Abstract

The invention belongs to the technical field of biology and water treatment, and provides a preparation method and application of a semi-dry state nitrifying bacterial agent. (2) After enrichment culture, carry out domestication culture to obtain a culture solution with high nitrification activity; (3) Concentrate the culture solution and place it at a certain concentration (4) Mix (3) the mixed solution with the treated carrier to obtain a bacterial agent; (5) put the bacterial agent into a vacuum-sealed bag, vacuum seal, and place it in a cool place Store at room temperature. The bacterial agent only needs to be dispersed with water, and then added to the aerobic biochemical system. It has the characteristics of high activity, high tolerance, good stability, strong resistance to stress, etc., and is convenient for transportation and storage. , small footprint and other advantages; no activation and rejuvenation are required during application.

Description

technical field

[0001] The invention belongs to the technical field of biology and water treatment, and provides a preparation method and application of a semi-dry nitrifying bacterial agent. Background technique

[0002] Ammonia nitrogen has become one of the common pollutants in the water environment, which endangers the safety of aquatic organisms and even the entire ecosystem. There are physical, chemical and biological methods for denitrification. Biological methods are widely used in sewage treatment due to their advantages of simple operation, low investment, low cost, no secondary pollution and good treatment effect. Nitrifying bacteria are the main microorganisms in the process of biological denitrification, and the stability of nitrification and the improvement of nitrification rate are the keys to affect the denitrification efficiency of the whole system. Nitrifying bacteria are strictly aerobic and autotrophic bacteria with harsh living conditions and slow growt...
