Removal characteristics of sulfamethazine （SMZ） by sludge and a bacterial strain using an aerobic sequence batch reactor （ASBR） were studied. Operating conditions were optimized by varying the reaction time and sludge retention time （SRT）. AnAchromobacter sp. （S-3） with the ability to remove SMZ was isolated from the ASBR. The effects of different operating parameters （pH and temperature） on the biodegradation of SMZ by S-3 were determined. The results indicate that, between 0.5 and 4 hr, reaction time of the ASBR had a significant effect on the SMZ removal efficiency in the system. The SMZ removal efficiency also increased from 45% to 80% when SRT was prolonged from 5 to 25 days, although longer SRT had no impact on SMZ removal. The SMZ adsorption rate decreased with increasing temperature, which fitted Freundiich isotherm well. The removal of SMZ in the ASBR was due to the combined effects of adsorption and degradation, and degradation played a leading role.

研究了不同水力停留时间(HRT)和污泥龄(SRT)条件下四环素(TC)和四环素耐药菌(tetracycline resistant bacteria,TRB)在AO工艺各池中的变化情况,并在最优工况下,用宏基因组16s DNA技术测定了各池微生物群落特征。结果表明,HRT的延长对TC的去除率影响不大,在90%左右。SRT从5 d延长到20 d时,TC的去除率从81.8%升高到90.9%。适当的延长HRT和SRT有利于减少TRB的数量。AO各池的四环素耐药菌优势菌属于Proteobacteria(变形菌门)和Bacteroidetes(拟杆菌门)。

膜蒸馏是一种逐渐兴起的热驱动膜技术,近年来在高盐废水的处理中受到了大量关注。然而,膜结垢是制约膜蒸馏工业化应用的瓶颈问题。通过向直接接触式膜蒸馏系统中引入脉冲流场来缓解硫酸钙结垢,分别探讨了脉冲时长与脉冲频率对抑制结垢效果的影响以及通量强化效果。结果表明,在脉冲时长为0.5 s,脉冲频率为5 min-1的最佳条件下,膜蒸馏通量在运行20 h后仍能达到初始通量的70%以上,并且通量强化比(FER)接近于1.3。实验结束后的膜表面形貌分析也表明,最佳脉冲条件下的膜表面结垢较少,仍能够清晰地观察到膜结构,而稳定流下的膜表面则有大量硫酸钙晶体堆积。这是因为,与稳定流条件相比,脉冲流能够促进硫酸钙的均相结晶,并利用形成的膜表面剪切力与膜振动将硫酸钙晶体去除。
