The uncertainties associated with sink mechanisms considerable complicate the problem of determining the world carbon budget and prediction of future atmosphere CO2 levels.吸收机制的不确定性相当大程度地使世界碳量平衡和预计未来大气CO2水平问题复杂化。(NOTES)
Unit 8: New Technologies of Air Pollution Control
大气污染控制的新技术
Moreover, while bioremediation techniques are now being applied successfully for the treatment of soil and groundwater contaminated by synthetic organics, at present there is very little practical experience with biological systems for the control of air contaminants among environmental professionals in the U S. 而且,生物除污技术在土壤和地下水得到了成功的应用,现在,在美国环保专业人员中,生物学系统在控制大气污染物方面只有很少的实践经验。(习题:英译汉)
In fact, few environmental professionals in this country appear to be aware that “biofiltration” i.e., the biological removal of air contaminants from off-gas streams in a solid phase reactor, is now a well established air pollution control(APC) technology in several European countries, most notably The Netherlands and Germany.实际上,这个国家几乎没有环境的专家似乎意识到在好几个欧洲国家(最显著的是荷兰和德国),“生物过滤”,即从固相反应器气流中空气污染物的生物去除法,是一种充分确立的空气污染控制技术。(NOTES)
The experiences in Europe have demonstrated that biofiltration has economic and other advantages over existing APC technologies, particularly if applied to off-gas streams that contain only low concentrations (typically less than 1000 ppm as methane) of air pollutants that are easily biodegraded.欧洲的经验已经证明,生物过滤较已有的空气污染技术有着经济的和其他方面的优越性,特别是用于仅含有低浓度{典型地是加完浓雾小于1000ppm}易生物降解的空气污染物的尾气。(NOTES)
The principal reasons why biofiltration is not presently well recognized in the U.S., and has been applied in only a few cases, appear to be a lack of regulatory programs, little governmental support for research and development, and lack of descriptions written in the English language. 对于那些为什么生物过滤法如今在美国还不是很好地被认识和只应用于仅仅很少的一些情况的道理,可以认为是缺少控制的计划、来自政府对此技术研究和发展支持,更是缺少用英语写成的有关这些技术的文献。(习题:英译汉)
While soil beds have been shown to control certain types of odors and VOC efficiently and fairly low and operating cost, their use in the U.S. has been limited by the low biodegradation capacity of soils and the correspondingly large space requirements for the beds. 虽然已经证实土壤床可用想到低的投资和操作费用来控制某些类型的臭味和挥发性有机化合物,但是,土壤的低生物降解能力和相当大的占地要求限制了土壤床在美国的应用。(NOTES)
Unit 10: Water Pollution and Pollutants
水污染及其污染源
Tests for the few pathogens that might be present are difficult and time consuming, and standard practice is to test for other more plentiful organisms that are always present (in the billions) in the intestines of warm-blooded animals,including human.对可能存在的病菌的检测不仅有难度并且很耗时,并且标准的实施是对其他许多存在于包括人类在内的热血动物肠道内德有机体进行的检测。(老是强调)
VSS can be an indicator of the organic content of raw wastes and can also provide a measure of the active microbial population in biological processes. 挥发性悬浮固体可作为原废物的有机物含量的指示指标,并为在生物过程活微生物数量提供一个测量方法。(老师强调) TOC is determined by measuring the amount of CO2 produced when the organic carbon in the sample is oxidized by a strong oxidizer and comparing it with the amount in a standard of known
TOC. 总有机碳是通过测量样品中的有机碳在一种强氧化剂的氧化作用下产生的二氧化碳的量,并与已知的总有机碳的标准对比而测得的。(老师强调)
Unit 13: Water Treatment Processes
水处理过程
Coagulation/flocculation is a chemical-physical procedure whereby particles too small for practical removal by plain sedimentation are destabilized and clustered together for faster settling. 混凝/絮凝法是一种化学物理过程,那些太小的用普通沉降法不能去除的颗粒具有在这个过程中失去稳定性能成团的特点,从而能较快地沉淀。(NOTES)
Unit 18: Sources and Types of Solid Wastes
固体废弃物的来源和种类
Although any number of source classifications can be developed, the following categories have been found useful.虽然已有许多废物来源的分类法,但以下的分类是很有价值的。(NOTES) As a basis for subsequent discussions, it will be helpful to define the various types of solid wastes that are generated.作为以下讨论的基础,定义所产生的各种固体废物是有帮助的。(NOTES) The most important characteristic of these waste is that they are highly putrescible and will decompose rapidly, especially in warm weather. 饮食废物的重要特点在于它具有易腐烂性,尤其在温暖的天气里,会极快地腐烂。(老师强调+习题:汉译英)
