摘要
研究了阳离子染料生产废水厌氧生物处理的可行性，结果表明在进水ＣＯＤ浓度２４００～４０００ｍｇ／Ｌ，色度７５００～１２５００倍，ＨＲＴ２．０ｄ下，反应器运行性能稳定，ＣＯＤ去除率可达到５０％～７０％，色度去除率９８％以上；同时出水的好氧生物降解性良好。经紫外—可见光吸收光谱分析揭示废水中有机物（ＣＯＤ）和色度的去除依赖于微生物的降解作用。
The feasibility of anaerobic biological process applied to treat cation dyestuff wastewater was examined The results found that the performance of anaerobic reactor was stable at the influent COD 2400～4000 mg/L, colority 7500～12 500 folds and HRT 2 0 d 50%～70% of COD and more than 98% of colority were removed It also showed that anaerobic effluent was biodegradable in sequential aerobic treatment The roles of microbial degradation for removing COD and decolorization were determined by analysising UV Visible absorable spectrum
