摘　　要： 以印染废水为处理对象,以D301大孔树脂为吸附剂,选取次氯酸钠溶液为再生氧化剂,对吸附-氧化再生法处理印染废水的可行性及其影响因素进行了试验研究。结果表明:D301大孔树脂对印染废水有较好的吸附性能,其COD平衡吸附量可达166.2mg/g;当吸附剂再生时间为20min时,COD再生率可达83.8%。以D301大孔树脂为吸附剂、次氯酸钠溶液为再生氧化剂的吸附-氧化再生法处理印染废水具有处理时间短、操作灵活的优势,吸附剂的氧化再生时间短、再生率高,有很好的可行性和良好的应用前景。 With printing and dyeing wastewater as the treatment object, using D301 macroporous resin as adsorbent and sodium hypochlorite as regeneration oxidant, the feasibility of the adsorption-oxidation regeneration process treating printing and dyeing wastewater and the influencing factors thereof were studied through the test. The results showed that： D301 macroporous resin was able to adsorb the pollutants in printing and dyeing wastewater effectively, its COD equilibrium adsorption capacity reached 166.2 mg/g. When the adsorption regeneration time of the adsorbent was 20 min, the regeneration rate of COD reached 83.8%. It was indicated that, as the oxidation regeneration time of the adsorbent was short and its regeneration rate was high, the adsorption-oxidation regeneration process with D301 macroporous resin as the adsorbent and sodium hypochlorite as the regeneration oxidant had a good feasibility and application foreground in printing and dyeing wastewater treatment for its short treatment time and flexible operation.
