Abstract

The invention discloses a preparation method of a microbial sewage purification treatment agent, and belongs to the technical field of wastewater treatment. According to the invention, a culture medium containing a bacillus natto liquid is prepared from soybean milk, wherein gamma-polyglutamic acid is rich, the gamma-polyglutamic acid can be complexed with metal salt ions in water pollutants to obtain gamma-polyglutamate, the adsorbent has the advantages of biodegradability, good biocompatibility, high water-retaining property and the like, the polypeptide structure of the gamma-polyglutamic acid and carboxyl and amino groups rich in a molecular chain are extremely similar to physiological properties of microorganisms, the gamma-polyglutamic acid is extremely easy to coexist with microorganisms, a space reserved after the gamma-polyglutamic acid is biologically degraded provides a space for subsequent microorganism growth, and the quantity of active microorganisms on the adsorbent is increased, so that the biofilm culturing quantity of the adsorbent microorganisms is increased, and the application prospect is wide.

Description

technical field [0001] The invention discloses a preparation method of a microbial sewage purification treatment agent, which belongs to the technical field of waste water treatment. Background technique [0002] With the development of the economy, there are more and more chemical plants in various places, and the treatment of industrial sewage has become a hot spot of concern from all walks of life. The discharge of traditional electroplating, tanning, metal surface treatment, printing and dyeing, petrochemical and other organic pollutants is increasing. Increase. [0003] Organic wastewater is wastewater mainly composed of organic pollutants. Organic wastewater is likely to cause eutrophication of water quality and is relatively harmful. Organic wastewater generally refers to the wastewater discharged from printing and dyeing, papermaking, leather and food industries with a concentration of more than 2000mg / L. Industrial wastewater such as textile printing and dyeing, d...
