摘要
采用活性炭吸附-酸化法回收处理氯氰菊酯含氰废水,研究结果表明,以0.1%活性炭进行预处理后,盐酸调节p H值为2~3,鼓泡吹氰,30%氢氧化钠吸收,氰化物去除率可达99.9%,降低了生态破坏。
Cyanide - containing wastewater in cypermethrin by activated carbon adsorption - acidification method , theresults indicated that more than 99.9% removal rate of cyanide was achieved under the following reaction conditions with 0.1% activated carbon to pretreatmemt , hydrochloric acid to adjust pH for 2 - 3, bubble blowing cyanide by 30% sodiumhydroxide absorption, and the ecological destruction was reduced.
