摘　　要：我国幅员辽阔,受区域环境季节等因素影响,各地区水质差异明显,近年来,研究不断发现水体中内分泌干扰物、抗生素等新型污染物,水污染形势愈发严峻。现有的饮用水处理系统对这些新型污染物的控制能力有限,家用净水器作为饮用水的最末端处理设施,近年来在居民家中占有率逐年上升。因产品材料结构组成多样、生产工艺复杂,潜在有害物质的种类和迁移不明,随着水污染时间不断增多,现有的检测技术无法精确量化产品品质,质量监管受到约束,因此对市面所售净水器精准净化能力提出了要求。本文以市售净水器为研究对象,建立了饮用水处理装置精准净化检测方法,对净水器中具体物质(如铅、砷等)的去除或净化能力进行评价,建立家用净水器对农药去除率测试方法、对抗生素去除率测试方法,通过对去除效果进行分级,指导消费者进行选购以及制造商技术升级。Due to the vast territory of our country,there are obvious differences in water quality among various regions,affected by regional environment,seasons and other factors.In recent years,studies have constantly found newpollutants such as endocrine disruptors and antibiotics in water bodies,and the water pollution situation has become increasingly severe.The existing drinking water treatment system has limited ability to control these new pollutants.The share of household water purifier,as the terminal treatment facility for drinking water,in residents’homes has increased year by year in recent years.Because of the diverse product material structure,complex production process,and uncertain types and migration of potentially harmful substances,with increasing water pollution,the existing detection technology cannot accurately quantify the product quality,and the quality supervision is constrained,which puts forward requirements of the precise purification capacity of commercially available water purifiers.Taking water purifiers as the research object,this paper establishes an accurate purification detection method for drinking water treatment devices,evaluates the removal or purification capacity of specific substances(such as lead and arsenic)of water purifiers,establishes a testing method for pesticide removal rate and antibiotic removal rate of household water purifiers,and grades water purifiers by the removal effect to guide consumers purchase and technological upgrading of manufacturers.
