我厂一直采用纯氰化物进行汽车零件的液体氰化,由于找不到一种有效的彻底中和去毒处理方法,废氰盐愈积愈多。废氰盐中氰化物的含量很高,不仅废氰盐的保管成问题,而且时刻有扩散和污染危险。为此,我们进行了中和处理试验工作。中和处理法均属氧化法,其中以热态处理法效果最佳,再经冷态处理或用废水稀释后,完全达到了国家规定的含氰污水排放标准。现将用硫酸亚
Our factory has been using pure cyanide for liquid cyanide auto parts, because they can not find an effective and thorough detoxification methods, waste cyanide more accumulation. Cyanide waste cyanide high levels of content, not only waste cyanide storage problems, but always have the risk of proliferation and pollution. To this end, we conducted a neutralization test. Neutralization treatment method is oxidation method, of which the best heat treatment method, and then after cold treatment or diluted with wastewater, fully meet the state requirements of cyanide-containing wastewater discharge standards. Asia will now use sulfuric acid
