摘要
北方某城市污水处理厂采用A2/O—MBR组合工艺,对污水处理厂半年内的实际运行数据进行分析,研究了主要运行参数对工艺的影响以及组合工艺对各种污染物的去除效果,可得系统出水CODCr、NH3—N、TP分别为30 mg/L1、mg/L、0.37 mg/L,去除率分别为90%、94%、91%,出水水质达到《城市污水再生利用城市杂用水水质》(GB/T 18920—2002)要求,系统运行稳定,并具有较强的耐冲击负荷能力。
A municipal wastewater treatment plant in north China employed A2/O-MBR process.Based on the analysis of practical operation data in half year,the effects on process from main operation parameters and the effects on pollutant removal from combination process were studied.The results showed： the CODCr,NH3-N,and TP in effluent were 30 mg/L,1 mg/L and 0.37 mg/L,the removal rates were 90%,94% and 91% respectively,and the effluent quality could meet The reuse of urban recycling water-Water quality standard for urban miscellaneous water consumption（GB/T 18920—2002）.The whole system was stable and has strong resist impact load capability.
