摘要
加压水解脱氰是去除难降解的含氰废水中氰化物的有效方法之一．尽管在理论上脱氰后出水［ＣＮ－］可以小于０．５ｍｇ／Ｌ，但是，生产上达到该指标有相当难度．为此，我公司经过十来年的研究和生产探索，至１９９４年实现达标，目前反应出水［ＣＮ－］在０．３５ｍｇ／Ｌ左右．根据大量文献资料和生产数据，对脱氰反应影响因素和生产工艺参数进行理论和实践分析，找到了优化的参数搭配．
An effective method to remove the difficult decomposition cyanogen in cyanogen wastewater is the pressurized hydrolysis.It was based on the theory that the[CN-] can be low 0.5mg/L,but it is difficult to reach this removal level.The Zhenhai Petrochemical Corporation,Ltd reached the [CN-] about 0.35mg/L since 1994 by study and research for decade.
