摘要
在实验室以配制的含H2 S复合恶臭气为对象 ,研究H2 S的生物脱除工艺及二甲基二硫化物、甲苯的存在对H2 S脱除的影响。结果表明 ,H2 S入口负荷在 45g/ (m3 ·h)以下时 ,H2 S脱除率可接近 10 0 % ,并保持长时间的恒定 ,负荷波动幅度可达到 30 .3g/ (m3 ·h)。反应温度对H2 S脱除有较大影响 ,适宜的反应温度为 2 0℃以上 ;甲苯、二甲基二硫化物的存在对H2 S的生物脱除基本没有影响。
Deodorization of hydrogen sulfide in laboratory prepared complex malodorous gas containing hydrogen sulfide, dimethyl disulfide and toluene by peat bio filter, and the presence of dimethyl disulfide and toluene in the gas on the effect of hydrogen sulfide removal were studied respectively. The results showed that the hydrogen sulfide removal rate was about 100% and could be kept for a long time at an inlet load of hydrogen sulfide less than 45g/m 3·h . The effect of reaction temperature on hydrogen sulfide removal was significant, the appropriate temperature was higher than 20 ℃. The malodorous gas containing dimethyl disulfide and toluene showed little effect on hydrogen sulfide removal. The said deodorization method is proposed to purify the malodorous gas from wastewater treatment.
