活性污泥耐盐降解邻氯苯酚特性及群落结构分析

采用SBR反应器驯化中度嗜盐菌为主的活性污泥,高效处理高盐邻氯苯酚(2-CP)废水。不同盐度的驯化结果表明,当NaCl质量浓度为10~80g/L时,2-CP和COD的去除率均达到91%。当NaCl质量浓度为80g/L,2-CP质量浓度在1000mg/L以上时,去除率可以维持在98%,反应器达到最佳处理效果。在此条件下,活性污泥胞外聚合物(EPS)的含量最高达到142.6mg/g。随着盐度升高,EPS中的多糖含量也随之增加。采用显微镜和扫描电镜(SEM)观察,发现在高盐条件下,活性污泥中大部分微生物呈现球状,且菌群有自发聚集的趋势。16SrRNA基因文库分析表明,产碱杆菌是污泥中的优势菌群,它属于变形菌门。PCR扩增和测序分析2-CP降解途径的关键酶基因,发现羟化酶、氯代邻苯二酚1,2-双加氧酶和氯代邻苯二酚2,3-双加氧酶同时存在于活性污泥系统中,表明该活性污泥可能具有多样的2-CP降解途径。

Acupuncture Treatment of Vomiting

CASE HISTORY A female patient, 46 years old, head of the foreign affairs department of a certain university in Beijing, paid her first visit on October 9, 2006, with the chief complaint of vomiting for one month. She got vomiting after meals in early September. Before that, she had discomfortable sensation in the stomach due to angry with others, but she didn't pay much attention. Later, it developed into vomiting after eating. After the vomiting, the discomfort would be relieved, but with slight hypodynamia. She was once diagnosed as having 'neurogenic vomiting'. Having taken some western and Chinese drugs, the above symptoms were a little bit improved, but she would have nausea upon eating and with regurgitation. Because of the fear for vomiting, she did not dare to have food intake, with body weight reduction of 6 kilos in one month.
