研究了Fenton试剂对甲基丙烯醛生产废水的处理效果,考察了[H_2O_2]/[Fe~2+]摩尔比,H_2O_2初始浓度,pH值,反应时间,温度对废水COD_(cr)去除率的影响,确定了最佳的COD_(cr)去除率条件.结果表明:当pH=2.5,[H_2O2]/[Fe~(2+)]摩尔比为26.4:1,温度为25℃,反应时间为5 h,甲基丙烯醛生产废水COD_(cr)浓度为812 mg/L时,COD_(cr)去除率达71.4%,处理效果良好.
研究瞭Fenton試劑對甲基丙烯醛生產廢水的處理效果,攷察瞭[H_2O_2]/[Fe~2+]摩爾比,H_2O_2初始濃度,pH值,反應時間,溫度對廢水COD_(cr)去除率的影響,確定瞭最佳的COD_(cr)去除率條件.結果錶明:噹pH=2.5,[H_2O2]/[Fe~(2+)]摩爾比為26.4:1,溫度為25℃,反應時間為5 h,甲基丙烯醛生產廢水COD_(cr)濃度為812 mg/L時,COD_(cr)去除率達71.4%,處理效果良好.

. Fenton's reagent that was employed for treating the wastewater coming from methacrolein prod-uction was studied. The effects of reaction time, [H_2O_2]/[Fe~(2+)] mole ratio ,pH value, initial concentration of H_2O_2,and temperature on COD_(cr) removal were investigated. The results showed that 71.4% of COD_(cr) was removed under the optimum conditions : COD_(cr)=812 mg/L, [H_2O_2]/[Fe~(2+)]=26.4:1,pH=2.5, 25 ℃, 5 h.
