摘要
介绍了采用A^2/O生化法+物化法工艺的污水处理厂的工艺流程、主要构筑物参数,对COD、TP、TN、NH3-N等测定数据进行分析,评价污水处理厂运行效果。结果表明,污水经过处理后,COD、TP、TN、NH3-N平均去除率分别达到88.9%、89.0%、49.7%、98.4%,出水COD为17 mg/L,TP、TN、NH3-N的质量浓度分别为0.145、9.15、0.23 mg/L,满足GB 18918-2002的一级A标准要求。在进水COD低于设计条件的情况下,出水污染物含量不易受进水量增加的影响。
The technological process and main structures parameters of sewage treatment plant with A^2/O biochemical and physiochemical process were introduced. The operation effect of sewage treatment plant was evaluated by analyzing the data of COD, TP, TN and NH3-N. The results showed that the average removal rates of COD, TP, TN and NH3-N were 91.5%, 94.6%, 49.4% and 98.4% respectively after the sewage treatment. The COD, mass concentration of TP, TN and NH3-N in effluent were 17 mg/L, 0.145, 9.15 and 0.23 mg/L respectively, which reached the first level A standard of GB18918-2002. Under the condition of the influent COD was lower than the designed condition, the effluent pollutant content was not easy to be affected by the increase of influent volume.
