摘　　要：对粉煤灰吸附处理高浓度有机实验室废水的各种影响因素进行了研究。结果表明粉煤灰体系在最佳处理条件下:灰水比1:5,pH值为7,接触时间为60min,可使COD高达2944mg/L的实验室废水去除59.90%。用此法预处理有机高浓度实验室废水工艺简单,操作方便,成本低廉。The optium condition of fly ash treating high concentration organic wastewater in laboratory was researched. The experiment indicated that the removal of COD was as high as 59.90%,when pH was 7, stir time 60 minutes and proportion of fly ash to water 1:5. This kind of method have advantages of simple process, easy operation, and lower costs.
