摘　　要：采用中试规模的CASS系统和混凝工艺处理粘胶纤维混合废水,重点研究了有机负荷、周期时间、混凝剂种类及投加量对处理效率的影响。结果表明,该工艺对CODCr、BOD5、色度的去除率分别达到95%、96%和95%,出水中S2-和锌离子也分别低于1mgL和2mgL,出水水质达到了(GB89781996)的一级排放标准。Mixed wastewater of viscose fiber is treated with cyclic activated sludge system and coagulation; the influences of organic load, periods, the types and dose of coagulant on the removal efficiency are investigated.The results show that the removal efficiency of COD_ Cr,BOD_5, chroma can reach 95%,96%,95% respectively, and the effluent can meet the first-order of “The National Wastewater Discharge Standard”(GB8978-1996).
