在对拟建工程现场调查、类比调查和工程分析的基础上,通过原料废渣成分分析和生产工艺流程研究,对生产过程中各大气污染物的产生量进行了物料衡算,估算出排放烟气中SO_2、颗粒物、锌尘和铅尘的含量,分别为672.2mg/m~3、98.8 mg/m~3、84.8 mg/m~3和0.21mg/m~3,皆低于《工业炉窑大气污染物排放标准》GB9078-1996的二级标准。对大气污染进行预测评价,估算出SO_2的最大着地浓度,并对大气环境影响进行评价,提出相应的大气污染控制措施。
Based on the investigation, analogy investigation and project analysis of the proposed project, through the analysis of the raw material residue composition and the research of the production process, the quantity of each air pollutant in the production process was calculated and the emission of flue gas was estimated The content of SO_2, particulate matter, zinc dust and lead dust were 672.2 mg / m ~ 3, 98.8 mg / m ~ 3, 84.8 mg / m ~ 3 and 0.21 mg / m ~ Air Pollutant Emission Standards "GB9078-1996 secondary standard. Predict and evaluate the air pollution, estimate the maximum ground concentration of SO_2, and evaluate the impact of the atmospheric environment, and put forward corresponding measures for controlling air pollution.
