| With the introduction of a wide range of environmental approach and the legal system, the construction of the project's environmental impact assessment prior to the growing importance of work, but there are still a lot of the managers of construction projects valued only the economic interests of their own businesses, lack of social responsibility, do not attach importance to the project's environmental impact assessment work, and even lead to some of the projects completed, as a result of too much environmental pollution, and not an appropriate control measures can not be running into.In this paper, the application of multi-disciplinary knowledge, in accordance with the theory and practice, a combination of quantitative and qualitative principles, based on engineering analysis in the light of Shandong Haihua Co., Ltd. of 100,000 tons / year PVC project, focusing on projects on the environment from air quality and environmental impact of risk on. In this paper, collected a large amount of basic data, and classify these data integration, logical manner in accordance with and by selecting the appropriate mathematical methods, data analysis of the parties concerned, which is able to draw relevant conclusions also be able to demonstrate logical reasoning to close this paper, the Its aim is to draw attention to the investment side, from the problem at its source, prevention and mitigation of accidents and reduce accidents on the surrounding environment and human health hazards.In this paper, the innovation is no longer a general discussion of the environmental impact of the project, but from an environmental impact assessment in the targeted selection of the most important points discussed in detail, this model can help address the investment in construction projects have been formally to have a clear understanding before the project may have on the environment the most severely affected, resulting in the design phase of the drawings will be able to take effective measures to reduce or avoid the project after the completion of the pollution of the environment has a certain reference value. |
