摘　　要：目的筛选更加有效实用性强的饮水除氟材料。方法通过实验室模拟检测分析,对改性超高分子质量聚乙烯(UHMWPE)微滤膜在用于饮水除氟时,出水流量、含氟浓度对除氟效果的影响,以及使用条件、再生使用等性能进行了研究。结果在有效过滤膜面积为140 cm2,出水流量为3 L/min时,可使60 L含氟浓度为3 mg/L水得到有效净化,而且出水含氟量保持在0.48～0.93 mg/L之间,符合国家生活饮用水卫生标准。微滤膜的动态饱和吸附容量为0.44mg/cm2,反复再生6次后,吸附容量可恢复85%以上。结论改性超高分子质量聚乙烯微滤膜具有除氟效果明显,稳定,使用周期长,使用方便。对于饮水除氟具有较高的使用价值。Objective The screening more effective usability strong potable water eliminates the fluorine material. Methods This paper studied , while modified Ultra - high molecular weight polythylene membranes used in drinking water defluoridation, the capability, the condition of application and the performance of renewable application. Results When the effective membrane filter＇s area is 140 cm^2 and the water flow rate is 3 L/min, The membrane will purify effectively 60 L water which is in a fluoride concentration of 3 mg/L . In addition, the quantity of fluoride in the drainage kept at 0.48 to 0.93 mg/L, and in line with the state standards in the health of drinking water. The dynamic saturation adsorption capacity of membrane is 0.44mg/ cm^2. After repeatedly renew six times ,the adsorption capacity can resume more than 85 percent. Conclusions The modified superelevation molecular weight polyethylene micro filter diaphragm has eliminates the fluorine effect to be obvious, stable, the use cycle is long, easy to operate. Eliminates the fluorine regarding the potable water to have the high use value.
