利用荧光原位杂交(FISH)和克隆文库构建技术,研究了厌氧污泥床反应器处理含酚废水时所收获的颗粒的微生物群落结构。研究发现,互营杆菌(Syntrophorhabdaceae)和隐杆厌氧菌(Cryptanaerobacter)的克隆是苯酚降解的主要原因。为了准确地对隐杆厌氧菌的克隆进行分类归属,需要利用近全长的16S核糖体RNA(rRNA)基因序列进行进化分析。设计了三种寡核苷酸探针用于检测以下三个分类群:互营杆菌、隐杆厌氧菌和互养菌。对厌氧颗粒薄片的FISH 分析显示细菌和古菌呈随机分布。然而,互营杆菌、隐杆厌氧菌和互养菌分布明确。在颗粒细胞的外层发现了隐杆厌氧菌和互养菌,两者关系密切,而互营杆菌则位于颗粒细胞的深层。细菌之间的代谢联系和对底物的亲和力很可能是造成这种特殊分布的原因。研究人员观察到颗粒污泥中苯酚的降解主要通过以下方式进行:首先,隐杆厌氧菌将苯酚转化为苯甲酸盐,然后被互养菌降解为乙酸盐。苯酚的这种互饲降解发生在颗粒表面附近,此处苯酚浓度较高。在苯酚浓度较低的颗粒深部,互营杆菌将苯酚降解为乙酸盐。结果表明,互营杆菌不太可能产生苯甲酸盐,并将其作为中间产物来喂养邻近的生物,这一点与以往研究所提出的理论相矛盾。

High strength sugar refinery wastewater was treated in a mesophilic UASB. Pyrosequencing reveals microbial community succession with OLR increase. Diversity of microbial communities in OLR12 is much higher than those in OLR36 and OLR54.0 kgCOD/(kg VSS·d). Fermentative bacteria could deal with increasing OLR through the increase of microbial diversity and quantity. Hydrogen-producing acotogens and methanogens mainly coped with high OLR shocks by increasing the quantity of community

An innovative and efficient design of solar receivers/reactors can enhance the production of clean fuels via concentrated solar energy. This study presents a new jet-type burner nozzle for gaseous feedstock injection into a cavity solar receiver inspired from the combustion technology. The nozzle design was adapted from a combustion burner and successfully implemented into a solar receiver and studied the influence of the nozzle design on the fluid mixing and temperature distribution inside the solar receiver using a 7 kW solar simulator and nitrogen as working fluid. Finally, a thorough computational fluid dynamics (CFD) analysis was performed and validated against the experimental results. The CFD results showed a variation of the gas flow pattern and gas mixing after the burner nozzle adaptation, which resulted an intense effect on the heat transfer inside the solar receiver.
关键词: solar reactor nozzle CFD heat transfer mixing and recirculation

考虑到人口众多,经济快速发展,人民生活水平不断提高,人均能源相对贫乏和环境保护,国家已决策加快核能应用的发展。采用压水堆-快堆匹配闭式燃料循环达到核能供应的快速增长和可持续性的基本战略已经决定,也决定了分离和用快堆和ADS对高放废物(MA)的嬗变战略。笔者建议快堆工程发展将分三步进行,中国实验快堆(CEFR,65 MWt/20 MWe),中国原型/示范快堆(CEFR/CDFR,大于等于1 500 MWt/600 MWe)和中国经济验证性快增殖堆(CDFBR,1 000 MWt/1 500 MWe)。CPFR的设计研究已于2006年开始目前正处于安装、调试阶段,计划2009年首次临界。近期讨论建造比600 MWeCPFR更大功率的堆作为CDFR,以加速快堆商用的步伐。
