医疗废物处置工程多技术方案综合评价系统研究及其辅助软件设计

针对医疗废物处置工程技术方案的选择问题,在综合分析医疗废物处置工程技术方案选择的影响因素和医疗废物处置技术特点的基础上,结合层次分析法和Delphi法,提出了一套综合评价指标体系及方法.选取技术性能、经济性、环境影响和社会制约因素等4个方面共24项指标,形成了初步综合评价指标体系,并建立了综合评价层次分析模型.由于涉及的数据量大且计算复杂,开发了相应的医疗废物处置工程技术方案综合评价系统的辅助应用软件.     

Present status and changes of the phytoplankton community after invasion of Neosalanx taihuensis since 1982 in a deep oligotrophic plateau lake, Lake Fuxian in the subtropical China

Phytoplankton assemblages in the subtrophical oligotrophic Lake Fuxian, the second deepest lake in China, were investigated monthly from September 2002 to August 2003. A total of 113 species belonging to seven phyla were identified, among them, a filamentous green alga, Mougeotia sp., dominated almost throughout the study period and comprised most of the total phytoplankton biomass.Mougeotia sp. has made a substantial development during the past decades: it was absent in 1957, only occasionally present in 1983,increased substantially in 1993, and became predominant in 2002--2003. It is likely that natural invasion of the Taihu Lake noodlefish (Neosalanx taihuensis) has led to a change of dominant herbivorous zooplankton from small to large calanoid, which has increased grazing pressure on small edible algae, and thus has indirectly favored the development of the inedible filamentous Mougeotia sp.     

洗涤剂磷对日本三角涡虫生长的影响

观察了含磷量不同的洗衣粉溶液对日本三角涡虫生长的影响。结果表明:无论洗衣粉含磷量高低对日本三角涡虫生长均有毒害影响,且高磷洗衣粉对涡虫的毒害远大于低磷洗衣粉,磷量的增加与涡虫死亡率呈正相关。实验中,自来水对照组对涡虫生长无影响。     

大孔强碱阴树脂去除饮用水中微量有机物

比较了大孔强碱阴树脂和颗粒活性炭在饮用水的深度处理中对有机物的去除效果。结果表明：(1)大孔强碱阴树脂的吸附容量比颗粒活性炭的大。在pH为8时,大孔强碱阴树脂对TOC的去除率最高。pH6～8时,对TOC的去除率没有明显的区别,而颗粒活性炭在pH为2时。对TOC的去除率最高;水温低能提高2种吸附材料的吸附容量。(2)在动态实验条件下。当流速相同,大孔强碱阴树脂的穿透时间明显比颗粒活性炭的长,大孔强碱阴树脂的制水量约是吸附床的10000倍。而颗粒活性炭却只有吸附床的4000倍。在饮用水的深度处理中,大孔强碱阴树脂可作为活性炭的最佳替代品。     

基于QuickBird卫星影像的徐径镇城市景观格局分析

以2000年和2004年的QuickBird卫星影像解译的徐径镇土地利用类型图为基础，对土地利用类型变化的幅度和土地利用类型之间转换的空间关系进行了研究，同时选取合适的景观格局指数对该区域的景观格局进行了分析。最后，给出结论和建议。     

Detection of Escherichia coli in wastewater based on enzyme immunoassay

This research describes a fast detection method on the basis of enzyme-linked immunosorbent assay (ELISA) for Escherichia coli in drainage of wastewater treatment plants. Optimized conditions such as the reaction format (sandwich or direct), the concentrations of diluted horseradish peroxidase (HRP)-E. coli conjugate, and anti-HPR antibody and pretreatment of E. coli were studied. Those results showed that the linear range of detection for E. coli was 10 cfu/mL-6 × 10⁴ cfu/mL. Compared with conventional methods, it is a convenient and sensitive detection method with low cost.
