氰化物是剧毒物质,人的致死量是0.03克,国家计委及卫生部规定地面水中氰化物的含量不得超过0.1毫克/升。因此,由冶金厂、选矿厂、电镀厂、热处理厂、化工厂、煤气厂、炼焦厂等排出的含氰污水,必须经过处理,才能往外排放。目前处理含氰污水的方法较多,活性炭催化氧化法是近几年发展起来的一个新的方法。用活性炭催化氧化含氰污水, Cyanide is a highly toxic substance, the human lethal dose is 0.03 grams, the State Planning Commission and the Ministry of Health, cyanide content of surface water shall not exceed 0.1 mg / l. Therefore, cyanide-containing sewage discharged from metallurgical plants, concentrator plants, electroplating plants, heat treatment plants, chemical plants, gas plants, coking plants, etc. must be treated before they can be discharged outside. At present, there are many ways to deal with cyanide-containing wastewater. The catalytic oxidation of activated carbon is a new method developed in recent years. Catalytic oxidation of cyanide-containing wastewater with activated carbon,
