摘要: 为解决淄博市岳阳河地下酸性矿井水涌出污染环境的问题,设计采用石灰中和/充氧曝气/混凝沉淀/多级过滤组合工艺对该矿井水进行处理,文章对酸性矿井水处理的工艺流程、设计参数确定及工艺特点等进行了详细介绍。工程实践结果表明,当进水水质COD、NH3-N、SS、总Fe、Mn分别为46,27,24,395,7 mg/L时,采用该矿井水处理工艺,出水水质达到16,0.9,6,0.4,0.2 mg/L,说明矿井水水质得到有效改善,该组合处理工艺对于处理酸性矿井水具有较好的处理效果。

Abstract: In order to solve the problem of environmental pollution caused by underground acid mine water gushing to Yueyang River in Zibo, a combined process of lime neutralization/oxygenation aeration/coagulation sedimentation/multi-stage filtration for treating mine water is designed. And its technological process, design parameters and technological characteristics are introduced in the article. As the results of engineering practice show, when the levels of COD, NH3-N, SS, total Fe and Mn in inlet water are 46, 27, 24, 395 and 7 mg/L respectively, the levels of outlet water are 20, 2.3, 6, 0.4 and 0.3 mg/L respectively, the quality of mine water has been effectively improved. It can be seen that the combined treatment process has a good effect for the treatment of acid mine water.
