| 摘 要： | 通过对拟建中的西安市第四污水处理厂初沉池入流污染物的沉淀试验，得到不同水深和沉淀时间下的ss去除率曲线。当有效水深为3．0m、沉淀时间为2h时，对SS、COD、TN和TP的平均去除率可分别达到63％、20．8％、7．0％和8．1％。试验结果对污水处理厂的设计具有重要的指导意义和实用价值。

| Abstract: | The settling test of influent sample was conducted in Xi'an No.4 Wastewater Treatment Plant under construction.The settling curve of SS is obtained under different water depths and retention time.The results show that removal rates are 63% for SS,20.8% for COD,7.0% for TN,and(8.1%) for TP at effective water depth of 3.0 m when the water retention time is 2 hours.The results have a directive and practical importance to the design of the wastewater treatment plant. |
