Biological fermentation composite treating agent for harmless treatment of sewage

Abstract

The invention discloses a biological fermentation composite treating agent for harmless treatment of sewage. The biological fermentation composite treating agent comprises raw materials including deacetylate chitin, tyrosinase, polyacrylamide, polyvinyl pyridine, compound microbial bacteria, enzyme microorganism, microbiological nutrient agent, folium eucalypti extracts, common ducksmeat herb extracts, tealeaf extracts, lauryl methacrylate, deacetylate chitosan, red non-sulfur bacteria and a demulsifying agent; by sufficiently utilizing the characters of mutual containment, backscratching and functional complementation among each component, macromolecular organic matters, artificially synthesized polymers and the like with poor biochemical property in sewage are decomposed into simple low-molecular-weight organic matters to the greatest extent, new trash or pollutants cannot be produced in a treatment process, the removal rate of ammonia nitrogen is high, and the concentration of BOD and COD can be effectively reduced; organic matters in the water can be automatically decomposed by microorganisms, the microorganisms can automatically get to a water surface to breathe oxygen, the produced sludge volume is little so as not to cause secondary pollution, the construction period can be shortened, and the comprehensive cost is reduced.

Description

technical field [0001] The invention relates to sewage treatment, in particular to a biological fermentation compound treatment agent for harmless treatment of sewage. Background technique [0002] With the continuous development of industry, the use of water resources has also increased, but there is less than 1% of fresh water on the earth, and only about 0.007% of the water can be directly used by humans. Therefore, water conservation and reuse Water resources have become the focus of attention. In the reuse of water resources, sewage treatment is the top priority. Domestic sewage is a kind of sewage with an increasing proportion in today's society, which has a great impact on the natural environment and human life. The content of nitrogen, phosphorus, and oil in domestic sewage is relatively high. Only physical methods and chemical agents are used. It often consumes a lot of manpower and material resources, and the effect is not obvious, and the use of a large amount o...

Problems solved by technology

[0003] In view of this, the object of the present invention is to provide a kind of bio-fermentation composite treatment agent for the harmless treatment of sewage, to solve the various pollutants discharged into the nature in the industrial production and life of the city, which exceeds the limit of the natural environment. Self-purification ability, and cause the nature and function of various factors in the natural environment to change, destroy the ecological balance, bring harm to human body, production and life and other urban environmental pollution problems
