  • Physics and chemistry of plasma Pollution Control Technology
    Plasma Sources Science and Technology, 2008
    Co-Authors: Jen-shih Chang
    Abstract:

    Gaseous Pollution Control technologies for acid gases (NOx, SOx, etc), volatile organic compounds, greenhouse gases, ozone layer depleting substances, etc have been commercialized based on catalysis, incineration and adsorption methods. However, non-thermal plasma techniques based on electron beams and corona discharges are becoming significant due to advantages such as lower costs, higher removal efficiency and smaller space volume. In order to commercialize this new Technology, the Pollution gas removal rate, energy efficiency of removal, pressure drop of reactors and useable by-product production rates must be improved and identification of major fundamental processes and optimizations of reactor and power supply for an integrated system must be investigated. In this work, the chemistry and physics of plasma Pollution Control are discussed and the limitation of this type of plasma is outlined based on the plasma parameters.

  • Recent development of plasma Pollution Control Technology: a critical review
    Science and Technology of Advanced Materials, 2001
    Co-Authors: Jen-shih Chang
    Abstract:

    Gaseous Pollution Control, solid and liquid waste treatments have been commercialized based on incineration, catalysis, adsorption, disposal with landfill, etc. More recently Technology based on plasmas has become significant due to the advantages such as lower costs, higher treatment and energy efficiencies, smaller space volume, etc. In order to commercialize this new Technology, the treatment rate, energy efficiency of treatment, pressure drop of reactor, reusable by-products production rate, must be improved, based on the identifications of major fundamental mechanism of processes, optimizations of reactor, and power supply for an integrated system. In this work, recent development of plasma Pollution Control Technology was critically reviewed and the principle of processes and reactor technologies were outlined. Special attention will be focused on material processing generated pollutants.

  • the current state of water quality and Technology development for water Pollution Control in china
    Critical Reviews in Environmental Science and Technology, 2010
    Co-Authors: Maohong Fan
    Abstract:

    This paper summarizes and presents an overview of the current state of water Pollution, as well as recent progress and the potential future development of water Pollution Control Technology, in China. Although China has made significant strides in water environmental protection over the past decades, analysis reveals that water Pollution in the nation is still not sufficiently Controlled, with a number of surface waters currently suffering varying degrees of Pollution. High nitrogen and phosphorous concentrations in many great lakes have caused eutrophication problems, and the frequency of blue algal bloom has increased. Likewise, river Pollution has not been effectively Controlled. Nitrogen, phosphorous, organic compounds, and heavy metals are ubiquitous in China's rivers, with up to 80% of urban rivers contaminated to varying degrees—a situation that continues to deteriorate. Next, eutrophication has occurred in many large reservoirs, with numerous toxic substances negatively affecting water quality. Fi...

  • Impact of photocatalytic remediation of pollutants on urban air quality
    Frontiers of Environmental Science & Engineering, 2016
    Co-Authors: Christian George, Anne Beeldens, Fotios Barmpas, Jean-françois Doussin, Giuseppe Manganelli, Hartmut Herrmann, Jörg Kleffmann, Abdelwahid Mellouki
    Abstract:

    In the recent years, photocatalytic self-cleaning and “depolluting” materials have been suggested as a remediation Technology mainly for NO_ x and aromatic VOCs in urban areas. A number of products incorporating the aforementioned Technology have been made commercially available with the aim to improve urban air quality. These commercial products are based on the photocatalytic properties of a thin layer of TiO_2 at the surface of the material (such as glass, pavement, etc.) or embedded in paints or concrete. The use of TiO_2 photocatalysts as an emerging air Pollution Control Technology has been reported in many locations worldwide. However, up to now, the effectiveness measured in situ and the expected positive impact on air quality of this relatively new Technology has only been demonstrated in a limited manner. Assessing and demonstrating the effectiveness of these depolluting techniques in real scale applications aims to create a real added value, in terms of policy making (i.e., implementing air quality strategies) and economics (by providing a demonstration of the actual performance of a new technique).

  • water Pollution Control Technology and strategy for river lake systems a case study in gehu lake and taige canal
    Ecotoxicology, 2011
    Co-Authors: Yimin Zhang, Yongchun Zhang, Yuexiang Gao, Houhu Zhang, Jianying Cao, Jinbang Cai, Xiangji Kong
    Abstract:

    The Taoge water system is located in the upstream of Taihu Lake basin and is characterized by its multi-connected rivers and lakes. In this paper, current analyses of hydrology, hydrodynamics and water Pollution of Gehu Lake and Taige Canal are presented. Several technologies are proposed for Pollution prevention and Control, and water environmental protection in the Taihu Lake basin. These included water Pollution Control integration Technology for the water systems of Gehu Lake, Taige Canal and Caoqiao River. Additionally, river–lake water quality and quantity regulation Technology, ecological restoration Technology for polluted and degraded water bodies, and water environmental integration management and optimization strategies were also examined. The main objectives of these strategies are to: (a) improve environmental quality of relative water bodies, prevent pollutants from entering Gehu Lake and Taige Canal, and ensure that the clean water after the pre-treatment through Gehu Lake is not polluted before entering the Taihu Lake through Taige Canal; (b) stably and efficiently intercept and decrease the Pollution load entering the lake through enhancing the river outlet ecological system structure function and water self-purifying capacity, and (c) designate Gehu Lake as a regulation system for water quality and water quantity in the Taoge water system and thus guarantee the improvement of the water quality of the inflow into Taihu Lake.
