摘　　要：以广州市猎德污水处理厂二期工程UNITANK工艺为例,研究分析了近三年来的运行效果。UNITANK工艺应用于城市污水处理具有良好的运行效果:COD、BOD5去除率稳定在88%以上;在没有内回流的情况下TN去除率在40%～60%之间;增加以液态硫酸铝为投加剂的化学除磷设备后,TP去除率稳定在86%以上,各项出水指标均在排放限值以下,达到国家《城镇污水处理厂污染物排放标准》(GB18918-2002)一级B标准。UNITANK工艺在进水浓度较低的大型城市污水处理厂的应用是可行的。Operation effect of UNITANK process which was used in Phase II of Liede Wastewater Treatment Plant, Guangzhou wasanalyzed. Results showed that the running effect was quite good, with removal efficiency of BOD5 and COD over 88%, removal efficiency of TN between 40%-60% without internal recycle and removal efficiency of TP over 86% with supplement of chemical phosphorus removal using liquid aluminum sulfate as chemical agent. Final effluent quality well met Grade I standard of GB18918-2002. UNITANK process is feasible to be applied in large scale urban wastewater treatment plant with low influent concentration.
