试验采用紫外光化学技术对含硫化氢恶臭气体进行处理，结果显示，光化学系统可以对硫化氢恶臭气体进行很好的处理，使排放的废气达到国家规定的排放标准。试验对影响光化学治理恶臭的各种因素，如光强、臭氧量、进气浓度、风量、喷淋等进行的分析表明，通过臭氧量和光强的增加，硫化氢的去除率可以得到提高，而当光强>6 mW/cm2时增大光强几乎不影响降解速率。分析表明，当硫化氢浓度升高到一定水平后，光化学降解反应的速率不再变化；而随着风量的增加，去除率从95％以上下降至80％左右。

UV-photochemistry technology was used to treat hydrogen sulfide odor. The results showed that hydrogen sulfide odor can be treated in the photochemical system. Off-gas quality could reach national exhaust standard. Factors that influence the effect of odor treatment by photochemical method, such as light intensity, amount of ozone, concentrations of initial gas, air volume, spray, and so on, were analyzed. By increasing the amount of ozone and light intensity, the removal rate of hydrogen sulfide can be increased. When the light intensity greater than 6 mW/cm2, it can not affect the degradation rate. When the concentration of hydrogen sulfide increased to a certain level, the photochemical degradation rate has no change. With the increase of air volume, the removal rate decreased from 95%to 80%.
