摘　　要：采用催化氧化法,对Cu^(2+)<15mg/l,CN^-<25mg/l,Cu^(2+)/CN^-摩尔浓度比在0.1～0.7的铜氰废水进行处理。反应条件控制在:pH7.0～8.5,滞留时间45分钟,液固比在0.7～1.5ml/g,空气容量为30～50ml/l。在S催化剂作用下,处理后出水Cu^(2+)和CN^-浓度可符合排放标准。本装置处理费用0.07元/吨。再生简单,操作方便。The Cyanide coppe waste water with Cu^(2+)<15mg/l, CN^-<25mg/l and a Cu^(2+)/CN^- mole-ratio 0.1-0.7 was treated by catalytic oxidation under the conditions: pH7.0-8.5, retention time 45min., liquid/solid ratio 0.7-1.5ml/g and air content 30-50ml/l. After treated with S catalyst, the Cu^(2+) and CN^- concentration of the effluent accorded with the discharge standard. The cost of the treatment was 0.07 yuan/M^3 wastewater. It was convenient to operate and regenerate.
