Abstract:

The experiments aim at the acidic colliery effluent with highly concentrated suspended matter in the process of coal production. The technology of the processtreatment of effluent"gravitational settling-neutralizing filter-aeration-coagulation-filtration"has been studied. The experiments proves that this technology can neutralize the acidic colliery effluent, as well as has better removal rates of SS, Fe, Mn, SO_{4^2-. The application of the equipment designed integratively proves that its results can meet the demands of discharge standard.}

Key words: suspended matter, acidic, colliery effluent, limestone, filter tank

摘要：

以煤矿生产过程中产生的高悬浮物酸性矿井污水为实验对象，研究了“重力沉淀-中和滤池-曝气-混凝-过滤”污水处理工艺，实验证明该工艺在中和酸性矿井污水时具有较高的SS、Fe、Mn、SO_{4^2-去除效果。通过实验设计的一体化处理设备应用于实践，证明经该工艺处理后出水可达排放标准要求。}
