【摘要】 对风化煤吸附剂在常温下处理染料废水进行了实验研究 ,探讨了吸附时间、pH值和吸附剂用量对吸附效果的影响。结果表明 ,适量的吸附剂在pH值为 11.5时吸附 1d ,对废水的脱色率可达 99%左右 ,COD去除率在 95 %以上 ,BOD5可降低约 80 %。更多还原

【Abstract】 The experiment on treating dyeing wastewater with weathered coal showed that adsorption time,pH and the amount of weathered coal can affect the adsorption effect. The results indicated that the decolorization rate reached 99%, COD removal rate could surpass 95% and BOD₅ reduced about 80% when pH=11.5 and the time of adsorption is 1 day.更多还原
