一、前言随着电力工业的不断发展,排入大气环境的烟尘越来越多。我国环境工作者研究表明,目前我国大气中以尘的污染为主,烟尘是城市大气污染中的主要污染物之一,我国近期环保工作的重点是解决大气中尘的污染。解决这个问题,首先是应了解和研究各地大气中颗粒物(即气溶胶)的浓度和粒度分布规律。在新建、扩建电厂的环境予评价中,须粒物的影响预测也是评价中的主要内容之一。 相似文献

从六十年代开始,国外兴起了一门新学科——风工程,在欧洲称为工业空气动力学。它是以流体力学、空气动力学、气象学、结构力学及生理学为理论基础,处理大气边界层中风和地面上活动着的人们及他们的工作之间关系的一门学科。早期主要应用于大气扩散、污染物的大气传输、风对结构的作用等领域中。近年来,它的应用研究已深入到了各行各业,例如结构设计、环境质量评 相似文献

Urban Air Quality Management Systems are software tools that combine air quality models with various software modules like geographical information systems, databases, expert systems and statistical analysis tools. Such systems try to interpret as accurately as possible the complex interactions between various atmospheric, emission, land use and topographic parameters involved in the air pollution management problem, in order to provide support for environmental strategic planning and decision making. As this process involves a huge set of parameters, some of which may only be roughly estimated, air quality management systems tend to aggregate parameters in order to simplify their analysis and make it more effective and operational. Yet, this aggregation may lead to deviations in the analysis results, as proved in this theoretical article, and thus influence the decision making and strategic planning process. According to the findings of this article, such a policy making process should focus primarily on short term measures when dealing with air pollution episode management. 相似文献

Due to the presence of toxic metals, dumping of heavy oil fly ash (HOFA) is causing ever-growing environmental problem including the pollution of air, water and soil. The present study investigates the possible environmental impacts associated with the land disposal of HOFA generated in the power plant. Different modeling and laboratory analysis were integrated to address the real environmental problems. Leaching behavior of heavy metals within the HOFA were investigated by laboratory batch leaching tests, which confirmed that most of the toxic elements in the HOFA can easily leach into the environment with rain water. The level of atmospheric dust surrounding a HOFA dumping site was predicted using the Industrial Source Complex (ISC3) air dispersion model, and the results indicated that the dumping of HOFA could be a potential hazard for local air quality. The study also revealed different reuse options of HOFA. The characteristic analysis confirmed HOFA can be used as a natural adsorbent to remove pollutants from wastewater or as soil stabilizing material by blending with cement. 相似文献

Integrated environmental management in urban areas is nowadaysconsidered a sine qua non objective of Community and nationalenvironmental and development policies. A large amount ofscientific information on the state of the environment is nowavailable from a large pool of data sources. This work presentsan innovative method for integration of these data sources andeffective coupling of environmental information with appropriatemodels and decision-support tools. State-of-the-art Earthobservation techniques, ground-based air quality measurements,atmospheric transport and chemical modelling, and multi-criteriadecision-aid systems are used in an integrated information fusionenvironment in support of environmental and health impactassessment and decision-making at the urban and regional scales. Results of the pilot application of the method in the area ofLombardy in Northern Italy demonstrate the validity andusefulness of this novel approach. 相似文献
