摘　　要：传统的净水过程一般包括混凝—沉淀—过滤消毒工艺流程,主要去除水中的浊度和细菌,大部分有机物、有害的重金属仍残留在水体中。对活化沸石、聚苯乙烯树脂、活性炭3种材料的净水能力进行了研究。由于3种材料对饮用水中有害物质的去除主要以吸附作用为主,所以在水处理方法中主要阐述了吸附法,包括吸附的机理、吸附的类型、吸附的影响因素。在实验部分,以自来水出水中的铝离子为参照物,利用《生活饮用水卫生标准》国家标准检测方法分别测算出3种材料对铝离子的去除率,借此来比较3种吸附材料的吸附特性。The traditional water purification process generally includes coagulation-sedimentation-filtration and disinfection process,which mainly remove turbidity and bacteria,but most of organic matter and toxic heavy metals still keep in the water.This paper investigates the purification capacity of three materials,activated zeolite,polystyrene resin and activated carbon.This paper mainly discusses adsorption,including adsorption mechanisms,types and influence factors.In the experiment,aluminium ions from water are used as references and the removal rates of the three kinds of adsorbent materials to aluminum ions are respectively measured,by using the national measurement standard method 'Sanitary Standard for Drinking Water'.
