摘要
用Fenton试剂结合自制聚硅硫酸铝对焦化废水进行了催化氧化—混凝试验研究 ,选择了最佳的工作条件。结果表明 ,经氧化—混凝处理后废水的COD从 1 1 73mg/L降至 38.2mg/L ,去除率达 96 .7%。研究中还发现 ,Fenton试剂具有将废水的 pH值调节为 2 .5～ 3的特性 。
Fenton reagent and a coagulant PASS (polymeric aluminum silicate sulfate) were both self-prepared in laboratory and used to treat coke plant wastewater in a bench-scale experiment. The results showed an excellent reduction of COD: from 1173 mg/L to 38.2 mg/L. It was also found the specificity of Fenton reagent to adjust pH values of wastewater to a range of 2.5-3.
