摘要
应用生物-光催化联用工艺对广州市猎德污泥中转站的4 000 m^3/h臭气进行了处理。检测结果表明:组合工艺对氨气去除率达98.7%,对挥发性有机废气(VOCs)去除率为87.3%,主要的致臭污染物氨气、二甲基硫醚及二甲基二硫醚都能达标排放,臭气浓度降低97.2%,显著改善了周边空气质量。
A combined system of biofilter and photocatalytic reactor was used to control the odorous gases with a flow rate of4 000 m^3/h emitted from the sludge transfer station of Liede in Guangzhou,China. The results showed that the removal efficiencies of NH_3,VOCs and the odor concentration obtained by the combined reactor were 98. 7%,87. 3% and 97. 2%,respectively. The outlet concentration ammonia,dimethyl sulfide and dimethyl disulfide could meet the emission standards set by the Chinese Ministry of Environment Protection,hence this process can significantly improve the ambient air quality.
