中文摘要
该实验已经通过混合污泥处理过程的模拟数据与航空数据库进行了整合,以提高污泥处理过程的效率。该复合物,其中含有芽孢杆菌物种,被用作Aerobic Digestion的种子泥浆。从开始与过程组合的航空数据的污泥治疗性能与模拟数据作为预处理(航空-模拟数据过程)结合,并将该过程与模拟数据作为后处理(模拟数据-模拟数据过程)结合的航空数据作为模拟数据进行比较。下一个是对模拟-过程有效性的影响。要说的是,该复合材料被放入了模拟发酵污泥和种子污泥中,而航空发酵材料则被放入各种发酵温度(20 ° C、30 ° C、50 ° C)中。最后,航空数据被包含在各种基底中,以及一些芽孢杆菌基底(一种代表) ...

英文摘要
The experiment was carried out with the sludge treatment process of combining anaerobic digestion with aerobic digestion in order to improve the sludgy process efficiency. The compost that contained the Bacillus species was used as seed sludge of aerobic digestion. To begin with, the sludge treatment performance of the process combining aerobic digestion with anaerobic digestion as pretreatment (aerobic-anaerobic digestion process) and that of the process combining aerobic digestion with anaerobic digestion as posttreatment (anaerobic-aerobic digestion process) was compared. Next, the effect of aerobic digestion temperature of anaerobic -aerobic digestion process on the process efficiency was examined. That is to say, the compost was put into anaerobic digested sludge as seed sludge, and aerobic digestion was carried out at various digestion temperatures (20℃,30℃,50℃). Finally, aerobic digestion was carried out in various substrates, and whether Bacillus subtrlis (a kind of the represe … More ntative Bacillus species) existed in each aerobic digester was examined by FISH (fluorescent in situ hybridization) method.The following conclusion can be made :・Anaerobic-aerobic digestion process was more possible stabilized processing than aerobic-anaerobic digestion process.・The largest VSS degradation rate in aerobic digestion of anaerobic -aerobic digestion, process was 52% at 20℃,52 and 42% at 30℃ and 61% at 50℃. In addition, the overall VSS degradation rate through anaerobic -aerobic digestion process was over 80% at each digestion temperature. Still, the nitrification hardly happened in the operation except for 30℃.・In aerobic digestion of anaerobic-aerobic digestion process, the effect of digestion temperature could not be observed at the largest VSS decomposition rate in the operation for 3 days, the decomposition rate increased, as digestion temperature rises after the operation for 7 days.・It was possible to detect Bacillus subtilis only from the digester cultivated in the sucrose substrate.
