摘　　要：为考察一体式膜生物反应器(一体式MBR)对养殖废水主要污染物去除效果的影响,研究一体式MBR处理水产养殖废水的最优操作参数,将操作参数HRT、曝气量、MLSS进行组合设计,考察其对COD、NH3-N、NO-2-N、NO-3-N、TN、TP去除率的影响。结果显示,各操作参数对出水水质指标的影响程度大小依次为MLSS>HRT>曝气量。根据综合平衡法,反应器最佳的操作参数组合为:HRT 3.25 h、曝气量375 L/h、MLSS2.2 g/L。In order to investigate the efficiency of integrated membrane bioreactor （ integrated MBR ） on major pollutants removal of aquaculture wastewater , the paper focused on the optimization of operational conditions for integrated MBR to treat aquaculture wastewater.The operating parameters of hydraulic retention time （HRT）, aeration rate and mixed liquid suspended solid （ MLSS） were designed to acquire its effect on COD , NH3 -N, NO2--N, NO3--N, TN and TP.The results showed that the influence degree of the parameters was MLSS 〉HRT〉aeration rate under this experimental conditions; the optimal operation parameters of the reactor were obtained as follows： HRT 3.25h, aeration rate 375L/h, MLSS 2.2 g/L.
