Preliminary study on odor removal by ozone applying in fecal treatment workshops

Objective Ozonizafion is one of the methods for removing odor in fecal treatment workshop and results in odor removal or less unpleasant smell.Methods This paper has a determination on pollution source and calculation of odor removal efficient in fecal treatment workshop based on measurement data by subjection judgement and chemical analysis on site. It has also a discussion on suitable ozone eoncentratiun for odor removal. Results Under the condition of ozone, the hydrogen sulfide and ammonia in odor are controlled in fecal treatment workshop. Conclusion Being used ozone, the removal efficiency of hydrogen sulfide is higher than of ammonia in gas phase. The removal efficiency of hydrogen sulfide is 88% and removal efficiency of ammonia is 56.5% for two-hour continual testing period.
