| 摘 要： | 采用含邻苯二甲酸二(2-乙基己基)酯(DEHP)的试验水样模拟城市取水水源发生DEHP水污染事故,测定粉末活性炭(PAC)对水样中DEHP的吸附性能,考察PAC炭种、吸附时间、DEHP初始浓度和PAC投加量等因素对DEHP的吸附量和脱除率的影响。试验结果表明:木屑PAC具有较大的比表面积,对DEHP具有良好的吸附效果,适用于DEHP水污染的应急处理。应急处理一般的DEHP水污染事故,DEHP污染浓度超标10～30倍时,PAC吸附DEHP的最佳条件为:吸附时间120 min,PAC投加量为20～80 mg/L,PAC对DEHP的吸附过程符合Henry等温式。

| Abstract: | Diethylhexyl phthalate polluted water was treated with PAC adsorption. The effects of different sorts of PAC, adsorption time, initial concentration and adsorbent dosage were investigated. The results show that the adsorption of diethylhexyl phthalate fol- lows Henry isotherm. The PAC with a high specific surface area exhibited a high capacity for DEHP, the greater suitability for the DEHP water pollution. The best PAC adsorption effect of treatment for average diethylhexyl phthalate pollution was acquired at ad- sorption time 120 rain, adsorbent dosage 20~80 mg/L. |
