新型家用除砷氟净水器研制与试验研究

针对我国部分地区饮用水砷、氟含量超标问题,设计出一种分散型的家用净水器,以预氧化—吸附—膜处理为技术路线,以曝气—改良活性炭—活性氧化铝—反渗透膜为实际组成单元,分别对单独除砷、单独除氟、砷氟共除效果进行实验测定。实验结果表明,单砷浓度1.994 mg/L,单氟浓度（以F-计）4.925 mg/L,及砷氟共存砷浓度2.128 mg/L,氟浓度（以F-计）5.293 mg/L时,出水砷氟浓度均符合《生活饮用水卫生标准》（GB 5749-2006）。砷氟共除时,浓水砷氟含量符合《污水综合排放标准》（GB 8978-1996）,可以安全排放。说明此净水器方法可行,有实用价值。

Research of New Home Water Purifier for Removing Arsenic and Fluoride

Aiming to solving the problem that the drinking water in some areas containing excessive arsenic and fluoride,we designed a scattered household water purifier.The technical route would be pre-oxidation first,then adsorption and film processing.The actual units would be composed by the aeration,modified activated carbon,activated alumina,and reversed penetration membranes.Three separate tests would be taken on filtering arsenic alone,fluorine alone,and filtering arsenic and fluoride together.Experimental res...
