构建了基于层次分析法(AHP)和标杆法(BM)的水污染控制技术混合评估模型,并以石化废水达标排放处理技术为例,确定了包含3项一级指标、8项二级指标和14项三级指标的评估指标体系和指标权重。以5种典型石化废水达标排放处理技术工艺为评估对象,获得技术、经济、环境单项评估指数和综合评估指数。评估结果表明,“隔油+气浮+A/O-PACT”和“隔油+气浮+MBBR+催化臭氧氧化+BAF”两种技术工艺综合指数较高。实际应用时,还应根据工程实际情况对指标权重进行调整,因地制宜地选择合适的废水达标排放处理技术工艺。 相似文献

The National Research Council's report, Innovations in Ground Water and Soil Cleanup: From Concept to Commercialization, reviewed the implementation of innovative remediation technologies and portrayed a bleak outlook for them. Conversely, Terra-Kleen has invented, patented, permitted, and profited through the use of an innovative technology in the current market. Terra-Kleen has implemented a solvent extraction technology for the removal of PCBs, PAHs, and chlorinated pesticides from soil, sediment, and debris. To date, Terra-Kleen has successfully processed over 23 million pounds of PCB-contaminated soil in Alaska, California, Florida, Ohio, and Oklahoma. The company has been profitable each year since its inception, and has averaged a revenue growth rate of 94 percent per year for the last four years. Corporate growth has been financed entirely through profits and conventional bank loans at favorable interest rates. This article reviews the factors that have led to Terra-Kleen's success, overviews the solvent extraction technology, and details specific projects that have implemented the technology. 相似文献

Reactive walls containing metallic iron have been installed at several commercial sites in the United States to degrade chlorinated organic compounds in groundwater. Although the results of laboratory studies conducted to determine reaction mechanisms have been widely disseminated, little information has been published on the full-scale application of this technology. This article describes the construction, implementation, and cost of in-situ reactive walls at three commercial sites. 相似文献

Nanotechnology application to contaminated site remediation, and especially the use of nanoscale zero‐valent iron particles to treat volatile organic compound (VOC)‐impacted groundwater, is now recognized as a promising solution for cost‐effective in situ treatment. Results obtained during numerous pilot tests undertaken by Golder Associates between 2003 and 2005 in North America (United States and Canada) and Europe have been used to present a synthetic cross‐comparison of technology dynamics. The importance of a comprehensive understanding of the site‐specific geological, hydrogeological, and geochemical conditions, the selection of appropriate nanoscale particles, the importance of monitoring geochemical parameters during technology application, and the potential of nanoparticle impact on microbial activity are discussed in this article. The variable technology dynamics obtained during six pilot tests (selected among numerous other tests) are then presented and discussed. © 2006 Wiley Periodicals, Inc. 相似文献

Landfill bioreactor technology offers important advantages in the management and treatment of municipal solid waste, including accelerated waste stabilization rates, enhanced gas production, facilitated leachate management, volume reduction andminimized long-term liability. These advantages have been documented in laboratory- , pilot- and full-scale investigations. Although challenges remain in implementing the technology, bioreactor landfills are designed and operated with increasing frequency. 相似文献

Ionic Liquids as Environmentally Friendly Solvents in Macromolecules Chemistry and Technology,Part I
With the increasing emphasis on the environment and the need to find environmentally friendly solvent systems, ionic liquids
(IL)s have been emerging as promising green solvents to replace conventional solvents in recent years. They possess unique
properties such as nonvolatility, low toxicity, ease of handling, nonflammability and high ionic conductivity; thus they have
received much attention as green media for various chemistry processes. This report provides an extensive overview of use
of ILs in polymers chemistry and technology. 相似文献
