| 中文摘要 |
| 絮凝、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研究表明，在水力停留时间为１５ｈ 时，ＣＯＤ总去除率达８３．９％ ，毒性去除率９２％ ． ＧＣ－ＭＳ、超滤实验结果表明：原废水污染物是以氯代酚为主的氯代有机物，其中毒性物质主要来源于相对分子质量小于１０００的低分子物质． 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，低分子量的酸性组分和烷烃类明显增加，表明污染物得到了进一步的氧化降解． |
| 英文摘要 |
| The flocculation anaerobic acidification aerobic reactor was investigated for the treatment of pulp CEH bleaching effluents,and the removal of COD and toxicity were 83.9%、92% respectively with 15h retention time.The results of GC MS and superfiltration showed that pollutants of wastewater were mainly chlorinated organisms chlorophenol and the toxicity came from low molecule weight substances;the removal in the floc unit was mainly high molecule weight chlorinated compound;most of chlorinated compounds were removed by reduced dechlorination and acidified hydrolysis in anaerobic unit;the high COD removal in aerobic unit with significantly increasing of acid substance and alkyl showed further degradation of pollutants. |
