Fermenting technology of compound bacterial agent for treatment of riverway sewage

Abstract

The invention discloses a fermenting technology of a compound bacterial agent for treatment of riverway sewage. The fermenting technology comprises nitrification bacteria, denitrification bacteria, photosynthetic bacteria, bacillus subtilis, amino acid enzyme microorganism and the like. The fermenting technology is characterized by comprising the following steps of S1, preparing of a culture medium; S2, anaerobic fermenting; S3, air ventilating fermenting; S4, domesticating fermenting; S5, preparing of the compound bacterial agent for the treatment of the riverway sewage. The fermenting technology has the advantages that by adopting the nanometer soybean powder, the nutritional value is high; by adopting trace elements, the biological activity is fully maintained, and the nutrient diversity of the substrate is enhanced; by adding straw powder, the content of cellulose is increased, and the nutritional components of the substrate are comprehensive, and are suitable for the growth of probiotics; by adopting multiple cycles of sewage and temperature domesticating propagation, the survival rate and content of flora in the bacterial agent are high, and the biological activity and suitability are strong; the efficiency is high, the stability is realized, and the propagation is quick; the harmful matters of ammonia nitrogen and the like in the water body are degraded, the bacteria phase in the water body is quickly restored and balanced, the water body is purified, and the environment is improved; the defects in the prior art are overcome.

Description

technical field [0001] The invention relates to the technical field of biological bacterial agents, in particular to a fermentation process of a composite bacterial agent for river sewage treatment. Background technique [0002] The compound microbial agent for river sewage treatment in the prior art is prepared by a conventional fermentation process, which has poor controllability in the fermentation process, low survival rate and content of beneficial bacteria, and poor biological activity and adaptability. [0003] The present invention adopts soybean powder with broken cell wall to have high nutritional value, and the nano-fine crushing of broken cell wall can fully maintain the biological activity of trace elements in the raw material, enhance the nutritional diversity of the matrix, add straw powder to increase the cellulose content, and increase the nutritional value of the matrix. The ingredients are comprehensive and conducive to the growth of probiotics. Multiple ...
