摘要
利用外置MBR用间歇射流曝气代替鼓风曝气;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1 987mg/L,NH3-N、TN(总氮)平均为100mg/L和114mg/L时,TP(总磷)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%.
Diry wastewater sewage was treated by an external MBR with jet-intermittent aeration instead of blast aeration.The ejector was installed on the suction pipe of the circulating pump.The results indicate that,the efficiency of optimized ejector is higher,the energy consumption is lower,When the average concentrations of CODCr,NH3N,TN and TP in feed water are 1 987 mg/L,100 mg/L,114 mg/L and 16.33 mg/L,respectively,that in effluent are 24 mg/L,15.8 mg/L,20 mg/L and 2.72 mg/L,and the removal rate of that are 98.67%,84.33%,82% and 83.37%,respectively.
