Composite preparation microbiological, and preparation method

Abstract

This invention relates to a composite microbe preparation, which is composed of: photosynthetic bacteria group 2-3.8 wt.%, lactic acid bacteria group 0.6-1.8 wt.%, Saccharomyces cerevisiae 1-1.8 wt.%, Gram-positive bacteria group 1-3.8 wt.%, filamentous bacteria group 1-3.8 wt.%, culture medium 10-38 wt.%, and deionized water 65-80 wt.%. The preparation method comprises: performing amplification culture on the above bacteria separately to obtain production bacteria solutions, sealing in a stainless steel fermentation tank, adding deionized water and culture medium, inoculating the production bacteria solutions, fermenting until the pH is 3.8-4 and the living bacteria number is not less than 2X10 to the power 9, then packaging and storing. The composite microbe preparation can rapidly and effectively remove inorganic and organic pollutants in wastewater, denitrify, dephosphorize and inhibit algae growth by oxidation, reduction and fermentation.

Description

Technical field [0001] The invention relates to a composite microbial preparation and a preparation method, in particular to a biological preparation that uses a composite microbe to strengthen and activate a sewage treatment facility, a manufacturing method and a use method, and belongs to the technical field of sewage treatment. Background technique [0002] At present, the high-concentration or difficult-to-treat sewage treatment process is a conventional biological process, namely the activated sludge process. The disadvantages of this sewage treatment process are: [0003] 1. Activated sludge is cultivated by using surplus sludge from a domestic sewage plant or adding manure. The microbial population of the sewage treatment system cannot meet the needs of wastewater treatment in terms of quality and quantity; [0004] 2. Because of the low efficiency of microbial treatment, it leads to large investment in infrastructure; [0005] 3. High requirements for the pretreatment of ...

AI Technical Summary

Problems solved by technology

[0003] 1. For the cultivation of activated sludge, the remaining sludge of domestic sewage plants or feces are added, and the microbial population of the sewage treatment system cannot meet the needs of wastewater treatment in terms of quality and quantity;

[0004] 2. Due to the low efficiency of microbial treatment, it leads to large investment in infrastructure;

[0005] 3. The pretreatment requirements for influent water are high, resulting in strict requirements for operating technology;

[0006] 4. The amount of agent added is directly proportional to the amount of treated water, and the agent consumption is relatively large;

[0007] 5. The aeration power consumption is very large, which aggravates the energy shortage and directly leads to high treatment costs;

[0008] 6. The treatment effect is unstable, and the adaptability of activated sludge to water quality changes is poor

[0009] The current biological treatment cannot achieve the expected effect, and sometimes even fails. This is mainly because the general wastewater treatment system is built with a certain kind of substance or a certain type of substance as the treatment goal. When the water quality fluctuates little, it can meet the However, when the treatment system is accidentally impacted by other toxic and harmful substances, it is difficult for the inherent microorganisms in the original system to quickly adapt to the changes in the wastewater, and even its activity is severely inhibited, resulting in death and disrupting the normal operation of the entire system

[0010] In addition, with the improvement of people's environmental awareness and environmental standards, some wastewater with complex composition, even if its COD has reached the discharge standard, but the toxic and harmful pollutants that are low in content but very harmful have not been removed.

[0011] Chinese patent CN1421402A "A microbial preparation and culture method for treating papermaking wastewater" discusses a method of cultivating and domesticating specific microorganisms capable of treating papermaking wastewater with a specific medium. This method has certain effects in a specific working environment. However, in actual sewage treatment projects, the sources and types of pollutants are very complex, and it is difficult to achieve the final degradation of pollutants only by a single dominant microorganism. In fact, no microorganism can degrade all pollutants

[0012] Chinese patent CN1462728A "Technology of using microorganisms to treat sewage" describes a three-stage treatment process using microorganisms to treat sewage, but its disadvantages are that it takes more than 30-60 days, the total amount of microorganisms used is large, and the use cost The technical requirements for debugging and debugging are very high, and they are not practical. They will not be widely adopted by environmental protection companies and users in actual projects.
