摘要
以贵州某污水处理厂排污口污水作为分析对象,分别采集两批排放污水,采用AFS、AAS、可见分光光度法、重量法等方法对排出污水中的城镇污水处理厂水污染物排放基本控制项目进行相关性分析,并以单因子指数法和内梅罗综合指数法对其进行评价。结果表明,虽然整体水质较好,但仍有粪大肠菌群和总铬未能满足排放标准,其中粪大肠菌群污染最为严重,对于人体和环境具有一定的危害。
Taking the sewage from the sewage outlet of a sewage treatment plant in Guizhou as the analysis object,two batches of sewage were collected at the sewage outlet.The AFS,AAS,visible spectrophotometry and weight method were used to analyze the correlation of the basic control projects of water pollutant discharge in urban sewage treatment plants,and the single factor index method and Nemero comprehensive index method were used to evaluate it.The results showed that although the overall water quality was good,fecal coliforms and total chromium still failed to meet the emission standards,and fecal coliforms pollution was the most serious,which had certain harm to human body and the environment.
