摘要
对低温等离子体处理粉尘中的二恶英初步研究的结果显示 ,正脉冲放电对粉尘中二恶英的处理效果较负脉冲放电的处理效果好。对不同毒性当量因子的二恶英同分异构体进行试验后发现脉冲放电对二恶英同分异构体的处理效率不同。一般来说 ,二恶英毒性越高 (毒性当量因子越大 )的同分异构体 ,用脉冲放电处理的效果越好 ,毒性当量因子最大的 2 ,3,7,8- T4 CDD分解效率最高 ,可达到 81%。
In this paper, non-thermal nanosecond plasma has been applied to detoxicate dioxin contained fly ash. The experimental results show that a positive pulse discharge provides higher destruction effect on the contained compounds than that does a negative one. It was found that different isomer compound shows different toxic removal effect and the higher the toxicity of the compounds is, the higher the destruction efficiency is. The 2, 3, 7, 8-T 4CDD compound which has the highest toxicity shows the highest destruction efficiency up to 81%.
