IC厌氧反应器-改良型氧化沟-浅层气浮工艺处理制浆造纸废水

摘要

采用IC厌氧反应器-改良型氧化沟-浅层气浮工艺处理制浆造纸废水,介绍和分析了整个工艺的主要构筑物及其调试运行方法.当进水CODCr为4000 mg/L、BOD5为1350 mg/L、SS为2000mg/L时,出水CODCr,≤60 mg/L、BOD5≤20 mg/L、SS≤30 mg/L,达到GB3544-2008造纸工业水污染物排放标准的污染物排放限值.%Pulping and papering waatewater was treated by using IC anaerobic reactor-modified oxidation ditch-shallow air-floatation system, the main construction and commissioning method of the whole system were introduced and analyzed. When the influent CODCr was 4000 mg/L, BOD5 1350 mg/L, SS 2000 mg/L, the effluent CODCr≤60 mg/L, BOD, ≤20 mg/L, SS≤30 mg/L, which are meet the emission limits of "the paper industry water pollution discharge standard"(GB3544-2008).
