dc.description.abstract | A series of pilot-scale tests were conducted with a continuous system composed of a stirring tank reactor, settling tank, and sand filter. In order to treat acidic drainage from a Pb-Zn mine containing high levels of heavy metals, the potential use of coal-mine drainage sludge (CMDS) was examined. The pilot-scale tests showed that CMDS could effectively neutralize the acidic drainage due to its high alkalinity production. A previous study revealed that calcite and goethite contained in CMDS contributed to dissolutive coprecipitation and complexation with heavy metals. The continuous system not only has high removal efficiencies (97.2-99.8%), but also large total rate constants (K-total, 0.21-10.18 h(-1)) for all heavy metals. More specifically, the pilot system has a much higher Zn(II) loading rate (45.3 g m(-3) day(-1)) than other reference systems, such as aerobic wetland coupled with algal mats and anoxic limestone drains. The optimum conditions were found to be a CMDS loading of 280 g L-1 and a flow rate of 8 L day(-1), and the necessary quantity of CMDS was 91.3 g L-1 day(-1), as the replacement cycle of CMDS was determined to be 70 days.
