Embodiment 1

[0013] A compound microbial preparation for inhibiting and killing cyanobacteria provided by the embodiment of the present invention is prepared from the following components by weight percentage: 35% of chicken manure extract, 60% of chaff powder and 5% of compound microbial agent;

[0014] Chicken manure extract is a solid product obtained by separating chicken manure from solid and liquid through a common solid-liquid separator and removing moisture.

[0015] The composite bacterial agent includes Bacillus subtilis, high-temperature actinomycetes, Enterobacter aerogenes and actinomycetes, the effective number of viable bacteria of said Bacillus subtilis is 1.9 billion / g, and the effective number of effective bacteria of said high-temperature actinomycete is 0.06 billion / g gram, the effective number of viable bacteria of the Enterobacter aerogenes is 0.1 million / gram, and the effective number of viable bacteria of the saccharomyces is 3-4 million / gram.

Embodiment 2

[0018] A compound microbial preparation for inhibiting and killing cyanobacteria provided by the embodiment of the present invention is prepared from the following components by weight percentage: 40% of chicken manure extract, 58% of chaff powder and 2% of compound microbial agent.

[0019] Chicken manure extract is a solid product obtained by separating chicken manure from solid and liquid through a common solid-liquid separator and removing moisture.

[0020] The composite bacterial agent includes Bacillus subtilis, high-temperature actinomycetes, Enterobacter aerogenes and actinomycetes, the effective number of viable bacteria of said Bacillus subtilis is 1.9 billion / g, and the effective number of effective bacteria of said high-temperature actinomycete is 0.06 billion / g. gram, the effective number of viable bacteria of the Enterobacter aerogenes is 0.1 million / gram, and the effective number of viable bacteria of the saccharomyces is 3-4 million / gram.

[0021] During the p...

Embodiment 3

[0023] Composite microbial preparation does not produce water bloom phenomenon in order to suppress the growth of cyanobacteria, every mu of water uses 4-5 kilograms of composite microbial preparations, the composite microbial preparations prepared by embodiment one is added 3 kilograms of brown sugar per hundred kilograms of composite microbial preparations before use, After mixing, add water with the same weight as the compound microbial preparation, mix evenly, and use it after standing for two hours. At the same time, use an aerator to add oxygen to the water body.

[0024] After using the compound microbial preparation for five days, use it again.

Abstract

The invention relates to a compound microbial preparation capable of inhibiting and killing blue-green algae. The preparation is prepared from the following components by weight percent: 35%-60% of chicken manure extract, 35%-60% of rice husk powder, and 2%-5% of complex microbial inoculants, wherein the complex microbial inoculants comprise bacillus subtilis, thermoactinomyces, enterobacter aerogenes and saccharomycetes, the effective viable count of the bacillus subtilis is 1,900 million/gram, the effective viable count of the thermoactinomyces is 6 million/gram, the effective viable count of the enterobacter aerogenes is 1 million/gram, and the effective viable count of the saccharomycetes is 3-4 million/gram. The problems that a method for eliminating cyanobacterial bloom in the prior art consumes a lot of manpower and material resources and easily causes secondary pollution are solved.

Description

technical field [0001] The invention relates to the field of water pollution control, in particular to a compound microbial preparation for inhibiting and killing cyanobacteria and its preparation and use method. Background technique [0002] At present, the pollution of many lakes leads to serious cyanobacteria blooms. The existing methods for removing cyanobacteria blooms generally include mechanical salvage methods or chemical agent killing methods. Mechanical salvage methods require a lot of manpower and material resources, which is not realistic in large lakes. ; The chemical agent killing method will often cause harm to other organisms in the lake, or cause secondary pollution after enrichment. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a compound microbial preparation for inhibiting and killing cyanobacteria and its preparation and use method, which solves the problem that the removal method of c...
