河北省清河县高氟地下水处理的试验研究

针对河北省清河县高氟地下水的高p H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。

Study on the treatment of high fluoride groundwater in Qinghe County,Hebei Province

To remove excess fluoride from Qinghe groundwater of Hebei province which is characterized bya high fluoride concentration（3.6 mg/L） and a high p H（8.3）,small scale equipment including the pre-treatment,active carbon adsorption and ultra filtration units was applied and the adsorbent was Fe-Al-Cetri-metal complex oxide with high fluoride adsorption capacity. In the site of Qinghe with high fluoride wa-ter,the different space velocity（SV）,and operation mode effects on the fluoride removal performances ofFe-Al-Ce adsorbent were studied and the safety of equipment effluent water were evaluated. The resultsshow that the household adsorption equipment has good operation effects. At space velocity of 1h- 1,thebreakthrough adsorption amount of the Fe-Al-Ce adsorbent was more than three times the value of activealumina. The metal contents of equipment effluent water met the national drinking water standards. The in-fluent water quality was improved by active carbon adsorption. And the ultra filtration unit was useful forthe microorganism retention,but its microorganism safety should be further studied.
