摘要
采用接种普通好氧污泥和缺氧污泥处理中药难降解废水并进行小试试验,考察两种污泥对两相厌氧工艺快速启动的影响.结果表明：采用本中心开发的专利高效两相厌氧反应器,好氧污泥和缺氧污泥的启动几乎可以获得相同的启动速度,30 d以内就可实现快速启动;好氧污泥启动承受的负荷更高,抗冲击负荷能力更强（产甲烷相反应器在容积负荷为7～9 kgCOD/（m3·d）时,两相系统的总容积负荷为6～8 kgCOD/（m3·d）时,去除率都在90%以上）;扫描电镜照片表明好氧污泥启动的种群更丰富,生态结构更合理.建议处理高浓度难降解废水时以好氧污泥接种,既能够经济地实现快速启动又能在高负荷下稳定运行.
A laboratory - scale experiment was conducted fed with the wastewater from production of traditional Chinese medicine by seeding the anoxic and aerobic sludge. The experiments demonstrated that applying the patent and high - powered two - phase anaerobic reactors invented by our research center, almost the same speed of start - up could be achieved after seeding the anoxic and aerobic sludge. Rapid start - up can be realized within 30 days. The volume - loading rate which aerobic sludge start - up system can stand was higher than anoxic sludge start - up system. And the ability of resistance to the shock loading of aerobic sludge start -up system was higher, too. （The range of suitable volume -loading rate 7 -9 kgCOD/（ m^3 · d） at mathanogenic phase and 6- 8 kgCOD/（m^3 · d） at two anaerobic system, both COD removal were above 90% ）. Furthermore, from the scan electron microscope microorganism photos taken in two -phase anaerobic reactors, the richness of bacteria communities and suitable ecology structure of aerobic sludge start - up system were observed. Therefore it was suggested that aerobic sludge to seed reactors was more suitable to treat high strength refractory wastewater. In addition, it also could realize rapid start- up economically and stable running under high volume- loading rate.
