| 中文摘要 |
| 本研究选用三种不同性质的填料柱,以三种不同性质和不同浓度的废水进行对比试验,观察处理后的出水,结果表明:火山凝灰岩是一种优良的填料,由于火山岩孔隙多表面积大,接种菌种极易吸附在其粗糙的表面上,迅速生长繁殖,形成有效的生物过滤膜。该系统运转第14天,废水中TOC去除率达95%。 |
| 英文摘要 |
| The anaerobic filtration (AF) is the process in which organic matter is broken down under anaerobic comdition to methane and carbon dioxide. In the process, bacteria attach themselves quickly upon filter media and Absorb nutrient from the surrounding flow of influent. The stability of anaerobic filter depends on seed sludge, filter media and the condition of digester. Three kinds of the filter media and various wastewaters were used in this study. The result indicated that the pelelith filter can remove about 95% of TOC in wastewater only 14 days after it was set up. It is evident that if the AF process was controlled in a good condition, it will start up tnd get stability qpickly. |
