山药絮凝剂的制备及其对农村饮用井水的净化性能

Preparation of Rhizoma Dioscoreae Flocculant and Its Performance on Purifying Rural Drinking Well Water

以天然山药为主要原料制备了液态天然型山药絮凝剂,并将其用于净化农村饮用井水,考察其对井水浊度、硬度、矿化度的影响情况。实验结果表明,所收集的农村饮用井水样品浊度、硬度、矿化度分别为:4度、298.4mg/L、436 mg/L;使用所制备的山药絮凝剂净化后,水样浊度、硬度、矿化度分别降低至:1度、179.4 mg/L、310 mg/L。可见,所采集的农村饮用井水样品经山药絮凝剂处理后水质得到明显提升,这表明所制备的山药絮凝剂具有较好的井水净化性能,从而可为农村饮用井水安全提供一定程度的保障。

Natural rhizoma dioscoreae flocculant was prepared and used to purify the rural drinking well water.The effects of rhizoma dioscoreae flocculant on turbidity,total hardness and salinity of well water were investigated.The results reveal that the turbidity,total hardness and salinity of rural drinking well water sample are4degree turbidity,298.4mg.L-1and436mg.L-1,respectively.After purification by using the as-prepared rhizoma dioscoreae flocculant,the turbidity,total hardness and salinity of water sample are reduced to1degree turbidity,179.4mg.L-1and310mg.L-1Respectively.We can see that the water quality of collected rural drinking well wa-ter sample is significantly improved by the purifying of as-prepared rhizoma dioscoreae flocculant.It indicates that the as-prepared rhizoma dioscoreae flocculant has superior performance on purifying rural drinking well water and hence,safeguard the safety of rural drinking well water to a certain degree.
