摘要
采用酸化-活性炭吸附法处理含氰废水。研究结果表明,经酸调节废水pH为酸性或弱酸性,鼓泡吹氰,然后活性炭吸附脱色后,盐水中氰化物的浓度可小于10ppm,COD小于2000ppm,实现了氰化钠的回收,降低了盐水的生态破坏。
The acidification-activated carbon adsorption was employed to treat cyanide-containing waste water in cartap. The research results indicated that the concentration of cyanides in the aqueous solution of the salts is below 10 ppm and COD below 2000 ppm,under the following reaction conditions with weakly acidic waste water adjusted by acid,bubble blowing cyanide,activated carbon adsorption to decolor,thus the recovery of sodium cyanides is achieved and the damage to ecology is also minimized to a great extent.
