摘要
本文以处理生物制品废水的生产性四级转盘的生物膜为材料,在监测转盘对废水污染指标(BOD_5、COD_(cr)、挥发酚)降解性能的同时,测定了各级转盘生物膜的挥发性固体(VS)、活性微生物数目(AMN)以及TTC-脱氢酶活性(TTC-DHA)等活性参数,并分析讨论了VS、AMN、TTC-DHA与转盘级数的关系以及TTC-DHA与VS的相关性等问题。结果表明,TTC-DHA可能将会成为测定转盘生物膜活性的有效参数。
Active parameters such as Volatile Solid (VS), Active Microorganism Number (AMN) and TTC-Dehydrogenase Activity (TTC-DHA) of the biological film of a four-stage rotating biological contractor (RBC), which was used in the treatment of waste water from the production of bioproducts, was determined, while degradation characteristics of RBC for waste pollution targets (BOD5 COD and Volatile Phenols) being monitored. The relationship between VS, AMN and TTC-DHA and stages as well as the correlation between TTC-DHA and VS were also analysed and discussed. Results show that TTC-DHA would most probably become an efficient parameter in determining RBC biological film activities.
