摘　　要：以硫化氢和氨气的混合臭气为研究对象,在温度为2～8℃时,对经混合气驯化的生物滤柱进行效能试验,对其生物膜进行微生物的分离纯化.结果表明:采用该生物反应装置对硫化氢和氨气混合气体的处理是可行的,去除率可达99%.低温除臭的优势菌主要是耐冷的硫氧化菌和亚硝化菌,硫化氢的氧化产物为单质硫和硫酸根离子,氨气的产物以NO3-为主.The mixture of ammonia and hydrogen sulfide being the representative odor, the biofilter is well domesticated with the temperature of 2-8°C. Then the effects with the inlet of hydrogen sulfide alone and ammonia and hydrogen sulfide together are tested. The biofilm of it are isolated and screened. It indicates that it is viable to treat malodor by biofilter in low temperature. The removal efficiency is as high as 99 percent. The dominated bacteria is psychrotrophs deodorized bacteria. The main production of ammonia is nitrate and that of hydrogen sulfide is sulfate and sulfur.
