拆除大型建筑物过程粉尘污染扩散特征分析及防治研究
|
摘要
建筑施工过程产生的大量粉尘,是现代城市大气污染的重要污染源之一。建筑粉尘的大面积扩散,不仅会对大气生态环境造成严重破坏,还会对人们的身体健康产生严重影响,必须通过相应理论体系和分析技术,详细探究粉尘污染扩散特征和防治手段。利用Fluent程序运行结构,引入计算流体力学数据和工程粉尘运行轨迹动态数据计算,建立Fluent湍流动态分析模型,对拆除大型建筑物过程中粉尘污染扩散特征进行动态模拟分析;基于大气对环境影响理论和Fluent湍流动态分析模型对粉尘污染的扩散分析数据,提出了以加强管理施工单位施工规范、市民参与施工粉尘监督和治理、政府完善治理标准和经济手段等方式为核心的全民性多方向粉尘污染防治管理措施。
Dust pollution caused by construction is one of the important pollution sources of modern air pollution. Widespread diffusion of dust pollution can cause serious damage to ecological environment atmosphere, also has a serious impact on people's health. It must be tapped through the corresponding theoretical system and analysis technology, detailed exploration dust pollution diffusion characteristics and methods of prevention and control. Through the analysis of the microstructure composition of pollution dust, the influence of dust pollution on the atmosphere environment is summarized in detail. Fluent software program is run by the introduction of computational fluid dynamics data and dynamic data calculation, construction dust orbit Fluent turbulence dynamic analysis model is established, the dust pollution diffusion characteristics in the process of demolition of large buildings for dynamic simulation analysis; Based on the theory of atmospheric environmental impact and Fluent turbulence dynamic analysis model for the spread of the dust pollution data, put forward to catch dust pollution education opportunity, the citizens to participate in the construction supervision and management, improve the management standard and economic means to nationwide as the core of dust pollution prevention and control of management measures. To test the true effectiveness of related management way, to Shenyang in our country as the object, through the dust content in Shenyang atmosphere and pneumoconiosis disease quantity change trend, the comparison test.
