Embodiment Construction

[0009] The preparation method of the microbial flora for treating printing and dyeing wastewater is:

[0010] (1) Collection of engineering original flora

[0011] After long-term work practice and scientific experiments, it is found that there are a large number of beneficial microbial strain resources near the pollution source. They can adapt to the pollutant and undertake the main responsibility of degrading the pollutant and purifying the environment. Therefore, the bacterial population is collected from the vicinity of the pollution source. It is one of the main means to obtain the flora that can efficiently degrade the pollutant, see references (edited by Shen Dezhong, Bioremediation of Polluted Environment, Chemical Industry Press, Beijing, 2001, 163-174). The invention collects and obtains the engineering original flora from the sewage and silt at the sewage outlets of four printing and dyeing factories in Shaoxing Printing and Dyeing Industrial Park. The collection o...

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...
