1, the project wastewater is mainly domestic sewage, the main pollutants are COD, SS, ammonia nitrogen, etc., as the project site belongs to the fourth sewage plant in Bengbu within the scope of the collection of sewage, domestic sewage after septic tank treatment of major pollutants discharged in concentration in line with the "Comprehensive Wastewater Emission Standards"
2, the project exhaust gas is mainly soldering exhaust gas, Dipping wax volatile organic waste gas. Soldering exhaust gas, wax dipping volatile organic exhaust gas collected by the air collection hood is treated by filtering device and then discharged through 15 meters high exhaust pipe (H1). Organic waste gas that is not collected is discharged without organization. Organized emissions of non-methane hydrocarbons, tin and its compounds emission concentration, emission rate to meet the "Comprehensive Emission Standards for Air Pollutants"
3, the project noise is mainly for the production of equipment noise generated by the operation of the equipment, are placed in the workshop, the noise level of 65 ~ 85dB (A), the prediction results show that, through the building sound insulation, distance attenuation, the project can meet the "Industrial" factory noise Industrial plant noise emission standards" (GB12348-2008) in the class 2 standard requirements.
