摘要

在本研究中，石灰的混合物用于处理酸性矿井水(AMD)或酸性岩石水(ARD)。结果表明，酸橙混合剂(CHL)可以治疗AMD。CHL是碳化物和水合石灰的混合物。砷(As)与CHL反应后降低。选择0.5 g CHL，间隔时间为20 min作为治疗AMD的最佳参数。pH值从3.29上升到6.69，浓度从3.273 mg/L下降到0.002 mg/L。反应后得到的两个结果都符合1974年环境法的A和B标准。

The Mixture of Limes in Acid Mine Drainage Treatment

In this study the mixture of limes was used to treat acid mine drainage (AMD) or acid rock drainage (ARD). The results showed that AMD can be treated by a mixture of limes (CHL). CHL was a mixture of carbide and hydrated limes. Arsenic (As) was decreased after reaction with CHL. 0.5 g of CHL with an interval time of 20 mins was chosen as the best parameter for treating AMD. pH value was increased from 3.29 to 6.69 and as concentration was decreased from 3.273 mg/L to 0.002 mg/L. Both of the results obtained after the reaction complied with Standards A and B of the Environmental Act 1974.
