Abstract

The invention relates to a method for treating sewage by adopting a biological-physical combined method. The method comprises the following steps of: making organic sewage water pass through an air floatation filter tank, a regulating pond, a zymolysis pond, an aeration biological pond and a product retention basin; and fermenting the organic sewage under the actions of microflorae, sludge, volcanic rock and the air, decomposing, purifying and the like to produce biologically active water which can be recycled in the growing process of animals and plants. The system has the advantages of capability of realizing full-automatic control, easiness in operating, small technical investment, low sewage treatment cost, high sewage treatment efficiency and stable performance.

Description

technical field

[0001] The invention relates to a method for treating sewage by a biological-physical combination method, in particular to a method for efficiently treating sewage formed by organically combining air flotation separation and microbial treatment.

[0002] The organic polluted water that can be treated by the present invention is all kinds of organic polluted water except for a small number of organic polluted waters that have a strong toxicity inhibitory effect on microorganisms, including large-scale breeding plants, casing processing plants, urban organic sewage, and high-concentration catering industry sewage and slaughterhouses, etc. Background technique

[0003] With the acceleration of urbanization, rapid economic growth and rapid population increase, in order to meet people's needs for material life, slaughterhouses, large farms, casing processing plants, and catering industries continue to increase in scale, which in turn leads to the discharge of orga...
