Microbial agent for purifying sanitary sewage and preparation method of microbial agent

Abstract

The invention discloses a microbial agent for purifying sanitary sewage and a preparation method of the microbial agent. Active ingredients of the microbial agent is formed by mixing the following raw material bacteria including thiobacillus denitrificans, bacillus subtillis, bacillus licheniformis, bacillus polymyxa, lactic acid bacteria, nocardia amarae, denitrifying bacteria, rhodopseudomonas palustris, thiophilic red pseudomonas, rhodospirillum, saccharomycetes and propionibacterium. By means of the microbial agent, cellulose, saccharides, fat protein, pathogenic bacteria, viruses and parasitic ovum in sanitary sewage and pollutants, such as inorganic salt which is high in the contents of nitrogen, sulphur and phosphorus, the BOD and COD removal effect is guaranteed, meanwhile good bactericidal ability is achieved, high inhibiting ability is achieved especially for pathogenic bacteria, and the effect of treating sanitary sewage is remarkable.

Description

Technical field [0001] The invention relates to a microbial inoculum, in particular to a microbial inoculum for purifying domestic sewage and a preparation method thereof. Background technique [0002] Urban environmental supervision is one of the important responsibilities of urban management personnel. At present, urban environmental pollution, especially water pollution, has always been one of the hazards related to people's vital interests. Sewage produced in the life process is one of the main pollution sources of water bodies. Mainly manure, washing sewage, garbage sewage. The amount of domestic sewage discharged per person per day in the city is 150-400L, and its amount is closely related to the standard of living. At present, the treatment methods of municipal solid waste widely adopted at home and abroad mainly include sanitary landfill, high-temperature composting and incineration. The proportions of the three main garbage disposal methods vary depending on factors s...

AI Technical Summary

Problems solved by technology

The characteristics of pathogenic microorganisms are: ① large number; ② wide distribution; ③ long survival time; ④ rapid reproduction; Some pathogenic microorganisms and viruses can still survive in large quantities; such pollutants actually enter the human body through various channels and survive in the body, causing human diseases

[0006] 2. Aerobic organic pollution

[0008] 3. Eutrophication pollution

[0010] 4. Stench

The hazards of stench are as follows: ① hinder normal respiratory function and reduce digestive function; mental irritability, reduced work efficiency, reduced judgment and memory; working and living in a foul smelling environment for a long time will cause olfactory disturbance, damage the central nervous system and cerebral cortex ② Some aquatic products are contaminated with stench and cannot be eaten or sold; ③ Smelly water cannot be used for swimming, fish farming or drinking, which destroys the use and value of water; ④ It can also produce hydrogen sulfide, formaldehyde, etc. toxic hazard

[0012] 5. Acid, alkali and salt pollution

[0014] 6. Increased groundwater hardness

[0016] 7. Toxic substance pollution

However, the current microbial agents are mainly used to treat industrial sewage and river sewage, and the sewage treatment capacity for daily life is weak, mainly because domestic sewage contains a large amount of organic matter, such as cellulose, starch, sugar and fat protein; It also often contains pathogenic bacteria, viruses and parasite eggs; inorganic salts such as chloride, sulfate, phosphate, bicarbonate and sodium, potassium, calcium, magnesium, etc., are generally characterized by high nitrogen, sulfur and phosphorus content. , under the action of anaerobic bacteria, it is easy to produce malodorous substances
