中文摘要:

      制浆造纸废水是一类成分复杂、难处理的高浓废水，探索、研究其深度处理技术十分迫切。本研究利用AB池、改良型卡鲁塞尔氧化沟和高效浅层气浮组合技术处理废水（废水的SS、COD_Cr和BOD₅分别为900～1100 mg/L、1200～1800 mg/L和600～900 mg/L）可使SS、COD_Cr、BOD₅的去除率分别达到97％、95％、97％，出水的SS、COD_Cr、BOD_{5,/sub>分别为30 mg/L、90 mg/L、20 mg/L，符合《造纸工业水污染物排放标准》（GB3544—2008）。}

Abstract:

      The pulping and papermaking wastewater has very complex composition with high COD，explore and study the techniques for this wastewater treatment are very urgent. The AB +modified carrousel oxidation ditch combined with efficient flotation has the advantages of higher load impact allowance, higher COD removal rate and lower energy consumption. By selecting rational technology parameters, AB+ modified carrousel oxidation ditch combined with efficient flotation can be used to treat pulping and papermaking wastewater with good result.
