Enhanced CFBR process applied to treatment of wig wastewater containing high ammonia nitrogen

Abstract

The invention discloses an enhanced CFBR process applied to treatment of wig wastewater containing high ammonia nitrogen. The method comprises the steps: performing amplification culture on Thauera sp. FDN-01 and Paracoccus sp. FDN-02 strains to prepare a high-efficiency denitrification engineering bacterial agent, respectively adding the high-efficiency denitrification engineering bacterial agent into an anoxic tank and a hypoxic tank of a CFBR treatment device, and intensively removing high-concentration ammonia nitrogen and total nitrogen in the wig wastewater under the action of various denitrification functional enzymes. The process disclosed by the invention is applied to treatment of high-concentration ammonia nitrogen in the actual wig wastewater, the effluent quality stably reaches and is far lower than the A-level limit value of 'Water quality standard for sewage discharged into urban sewers' (GB / T 31962-2015) under the condition of normal temperature, and the removal rate of ammonia nitrogen and total nitrogen in the wig wastewater is high. The method is free of secondary pollution to the environment and low in treatment cost and energy consumption.

Description

technical field

[0001] The invention belongs to the technical field of industrial wastewater treatment, and in particular relates to an enhanced CFBR process applied to the treatment of wig wastewater containing high ammonia nitrogen. Background technique

[0002] In recent years, with the rapid economic development and the improvement of people's living standards, wearing wigs has gradually become a fashion. However, a large amount of industrial wastewater containing high ammonia nitrogen will be discharged during the wig production process. If it is discharged directly without any treatment, it will cause serious pollution to the water environment. At present, the methods for denitrification of industrial wastewater include physical methods, chemical methods and biological treatment methods. Biological treatment has gained widespread attention due to its low investment, simple operation, low secondary pollution, and low operating costs.
