Compound microbial inoculum for sewage purification and preparation method thereof

Abstract

The invention relates to a compound microbial inoculum for sewage purification and preparation method thereof. The microbial inoculum contains bacillus, yeast, actinomycetes, and photosynthetic bacteria in a weight ratio of 10-30:20-40:10-20:40-60. The preparation method comprises the following steps: inoculating various bacteria to a shake flask containing a culture medium for activation culture, inoculating activated strains into a fermentation tank for amplification culture, and mixing various bacterial solutions subjected to the amplification culture in proportion to prepare the compound microbial inoculum for sewage purification. The compound microbial inoculum has strong adaptability, can rapidly form a dominant micro flora, can significantly reduce the indexes of COD, ammonia nitrogen, total phosphorus and the like in sewage, can inhibit the growth of harmful microorganisms and accelerate the decomposition of organic matters of residual feeds, animal and plant residual bodies and the like in water, and has a significant effect of water purification.

Description

technical field [0001] The invention relates to a composite microbial bacterial agent for sewage purification, in particular to a composite microbial bacterial agent for sewage purification and a preparation method thereof. Background technique [0002] With the development of the economy, water environment pollution has become one of the main factors restricting economic development and people's quality of life. Microbial agents play a very important role in the ecological restoration of the water environment and the purification of the water environment. The use of microbial agents to restore and purify polluted water rarely produces waste and discharges pollutants. This undoubtedly provides a good ecological treatment method for my country's increasingly polluted and deteriorating water environment, which has a broad market and application prospects. . Microbial ecological bacteria agent has good treatment ability for main pollution elements phosphorus, heavy metals and o...
