利用外置MBR对乳品废水进行试验研究，采用间歇射流曝气代替鼓风曝气；改变射流器安装方式，射流器安装在循环加压泵吸水管上。结果表明，经优化的射流器安装方式与普通安装方式相比能耗更低、充氧效率更高。进水CODcr平均为1987mg/L，NH3-N、TN 平均为100mg/L和114mg/L时，TP平均为16.33mg/L；出水CODcr平均为24mg/L，去除率为98.67%；出水NH3-N、TN平均为15.8mg/L和20mg/L，去除率分别为84.33%和82%；出水TP平均为2.72mg/L，去除率83.37%。

Use external MBR deal with dairy wastewater sewage,change the way of ejector installation method, ejector was set up on the incurrent canals of Circulating Pump; The results indicated that, Optimize Ejector is higher in efficiency, lower in energy consumption, Into the water for CODcr averages 1987mg/L, NH3-N、TN averages 100mg/L and 114mg/L, TP averages 16.33mg/L, effluent CODcr 24mg/L, the averages removal rate is 98.67%；NH3-N、TN15.8mg/L and 20mg/L，the removal rate is 84.33% and 82%; TP2.72mg/L, the removal rate is 83.37%.
