| 摘 要： | 研究了以混凝、厌氧酸化、生物接触氧化一体化反应器处理含氯漂折护望洋兴叹，水力停留时间为15h时，整个系统CODCr、BOD5、AOX、毒性值去除率分别达88.1%、81%、98.4%、92%。混凝单元主要去除大分子氯代有机物；厌氧单元通过还原脱氯及酸性水解，使氯代有机物得到了基本的去除；好氧单元对CODCr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技术不如好氧处理，但厌氧、好氧联合处理可有效地提高处理效果。

| Abstract: | The coagulation-anaerobic acidification-aerobic reactor was studied for the treatment of CEH bleaching effluents,and the removal efficiencies of COD Cr ,BOD 5 ,AOX and toxicity were88.1%,81%,98.4%and92%respectively with15h retention time.The removal in the floc-unit was mainly high molecule weight chlorinated compound;Most of chlorinated compounds were removed by reduced dechlorina-tion and acidified hydrolysis in anaerobic unit;The higher removal efficiency of COD Cr was found in aerobic unit.FTIR results indicated that there were lignin,cellulose and hemicellulose in the effluents.The combination of anaerobic and aerobic process could effectively im-prove the COD Cr removal rate. |
