摘要

本文探索研究用辐射技术处理焦化厂废水中的氰化物。研究表明，电离辐射可将剧毒的氰化物转变为无毒或毒性较小的产物。单独用辐射技术处理焦化厂废水时，体系中的有机污染物与氰化物竞争水辐解形成的活性粒子(H、e,-,aq,、 OH自由基）抑制氰化物的辐射分解。用活性炭预处理废水可以提高废水中氰化物和有机物的辐射去除率。H,2,O,2,和N,2,O通过转变e,-,aq,成为OH自由基提高了氰化物的分解，OH自由基在降低氰化物和COD值方面起着重要的作用。

Abstract

The treatment of cyanide in waste water of coke-oven plant with radiation-technique was investigated. The investigation indicated that toxic products. under γ-ray irradiation were changed into less-toxic or non-toxic products. Organic pollutants will compete with cyanide for scavenging active intermediates of water (H,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42649972&type=,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42649974&type=,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42649973&type=, and OH radical). Therefore, it will inhibit cyanide radiolysis. The pretreatment with active carbon increases the radiolytic decomposition rate of cyanide and damage rate of organism in waste water. H,2,O,2, and N,2,O convert ,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42649975&type=,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42649977&type=,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42649976&type=, into OH radical. however they improve the efficiency decomposition of cyanide. OH radical plays an important role in reducing cyanide content and COD value.
