Study on Treatment of Chlorine Bleaching Effluent by Fluidized Bed Bioreactor - Coagulation Technology
tract: The Pulp chlorine effluent was treated by Inner - Loop Three - Phase Fluidized Bed Bioreactor.Afer 40 days of domestication in the reactor, the removal rate of cr and BOD5 could reach 70% or more, the temoval rates of chroma was 70% and AOX was 60%. Followed with the process of coagUlation, in which PFAC was used as nocculant and poIyacrylamide (PAM) as an assistant. The oudiow‘s c, was 80 mg/L, BOD was 20 mg/L, AOX < 1 mg/L and chroma was 120 C. U.
