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COD_Cr为4000 mg/L、BOD₅为1350 mg/L、SS为2000 mg/L时，出水COD_Cr≤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。

Abstract:Pulping and papering wastewater 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 COD_Cr was 4000 mg/L, BOD₅ 1350 mg/L, SS 2000 mg/L, the effluent COD_Cr≤60 mg/L, BOD₅≤20 mg/L, SS≤30 mg/L, which are meet the emission limits of “the paper industry water pollution discharge standard”(GB3544—2008).
