高氯酸钾项目生产过程中的环境风险及防范措施

根据国家环保总局发布的"高污染、高环境风险"产品名录(2009年),无机盐产品高氯酸钾属于高环境风险的产品,其生产存在较大风险。高氯酸钾项目在生产过程中的环境风险主要来源于强酸、强碱、有毒有害、易燃易爆等原辅材料、产品,运输、贮存和使用过程产生的燃爆、泄漏、贮运风险以及工艺废气治理措施失效等环节。识别项目产生的环境风险主要包括爆炸风险、泄漏风险、危险化学品贮运风险及氯气直排风险,并从生产管理、生产工艺及贮运等方面提出相应的防范措施。     

Mapping Biological Resources in the Coastal Zone: An Evaluation of Methods in a Pioneering Study from Norway

For many years, the planning and management of terrestrial areas has been supported by a detailed knowledge of the distribution of habitats and their associated species. However, the detailed mapping of biological resources in extent coastal areas, such as the Norwegian coastal zone, is unrealistic due to its enormous coastline. Here, we present a useful and feasible approach and a set of simple, cost-effective methods which are suitable for providing a broad-scale overview of marine habitats and fish resources. This approach was developed in conjunction with a pioneer study conducted along the southern coast of the Skagerrak, where we combined knowledge gathered from local fishermen with scientific knowledge of important species and nature types to establish a coastal sea mapping program. GIS modeling tools were used in both the mapping program and to integrate local and scientific knowledge into digital maps made available to local area management. This multi-faceted approach, which combines local knowledge and scientific methods, provides valuable information with respect to marine biodiversity, and has been used extensively by local environmental management.     

火电厂电除尘器电控系统的节能改造

电除尘器是火力发电厂的高能耗设备,从细节入手,挖掘电除尘器节能潜力,利用原有设备进行改造,采用简易脉冲供电方式和临界反电晕供电方式可以提高电除尘器电能的利用率,大幅度地降低电除尘器的能耗,实现节能。通过对电除尘器电控系统改造实例的前后电场参数进行比较,说明这种改造方法是可行的,实现了经济、节能与环保三者的兼顾与统一。

涞源县生态县建设的思考

生态县建设指标包含三部分,即经济发展、生态环境保护、社会进步。这三个指标的完成需要政府、企业、公民的共同参与。经济实力弱、发展水平和科技水平较低、生态环境意识差、环境及资源承载能力较低、环境综合治理缺少投入等因素严重制约了涞源县的生态县建设。只有强化组织领导,建立目标责任机制,编制生态县建设规划,重点推动经济现代化建设,加强环境基础设施建设,加强宣传教育,鼓励全民参与生态县建设,才能加快涞源县生态县建设的步伐,最终实现人与自然和谐发展。     

对我国环境行政复议制度的几点思考

现行环境行政复议制度存在的一些不足,阻碍了其在促进环保部门依法行政、维护群众合法环境权益方面作用的发挥,应当扩大享有环境行政复议申请资格的人员范围,规定环境行政复议简易程序,增强复议机构的独立性和提高复议工作人员的综合素质。     

高校节能管理初探

目前,低碳生活的方式和理念已渗透到各高校大学生的学习和生活中,这为高校的节能管理创造了良好的基础和条件。倡导节约资源之风,尽节约能源之责,是建设生态文明社会的一项紧迫任务。因而,提高节能意识、完善节能管理体制、科学使用节能设备、加强节能队伍建设等措施必将促进高校节能管理工作的顺利开展。     

完善公众参与环境决策机制的法制探讨

公众参与环境决策是一项重要的公众民主权利。我国已经将环境公众参与作为一项重要的环境保护法律制度,但是由于目前我国环保法律制度的不完善,在实施公众参与环境决策机制上存在着诸多问题,本文从法制的角度探讨了公众参与环境决策的理论依据,分析和论证建立适合我国国情的公众参与环境决策制度的主要方式,并提出完善公众参与环境决策制度的建议。     

Reclaimed Mineland Curve Number Response to Temporal Distribution of Rainfall1

Warner, Richard C., Carmen T. Agouridis, Page T. Vingralek, and Alex W. Fogle, 2010. Reclaimed Mineland Curve Number Response to Temporal Distribution of Rainfall. Journal of the American Water Resources Association (JAWRA) 46(4): 724-732. DOI: 10.1111/j.1752-1688.2010.00444.x Abstract: The curve number (CN) method is a common technique to estimate runoff volume, and it is widely used in coal mining operations such as those in the Appalachian region of Kentucky. However, very little CN data are available for watersheds disturbed by surface mining and then reclaimed using traditional techniques. Furthermore, as the CN method does not readily account for variations in infiltration rates due to varying rainfall distributions, the selection of a single CN value to encompass all temporal rainfall distributions could lead engineers to substantially under- or over-size water detention structures used in mining operations or other land uses such as development. Using rainfall and runoff data from a surface coal mine located in the Cumberland Plateau of eastern Kentucky, CNs were computed for conventionally reclaimed lands. The effects of temporal rainfall distributions on CNs was also examined by classifying storms as intense, steady, multi-interval intense, or multi-interval steady. Results indicate that CNs for such reclaimed lands ranged from 62 to 94 with a mean value of 85. Temporal rainfall distributions were also shown to significantly affect CN values with intense storms having significantly higher CNs than multi-interval storms. These results indicate that a period of recovery is present between rainfall bursts of a multi-interval storm that allows depressional storage and infiltration rates to rebound.
