威立雅水务的污水处理技术/紧凑型工艺
活性污泥处理是污水处理中的应用最广泛的工艺，威立雅水务对该工艺进行了大副改进和创新。
这种传统工艺存在以下缺陷：
占地面积大
臭气问题与邻里关系
由于污泥膨胀可能造成的运行不稳定
为达到2002年出台的全国污水处理管理办法所制定的标准，须扩建现有水厂或升级现有的活性污泥处理厂

威立雅水务的污水处理技术/紧凑型工艺BIOSTYR ?: 生物过滤系统的终极换代产品
曝气生物滤池工艺是一项经过验证的成熟工艺，威立雅水务在该工艺的运用上具有20多年的经验。
它结合了上流式过滤与生物处理，其原理是使用聚苯乙烯滤球为介质的低密度滤料，过滤截留悬浮物体与剩余微生物。
大量微生物在滤料上生长，降解含碳与含氮污染物。
处理过的水通过滤头进入到滤池上部的公用水池内，其中一部分水用于滤池定期反冲洗（无需反冲洗泵）。

Life comes in a package. This package includes happiness and sorr ow, failure and success, hope and despair. Life is a learning proces s. Experiences in life teach us new lessons and make us a better p erson. With each passing day we learn to handle various situations. Love Love plays a pivotal role on out life. Love makes you feel wanted. Witho ut love a person could go hayward and also bec ome cruel and ferocious. In the early stage of our life, our parents are the ones who shower us with unconditional love and care, they teach us about what is right and wrong, good and bad. But we always tend to take this for granted. It is only after marriage and having kids that a person understands and beco mes sensitive to others feelings. Kids make a person responsible and m ature and help us to understand life better. Happiness and Sorrow Materialistic happiness is short-lived, but happiness achieved by bringing a smile on others face gives a certain level of fulfillment. Peace of mind is the main link to happiness. No mind is happy without peace. We rea lize the true worth of happiness when we are in sorrow. Sorrow is basic ally due to death of a loved one, failure and despair. But these things a re temporary and pass away. Failure and Success Failure is the path to success. It helps us to touch the sky, teaches us to survive and shows us a specific way. Success brings in money, fame, pride and self-respect. Here it becomes very important to keep our hea d on out shoulder. The only way to show our gratitude to God for besto wing success on us is by being humble, modest, courteous and respectf ul to the less fortunate ones. Hope and Despair Hope is what keeps life going. Parents always hope their children will do well. Hope makes us dream. Hope builds in patience. Life teaches us n ot to despair even in the darkest hour, because after every night there i s a day. Nothing remains the same we have only one choice keep movi ng on in life and be hopeful. Life teaches us not to regret over yesterday, for it has passed and is be yond our control. Tomorrow is unknown, for it could either be bright or d ull. So the only alternative is work hard today, so that we will enjoy a b etter tomorrow.
On behalf of Grant Telecommunications, I’d like to welcome you. My name is Joseph Green. Today I’d like to give you a product presentation for the new XT 3000 mobile phone. My presentation is divided into three parts. First, I’ll explain the features of the new phone. Then, I’ll talk about how the phone compares with others on the market. And lastly, I will highlight the USPs of the new product. Right, let’s start with the features first. The new XT 3000 is great and it has some excellent new features. These include voice-activated dialing. What this means is that you can say the name of the person you would like to call into the phone and it will automatically find the person’s number and dial. Another fantastic feature is the 100 mega pixel camera—you won’t miss another precious moment. When compared to other products, the XT 3000 comes out on top. I will run through some comparisons against the following three products: HR 500, Elektra v1.2 and SP 989. The HR 500 doesn’t have such an excellent 100 mega pixel camera. The Elektra v1.2, which is a similar price to the XT 3000, does not have the voice-activated dialing facility. And the SP 989, which has all the same features as the XT 3000, is much more expensive than the XT 3000. This brings me to the final part of my presentation. I would like to briefly highlight the USPs (Unique Selling Points) of the XT 3000. Firstly, it is very competitively priced. It also has the most features of any phone on the market at this price. Additionally, customers are able to buy the different parts of the phone in different colours, which enables them to customise their phone to the look they want. And finally, there are lots of accessories to further customise it. All in all, the XT is a fantastic buy! Thank you for listening. Does anyone have any questions?
1-2 XUANXUAN Hello everyone, today I want to show you a part of how the earth was made, and mainly talk about Yellowstone. As continents shift and clash, volcanoes erupt, and glaciers grow and recede, the Earth’s crust is carved in countless fascinating ways, leaving a trail of geological mysteries behind. And one of the greatest is Yellowstone National Park in Wyoming. This is one of the world’s most geologically active places, shaken by up to 5000 earthquakes every year, and with more geysers and hot springs than in the rest of the world combined. Scientists studying Yellowstone are uncovering a violent past. Carved water, crushed by ancient glaciers and blasted by the biggest volcanic eruptions ever known on the planet. And even today, Yellowstone is one of the most dangerous places on Earth.

怎样做好Presentation？成功英语演讲的万能模板 无论是职场人士还是在校学生，Presentation 都很重要。做好一个Presentation需要做好话题的准备，演讲的时候需要适宜的演讲态度以及恰当的身体语言去传递内容，不仅要讲的流畅，而且要给人真的是“讲”而不是“念”或者“背”的感觉，这需要事先把细节都考虑好，然后练习。如果没什么经验不擅长临场发挥的话，就把讲稿一字一句地都想好，包括肢体语言和互动都可以提前想想。准备充分的好处是即使紧张也不至于大脑一片空白。 Chapter I Beginners ——第一章入门篇 一、演讲开场白 1、欢迎听众(正式) - Welcome to our company - I am pleased to be able to welcome you to our company... - I'd like to thank you for coming. - May I take this opportunity of thanking you for coming 2、欢迎听众(非正式) - I'm glad you could all get here... - I'm glad to see so many people here. - It's GREat to be back here. - Hello again everybody.

流利说商务英语Level4 Unit1 Part2 Preparing a Presentation Here are some suggestions on how to prepare for a presentation： Define your goals When preparing your presentation, first define your goals. Your goals are what you want your presentation to achieve. Setting clear goals ensures your presentation is focused. For example, if you're going to give a sales presentation, your goal will be to persuade people to buy your product. List your key points Once you've defined your goals, you should think of your key points. Key points are the main ideas of your presentation. Listing them allows you to see which ones support your goals the best. For example, if you're going to promote a new product, your key points could be the product's new feature. Create your slides Once you have defined your goals and key points, you can then create your slides. In a presentation, the speaker should use slides as a visual aid. Remember not to put too much text on your slides. Good slides support what you're saying, but don't distract the audience. Anticipate questions After or even during your presentation, the audience will usually want to ask questions. So you should learn how to anticipate and answer common questions. For example, at a product launch, the audience will probably ask for details about product features. So having an in-depth understanding of the new product is crucial when preparing for the presentation. Rehearse Once you've finished your slides, you should rehearse your presentation. You can practice in front of a mirror or with a friend. When practicing, time your rehearsal and practice several times. This helps you present smoothly and confidently. Rehearsing your presentation helps you present smoothly and confidently.
