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 effect of integral membrane bioreactor (MBR) on the removal of major pollutants in aquaculture wastewater, the optimal operating parameters of integrated MBR for aquaculture wastewater were studied, and the operating parameters of HRT, aeration and MLSS were combined Design and investigate the effect of COD, NH3-N, NO-2-N, NO-3-N, TN, TP removal rate. The results showed that the influence degree of each operating parameter on effluent quality index was MLSS> HRT> aeration. According to the comprehensive balance method, the optimum operating parameters of the reactor are: HRT 3.25 h, aeration 375 L / h, MLSS 2.2 g / L.
