Some DefinitionsPart Introduction to Environmental EngineeringEngineeringEngineering is a profession (职业、专业) that applies science and mathematics to make the properties (特性) of matter and sources of energy useful in structures, machines, products, systems, and processes.Pollution can

15、nteraction of systemsPart Introduction to Environmental EngineeringMany of environmental problems will apply only within one of water, air, or land systems , justifying (证明，为作出解释) the breakdown (分解) into these categories. Such a classification is also useful for easier comprehension (理解) of related

16、problems within one system.Moreover, it is sensible because, for manager and administrative reasons, such subfields (子域) as air pollution, water supply, wastewater disposal, and solid waste disposal are often dealt with separately by governmental agencies. 133. Interaction of systemsPart Introductio

17、n to Environmental EngineeringUnfortunately, many important environmental problems are not confined (局限于) to an air, water, or land system, but involve interactions between systems. A current example is the acid rain problem stemming from (根源) the emission (排放) of sulfur dioxide (二氧化硫) and nitrogen

18、oxide gases into the atmosphere from the stacks (烟囱) of generating stations (发电厂), smelters (熔炉), and automobile exhausts (汽车尾气) 。 These gases are then transported by air currents (气流) over wide regions. Rainfall “washes them out”, creating acid rain which is harmful to aquatic life (水生生物), forests,

19、 and agricultural crops. 144. Environmental ProblemsPart Introduction to Environmental EngineeringMany major improvements to our standard of living can be attributed to the application of science and technology. With these improvements, however, have come disturbing side effects, such as lost arable

20、 land (耕地), disappearing forests, environmental pollution, and new organisms resistant to controls (微生物滋长 ). Environmental problems are always interrelated. Sometimes a solution to one problem actually creates another problem.154. Environmental ProblemsPart Introduction to Environmental EngineeringF

21、or example, when people are sick and dying from disease, it is natural to want to improve human health.When health is improved and infant mortality (婴儿死亡率) is reduced, a population explosion may result. To feed this growing pollution, natural habitats (自然栖息地) are often destroyed by turning them into

22、 farmland. As natural habitats are destroyed, the wild plants, predatory animals (食肉动物), and parasites (寄生生物) that once lived there are killed as well. 164. Environmental ProblemsPart Introduction to Environmental EngineeringBecause of the lack of predators and parasites, outbreaks of insect pests (

23、害虫) become more common. Farmers use pesticides (农药) to control the pests and protect the crops, but in the process the environment becomes polluted. The development of this entire (整个的) cycle in itself consumes fossil fuel (化石燃料) supplies that are becoming scarce. In addition, when fuels are burned,

24、 air pollutants are generated. 174. Environmental ProblemsPart Introduction to Environmental EngineeringHow does a person begin to study such a network of interlocking (相关联的) problems? To make the task (工作、任务) a bit more manageable, we should recognize what environmental problems people are up again

26、quately by the resources available in that area.Many people argue that the population explosion that has taken place in the twentieth century is now the most important problem we face. It is important first because overpopulation is a major cause of all environmental problems: Fewer people would use

27、 less oil, chop down fewer trees, and pour less sewage into rivers. 19Part Introduction to Environmental EngineeringOverpopulationSecond, overpopulation and the starvation（饥饿） that accompanies it are generally higher on our list of priorities than other environmental concerns. It is hard to argue th

28、at an area should be set aside as parkland to preserve（保护） a vanishing（消失） forest or savanna（平原，热带大草原） when that might be used to raise crops that would prevent fellow human beings from starving to death. 20专业英语翻译理论专业英语翻译理论专业英语翻译理论专业英语翻译理论21专业英语翻译理论专业英语翻译理论范文：Aerobic TreatmentAerobic means requiring

29、 the presence of free oxygen. Aerobic treatment of waste is the natural degradation and purification process in which bacteria that thrive in oxygen-rich environment break down and digest the the waste.Aerobic bacteria are like humans in that they require oxygen to survive and thrive. This is the pr

30、imary difference between aerobic systems and septic systems, you see. Septic systems depend on much less efficient anaerobic bacteria. 22专业英语翻译理论专业英语翻译理论During this oxidation process, pollutants are broken down into carbon dioxide (CO2), water (H2O), nitrates, sulphates and biomass (micro-organisms)

31、. By optimizing the oxygen supply with so-called aerators, the process can be significantly accelerated. Of all biological waste treatment method, aerobic digestion is the most widespead process used throughout the world (more than 95%).Aerobic bacteria demand oxygen to decompose dissolved pollutant

32、s. Large amounts of pollutants require large quantities of bacteria; hence the demand for oxygen will be high.The Biological Oxygen Demand (BOD) is a measure of the quantity of dissolved organic pollutants that can be removed in biological oxidation by the bacteria. It is expressed in mg/L.23专业英语翻译理

33、论专业英语翻译理论The Chemical Oxygen Demand (COD) measures the quantity of dissolved organic pollutants that can be removed in chemical oxidation, by adding strong acids. It is expressed in mg/L.The ratio BOD/COD gives an indication of the fraction of pollutants in the wastewater that is biodegradable. Aero
