Method for treating sulfanilamide pharmaceutical wastewater by compound microbial preparation

Abstract

The invention discloses a method for treating sulfanilamide pharmaceutical wastewater by compound microbial preparation. The method comprises the following steps: putting a compound microbial preparation into a biochemical tank, wherein the initial concentration of the compound microbial preparation is 0.02-0.05% of the volume of the biochemical tank. The method for treating sulfanilamide pharmaceutical wastewater by compound microbial preparation has the following beneficial effects: the compound microbial preparation is directly put into the biochemical tank so as to improve the treatment effects by the highly effective degradation characteristics of the microorganisms, so that the treatment difficulty is reduced; moreover, the method is low in cost, and is capable of realizing effective eliminations and reductions of pollutants in the wastewater, including COD, ammonia nitrogen, aniline, volatile phenol and the like.

Description

technical field [0001] The invention relates to the technical field of bioengineering, in particular to a method for treating sulfonamide pharmaceutical wastewater by using a compound microbial preparation. Background technique [0002] Sulfonamide drugs are the earliest synthetic antibacterial drugs, which have the advantages of broad antibacterial spectrum, strong curative effect, convenience and safety. It mainly treats diseases caused by various bacterial infections, and is also widely used in aquaculture. As an important chemical and pharmaceutical raw material, sulfadiene is an important chemical and pharmaceutical raw material. The wastewater discharged during the production process mainly comes from the sulfadiene acid, ammonification, and hydrolysis sections. It has the characteristics of high salinity, high concentration of organic matter, and has certain toxicity to microorganisms. [0003] With the rapid development of my country's pharmaceutical industry, the p...

Problems solved by technology

Due to the different production processes of different drug varieties in the production process of sulfonamide drugs and the short product replacement cycle, the pharmaceutical wastewater often contains a wide variety of organic pollutants, and there are large differences in water quality and water volume. Once the product is replaced, its wastewater The water quality and quantity are often fluctuating and extremely unstable. It contains many pollutants that are difficult to degrade or inhibit microorganisms, which increases the difficulty of water treatment.

In addition, in the continuous expansion of production, many original sewage treatment facilities can no longer meet the increasing amount of wastewater. How to improve the treatment effect on the basis of effective control of economic costs is the focus of attention at present.
