Description

Technical Field

[0002] At present, when treating sewage with a traditional biochemical system, when the system is impacted or the treatment efficiency of the system operation decreases, it is necessary to supplement microbial agents and nutrients to quickly restore the treatment capacity. At present, the methods of adding microbial agents are usually divided into adding liquid bacterial agents and dry powder bacterial agents. In order to quickly reach the population density of microorganisms, a large amount needs to be added.

[0003] Due to storage condition limitations, the effective viable bacteria count and the bioenzymes produced by fermentation of liquid bacterial agents decay significantly in a short period of time. When adding, the population density and enzyme activity are greatly reduced, affecting the use effect of the product; after the production of dry powder bacterial agents, in order to preserve the product for a long time, it is necessary to add stabilizers and reduce the moisture content of the product, so that the microbial cells are in a dormant state, and the bioenzyme activity produced during the fermentation process is basically lost. It takes a long time to colonize after being put into the biochemical system before it can take effect, and the efficacy is greatly reduced. Therefore, designing a dry powder bacterial agent activation and expansion culture device that can improve the addition efficiency after strain activation is an urgent problem to be solved in the current industry.
