Embodiment Construction

[0010] The present invention will be further described below in conjunction with embodiment.

[0011] This example proceeds as follows.

[0012] The wastewater is from a pharmaceutical factory, which mainly produces sulfamethazine and sulfamethoxazole. Wastewater enters the biochemical system after physical and chemical treatment, and the water quality indicators entering the biochemical system are as follows:

[0013] CODcr: 2000~4000mg / l

[0014] Ammonia nitrogen: 200~300mg / l

[0015] SS: 150~250mg / l

[0016] Chromaticity: 100 dilution times

[0017] Aniline: 10-20mg / l

[0018] Volatile phenol: 5mg / l

[0019] Dosing amount of compound microbial preparation: 0.2-0.5% of the volume of the biochemical pool.

[0020] Add the compound microbial preparation whose initial concentration is 0.2-0.5‰ of the treatment volume of the biochemical pool into the biochemical pool.

[0021] Preparation of compound microbial preparations: screening and separating the biochemical pool s...

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...
