The environmental impact assessment refers to the analysis , prediction and assessment of the potential environmental impact in the planning and construction of the project implementation , the proposed policies and measures to prevent or mitigate adverse environmental impacts , tracking and monitoring method and system . Two levels from the theoretical and empirical , Rohm Co., Ltd. of Japan the environmental impact of the project in the Tianjin Economic and Technological Development Zone Electronic Engineering . First , determine the project evaluation grade , the contents of the evaluation , the evaluation of the implementation of standards , as well as evaluating the scope of the environmental impact assessment and from the air, water , sound and solid waste . Atmospheric pollution factor to determine the target value , calculating the evaluation index and pollution -sharing rate , the project process emission point source Gaussian diffusion model and daily averages calculated model calculations in different stability , atmospheric environment under different wind speed combination . Production according to the project to take the sewage treatment process wastewater , domestic wastewater discharge standards of feasibility studies , the use of the noise from the decay mode , and the noise overlay mode , the prediction of the acoustic environment . Solid waste generated by the project from different angles , clean production , public participation , environmental and economic benefits and environmental risk analysis . Finally, this project pollutant emissions , pollution control measures , the environmental impact of the scope and extent of the construction project environmental feasibility , environmental protection measures , put forward opinions and suggestions
