| 摘 要： | 通过静态和动态试验研究了水合氧化锆吸附剂的适宜的pH值、剂量效应、动力学性能、重复利用性能.试验表明,该吸附剂在pH值为2.0～4.0范围内时吸附性能较佳;原水氟化物含量为3.72 mg/L时,吸附剂添加量为0.5g/100mL即可将氟化物浓度降至1.0 mg/L以下.试验中调节原水pH值至3.0,控制柱内停留时间为3 min,连续进行了3个周期的吸附-脱附试验,证明水合氧化锆吸附剂具有良好的洗脱性能,可多次重复利用.

| Abstract: | The adaptable pH,effect of dose,dynamic performance and capacity of reuse of the hydrous zirconium oxide absorbent are studied through the relevant static and dynamic experiment.The experiment shows that the absorption performance of the absorbent is better when pH is within a range of 2.0~4.0;for the raw water with the fluoride content of 3.72 mg/L,the fluoride concentration can be lowered below 1.0 mg/L,if the dosage of the adsorbent is 0.5 g/100 mL.In the experiment,3 cycles of column experiments of adso... |
