| 中文摘要: |
| 针对河北省清河县高氟地下水的高pH 值（8.3）、高氟浓度（3.6 mg/L）的水质特点，以新型高效Fe-Al-Ce除氟吸附剂为核心，设计了含预处理、活性炭吸附和超滤单元的小型吸附装置用于家庭终端高氟水的处理。在清河高氟原水现场，对不同空间流速（SV）和不同运行方式条件下的Fe-Al-Ce吸附剂除氟性能和装置出水安全性进行了研究评价。结果表明，在SV=1 h-1 条件下，装置运行效果良好，Fe-Al-Ce吸附剂除氟穿透吸附容量为活性氧化铝的3倍以上，装置出水的金属浓度符合标准要求，超滤单元对微生物有截留作用，但其微生物安全性还需进一步提高。 |
| 英文摘要: |
| To remove excess fluoride from Qinghe groundwater of Hebei province which is characterized by a high fluoride concentration （3.6 mg/L） and a high pH（8.3）， small scale equipment including the pre-treatment， active carbon adsorption and ultra filtration units was applied and the adsorbent was Fe-Al-Ce tri-metal complex oxide with high fluoride adsorption capacity. In the site of Qinghe with high fluoride water，the different space velocity （SV），and operation mode effects on the fluoride removal performances of Fe-Al-Ce adsorbent were studied and the safety of equipment effluent water were evaluated. The results show that the household adsorption equipment has good operation effects. At space velocity of 1h-1，the breakthrough adsorption amount of the Fe-Al-Ce adsorbent was more than three times the value of active alumina. The metal contents of equipment effluent water met the national drinking water standards.The
influent water quality was improved by active carbon adsorption. And the ultra filtration unit was useful for the microorganism retention，but its microorganism safety should be further studied. |
