Problems solved by technology

However, in the process of treating industrial wastewater with ozone oxidation technology, there are still some deficiencies, specifically: (1) Ozone utilization rate is not high due to reasons such as ozone self-decomposition and dissolution utilization rate; (2) The selectivity of ozone oxidation is relatively low. Strong, its removal rate of refractory organic matter is low, it needs to use a catalyst, resulting in a large dosage of ozone oxidation, which increases the operating cost

Abstract

The invention relates to a compound bacterium colony for de-coloring papermaking industrial wastewater and a preparation method thereof. The compound bacterium colony is prepared from 2 to 10 parts of amycolata bacillus, 10 to 20 parts of curtobacterium flaccumfaciens, 20 to 30 parts of white rot fungi, 10 to 15 parts of pseudomonas putida, 20 to 30 parts of agrobacterium, 10 to 30 parts of pseudomonas stutzeri and 20 to 30 parts of enterobacter cloacae. According to the compound bacterium colon provided by the invention, microorganisms have a beneficial mutual effect and the microorganisms are mixed, cultured and domesticated; certain improvement is carried out on a flowing direction of intermediate metabolites of pollutants by bacteria and inhibitive intermediate metabolites are not generated or are transformed as soon as possible, so that the degradation efficiency of the pollutants is improved.

Description

technical field [0001] The invention relates to the field of papermaking wastewater treatment, in particular to a composite bacterial group for decolorizing papermaking industrial wastewater and a preparation method thereof. Background technique [0002] The water consumption situation of my country's paper industry is still high consumption, low efficiency, heavy pollution, which is extremely incompatible with my country's water resource conditions, and it is also one of the severe challenges that the paper industry is currently facing. After adopting technologies such as alkali recovery and biological treatment, one of the keys that affect papermaking wastewater to meet new discharge standards or reuse is the problem of chromaticity. [0003] Because the main component that causes the chromaticity of papermaking wastewater is lignin-based chromogenic substances, which have good chemical stability and are difficult to remove. The traditional methods mostly use strong oxidi...
