| 摘 要： | 将膜生物反应器与脱氮除磷工艺相结合,建立水解酸化/好氧MBR中试装置,针对以精细化工废水和造纸废水为主的市政混合污水进行处理,系统考察了工艺的运行情况和处理效果.结果表明,在进水COD为335～941 mg/L、NH3-N为11.1～28.7 mg/L、TN为31.2～38.6mg/L、TP为1.0～17.4 mg/L的条件下,当系统水力停留时间约为48 h时,对COD、NH3-N、TN和TP的平均去除率分别为87.1%、91.0%、61.2%和93.7%.其中,出水NH3-N、TN和TP浓度均可达到GB 18918-2002的一级B标准;由于污水中难降解有机物的含量较高,导致出水COD浓度不能稳定达标,对此可在系统后设物化处理单元加以解决.
