摘要
Abstract
The stable and standard discharge of printing and dyeing wastewater after treatment is a key focus of environmental protection control for enterprises.A causal investigation scheme is established for the abnormal nitrogen indicators.The causes of abnormal nitrogen indicators are identified through traceability analysis of water quality indicators,process control,changes in microbial communities,and dye use.Due to changes in production discharge regulations,the use of acid dyes has increased rapidly.The chemical components of this type of dye have toxic and inhibitory effects on the growth of denitrifying bacteria,thereby reducing the efficiency of biochemical denitrification.Therefore,taking targeted measures in a timely manner,optimizing process regulation,and establishing an emergency linkage connection mechanism are beneficial to ensure stable and standardized water outflow.关键词
