树脂吸附法处理癸二酸生产中含酚废水的试验研究

REMOVING PHENOL FROM SEBACIC ACID WASTEWATER USING RESIN ADSORPTION

用ＮＫＡ树脂对癸二酸生产中排出的含低浓度乳化油（＜２．０ｍｇ／Ｌ）及低浓度酚（３０ｍｇ／Ｌ）废水进行脱酚处理，处理后水质达到国家排放标准。并用１ｍｏＬ的ＮａＯＨ溶液对树脂床进行脱附，在室温下，其效率大于７０％。根据理论分析及实验参数，得到了较为理想的树脂吸附酚的理论公式。

The treatment of phenolic wastewater from sebacic acid processing using the NKA resin adsorption was investigated. Emulsified oil and phenol of the raw wastewater were lower than 2.0mg/L and 30 mg/L, respectively. The treated wastewater quality met the requirement of National Wastewater Discharge Standard. The resin bed was desorbed by using 1mol of NaOH. Desorbing efficiencies were more than 70% at normal atmospheric temperatures.Based on the theoretical analysis and experimental parameters,a comparatively ideal theoretical formula of removing phenol by using resin adsorption has been developed.
