某新建热电厂工程。建设2台600NW抽凝式气轮机,2台1900t/h临界燃煤锅炉,配备四电场静电除尘器及脱硫设施,1座240m高的烟囱及2座淋水面积6000m2的冷却塔。项目建设后替代三个工业区中60家印染企业的分散供热锅炉共计123台。年运转时数6600h,项目年发电量6.0×106MW·h/a,年供热量2.198×107GJ/a,平均热电比101.73%,总热效率65.5%。本项目大气污染物SO2、NOx和烟尘的排放量分别为0.63t/h,0.82t/h,0.813t/h。经预测,SO2最大地面浓度为105.7μg/m3,NO2最大地面浓度为211.4μg/m3,NO2地面浓度达标准限值10%时所对应的最远距离为37km,烟尘最大地面浓度为112.2μg/m3。拟选贮灰场位于项目所在地西北2.0km的山谷,地下水流向为西北向东南。
全年主导风向ENE。选址区位于滨海区,距市区东部约8.5km,区内工业以纺织、印染为主。煤炭以海运运输进厂。配套建设5万吨级煤炭码头。选址区南0.55km处为A村庄,东北3.0km为B镇中学,北部1.5km处为B镇区政府,工业区分布在厂址西、东南和西北。

地下水是否应该进行监测如果监测,请分析点位布置,主要监测因子的确定。

答案

参考答案:由于贮灰场区域地下水走向由东西北向南向,本次评价至少布置2个地下水监测点,在地下水走向上游事故贮灰场和地下水走向下游各布设1个监测点位,符合《一般工业固体废物贮存、处置场污染控制标准》(GB 18599—2001)中的要求。考虑到电厂灰渣中对地下水产生影响的主要污染因子,本次地下水监测主要因子可以确定为:pH、Pb、As、Cd、F、Fe、Mn、总硬度和Cr6+

A group of senior high school students are playing outside on a basketball court. They are shouting with excitement. And they all have the same dream. They wish to play in the NBA, just like Huston Rocket’s Yao Ming. “Someday, there will be more Chinese players like Yao in the NBA,” said 15-year-old Xie Tao, a senior 1 boy at Shanghai No. 2 Middle School. Xie always watches Yao playing on TV. “He is a great player. He makes me proud to be Chinese,” he said.

Like Xie, 17-year-old Liu Yan at Beijing No. 22 Middle School is also a big NBA fan. “Since early May, I’ve not missed one game in the NBA,” said the senior 3 student.

Basketball is becoming popular in middle schools across the country. And more young players are starting to like the sport. More students are playing the game.

Jiang Hui, a basketball teacher at Beijing No. 2 Middle School, said that 85 percent of the students at this school like the sport. “Students are full of passion for the game,” Jiang’s team won the regional first prize in the 2004 National High School Boy’s Basketball League in   march. The league is the first national basketball competition for high school students.

Playing basketball is a good way to exercise. But students also enjoy it for other reasons. For Li Yan, a Senior 2 at Shanghai No. 12 Middle School, basketball teaches him lessons in life. “When I am in a game, I feel more confident about my studies, “ he said. “ It also teaches me to have a good team spirit and to enjoy friendship.”
