Abstract

The invention relates to the field of sewage treatment and in particular discloses a microorganism compound bacterium agent for treating alkaline printing and dyeing wastewater. The microorganism compound bacterium agent is prepared from the following bacterium liquid in percentage by mass: 10 to 16 percent of bacillus subtilis bacterium liquid, 10 to 16 percent of pseudomonas aeruginosa bacteriumliquid, 10 to 16 percent of pseudomonas stutzeri bacterium liquid, 5 to 15 percent of rhodococcus bacterium liquid, 5 to 15 percent of micrococcus luteus bacterium liquid, 5 to 15 percent of alcaligenes faecalis bacterium liquid, 3 to 8 percent of bacillus cereus bacterium liquid, 3 to 8 percent of bacillus stearothermophilus bacterium liquid, 3 to 8 percent of bacillus licheniformis bacterium liquid, 3 to 8 percent of acinetobacter baumannii bacterium liquid, 3 to 8 percent of saccharomycetes bacterium liquid and 3 to 8 percent of white rot fungus bacterium liquid. A preparation method of the compound bacterium agent comprises the following steps of: activating raw strains, carrying out amplified culture and preparing the compound bacterium agent. The problems in the prior art that the cost is high and the secondary pollution is serious when chemicals are used for treating the alkaline printing and dyeing wastewater are solved.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a microbial composite bacterial agent for alkaline printing and dyeing wastewater treatment. Background technique [0002] In recent years, with the technological progress and continuous innovation of the textile printing and dyeing industry, the use of chemically synthesized raw materials (dyes and auxiliaries) has greatly increased, making the quality of printing and dyeing wastewater more complex. The discharged printing and dyeing wastewater contains a large amount of slurry, dyes, auxiliaries and surfactants. Alkaline printing and dyeing wastewater generally has the characteristics of high CODcr (chemical oxygen demand), high SS (suspended solid particles), high chroma, high alkalinity, high pH and high salinity, and the discharge volume is large, and organic pollutants Large changes, large fluctuations in water quality, and high toxicity have increased the difficulty of ind...
