摘要
活性炭吸附催化氧化法处理含氰废水新工艺,其原理是在载体上,有催化剂存在的情况下,空气中的氧作为氧化剂,把CN-氧化成NH4+,完成除氰的作用。处理废水指标稳定、设备投资少、操作简单、原料来源方便、处理成本低。在技术上先进,经济上从投入性转为盈利性污水处理,具有较高的推广应用价值。获得较好的环境效益、经济效益和社会效益。
Utilizing oxygen in the air as oxidant to oxidize CN- on the carrier to NH4+ in the presence of catalyzer, thus carrying out the removal of cyanide is the very mechanism of the technology to treat cyanide-bearing wast water by activated carbon adsorption/catalytic oxidation method. By this method to treat waste water,the treatment index is stable with less capital cost, easy operation and convenient supply of raw materials.Having marked economic and social benefit, it is an advanced technology worthy to be popularized.
