摘要
分别以改性前后陶粒作为生物滴滤塔填料,进行去除H2S的对比实验研究。结果表明,改性后陶粒表面性质优于改性前陶粒;改性后陶粒挂膜时间短,对H2S降解菌有较强的吸附固定作用,适宜H2S降解菌生长,生物含量高;在H2S初始质量浓度为124～4396mg/m3时,改性后陶粒对H2S的去除能力优于改性前陶粒。
High temperature modified ceramic was prepared with FeCl3 as modifier at 400℃. Scanning Electron Microscope and X-ray diffraction analysis map were employed for the comparison of ceramic and modified ceramic. The results showed that modified ceramic was better than ceramic in the surface properties for α-Fe2O3 adhered on the surface of the modified ceramic. Biological deodorizations of hydrogen sulfide （HAS） were conducted by using bio- trickling filter with ceramic and modified ceramic as carrier. Bio-triekling filter using modified ceramic carrier had higher ability to remove He S because of higher microorganism adhesion capacity and a shorter bio-film forming time of modified ceramic. When the inlet H2 S between 124 and 4 396 mg/ma, the predominance was more significantly.
