近年来，光催化-臭氧联用技术在有机废水治理方面显示了广阔的应用前景，已成为高级氧化技术方向的研究热点。本文研究了光催化-臭氧联用技术降解有机物的特性。实验结果表明，光催化-臭氧联用技术对有机物的降解效率大大高于单一光催化和单一臭氧的降解效率，具有一定的协同效应；其产生协同效应的本质原因可能是臭氧捕获了光催化过程中产生的光致电子生成了更多的·OH自由基；有机物种类对光催化-臭氧联用技术的协同效应有一定影响，与臭氧反应速率较低的有机物协同效应较显著；有机物浓度也影响协同效应，随有机物浓度的增大，协同效应增强；同时臭氧流量对协同效应也有一定影响，臭氧流量增大，协同效应减弱。还通过实验对光催化臭氧降解有机物的作用机理进行了验证。本文还研究了光催化-臭氧联用技术对环境中典型有机污染物的降解行为，主要考察的有机物包括芳香化合物、染料、染料中间体、羧酸类化合物、醇类化合物及胺类化合物。①芳香化合物的降解 通过对苯胺降解的研究表明，pH值对光催化-臭氧联用技术降解苯胺的影响不大；无论苯胺初始浓度高低，该技术都能使苯胺废水完全降解；随通入系统中臭氧流量的增加，光催化-臭氧联用技术对苯胺的降解效果增加，降解时间缩短，但臭氧流量增大到一定程度降解效率变化已不明显。对硝基苯的降解得出与苯胺相似的结论，同时还通过GC-MS技术检测到了硝基苯降解过程中的主要中间产物，包括邻、间、对硝基苯酚、间或对二硝基苯和偶氮苯等。还研究了芳香化合物结构对光催化-臭氧联用技术降解性能的影响，结果表明，取代基性质和取代基位置对降解活性都有一定影响。②染料及染料中间体的降解 采用光催化-臭氧联用技术对中低浓度溴氨酸废水和染料中间体H酸废水进行预处理，结果表明，溴氨酸废水经过短时间催化降解，脱色率能达到70％以上，COD也能得到一定的去除，同时废水的BOD5／COD值能从％～％上升至％～％，可生化性得到大幅度提高，为后续生物处理创造了有利条件。H酸废水经4h氧化COD值能从920mg／L下降到230mg／L，BOD5／COD值从原水上升到，可生化性也得到明显改善。17种水溶性染料溶液的脱色实验表明，光催化-臭氧联用技术对染料有较强的脱色能力，而且脱色效率与染料结构之间有较密切的关系，染料共扼链长短、电子云密度、偶氮双键中的氮原子是否与邻近基团形成氢键以及取代基的电负性大小等对脱色效果都有影响。

You can help to reduce the demand for fossil fuels, which in turn reduces global warming, by using energy more wisely. Here are 10 simple actions you can take to help reduce global warming. 1. Reduce, Reuse, RecycleDo your part to reduce waste by choosing reusable products instead of disposables. Buying products with minimal packaging (including the economy size when that makes sense for you) will help to reduce waste. And whenever you can, recycle paper, plastic, newspaper, glass and aluminum cans. If there isn't a recycling program at your workplace, school, or in your community, ask about starting one. By recycling half of your household waste, you can save 2,400 pounds of carbon dioxide annually. 2. Use Less Heat and Air ConditioningAdding insulation to your walls and attic, and installing weather stripping or caulking around doors and windows can lower your heating costs more than 25 percent, by reducing the amount of energy you need to heat and cool your home. Turn down the heat while you’re sleeping at night or away during the day, and keep temperatures moderate at all times. Setting your thermostat just 2 degrees lower in winter and higher in summer could save about 2,000 pounds of carbon dioxide each year. 3. Change a Light BulbWherever practical, replace regular light bulbs with compact fluorescent light (CFL) bulbs. Replacing just one 60-watt incandescent light bulb with a CFL will save you $30 over the life of the bulb. CFLs also last 10 times longer than incandescent bulbs, use two-thirds less energy, and give off 70 percent less every . family replaced one regular light bulb with a CFL, it would eliminate 90 billion pounds of greenhouse gases, the same as taking million cars off the road. 4. Drive Less and Drive SmartLess driving means fewer emissions. Besides saving gasoline, walking and biking are great forms of exercise. Explore your community’s mass transit system, and check out options for carpooling to work or you do drive, make sure your car is running efficiently. For example, keeping your tires properly inflated can improve your gas mileage by more than 3 percent. Every gallon of gas you save not only helps your budget, it also keeps 20 pounds of carbon dioxide out of the atmosphere. 5. Buy Energy-Efficient ProductsWhen it's time to buy a new car, choose one that offers good gas mileage. Home appliances now come in a range of energy-efficient models, and compact florescent bulbs are designed to provide more natural-looking light while using far less energy than standard light products that come with excess packaging, especially molded plastic and other packaging that can't be recycled. If you reduce your household garbage by 10 percent, you can save 1,200 pounds of carbon dioxide annually. 