摘要
以高含盐量的神东煤矿矿井水为研究对象,利用可调温冰柜提供的冷冻环境,研究冷冻对各离子的去除效应。结果表明,经过低温冷冻后,矿井水表现出很好的冷冻分凝效果,冷冻对阳离子的去除率明显大于阴离子的;冷冻时间、冷冻温度、离子的初始浓度和加入种冰都影响冷冻对各离子的去除效应:随着冷冻时间的增加,各离子的去除率逐渐升高;随着冷冻温度的降低,各离子的去除率也随之降低;较高的初始离子浓度降低冷冻对各离子的去除效率;种冰的加入可以提高各离子的去除率。
The mine water with high salinity from Shendong coal mine is selected as the sample in this study. The temperature-con- trollable refrigeratorsolution is used to supply frozen environment and the removal rate of every ion in freezing environment is investi- gated. The results indicate that more cation can be removed than anion after being frozen. The removal rate is affected by freezing time, freezing temperature and initial concentration of ion. The removal rate increases with the increase of freezing time, the raise of freezing temperature, the reduction of initial concentration of ion and the adding of seed ice.
