酸性含煤矿废水由于ph低（2.4左右），SS、Fe、Mn浓度高．对水源影响大。本文根据林东煤矿废水的特征，提出了治理工艺实验，提出二次曝气二级锰砂氧化过滤处理流程，经实验运转取得了很好的治理效果。
Acid coal mine wastewater due to ph low (2.4 or so), SS, Fe, Mn high concentration. Great impact on water. Based on the characteristics of Lin Dong coal mine wastewater, this paper puts forward the experiment of treatment process, puts forward the secondary aeration two manganese oxide oxidation filtration process, and achieved good treatment effect through the experimental operation.
