Problems solved by technology

After using flocculant to filter, the filtered pollutants are dewatered through compression or centrifugation machines, and the compressed or centrifuged pollutants are stored (the national law does not allow burial), which takes up a lot of space, and most waterworks use it. PAC is used as a flocculant, and the aluminum content in the effluent after treatment exceeds the standard seriously. How to decompose the substances in the sewage through microorganisms as much as possible and reduce the occupied space is an urgent problem to be solved.
[0003] Due to the characteristics of the sludge itself, its molecular structure is tight and the porosity is low. It is extremely difficult for ordinary beneficial fermentation bacteria to penetrate the sludge molecular group, and it is not easy for sludge biological fermentation.

example

[0024] 1. Aquaculture sewage contains a large amount of organic substances, lipids, fibers and a large amount of inorganic salt components, which are all substances required for the growth of microorganisms. The patented compound microorganisms and the enzymes produced by microorganisms can decompose these substances into small molecular substances , carbon dioxide and water, small molecules are further decomposed by a large number of microorganisms. Improve odor treatment efficacy and reduce COD, BOD and TSS.

[0025] 2. The complex microorganisms treat the sewage discharged from the paper mill. The data before and after treatment are:

[0026] water sample CODcr (mg / L) NH3-N (mg / L) Chroma (multiplier) Turbidity (NTU) pH before processing 15000 300 8000 3600 8.0 after treatment 305.6 56 100 102 7.0

[0027] The use of compound microorganisms has an obvious effect on the treatment of harmful substances in water, and the effect of deo...

Abstract

The invention relates to a composite microorganism formulation. The compound microorganism formula is prepared from the following raw materials in percentage by weight: 36 to 44% of bacillus subtilis,8 to 12% of moss bacteria, 9 to 11% of polymyxa, 7 to 9% of aspergillus, 3 to 6% of nocardia, 1 to 5% of protease, 3 to 5% of digestive enzyme, 3 to 7% of saccharomycetes, 4 to 7% of cellulase, 6 to8% of actinomycetes and 3 to 5% of amylase. The compound microorganism formula provided by the invention contains a plurality of aerobic and anaerobic microorganisms, the microorganisms generate a plurality of enzymes, unpleasant odor is eliminated, harmful microorganisms are inhibited, the content of BOD and COD in leachate in excrement is reduced, the subsequent treatment load is reduced, and the compound microorganism formula is suitable for sewage treatment of industry, agriculture, life and the like and has a wide application range.

Description

technical field [0001] The invention relates to the technical field of microbial enzymes, in particular to a compound microbial formula. Background technique [0002] At present, flocculants are mostly used for industrial, agricultural, and domestic sewage treatment. Sewage treatment is divided into three stages. The primary treatment mainly removes suspended solid pollutants in sewage. Removal of colloidal and dissolved organic pollutants (BOD, COD substances) in sewage; tertiary treatment, treatment of sewage by activated carbon adsorption, sand filtration, etc. After using flocculant to filter, the filtered pollutants are dewatered through compression or centrifugation machines, and the compressed or centrifuged pollutants are stored (the national law does not allow burial), which takes up a lot of space, and most waterworks use it. PAC is used as a flocculant, and the aluminum content in the effluent after treatment exceeds the standard seriously. How to decompose the s...
