某集成电路公司拟建设一条生产线,进行集成电路后工序生产。从硅圆片贴膜开始,经划片、粘片、键合、封装、去飞片、镀锡、切筋、成型、测试、老化、打印、包装等一系列集成电路后工序。
废气来源:①装配室和塑封室。一部分引线框架需使用硝酸、硫酸及纯水进行清洗,因此会产生少量硝酸雾及硫酸雾。②镀锡室。镀件是集成电路引线框架脚,在镀锡及清洗过程中产生少量硝酸雾及硫酸雾废气。③标记、打印室。在使用高纯度乙醇擦拭打印痕迹时,会产生少量乙醇挥发废气。
废气产生量及治理措施:采用废气洗涤塔,将生产过程中产生的含有硝酸雾、硫酸雾的废气引至洗涤塔用碱液喷淋。治理后硫酸雾排放速率为2.0kg/h,硝酸雾排放速率为2.0kg/h。
生产工艺废水有:①镀锡废水。来自镀锡室,含硫酸、硝酸、Pb、Cu、Ni、 Fe、Sn。②划片废水。来自划片清洗工序,含有残余硝酸,呈弱酸性,有少量悬浮物。③酸碱废水。主要是纯水站离子交换树脂的再生废水,含有盐酸或氢氧化钠。④废气洗涤废水。来源于废气洗涤塔,即电镀工艺废气产生的酸性废气通过洗涤塔,用碱性溶液对其进行洗涤处理后产生的废水。主要含氢氧化钠和盐类。总排水量670m3/d,其中包括厂区生活污水。
废水治理措施:拟建一座废水处理站,对生产车间、纯水站及废气洗涤塔所排废水进行集中处理,处理后的生产废水与厂区生活污水汇合后经厂区总排口排入市政污水管线。
该项目拟建于工业开发区,污水经市政管线排入城市集中污水处理厂,由市政热力集中供热。

该项目大气环境影响评价等级为( )。

A.

一级

B.

二级

C.

三级

答案

参考答案:C

解析:根据《环境影响评价技术导则一大气环境》(HJ/T2.2-93)判断。

单项选择题

Halfway through " The Rebel Sell," the authors pause to make fun of" free-range" chicken. Paying over the odds to ensure that dinner was not, in a previous life, confined to tiny cages is all well and good. But"a free-range chicken is about as plausible as a sun-loving earthworm" : given a choice, chickens prefer to curl up in a nice dark corner of the barn. Only about 15% of "free-range" chickens actually use the space available to them.

This is just one case in which Joseph Heath, who teaches philosophy at the University of Toronto, and Andrew Potter, a journalist and researcher based in Montreal, find fault with well-meaning but, in their view, ultimately naive consumers who hope to distance themselves from consumerism by buying their shoes from Mother Jones magazine instead of Nike. Mr Heath and Mr Potter argue that" the counterculture, "in all its attempts to be subversive, has done nothing more than create new segments of the market, and thus ends up feeding the very monster of consumerism and conformity it hopes to destroy. In the process ,they cover Marx, Freud, the experiments on obedience of Stanley Milgram, the films "Pleasantville"," The Matrix" and "American Beauty", 15th-century table manners, Norman Mailer, the Unabomber, real-estate prices in central Toronto (more than once), the voluntary-simplicity movement and the world’s funniest joke.

Why range so widely The authors’ beef is with a very small group: left-wing activists who eschew smaller, potentially useful campaigns in favor of grand statements about the hopelessness of consumer culture and the dangers of "selling out". Instead of encouraging useful activities, such as pushing for new legislation, would-be leftists are left to participate in unstructured, pointless demonstrations against "globalization," or buy fair-trade coffee and free-range chicken, which only substitutes snobbery for activism. Two authors of books that railed against brands, Naomi Klein ( "No Logo") and Alissa Quart ("Branded"), come in for special derision for diagnosing the problems of consumerism but refusing to offer practical solutions.

Anticipating criticism, perhaps, Messrs Heath and Potter make sure to put forth a few of their own solutions, such as the 35-hour working week and school uniforms (to keep teenagers from competing with each other to wear ever-more-expensive clothes). Increasing consumption, they argue throughout, is not imposed upon stupid workers by overbearing companies, but arises as a result of a cultural "arms race": each person buys more to keep his standard of living high relative to his neighbors’. Imposing some restrictions, such as a shorter working week, might not stop the arms race, but it would at least curb its most offensive excesses. (This assumes one finds excess consumption offensive; even the authors do not seem entirely sure. )

But on the way to such modest suggestions, the authors want to criticise every aspect of the counterculture, from its disdain for homogenisation, franchises and brands to its political offshoots. As a result, the book wanders: chapters on uniforms and on the search for "cool" could have been cut. Moreover, the authors make the mistake of assuming that the consumers they sympathise with--the ones who buy brands and live in tract houses--know enough to separate themselves from their purchases, whereas the free-trade-coffee buyers swallow the brand messages whole, as it were.

Still, it would be a shame if the book’s ramblings kept it from getting read. When it focuses on explaining how the counterculture grew out of post-World War Ⅱ critiques of modern society, "The Rebel Sell" is a lively read, with enough humour to keep the more theoretical stretches of its argument interesting. At the very least, it puts its finger on a trend: there will be plenty of future critics of capitalism lining up for their free-range chicken.

According to Mr. Heath and Mr. Potter, consumerism can be traced back to()

A. the imposition of overbearing companies

B. the very nature of arms race

C. the ignorance of some stupid workers

D. the desire to keep up with the Jones
