Biological agent for domestic sewage treatment

Abstract

The invention discloses a biological agent for domestic sewage treatment, and particularly relates to the technical field of sewage treatment. The microbial agent is prepared from the following raw materials in parts by weight: 8 to 10 parts of clostridium acetobutylicum, 12 to 16 parts of bacillus licheniformis, 16 to 20 parts of bacillus subtilis, 5 to 7 parts of lactobacillus acidophilus, 5 to 7 parts of methanosarcina, 3 to 5 parts of horsehair methane bacteria, 6 to 8 parts of rhodopseudomonas palustris, 4 to 6 parts of cellulomonas flavigena, 8 to 10 parts of streptococcus thermophilus, 8 to 10 parts of alcaligenes faecalis, 3 to 5 parts of bacillus amyloliquefaciens and 2 to 4 parts of nitrosomonas. The microbial agent containing various fungi, spore bacteria, bacteria, actinomycetes, aerobic microorganisms and anaerobic microorganisms can adapt to growth of thalli in an anaerobic environment with a high sewage degree and an aerobic environment with a low sewage degree, so that sewage with different degrees can be treated.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of sewage treatment, in particular to a biological bacterial agent for domestic sewage treatment. Background technique [0002] With the rapid development of human science and technology and economy, the environment has been severely damaged and polluted, which has seriously threatened people's health, so environmental protection measures to rectify various pollution are imminent. Water is the source of human life and is irreplaceable. However, at present, industrial wastewater and domestic sewage are discharged into natural water bodies, especially in rural areas where labor is cheap and a large number of factories are built, causing large-scale and large-scale pollution of various water bodies. [0003] The decomposition of organic matter in the polluted water body will consume a large amount of dissolved oxygen, resulting in severe anoxic or anaerobic water bodies, which will eve...

Problems solved by technology

[0005] To this end, the embodiment of the present invention provides a biological agent for domestic sewage treatment, through the synergy between various microorganisms, digests, absorbs or transforms organic and inorganic substances in sewage, thereby achieving the purpose of sewage treatment and improving The sewage treatment efficiency of the microbial agent is improved, and by providing the preparation method of the microbial attachment carrier for sewage treatment, the carrier can effectively attach the microbial bacteria, so that the microbial bacteria have better activity and are relatively fixed in place; the preparation method is simple , the prepared attachment carrier has good adsorption, so as to solve the problem in the prior art that a single biological bacteria can no longer cope with modern high-concentration and high-complexity sewage
