Research Progress on Toilet Odor Composition and Treatment Technology
Toilet odor is mainly caused by a mixture of gases such as hydrogen sulfide,methane and ammonia,which is generally caused by vol-atile substances such as mixed gases produced by fermentation and metabolism of human excreta.The presence of odor not only affects the com-fort of life,but may also have an impact on health.Therefore,the management of toilet odor has become an important issue.This thesis reviews the sources,composition,hazards and commonly used deodorization technologies of toilet odor,aiming to provide a reference for the research and development of new,efficient and low-cost technologies for the management of toilet odor.
