摘要
某污水处理厂肩负着该市工业以及生活污水处理的重任,对某污水处理厂的水质指标进行监测,并对污染物的去除效果进行分析及评价.结果表明:某污水处理厂对污水进行处理后,pH为7.18～7.62;COD为10～27 mg/L,出口COD去除率为88%～95%;BOD5为1～7.5 mg/L,BOD5去除率为90%～97%;氨氮浓度为0.7～2.5 mg/L,NH3-N去除率为90%～97%;TN浓度范围10～13 mg/L,TN去除率为75%～80%;TP浓度为0.2～0.4 mg/L,TP去除率为83%～88%.通过与GB 18918-2002《城镇污水处理厂污染物排放标准》中一级B标准规定的最高允许排放浓度标准值比较,该污水处理厂各污染物浓度均达到标准要求,且处理效果比较稳定.
Abstract
A certain sewage treatment plant shoulders the heavy responsibility of industrial and domestic sewage treatment in the city.Therefore,this article monitors the water quality indicators of a certain sewage treatment plant,analyzes and evaluates the removal effect of pollutants by the plant.The results showed that a certain sewage treatment plant had a pH value between 7.18 and 7.62 after treating the sewage;The COD concentration is between 10～27 mg/L,and the removal rate of COD by the outlet is between 88%and 95%;The concentration of BOD5 is between 1～7.5 mg/L,and the removal rate of BOD5 is between 90%and 97%;The ammonia nitrogen concentration is between 0.7 and 2.5 mg/L,and the removal rate of NH3-N is between 90%and 97%;The concentration range of TN is between 10 mg/L and 13 mg/L,and the removal rate of TN is between 75%and 80%;The TP concentration is between 0.2 and 0.4 mg/L,and the removal rate of TP is between 83%and 88%.By comparing with the maximum allowable emission concentration standard value specified in the first Class B standard of GB 18918-2002"Pollutant Discharge Standards for Urban Sewage Treatment Plants",the concentration of all pollutants in the sewage treatment plant meets the standard requirements and the treatment effect is relatively stable.
