Embodiment 1

[0086] A compound microbial bacterial agent for the treatment of black and odorous water bodies, the compound microbial bacterial agent includes complex bacteria and a composite enzyme preparation, and the complex bacteria include Candida tropicalis, Candida utilis, Bacillus natto , Bacillus subtilis, Bacillus licheniformis, Nitrobacter, denitrifying bacteria, Nitrosobacillus, Acinetobacter, Lactobacillus, Aspergillus niger, Aspergillus oryzae, photosynthetic bacteria, the compound enzyme preparation includes protease, amylase, fat Enzyme, sucrase, cellulase, wherein, according to the total mass of each component as 100%, their respective mass percentages are as follows: Candida tropicalis 3-5%, Candida utilis Yeast 3-5%, Bacillus natto 3-5%, Bacillus subtilis 7-10%, Bacillus licheniformis 5-8%, Nitrobacter 8-12%, Denitrifying bacteria 7-10%, Nitrosobacillus 5-12%, Acinetobacter 6-10%, Lactobacillus 3-5%, Aspergillus niger 3-7%, Aspergillus oryzae 3-6%, Photosynthetic bacteria...

Embodiment 2

[0088] A method for cultivating a compound microbial bacterial agent for black and odorous water treatment, comprising the following steps:

[0089] S11. provide 13 kinds of microbial strains and 5 kinds of enzymes according to the composition of the composite microbial bacterial agent provided in embodiment 1;

[0090] S12. According to the mass ratio of the composite microbial agent and the carrier (wheat bran, rice bran), the ratio is (15-20%): (80-85%), wherein the mass of wheat bran and rice bran in the carrier The ratio is 1:1, and the composite microbial agent and the carrier (wheat bran, rice bran) are uniformly mixed. Further, 3% Tianhui green juice, 3% raw fish amino acid, 4% sucrose nutrient salt, and 1% corn starch were added, and uniformly mixed to obtain a bacterial cell growth carrier. Naturally ferment for 3-5 days under the conditions of ventilation, 28-35 DEG C, and 65-70% moisture to obtain a compound microbial bacterial agent suitable for black and odorous...

Description

technical field [0001] The invention belongs to the technical field of environmental treatment, and in particular relates to a compound microbial bacterial agent for treatment of black and odorous water bodies, a cultivation method and a use method thereof. Background technique [0002] Black and odorous water body is a biochemical phenomenon. When the water body is severely polluted by organic matter, the aerobic decomposition of organic matter will cause the oxygen consumption rate in the water body to exceed the rate of reoxygenation, resulting in anoxic water body, resulting in incomplete degradation of organic matter and slowed down rate. During the biodegradation process, odorous substances such as hydrogen sulfide, amine, ammonia, and mercaptan are formed, and black substances such as FeS and MnS are formed at the same time, causing black and odorous water bodies. Black and odorous water body is a serious water pollution phenomenon, which completely loses the use func...
