Abstract

The invention relates to a method for preparing culture environment purifying agent by spore fermentation waste liquid, which is characterized in that the method comprises the following specific steps: 1. culturing compound strains to obtain compound bacteria, wherein the compound strains are composed of saccharomyces cerevisiae, lactobacillus plantarum, 5 hundred million/ml streptococcus lactis and rhodopseudomonas palustris; 2. decentralizing spore fermentation waste liquid produced when preparing lichens or litter spore microbiological feed additive, adding 5-10wt% of molasses into the obtained supernatant, then inoculating 1-10wt% of compound bacteria, and fermenting in a sealed environment at the temperature of 20-35 DEG C to obtain water body purifying agent. The method of the invention not only can obtain the purposes of reducing emission and protecting environment, but also can fully utilize nutrient components in waste liquid to produce culture environment modifier, thus saving cost and water resource. The invention has the outstanding characteristics of simple and easily realized operation, low operation cost and the like and is easy for industrial application.

Description

technical field [0001] The invention relates to a method for preparing a breeding environment purifier by using spore fermentation waste liquid, and belongs to the technical field of environmental improvement and environmental protection. Background technique [0002] Bacillus is considered to be able to secrete various enzymes such as protease. Decompose a large amount of residual bait, excrement waste, animal and plant residues, and harmful gases such as ammonia and hydrogen sulfide accumulated in the breeding environment into small molecular polypeptides, high-level fatty acids, etc., and then decompose into smaller molecular organic substances such as amino acids, low-level fatty acids, and simple Sugars, cyclic hydrocarbons, etc. are finally decomposed into carbon dioxide, nitrates, sulfates, etc., which can reduce the pollution of livestock and poultry pens, eliminate the odor of pens, and help create a good and comfortable breeding environment. When used in aquacultu...
