新疆某污水厂冬季出水总氮及氨氮超标的优化调控
Optimization and Regulation of Total Nitrogen and Ammonia Nitrogen Excessive Discharge in Winter of a WWTP Effluent in Xinjiang
摘要
Abstract
The effluent ammonia nitrogen and TN from a wastewater treatment plant(WWTP)in Xinjiang exceeds the standard in winter.The online data and the tracking analysis of related indicators showed that:due to the increase of the proportion of industrial wastewater,the nitrogen of influent exceeded the standard.Coupled with the low temperature,the microbial activity decreases and the biological nitrogen removal function was inhibited,which was the main reason for the ammonia nitrogen and TN of effluent exceeding the standard.In addition,incomplete ammoniation reaction and low removal rate of ammonia nitrogen conversion in hydrolytic acidification pool were also important reasons for excessive TN and ammonia nitrogen.The paper analyzed the corresponding problems and put forward the optimization and improvement measures.The average values of ammonia nitrogen and TN in the effluent after optimization and adjustment are 5.47 mg/L and 11.92 mg/L respectively,which meet the emission standard and do not exceed the standard.关键词
