第七题    油田验收

    某油田开发工程环境影响报告书于2006年3月获得批复。目前，该工程已试运行3个月，现对其进行竣工环境保护验收调查。

    该工程处于半干旱地区，区域以农业生态系统为主，零星分布有湿地，有少量天然草本植物，无受保护的野生动植物，该地区主导风向为西北风。工程开发面积32km²，设计产能2.0×10⁵t/a。敷设地下集油管线长度140km，建设联合站3座，全年生产。环境保护行政主管部门批准联合站废水COD的排放总量为11t/a。

    联合站污水处理装置稳定运行，月均排放废水1.5×10⁴m³。出水COD实测浓度70mg/L，出水排入一天然湿地。湿地与一河流连通，河流为Ⅲ类水体。COD排放浓度限值为100mg/L。经测算，天然湿地水力停留时间约36d，COD的去除率为20%。

    联合站设2×2.8MW燃油锅炉，1用1备。锅炉房烟囱高35m，实测SO₂排放量为420mg/Nm³。联合站东边有一村庄。两者相距90m。村庄最高建筑物高15m，距离锅炉房烟囱最近距离130m。

        [注：《锅炉大气污染物排放标准》(GB 13271—3001)规定，燃油锅炉浓度限值为900m/Nm³，装机总容量为2.8～＜7MW的锅炉房烟囱最低允许高度35m。]

        [问题]

竣工环境保护验收调查时应如何执行《声环境质量标准》和《城市区域环境噪声标准》

[听力原文]8-10

W: Mother’s Day is coming, what will you send to your mom

M: I’ve no idea. What about you

W: My mom is on a business travel; I guess she can’t be back on that day.
