摘要
利用由磷酸-微波法处理剩余活性污泥制得吸附剂,研究了它对三硝基甲苯红水的吸附性能,考察了废水pH值、吸附时间、吸附剂投加量对吸附效果的影响,实验结果表明,该吸附剂2个最佳pH值范围为4左右和9左右,吸附平衡时间为60min;当吸附剂的投加量为8%时,其CODCr去除率达到了85.7%。
Adsorbent was derived from the treatment of excess activated sludge by phosphoric acid-microwave method, the adsorption performance of it on trinitrotoluene red water was studied, and the effects of the pH value, adsorption time, dosage of adsorbent on the result of adsorption were investigated, the results of the test show that: the two optimal pH ranges for the said adsorbent are about 4 and about 9, the balance time of adsorption is 60 min; when the dosage of the adsorbent is 8%, the removal rate of CODCr reaches 85.7%.
