气氛含氧量对DDT热处理特性的影响
Effect of oxygen content on heat treatment characteristics of DDT
摘要
Abstract
DDT is a kind of organochlorine pesticide,the DDTs in the pesticide are of hard-degradation and biological toxicity.In order to provide theoretical basis for developing high-temperature process on treating obsolete DDT,high temperature tube furnace was used to research the effect of oxygen content on heat treatment disposal characteristics of DDT.The results showed that,the destruction efficiency of DDT could reach 70.48% at 600℃ in the 21% oxygen atmosphere and be over 99% at 900℃ under the condition of 21% oxygen content only,at 1 200℃,it was over 99.9% when the oxygen content reached 12%.In the combustion residue,the percentage of o,p＇-DDT in DDTs increased and the percentage of DDT reduced as the oxygen content rose under three temperature conditions,and the changes became distinct as the temperature increased.In the tail gas,the percentage of p,p＇-DDE in DDTs increased as the oxygen content rose under three temperature conditions,and the phenomenon was more obvious at 1 200℃.关键词
