摘　　要：在实验室采用自行设计的内循环三相生物流化床处理含氯漂白废水,经过40天左右的驯化,CODCr、BOD5去除率均达到70%以上,色度去除达约为70%,AOX去除率约为60%。后续进行絮凝处理,可以使该废水达到国家排放标准。另外还研究了水力停留时间,气体流量对流化床处理效果的影响。Chlorine bleaching effluent was treated with the Inner Loop Three Phase Fluidized Bed Bioreactor.The removal rates of COD Cr ,BOD 5 reached70%or more,the removal rates of chromaticity color and AOX reached70%and60%respectively after40days of domes-tication with the reactor.With the subsequent treatment of coagulation,the effluent could meet the discharge standard of the country.The influences of HRT and Qg to the character of fluidized bed bioreactor were also studied.
