Culture medium capable of improving biological stuffing microbial activity and preparation method thereof

Abstract

The invention provides a culture medium capable of improving biological stuffing microbial activity and a preparation method thereof, and relates to the technical field of biological stuffing. The culture medium is characterized by being prepared from, by weight, 100-150 parts of peptone, 80-100 parts of beef extract, 10-20 parts of yeast extract, 20-25 parts of glucose, 5-10 parts of sodium chloride, 20-30 parts of agar, 15-20 parts of bile salt from a pig, 12-18 parts of casein hydrolysate, 7-12 parts of sodium nitrate, 5-8 parts of monopotassium phosphate, 10-12 parts of amino acid and 16-20 parts of enrichment broth. The prepared culture medium allows growing microorganisms to be rich in type, a proper survival environment is provided for the microorganisms, nutritional ingredients (N, P, K and trace elements) are reasonable, the nutritional ingredients needed in the microorganism growth and reproduction processes are met, the microbial activity is greatly improved, the odor treatment effect is good, and the strictest environmental requirement in various regions can be met in any season.

Description

technical field [0001] The invention relates to the technical field of biological deodorization, in particular to a culture medium for improving microbial activity of biological fillers and a preparation method thereof. Background technique [0002] Biological deodorization is to use the action of microorganisms on the specific surface area of ​​the carrier filler to deodorize under suitable conditions. The odorous substances are first absorbed by the filler, and then oxidized and decomposed by the microorganisms attached to the filler, thus completing the deodorization process of the odor. In order to keep microorganisms highly active, a good living environment must be created for them. For example: suitable humidity, pH value, oxygen content, temperature and nutrient content, etc. The actual production design requires that the relative humidity of the carrier filler is kept at 80-95%, so the raw sewage or primary sedimentation tank effluent is often used to provide water...

AI Technical Summary

Problems solved by technology

However, this method cannot provide enough nutrients for the attached microorganisms, and the activity of microorganisms cannot be maximized, so that the deodorization effect is poor and cannot meet the expected requirements.
