Process for preparing microorganism species for treating dyeing waste water

Abstract

The invention disclosed a preparing process of microbial population which can be used to treat dying waste liquids. Collect the engineering primitive microbial population from the sewage or silt on the discharging point of the dying factory. Enrich the microbe by inoculating the primitive microbial population on the medium for 5-7d to get the engineering microbial population. Add 5%, 10%, 15%, 20% and 25% dying waste liquids to the microbe medium and habituated cultivate the microbe according to the microbe's cultivating method for 7-10d to get habituated microbial population. The invention has many advantages such as economical, efficient, safe, great adaptivity and no secondary pollution, so it's an ideal microbial population to treat dying waste liquids.

Description

technical field [0001] The invention relates to a preparation method of microbial flora for treating printing and dyeing wastewater, which is suitable for the treatment of wastewater discharged from printing and dyeing factories. Background technique [0002] With the development of dye and printing and dyeing industry, the wastewater produced by it has become one of the most important sources of water pollution. The composition of printing and dyeing wastewater is very complex. The choice of dye raw materials is different, and the composition of wastewater is also different. Generally speaking, the main components of printing and dyeing wastewater are azo dyes, anthraquinone dyes, and a mixture of compounds such as aniline, nitrobenzene, and phenols. , Sichuan Silk, 2002(3), 15-17.). Printing and dyeing wastewater not only has a visual impact on the environment, but also is mostly toxic and refractory organic matter, which has strong chemical stability, carcinogenic, tera...

AI Technical Summary

Problems solved by technology

Physical and chemical methods have problems such as high operating costs and secondary pollution

In the conventional biological treatment process, due to the complex structure and toxicity of the degradation objects, the metabolism of conventional microorganisms is greatly inhibited. The degradation effect of aerobic bacteria on refractory organic matter is very limited. Although anaerobic bacteria are effective in degrading some organic matter, they are There is a risk of generating more toxic amine organic compounds, and aniline is difficult to further degrade

Therefore, the microorganisms cultivated by conventional methods are not ideal for the treatment of printing and dyeing wastewater.
