High-concentration chemical sewage composite inocula and use thereof

Abstract

The invention discloses high-concentration chemical sewage composite inocula. The high-concentration chemical sewage composite inocula comprise, by weight, 180-220 parts of bacillus cereus, 150-160 parts of bacillus circulans, 75-85 parts of Exiguobacterium acetylicum, 90-120 parts of bacillus coagulans, 150-170 parts of pseudomonas aeruginosa, 20-25 parts of micrococcus luteus, 120-140 parts of thiobacillus thiooxidans, 180-230 parts of rhodococci, 20-30 parts of lactobacillus brevis, 50-65 parts of paracoccus denitrificans, 95-112 parts of alcaligenes faecalis, 110-125 parts of pseudomonas putida, 100-130 parts of enterobacter aerogenes, 280-320 parts of beer yeast and 140-160 parts of lactobacillus fermenti. All strains of the composite inocula reasonably cooperate with each other, produce synergistic effects, do not produce antagonism, have a high survival rate, is suitable for one step addition and fast forms dominant bacterial community. The high-concentration chemical sewage composite inocula have unique treatment effects on high-concentration chemical sewage, have a COD clearance rate of 94.17%, reduce an operation cost and promote qualified discharge.

Description

technical field [0001] The invention belongs to the field of sewage treatment, and in particular relates to a formula of high-concentration chemical sewage compound bacterial agent. Background technique [0002] my country's environmental protection industry started relatively late, but has developed rapidly. At present, various wastewater treatment technologies and equipment manufacturing in the field of sewage treatment are advancing rapidly. A large number of large-scale wastewater treatment plants have been built in various industries across the country. (station), and achieved good environmental and social benefits. At the same time, my country's environmental protection industry is also facing many serious problems. Due to the eagerness for quick success, a lot of manpower and material resources are spent on process improvement, equipment modification and optimization of microbial growth environment in the process of introducing environmental protection technology, but ...

Problems solved by technology

At the same time, my country's environmental protection industry is also facing many serious problems. Due to the eagerness for quick success, a lot of manpower and material resources are spent on process improvement, equipment modification and optimization of microbial growth environment in the process of introducing environmental protection technology, but it plays a decisive role in biochemical treatment. Few people care about the microorganisms, so that AO method, AAO method, AOAO method, SBR method, CASS method, CAST method and many other sewage treatment processes have appeared one after another, and the patents and manufacturers of various fillers are too numerous to mention. However, there are still a considerable proportion of sewage treatment plants (stations) that cannot operate normally, especially in the field of high-concentration chemical sewage treatment. Most of the sewage treatment facilities built by production companies with huge sums of money are not in good condition. Not only the operating costs High, and still can not meet the standard discharge, still have to pay the excessive discharge fee to the local environmental
