摘要: 采用新型超高交联树脂NDA-66处理增塑剂DBP生产废水,对比不同吸附剂对DBP生产废水中的邻苯二甲酸的吸附效果,考察了吸附时间、pH、温度、流速和不同初始溶液浓度对NDA-66静态吸附效果的影响。结果表明,NDA-66对邻苯二甲酸的最佳吸附条件为pH 2.0,温度30℃,最佳静态吸附时间为12h。经过8批次连续吸附-脱附后,NDA-66树脂对邻苯二甲酸的去除率在94%以上,脱附率在90%以上,回收邻苯二甲酸晶体纯度高达95%,实现了废水有用物质的资源化。

Abstract: A new hypercrosslinked polymeric resin NDA-66 was selected to treat the wastewater generated from production of plasticizer dibutyl phthalate. In the study, the effects of different adsorbent on o-phthalic acid (o-PA) adsorption were compared. The influences of time, pH, temperature, flow velocity and different initial solution concentration on static o-PA adsorption of NDA-66 were investigated. The results showed that the optimal operating conditions for resin NDA-66 adsorption were pH of 2.0,temperature at 30℃, and static adsorption time of 12 hours. After 8 times of continuous adsorption and desorption with resin NDA-66, the o-PA adsorption rate was over 94%, the resin desorption rate was over 90% and the purity of o-PA crystal reclaimed reached to 95%. Therefore, resource recovery of the useful materials from the wastewater was realized.
