| 摘 要： | 本文研究了混凝，厌氧酸化，生物接触氧化一体化反应器处理造纸制浆含氯漂白废水，在水力停留时间为15h时，整个系数CODcr总去除率达88．1％，BOD5去除率达81％，AOX去除率达98．4％，毒性值去除了92％，絮凝单元去除的主要是大分子氯代有机物，厌氧单元通过还原脱氯及酸性水解，氯代有机物得到了基本的去除；好氧单元对COD有较高的去除率，红外光谱的分析结果表明：废水中既有木素又有纤维素和半纤维素，虽然漂白废水厌氧处理效果不如好氧处理，但厌氧，好氧联合处理可有效地提高其处理效果。

| Abstract: | The coagulation_anaerobic acidification_aerobic reactor was investigated for the treatment of pulp CEH bleaching effluents, and the removal efficiency of COD?BOD 5?AOX and toxicity were 88.1 %?81%?98.4% and 92% respectively with 15h retention time. What was removal in the floc_unit was mainly high molecule weight chlorinated compound; Most of the chlorinated compounds were removed by reduced dechlorination and acidified hydrolysis in the anaerobic unit. The high COD removal was found in the aerobic unit. FTIR results showed that there were ligns,cellulose,hemicellulose in effluents. The combination of anaerobic and aerobic process could effectively improve the CODcr removal rate. |
