水解-酸化-好氧工艺处理染料废水的应用

介绍了水解-酸化-好氧工艺处理染料生产废水。长期运行结果表明，当染料生产废水的COD质量浓度〈2000mg．L^-1时，在水解反应器、酸化反应器和曝气池的水力停留时间（HRD分别为7．0，7．0和6．0h的条件下，出水可以达到国家二级排放标准。水解-酸化过程提高了染料生产废水的可生化性，为后续好氧处理创造了条件。

对建设项目环境保护公众参与机制的几点思考

公众参与是一种独特的管理职能.公众不仅要参加建设项目的环境保护,而且要参加可能对环境造成影响的规划项目的环境保护.建设项目环境信息公开化是公众参与的基础,应健全政府与建设单位、公众环境信息公开化的平台,坚持"谁主管,谁负责"的原则,充分发挥社区作用,不断完善建设项目环境保护公众参与机制.

南黄海鳀鱼产卵场大型底栖生物次级生产力研究

根据2001至2003年南黄海鳀鱼产卵期在鳀鱼产卵场33个站考察采集的大型底栖生物定量样品资料,利用Brey's(1990)的经验公式对调查海区进行了大型底栖生物栖息密度、生物量、次级生产力和P/B值的研究计算.结果表明,该海域大型底栖生物平均栖息密度为194.3 ind.m-2,平均生物量以去灰干重计,为4.08 g m-2,平均次级生产力以去灰干重计,为4.09 g m-2a-1.研究表明,生物量和次级生产力受水深的影响.平均P/B值在研究海域为1.32a-1.对研究结果与整个南黄海、渤海和东海的结果进行了比较与讨论,证明生产力随水深的加大而降低,P/B值随水温升高而升高.图2表1参25     

Is big the best? Queen size,usurpation and nest closure in a primitively eusocial sweat bee (<Emphasis Type="Italic">Lasioglossum malachurum</Emphasis>)

For primitively eusocial insects in which a single foundress establishes a nest at the start of the colony cycle, the solitary provisioning phase before first worker emergence represents a risky period when other, nestless foundresses may attempt to usurp the nest. In the primitively eusocial sweat bee Lasioglossum malachurum (Hymenoptera, Halictidae), spring foundresses compete for nests which are dug into hard soil. Nest-searching foundresses (‘floaters’) frequently inspected nests during this solitary phase and thereby exerted a usurpation pressure on resident queens. Usurpation has been hypothesised to increase across the solitary provisioning phase and favour closure of nests at an aggregation, marking the termination of the solitary provisioning phase by foundresses, before worker emergence. However, our experimental and observational data suggest that usurpation pressure may remain constant or even decrease across the solitary provisioning phase and therefore cannot explain nest closure before first worker emergence. Levels of aggression during encounters between residents and floaters were surprisingly low (9% of encounters across 2 years), and the outcome of confrontations was in favour of residents (resident maintains residency in 94% of encounters across 2 years). Residents were significantly larger than floaters. However, the relationship between queen size and offspring production, though positive, was not statistically significant. Size therefore seems to confer a considerable advantage to a queen during the solitary provisioning phase in terms of nest residency, but its importance in terms of worker production appears marginal. Factors other than intraspecific usurpation need to be invoked to explain the break in provisioning activity of a foundress before first worker emergence.
