摘要
o -Nitrobenzaldehyde manufacturing wastewater is characterized for being highly saline, with its TN content and dissolved organic concentrations giving rise to high COD loads. A sequencing batch reactor was established to investigate the effects of major processing variables, such as SRT and HRT, on system performance. The optimal COD (86%) and TN (40.9%) removal efficiencies were obtained at 16 d (SRT) and 12 h (HRT). Design equations were developed by applying experimental data. Changes in sludge flocs were studied using a combination of methods including: chemical analysis; fluorescence in situ hybridization (FISH); and denaturing gradient gel electrophoresis profile analysis of 16S rRNA genes. Dramatic changes occurred during adaptation and β - Proteobacteria was found to be the most prevalent population. Besides, some species affiliated with α -subclasses of Proteobacteria and Cytophaga-Flavobacterium-Bacteroides (CFB) group were also enriched. This study may help with future research in providing a better understanding of the activated sludge biotreatment.

研究解析活性污泥处理废水过程中系列变化

日前，从世界著名学术期刊《生物资源技术》（Bioresource Technology）传来消息，浙江农林大学环境科技101班学生刘畅作为第一作者撰写的研究论文Biotreatment of o-nitrobenzaldehyde manufacturing wastewater and changes in activated sludge flocs in a sequencing batch reactor（《邻硝基苯甲醛合成废水生物处理及其处理过程中活性污泥相的变化研究》），被该刊物录用并发表在2012年1月总第104期上。

Bioresource Technology不仅是被SCI收录的著名期刊，更是世界权威的生物能源学术期刊，该杂志在2011年公布的JCR（《期刊引用报告》）分区中，位居工程技术类一区，2010年影响因子达4.365，很多学者专家都以在该刊物发表论文为荣，普通本科生在上面发表论文更是难上加难。

刘畅介绍说，该论文是她和同学们一起，在环境科学与工程学科虞方伯老师的指导下，根据从大一就开始进行的一项研究发表的重要成果。该项目所研究的，是由微生物组成的活性污泥，在处理含有邻硝基苯甲醛的废水过程中的一系列变化。（来源：中国科学报陈胜伟）