6. Use Less Hot WaterSet your water heater at 120 degrees to save energy, and wrap it in an insulating blanket if it is more than 5 years old. Buy low-flow showerheads to save hot water and about 350 pounds of carbon dioxide yearly. Wash your clothes in warm or cold water to reduce your use of hot water and the energy required to produce it. That change alone can save at least 500 pounds of carbon dioxide annually in most households. Use the energy-saving settings on your dishwasher and let the dishes air-dry. 7. Use the "Off" SwitchSave electricity and reduce global warming by turning off lights when you leave a room, and using only as much light as you need. And remember to turn off your television, video player, stereo and computer when you're not using 's also a good idea to turn off the water when you're not using it. While brushing your teeth, shampooing the dog or washing your car, turn off the water until you actually need it for rinsing. You'll reduce your water bill and help to conserve a vital resource. 8. Plant a TreeIf you have the means to plant a tree, start digging. During photosynthesis, trees and other plants absorb carbon dioxide and give off oxygen. They are an integral part of the natural atmospheric exchange cycle here on Earth, but there are too few of them to fully counter the increases in carbon dioxide caused by automobile traffic, manufacturing and other human activities. A single tree will absorb approximately one ton of carbon dioxide during its . Get a Report Card from Your Utility CompanyMany utility companies provide free home energy audits to help consumers identify areas in their homes that may not be energy efficient. In addition, many utility companies offer rebate programs to help pay for the cost of energy-efficient upgrades. 10. Encourage Others to ConserveShare information about recycling and energy conservation with your friends, neighbors and co-workers, and take opportunities to encourage public officials to establish programs and policies that are good for the 10 steps will take you a long way toward reducing your energy use and your monthly budget. And less energy use means less dependence on the fossil fuels that create greenhouse gases and contribute to global warming.

The way in which businesses will react and behave depend on a range of factors. Micro factors may be controllable, however, companies also need to be aware of the macro factors which they cannot control but will still impact on their business. The decision of how to react then has to be taken with consideration to a range of stakeholders. Nike, as an international brand name has a large number of stakeholders, from employees, contractors and customers as well as shareholders through to less direct stakeholders such as the families of employees and residents near their offices or contracts factories. The decision they make will reflect the political, economic, social and technological environment. There are many political factors that may impact on Nike. As an international company, there is a strong association with their home nation. This American based firm sells anything sports related from trainers and football boots to T-shirts and sweatbands (Thompson, 1997). As such this company has some very profound strength. The brand name is recognised on a global basis and perceived as a good quality brand with superior performance. It has also gained a reputation as a ‘designer’ label, and as such has become very attractive to many teenagers and fashion conscious young people. With the opening up of markets and a larger amount of pull factors we can see that Nike is making success international markets such as Russian. With the current disagreement with the attitude of the US over the way in which Iraq should be dealt with there is the creation of some level of alienation. The impact may be that American goods in countries such as Russia and Germany become less popular as a result of the political environment.
