摘要：

城市水源水邻苯二甲酸酯（PAEs）污染对饮用水水质安全产生了威胁。综述了国内地表水（包括城市水源水）和给水厂处理出水中PAEs的污染情况，提出粉末炭（PAC）吸附与混凝沉淀联用技术（以下简称联用技术）是适合国内目前大多数水厂实情的可以有效应对水源水发生PAEs污染的水处理技术。开展了联用技术对原水中邻苯二甲酸二（2-乙基己基）酯（DEHP）的去除效能的实验研究。结果表明，联用技术可以有效地去除原水中DEHP，处理出水浊度是影响DEHP去除效果的重要因素，PAC理化特征对联用技术去除原水中DEHP效果的影响不大。最后基于小试实验结果给出了不同污染水平下联用技术中PAC的建议投量，为实际生产提供了技术参考。

Abstract:

The pollution of phthalate esters(PAEs) in water source of cities is a threat for the safety of drinking water quality.PAEs pollution in the domestic surface water(including water source) and the treated water in water works were reviewed.A combination method of adsorption by powdered activated carbon(PAC) and coagulation-sedimentation was proposed, which can be a suitable technology and coping measure to PAEs pollution in raw water for most water plants in China.Then the removal efficiency of di(2-ethylhexyl) phthalate(DEHP) by the combination technology was experimentally studied.The results show that the technology can remove DEHP effectively in water.The turbidity of treated water is an important influencing factor for the removal of DEHP.The effect of PAC’s physical and chemical properties on the removal of DEHP from raw water is small.The recommended dose of PAC in the combination technology was given based on the lab experimental results obtained at different pollution levels of DEHP, which can be a technical reference for practice.
