摘要
研究了直接酸洗复苏法、树脂转为氯型后酸洗复苏法、氯化钠转型后用次氯酸钠氧化复苏法、次氯酸钠氧化后用盐碱混液复苏法、双氧水氧化后用盐碱混液复苏法等五种不同的复苏方法对铁和有机物污染树脂复苏效果的影响。结果表明:复苏方法不同时,亚铁离子污染树脂的复苏效果和铁离子污染树脂的复苏效果是不相同的,同时可看出,双氧水氧化后盐碱混液复苏法复苏铁污染树脂的效果最好;五种不同的复苏方法对腐植酸污染的树脂都有较好的复苏效果,且复苏效果相差不大。
The effects of recovery of pollution resins are investigated using five different methods. The methods are as following： direct pickling resuscitation, pickling resuscitation after changed into chlorine -based, sodium hypochlorite oxidation resuscitation after restructured by sodium chloride, salinization mixed fluid recovery after oxidized by sodium hypoehlorite and salinization mixed fluid recovery after oxidized by hydrogen peroxide. It is shown that ： Using the different method of recovery, the effects of recovery of pollution ferrous ion resin is not the same of iron pollution resin; The method of salinization mixed fluid recovery after oxidized by hydrogen peroxide makes the best recovery of iron pollution; Five different methods for the recovery of pollutiofi humic acid resin has the same and better resuscitation.
