1Anaerobic Removal of Trace Organic Contaminants in Sewage Sludge: 15 Years of Experience显示文摘Trace organic contaminants (TOCs) correspond to a broad range of molecules generated either directly or indirectly by human activity. Even though TOCs are found at low concentrations in the environment, they often accumulate by biomagnification and bioaccumulation into biological organisms and cause irreversible damages in biological systems through direct or indirect toxic effects such as endocrine disruption and tumour initiation. This manuscript presents the main findings of over fifteen years of research focusing on biological removal of various TOCs found in sewage sludge from urban treatment plants. A special focus of the research was made on microbial processes in complex anaerobic ecosystems. Four families of compounds mostly retrieved in urban plants were studied: the polycyclic aromatic hydrocarbons (PAHs), the polychlorobiphenyls (PCBs), the phthalic acid esters (PAEs), and the nonylphenol ethoxylates (NPEs). It was observed that the microbial capability for removing low amounts of TOCs required a long adaptation time and was often limited by the bioavailability of these compounds. In fact, the overall biodegradation resulted from the numerous interactions existing between the matrix (organic matter) and the microbial ecosystems according to the physico-chemical sorption properties of these compounds. Mechanistic aspects were also tackled in depth and specific models were developed for better understanding the network of interactions between TOCs, microorganisms, and organic matter. These findings could be extrapolated to other ecosystems such as soils and sediments. Finally, it was shown that microbial cometabolism was essential for TOC removal, and the concept of bioavailability was not only dependent on the nature, the level, and the sorption properties of TOCs but was also strongly dependent on the nature and the concentration of the sludge organic matter. Specific parameters were proposed for better evaluating the fate of TOCs in microbial anaerobic processes and technological solutions for efficient removal of these compounds were also proposed.M.

2侧吹气流方向对大功率CO_2激光焊缝成形的影响显示文摘激光深熔焊过程中会在熔池上方产生等离子体云,若该等离子体云过密,将降低激光入射到工件表面能量密度。在工业应用中,常采用侧吹辅助气体来减弱等离子体云的影响。本文通过试验,研究了在不同气体流量下。侧吹气体方向不同对焊接过程稳定性和焊缝成形的影响。结果发现:使用大功率CO_2激光焊接AH32时,侧吹气体方向对焊缝成形有着明显的影响。从熔池和等离子体两个方面,解释了侧吹气体方向的影响机制。李国华 贾时君 Douglas Steyer Kevin B Albaugh 吴毅雄 2007热加工工艺2007,36,19:7

4焊接用保护气体的最新进展和应用技术显示文摘在任何电弧焊过程中如果不加保护,大气中的氧气和其他气体会侵入电弧和熔池,与熔化的金属反应产生缺陷,影响焊接效果。焊接保护气的主要功能是保护熔化金属免受大气的污染。除了它的保护功能,每种焊接保护气都有其独特的性能,对焊接速度、焊缝熔深、焊缝成形、焊接烟尘、电弧稳定性及焊缝力学性能等产生相应的影响。Douglas Steyer 2004机械工人(热加工)2004,28,5:4
