长江中游不同类型城镇污水处理厂运行现状及新污染物赋存特征分析
Analysis on operation status and occurrence characteristics of emerging contaminants of different types of municipal wastewater treatment plants in middle reaches of Yangtze River
摘要
Abstract
In the new era,more complex water quality conditions(pathogens,emerging contaminants,etc.)and more stringent effluent standards have brought great challenges to the operation of wastewater treatment plants.Three wastewater treatment plants in middle reaches of the Yangtze River were selected according to inlet water quality characteristics.The operation of the three wastewater treatment plants in recent two years and the occurrence of emerging contaminants in the whole process of the wastewater treatment plants were systematically analyzed.The stability of the overall operation of wastewater treatment plants containing industrial wastewater is worse than that of wastewater treatment plants based on domestic sewage,especially in the removal of COD.The resulting increase in chemical and power consumption has doubled the treatment cost,and the selection of water plant operation equipment is too large,and long-term low-load operation will also bring about an increase in energy consumption.In terms of the occurrence of emerging contaminants,the overall concentration of perfluorinated and polyfluoroalkyl compounds in the water was low,the concentration of some antibiotics such as azithromycin was high,and the concentration of endocrine disruptors was lower than the detection limit.The existing process had a good effect on the removal of high concentrations of emerging pollutants but had a poor effect on the removal of low concentrations of emerging contaminants,and there was still a risk of release of emerging contaminants adsorbed by sludge.Strengthening the optimization of the existing water plant operating conditions and the monitoring and removal of emerging contaminants is the key to scientific and accurate pollution control of wastewater treatment in the new era.关键词
