摘要
通过正交实验研究改性膨润土吸附处理模拟含氟废水。结果表明:改性膨润土用量为4g;吸附平衡时间30min;废水pH=4,出水含氟量由100mg/L降至1.9mg/L,去除率可达98.1%,达到国家含氟废水一级排放标准。该工艺具有处理效果好,操作简单等优点。
A simulating test on treatment of fluoride-containing wastewater with modified bentonite adsorption is conducted by the orthogonal test method.The results showed that under following optimal technological conditions：the dosage of modified fly ash is 4g,contact time 30min,pH value 4,the removal rate of fluoride can reach 98.1%,the concentration of fluoride in the treated wastewater is reduced from 100 to 1.9mg·L-1,which is up to the first-class national standards.The technology has advantages of high treatment efficiency,easy to operate and so on.
