摘要
构建连续产碱系统(Successive Alkalinity Producing System,SAPS),依次改变进水条件,研究其对酸性矿山废水处理效果,结果表明:进水pH>3.00,COD/SO_4~(2-)=2.0,HRT=48h条件下,SAPS瞬时出水pH达6.70左右,硫酸盐还原菌对SO_4~(2-)还原率可达70%,出水Fe浓度随运行时间增加而升高,瞬时出水中仍溶较多金属离子。对基于SAPS改进构建的成套处理系统进行动态实验,结果表明:系统最终能将高浓度废水的pH提升至8.08,各阴阳离子在各单元逐步净化,最终将废水中的SO_4~(2-)和Fe、Mn、Cu、Cd、Ni全部去除,并在运行中体现了成套处理系统良好的耐受性。
