a high-voltage high frequency power supply circuit, and grille is arranged at the front par or in front of the grit chamber. The system has reasonable technique, good processing effect and lower cost, and the outlet water can be recycled in the life and industry.

Description

technical field [0001] The invention relates to a sewage purification treatment system, which is mainly used for treating domestic sewage and production sewage with low pollution degree and good biodegradability, and the treated water can be reused as non-drinking water. Background technique [0002] For domestic sewage and some industrial sewage with low pollution level, aerobic biochemistry is an effective and low-cost treatment method. Through the biochemical action of aerobic microbial flora, the organic matter in the water is decomposed into inorganic matter or simple substances. , and then separate the sludge and other solid particles and sols in the water by means of sedimentation, etc. Most of the other impurities in the water will also be separated and treated together with the sludge, but when used as non-quoted water for life and production, it is often still It is necessary to further purify the water after aerobic treatment. Various membrane treatment separation...

[0002] For domestic sewage and some industrial sewage with low pollution level, aerobic biochemistry is an effective and low-cost treatment method. Through the biochemical action of aerobic microbial flora, the organic matter in the water is decomposed into inorganic matter or simple substances. , and then separate the sludge and other solid particles and sols in the water by means of sedimentation, etc. Most of the other impurities in the water will also be separated and treated together with the sludge, but when used as non-quoted water for life and production, it is often still It is necessary to further purify the water after aerobic treatment. Various membrane treatment separations have been adopted in practice and have achieved good treatment effects. However, due to the relatively high cost of membrane treatment at present, it has affected the prospects for sewage reuse. development, so the combination of various processing technologies is still under constant discussion
