摘　　要：有机磷酸酯(OPEs)作为一种新污染物,已在我国多个城市的自来水中被检测出。为此,选择6种有代表性的OPEs单体,开展了预氯化工艺去除OPEs的中试研究。结果表明,预氯化对原水中OPEs有一定的去除效果,对6种OPEs的总去除率最高可达27.84%,其中对芳基有机磷酸酯的去除效果明显,对氯代有机磷酸酯的去除效果较差。综合考虑处理成本及消毒副产物的生成等因素,建议NaClO的最佳投加量为1.5 mg/L,在该投加量下预氯化可去除原水中23.73%的总OPEs。Organophosphate esters(OPEs)have emerged as a new environmental pollutant,and have been detected in the tap water of numerous cities across China.Therefore,six representative OPEs monomers were selected to investigate the efficacy of prechlorination in removing OPEs in a pilot scale test.Prechlorination had a specific impact on the removal of OPEs in raw water,with the maximum removal rates of six types of OPEs monomers reaching up to 27.84%.Notably,a pronounced removal performance of aryl organophosphate esters was observed,while the removal efficiency of chlorinated organophosphates was poor.After considering the cost of treatment and the generation of disinfection byproducts,it was recommended that the optimal dosage of NaClO should be 1.5 mg/L.This dosage resulted in the removal of 23.73%of the total OPEs in raw water.
