酚氰废水对水源保护区域污染的应急控制技术研究

酚氰废水中的挥发酚和氰化物具有毒性大、难降解等特点,需开发快速有效的事故泄露污染控制技术,初步探索了影响氧化挥发酚和氰化物的影响因素,以选取快速达标处理酚氰废水方法.实验结果发现单独应用Fenton氧化法对酚去除率高达99.94%,氰化物去除效率仅为31.28%;Fenton氧化法与氯化法复合处理酚氰废水,酚的去除率达到99.98%,氰的去除率显著提高,达到96.98%.

Contingent plans of waste water with phenol and cyanogen pollution to the source area of the tap water the technology for contamination controling

The wastewater with the volatile phenol and cyanide being toxic, hard to biodegradable, and needing timely and effective emergency pollution control, the waste water treatment technology of the Fenton oxidation is employed. Moreover,the influential factors of oxidizing the volatility phenol and the cyanide are explored by initially studying the processing efficiency of Fenton oxidation to the waster wa- ter under dissimilar condition. And the experimental results show that the Fenton oxidation is only used to process the waster water, the elimination rate of phenol will reach as high as 99.94% and the elimina- tion rate of cyanogens will only reach as high as 31.28 % ;Howerver,if a combining the Fenton oxidation and Chlorination to process the waster water,the elimination rate of phenol enhances to 99.98 % and that of cyanogens reaches 96.98 %.
