• 中文摘要： 本文發展一電化學磁分法來處理電鍍鋅廢水,經處理後之廢水殘餘鋅及鐵離子濃度均低於0.05mg/l。文中探討pH、反應溫度、電流、鋅離子濃度對反應所需時間、溶解鐵重及汙泥沈降速度之影響。增加電流可減少反應所需時間,但增加溶解鐵重。提高反應溫度,可減少反應所需時間及溶解鐵重,而增加汙泥沈降速度。得一最佳pH來最小化反應所需時間及溶解鐵重,而最大化汙泥沈降速度。有外加磁場下之汙泥沈降速度大於無外加磁場下之汙泥沈降速度。
• 英文摘要： An electrochemical magnetization treatment was developed for wastewater from zinc plating in the present study. After the treatment, the residual concentrations of both zinc and ferrous ions were lower than 0.05mg/l in the wastewater. The effects of pH, reaction temperature, applied current and zinc concentration on the required time, the dissolved weight of iron and the sedimentation velocity of sludge were investigated. Increasing the applied current leads to decrease the required time but increasing the dissolved weight of iron for treatment. The required time and the dissolved weight of iron decrease and the sedimentation velocity of sludge increases with increasing the reaction temperature. An optimal pH was obtained to minimize the required time and the dissolved weight of iron and maximize the sedimentation velocity of sludge. The sedimentation velocity of sludge with a magnetic field is larger than that without a magnetic field.
