摘　　要：采用微絮凝工艺,选取煤矸石渣为滤料,对微污染矿井废水进行过滤试验,研究了絮凝剂投加量、滤柱截污性能、反冲洗情况及出水效果。试验结果表明,基于微絮凝的矸石渣深床过滤工艺具有较好的去除浊度和总铁的功能。处理工艺简捷,可节省药剂费和运行管理费。Using coal gangue slag as the media, the process of micro - flocculation has been used on filtration experiment for micro-polluted mine wastewater. The flocculant dosage, filter pil- lar capability, back-washing situation, and water quality of effluent were studied. The results showed that the process including coal gangue slag filter based on micro - flocculation filtration had satisfying performance on the removal of turbidity and total iron. This process is simple and can save costs on dosage, operation, and management.
