江苏省高等教育自学考试 （ 年） 本 科 毕 业 论 文 目废活性炭无害化及再生项目大气影响分析 专 业 主考学校 姓 名 准考证号 工作单位 指导教师 起止日期 为配合生态经济区总体规划, 强化工业固体废物综合利用和处置技术开发，将在生态经济区内拟建回收2万吨废活性炭无害化处理及再生节能环保项目。项目中立式活化炉废气中烟尘产生量为0.72t/a，产生浓度30mg/m3，NOX产生量为0.53t/a，产生浓度为22mg/m3。卧式活化炉废气中烟尘产生量为7.95t/a，产生浓度为78.5mg/m3，NOX产生量为3.54t/a，产生浓度为35mg/m3，SO2产生量为46.19t/a，产生浓度为456mg/m3。成品颗粒活性炭包装产生粉尘10t/a，产生浓度为1000mg/m3，成品粉状活性炭风选分离产生粉尘60t/a，产生浓度3000mg/m3。通过环境现状调查和对项目生产工艺过程及污染源的分析，确定其主要污染因子和排放强度。项目废气主要污染因子为SO2、NO2、PM10。。结果表明：预测废气对下风向SO2最大浓度0.0045mg/m3，NO2最大浓度为0.0060mg/m3，PM10最大浓度为0.0033mg/m3。为项目建成后的环境管理提供合理建议，避免和减轻环境问题对经济和社会发展的负面影响，从而达到促进经济、社会和环境协调发展的目的。 关键词：；；工程分析；现状调查与评价；影响预测与评价 , strengthen the comprehensive utilization of industrial solid waste and disposal technology development, will be in an ecological economic zone in the proposed recovery 2 million tons of waste activated carbon harmless treatment and regeneration energy saving and environmental protection projects. Project vertical activation furnace smoke exhaust quantity of 0.72 t/a, concentration of 30 mg/m3, NOX discharge is 0.53 t/a, concentration of 22 mg/m3. Horizontal discharge activation furnace exhaust soot of 7.95 t/a, produce the concentration of 78.5 mg/m3, NOX discharge is 3.54 t/a, concentration of 35 mg/m3, discharge of SO2 is 46.19 t/a, concentration of 456 mg/m3. Product packaging granular activated carbon powder 10 t/a, the concentration of 1000 mg/m3, finished product powdered activated carbon powder winnowing separation of 60 t/a, produce the concentration of 3000 mg/m3. Through the environment present situation investigation and analysis of the project production process and the pollution sources, to determine the main pollution factor and emission intensity. Use estimate the model to predict project on surrounding atmospheric environmental impact. The results show that the project waste gas main pollution factor for SO2, NO2 and PM10. Rating for l
