环境评估3大气污染报告

1、年产10 万吨醋酸乙烯酯配套空分装置项目1.相关说明大气估算模式 Screen3 是一个模式，可计算点源、火炬源、面源、和体源的最大地面浓度，以及下洗和岸边熏烟等特殊条件下的最大地面浓度。经估算模式计算出的是某一污染源对环境空气质量的最大影响程度和影响范围的保守的计算结果。本次计算主要考虑醋酸乙烯过程中产生的乙醛，污染源点源，污染物为乙醛，通过估算和相关数据分析，估算乙醛挥发损失速率为 7.23g/s，按照上海市大气污染物综合排放标准标准号：DB31-933-2015，新建污染源的乙醛的一级排放标准为 20mg/𝑚3。在计算结果中，结果用不同颜色表述不同污染程度，率100%的为

2、红色，80%为黄色，10%为绿色，10%为白色。可见在 500 米以上均低于排放标准的 10%，不会造成上海市环境污染，符合绿色环保的理念。2.污染源分析2.1 污染源参数设定图 1 污染源参数给定1年产10 万吨醋酸乙烯酯配套空分装置项目2.2 污染物参数设定图 2污染物参数给定2.3参数设定图 3参数2年产10 万吨醋酸乙烯酯配套空分装置项目2.4 计算结果分析图 4计算结果2.5 计算结果图示图 5图形结果3年产10 万吨醋酸乙烯酯配套空分装置项目2.6 计算输出结果07/09/1914:44:14*SCREEN3 MRUN* VERSION DATED 96043 *SCREEN3 I
