摘要
研究了大孔树脂吸附法处理直接红印染废水.考察了废水pH值、废水浓度、吸附时间和吸附剂用量对色度和浓度去除率的影响.结果表明:在pH值为8,废水浓度为9mg/L,反应时间为2小时,100ml废水中吸附剂用量为3g时,废水的色度去除率为93.9%,浓度去除率为97.9%.大孔树脂的重复使用性能良好.
Direct red simulation printing dye wastewater was treated with macroporous resin absorption in this paper.The effects of concentration and pH of the wastewater, absorption time and absorber dosage on color and concentration removal rate was investigated.The result shows that color removal rate is 93.9% and concentration removal is 97.9% when wastewater pH=8, react time is 2 hours and absorber dosage is 3g in 100ml water. The reusing capability of the macroporous resin is good.
