5. General layout analysis
The general layout of the project is based on the principles of simplicity and convenience. The project has 1 entrance and exit, located on the south side of the project, facing the planned road, which is convenient for the transportation of raw materials and finished products; the project office and living building is located on the left side of the entrance and exit, which is convenient for people to enter and exit; the production workshop is located in the middle of the plant plot, and the batching warehouse is located in the northeast of the plot angle. It can be seen that each department of the project is set up compactly to facilitate the transfer of logistics.
The process dust exhaust cylinder after the project treatment is set on the top floor of the production workshop. The project office area is located in the side wind direction of the dust and waste gas pollution source. A certain greening is set in the factory. When beautifying the plant landscape, it can purify the air, insulate and reduce noise effect. In general, the layout of the project is basically reasonable.
6. Conclusion of environmental impact during construction period
The ecological environmental impact during the construction period of the project is mainly manifested in the impact of soil erosion caused by soil loosening. However, the impact during the construction period is partial and short-term, and will not cause long-term impact on the surrounding ecological environment. With the end of the construction period, the construction site will be covered by cement, buildings and vegetation, which will help eliminate the adverse effects of soil erosion.
During the construction period, the operation of various construction machinery and transportation vehicles will generate exhaust gas, dust, waste water, noise, solid waste, and domestic sewage and domestic garbage of construction personnel. These pollutants will constitute the surrounding environment Different degrees of pollution impact. After taking corresponding environmental protection measures, the environmental impact can be minimized, and the construction of the project has little impact on the surrounding environment. The environmental impact during the construction period is temporary and disappears immediately after the completion of the construction.
