目的:利用臭氧对粪便处理车间的臭气物质进行氧化分解时,臭氧的除臭效果和臭氧的适宜浓度。方法:在对京东某粪便处理车间大规模现场测试(官能法,化学法)的基础上,确定粪便处理车间的恶臭污染源,计算出臭氧氧化法的除臭效率。结果:针对臭气成份与臭氧反应速度,绘制出了在粪便处理车间臭气浓度以及臭气主要成份硫化氢和氨随时间的衰减曲线;臭氧发生器启动后,臭气浓度迅速衰减,在第一个小时内臭气浓度衰减率为74%,硫化氢在第一个小时浓度衰减率为29%,第二个小时浓度衰减率为58.9%,氨2小时后总衰减率为56.8%;臭氧除臭时,粪便处理车间臭氧浓度应控制在0.03 ppm,此时臭气浓度为150,臭气强度为3级。结论:该项研究为臭氧除臭装置和粪便处理车间利用臭氧氧化法除臭提供了设计依据。
