Dominant consortium flora for degrading urban waste water and preparation method thereof

Abstract

The invention discloses a dominant consortium flora for degrading urban waste water and a preparation method thereof. The preparation method comprises the following steps of: inoculating and culturing enterobactercloacae, gordonia and pseudomonasputida respectively; mixing 20-24 percent by volume of enterobactercloacae, 54-58 percent by volume of gordonia and 26-18 percent by volume of pseudomonasputida respectively; and preparing calcium alginate immobilized particles, activating, and directly putting into urban waste water. By coordinating among strains, the TOC (Total Organic Carbon) degrading efficiency of urban waste water by microbial treatment can be increased effectively.

Description

technical field

[0001] The invention relates to the field of urban wastewater treatment, in particular to a dominant bacterial group for degrading urban wastewater and a preparation method thereof. Background technique

[0002] Biological treatment is a commonly used wastewater treatment method at present. This method decomposes and absorbs the pollutants in wastewater through the metabolism of microorganisms, so as to achieve the purpose of pollution control. Compared with other methods, biological treatment has low cost, high efficiency, easy operation, and most importantly, no secondary pollution. Therefore, it has been widely used in the treatment of urban sewage and industrial sewage. With the development of the economy, the composition of wastewater is becoming more and more complex, especially when the wastewater contains toxic and refractory organic pollutants, due to the small number and types of microorganisms with special degradation ability for this type of organ...
