Compound microbiological preparation

Abstract

The invention discloses a compound microbiological preparation. The compound microbiological preparation comprises microorganisms and bio-enzyme, wherein the microorganisms contain bacillus subtilis,bacillus licheniformis, nitrosomonas, nitrosospira brieusis, P.Aeruginosa, paracoccus denitrificans, lactobacillus plantarum, lactobacillus casei, candida utilis, saccharomyces cerevisiae, rhodopseudomonas palustris, rhodospirillum, aspergillus niger and enterococcus faecalis; and the bio-enzyme contains microbial enzyme and an aerobic microbial agent. The compound microbiological preparation disclosed by the invention does not contain chemical substances, and secondary pollution to an environment is avoided, and therefore, the compound microbiological preparation is an environmental-friendlymicrobial agent. The preparation process of the compound microbiological preparation has the advantages that the preparation process is simple, the production cost is low, and the compound microbiological preparation has wide prospects on restoration of eutrophicated water bodies.

Description

technical field [0001] The invention relates to the technical field of microorganisms, in particular to a composite microorganism preparation. Background technique [0002] Eutrophication of water body is a kind of nutrient substances such as nitrogen and phosphorus entering the slow-flowing water body in large quantities, causing algae and other plankton to multiply and grow in large numbers, causing the dissolved oxygen content in the water body to drop rapidly, and eventually leading to the death of fish and other aquatic organisms. Phenomenon. The water is usually black and has a foul smell. The eutrophic water body cannot rely on its own self-purification ability to achieve recovery. It is necessary to add various preparations and use water treatment facilities to strengthen the purification process of the eutrophic water body. [0003] The water purification methods of black water bodies mainly include three methods: physical method, chemical method and bioremediatio...

AI Technical Summary

Problems solved by technology

[0010] 3) After using chemical products, there will be residues in the water body, which may cause secondary pollution

These microbial strains are single, and the purification effect is limited; they do not produce spores during the survival period, and have poor environmental tolerance; some strains grow slowly, and the "activation" time is long during use. Both have problems

[0025] At the same time, the existing technical solutions have the following disadvantages: 1) the effect is poor under anaerobic conditions with insufficient oxygen, and the water purification results are not ideal; 2) the pH, temperature, and heavy metal content of the water body have a greater impact on the effect of the ecological restoration agent; 3) When the ecological restoration agent is put into the water body in the early stage, the chemical oxygen demand and ammonia nitrogen value in the water will be increased due to the biological enzymes (ie protein) in the ingredients; 4) In order to realize the wide versatility of the ecological restoration agent for water quality, a variety of Biological enzymes, increased production costs
