摘　　要： 试验采用Al2(SO4)3、碱式氯化铝、FeCl3、复合脱色剂、阳离子聚丙烯酰胺和粉末活性炭等混凝剂、助凝剂、吸附剂对甘蔗糖蜜酒精废水厌氧-好氧处理尾水进行了后处理研究.结果表明:采用10%FeCl3溶液和粉末活性炭处理该尾水,色度和COD一般分别可降到30倍与300mg/L以下,达到酒精行业废水排放二级标准.Al2(SO4)3、碱式氯化铝和复合脱色剂均对该尾水色度有良好的去除效果,去除率可达70%以上,但COD去除率小于65%,后处理出水难以达标. An experiment is introduced, in which coagulating agent、coagulant aids and adsorbent are used along with aluminum chloride,iron(Ⅲ) chloride,compound decolorant,polyacrylamide and powdered carbon to treat sugarcane molasses wastewater after anaerobic-aerobic process.It is shown that colority and chemical oxygen demand of the wastewater can be decreased to thirty times and less than 300 mg/L respectively by 10% iron(Ⅲ) chloride liquor and powdered carbon.It is expected to meet the second class discharge standard of alcohol industry. The removal efficiency of wastewater will reach more than 70% with aluminum sulfate,aluminum chloride and compound decolorant. But the removal efficiency of chemical oxygen demand is generally lower than 65% and the effluent fails to meet the national discharge criteria.
