题型:问答题

某汽车生产公司现有厂区位于市区北部,拥有2万辆小型汽车生产能力,拟投资30亿元新建年产8万辆小型汽车生产线,新厂区位于某市工业开发区内,地形简单,位于环境空气质量功能二类区,距市中心约15km。主要工程内容包括冲压车间、焊接车间、涂装车间、总装车间,以及配套的仓储物流、研发中心、办公楼等工程。在该生产项目投产后(2年建设期)淘汰现有厂区所有落后生产设备,现有厂区按照城市规划将建设为住宅区。

新建生产线主要原辅料消耗是冷轧汽车板、溶剂和涂料等,其中溶剂和涂料年用量2000 t(甲苯平均含量1.8%,二甲苯平均含量9.2%)。涂装车间工艺和现有厂区一样,为喷漆—晾干—烘干。主要废气污染源是涂装车间的烘干室、晾干室和喷漆室产生的含有机物的废气,主要污染物是甲苯和二甲苯,其中,喷漆室废气采用水旋喷漆室进行净化,废气中的漆雾分别经水幕阻挡和吸收过滤去除后,经风机从排气筒排放至室外,漆雾净化的循环水中加入了漆的凝聚剂,净化率>80%,外排二甲苯19.6t/a,甲苯量5.2t/a;烘干室排出的热废气进入燃烧装置,燃烧装置对有机物的净化率>90%,外排二甲苯7t/a,甲苯量0.6t/a;晾干室二甲苯排放量12.8t/a,甲苯3.5t/a,直接通过管道送排气筒外排。以上废气汇合后均经过1根28m高排气筒外排,废气总量30万m3/h,年运行时间300天,每天工作24小时。本项目生产工艺废水主要来自涂装车间,包括脱脂清洗废水、磷化清洗废水、电泳清洗废水和喷漆废水,主要污染物为COD、石油类、总镍、总锌和六价铬,排入厂区污水综合处理站与其他废水混合后,经生化处理进入城市污水处理厂,产生的工业固体废物有漆渣、磷化滤渣,污水处理站的污泥。目前,现有厂区COD排放总量尚不能满足当地环保局批复的总量指标,待新厂建成后,老厂区全部淘汰可满足总量要求。

[问题]

假如按照大气导则估算模式计算,二甲苯最大落地浓度出现在厂区办公楼区域,为0.105mg/m3,在距离源2000m、3000m位置(均在厂外)落地浓度分别为0.07mg/m3和0.03mg/m3,请判断该项目大气评价等级并给出判定依据,确定评价范围。(说明:《工业企业卫生标准》(TJ36—79)中居民区大气中二甲苯的最高容许浓度一次值标准为0.30mg/m3)
