The site selection of ventilation muffler of chemical industry construction project should conform to the local overall planning and industrial orientation, and should meet the requirements of environmental impact assessment of regional planning, and select appropriate industrial park. In the process of site selection, we should combine the natural environment and social environment of the construction area, as well as the nature, scale and emission characteristics of the proposed site selection area, and conduct a comprehensive analysis and demonstration according to the regional environmental capacity, so as to optimize the site selection scheme with the least impact on the environment. Chemical construction projects discharging sewage, waste gas (dust), solid waste, odor and radioactive substances shall not be constructed in the following areas: residential areas, cultural and educational areas as determined by urban planning; primary and secondary water source protection areas (including phreatic aquifers); historical sites, scenic spots, hot spring convalescent areas; nature reserves and other areas that need special protection. Chemical construction projects discharge toxic and harmful exhaust gas sheet muffler between towns and residential areas to ensure appropriate health protection distance, and set annual wind frequency on environmental protection indicators of local towns and residential areas. Toxic and harmful wastewater discharged from chemical engineering construction projects should be set up in the groundwater of surface water source, and the location of discharge outlet should be determined according to the environmental assessment report. It is forbidden to set up places for the disposal of hazardous solid waste in the protection zones with groundwater as the source of drinking water, nor within the scope of health protection designated by the local urban construction, health and environmental protection departments. The land for environmental protection facilities of muffler factory should be selected and arranged at the same time with the land for main works. In order to meet the needs of production, the most dangerous production equipment should be arranged at the farthest distance from the pollution-free equipment, and then the corresponding positions of other equipment should be determined.
