一、黄河治理英语作文?

Majestic tall buildings, endless vehicles, bustling crowds. The level of urbanization and industrialization has increased. But infrastructure is seriously lagging behind. The treatment capacity of sewage, smoke and waste is far lower than their production. There are only a few sewage treatment plants in Lanzhou, Xi'an and Taiyuan in the middle and upper reaches of the Yellow River, but the quantity and depth of treatment are far from enough compared with the discharge.

二、空气污染英语作文120字?

Air pollution is one of the major problems of the modern world. A great deal of energy is needed to run the factories of modern industrial nations. Automobile, trains, planes and busses need energy, too. Nearly all of this energy is produced by burning fuels. The burning produces wastes, some of which remain in the air, causing air pollution.

Scientists are finding ways to stop air pollution especially in big industrial areas and densely-populated cities. They are studying new ways of generating electricity that may be less damaging to the environment. In the meantime, many power plants are being modernized to give off less polluted material. Also, engineers try to design and locate new power plants to do minimum damage to the environment.

However, it may be that we still have a long way to go before we have a "clean" world. Nearly all of the countries are trying hard to prevent and control air pollution. There indeed seems to be no end to tasks that environmentalists will be required to do. People will continually find new ways to control pollution

四、室外空气污染如何治理?

空气污染的解决方法有:

1、减少污染物排放量。改革能源结构,多采用无污染能源(如太阳能、风能、水力发电)和低污染能源(如天然气),对燃料进行预处理(如烧煤前先进行脱硫),改进燃烧技术等均可减少排污量。另外,在污染物未进入大气之前,使用除尘消烟技术、冷凝技术、液体吸收技术、回收处理技术等消除废气中的部分污染物,可减少进入大气的污染物数量。

  2、控制排放和充分利用大气自净能力。气象条件不同,大气对污染物的容量便不同,排入同样数量的污染物,造成的污染物浓度便不同。对于风力大、通风好、湍流盛、对流强的地区和时段,大气扩散稀释能力强,可接受较多厂矿企业活动。逆温的地区和时段,大气扩散稀释能力弱,便不能接受较多的污染物,否则会造成严重大气污染。因此应对不同地区、不同时段进行排放量的有效控制。

  3、合理规划工业区与非工业区。厂址选择、烟囱设计、城区与工业区规划等要合理,不要排放大气过度集中,不要造成重复迭加污染,形成局部地区严重污染事件发生。

  4、绿化造林。茂密的林丛能降低风速,使空气中携带的大粒灰尘下降。树叶表面粗糙不平,有的有绒毛,有的能分泌粘液和油脂,因此能吸附大量飘尘。蒙尘的叶子经雨水冲洗后,能继续吸附飘尘。如此往复拦阻和吸附尘埃,能使空气得到净化。不要乱扔废弃物,完美的城市是人人的责任。

五、治理空气污染可以采取哪些措施?

控制污染源是防治大气污染危害的根本措施,而治理途径是多方面的。

1、工业合理布局,以方便于污染物的扩散和工厂之间互相利用废气,减少废气排放量。

2、实行区域集中供热,以高效率的锅炉代替分散的低矮烟囱群,以高效率的锅炉代替分散的低矮烟囱排放方式。这是城市大气污染防治的有力措施。

3、改变燃料构成。如城市工业和民用煤气、液化石油气的发展,低硫燃料和新能源(太阳能、风能、地热等)的采用。要推行采煤,以除去煤中大部分硫(主要是硫铁矿硫)。

4、减少汽车废气排放。主要是改时发动机的燃烧设计和提高油的燃烧质量,加强交通管理。

5、工业装置排放的有毒气体,要从工艺改革和回收利用方面予以控制。

6、烟囱除尘。烟气中二氧化硫控制技术分干法(以固体粉未或颗粒为吸收剂)和湿法(以液体为吸收剂)两大类。

六、空气污染治理十大措施?

空气污染治理的十大措施包括限制工业排放,加强交通管理,推广清洁能源,加强城市绿化,建立空气质量监测体系,鼓励绿色出行,加强大气污染源治理,加强环保法规法规执行,提高公众环保意识和文化素质,开展空气污染治理技术研究。这些措施都是通过限制污染源,提高治理技术技术和加强环保法规等多种手段,综合治理空气污染,保护环境和民众的健康。在治理空气污染的过程中,需要政府和市民的共同努力。政府应加强立法、宣传和监管,市民应加强环保意识和落实环保行动,如废物分类、绿色出行等。同时,科研人员也应积极探索空气污染治理的先进技术,为实现无污染环境作出贡献。

七、环境问题及其治理方法英语作文120字?

With the improvement of our living standard, more and more people can afford a car. As a result, our roads are more often than not crammed with cars. However, with more and more waste gas being discharged by the cars, the problem of air pollution becomes even more serious. So nowadays we advocate to lead a low-carbon life.

My suggestion is we should ride bikes more often instead of driving cars.By riding a bike, we can not only exercise our body but also protect our environment.

八、钟南山是如何看待空气污染治理的呢?

前两天,沙尘、雾霾天气席卷我国北方大部地区,大有“黄沙蔽日”“黑云压城”之势,让民众产生了不小的心理压力。

而另一种空气污染对人体健康的影响,因其在视觉上的不可见而被人忽视了。“通常大家对于空气的评判都比较主观,眼见为实,但其实一些看不见的,譬如臭氧,更需要关注。”在3月28日召开的2018年全国社会发展创新工作会上,中国工程院院士、国家呼吸系统疾病临床医学研究中心主任钟南山接受媒体采访时说。他表示,臭氧虽然不会造成雾霾,但其浓度过高,对心脏以及很多神经系统都会产生影响。譬如在珠三角地区,雾霾已经相对较少,基本能达标,但空气污染治理还在进行,关键就是臭氧问题还没有解决。钟南山提醒大众,空气污染对人体健康的危害,绝不能仅仅考虑室外空气。“室内空气是大气污染的重要部分,通常我们80%的时间都在室内活动,室内除了大气污染以外,二手烟、各种家具、不合格的装修等,都会产生很多的疾病。最突出的是两种,一是过敏性疾病,二是血液病。”
