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

Pulping and Papermaking Wastewater Treatment by Using IC-modified Oxidation Ditch Process

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 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 CODCr was 4000 mg/L, BOD5 1350 mg/L, SS 2000 mg/L, the effluent CODCr ≤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＂ （ GB354d-2008 ）.
