黃河治理英語作文? 空氣污染英語作文120字?
一、黃河治理英語作文?
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、空氣污染英語作文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、室外空氣污染如何治理?
空氣污染的解決方法有:
1、減少污染物排放量。改革能源結構,多采用無污染能源(如太陽能、風能、水力發電)和低污染能源(如天然氣),對燃料進行預處理(如燒煤前先進行脫硫),改進燃燒技術等均可減少排污量。另外,在污染物未進入大氣之前,使用除塵消煙技術、冷凝技術、液體吸收技術、回收處理技術等消除廢氣中的部分污染物,可減少進入大氣的污染物數量。
2、控制排放和充分利用大氣自凈能力。氣象條件不同,大氣對污染物的容量便不同,排入同樣數量的污染物,造成的污染物濃度便不同。對于風力大、通風好、湍流盛、對流強的地區和時段,大氣擴散稀釋能力強,可接受較多廠礦企業活動。逆溫的地區和時段,大氣擴散稀釋能力弱,便不能接受較多的污染物,否則會造成嚴重大氣污染。因此應對不同地區、不同時段進行排放量的有效控制。
3、合理規劃工業區與非工業區。廠址選擇、煙囪設計、城區與工業區規劃等要合理,不要排放大氣過度集中,不要造成重復迭加污染,形成局部地區嚴重污染事件發生。
4、綠化造林。茂密的林叢能降低風速,使空氣中攜帶的大粒灰塵下降。樹葉表面粗糙不平,有的有絨毛,有的能分泌粘液和油脂,因此能吸附大量飄塵。蒙塵的葉子經雨水沖洗后,能繼續吸附飄塵。如此往復攔阻和吸附塵埃,能使空氣得到凈化。不要亂扔廢棄物,完美的城市是人人的責任。
五、治理空氣污染可以采取哪些措施?
控制污染源是防治大氣污染危害的根本措施,而治理途徑是多方面的。
1、工業合理布局,以方便于污染物的擴散和工廠之間互相利用廢氣,減少廢氣排放量。
2、實行區域集中供熱,以高效率的鍋爐代替分散的低矮煙囪群,以高效率的鍋爐代替分散的低矮煙囪排放方式。這是城市大氣污染防治的有力措施。
3、改變燃料構成。如城市工業和民用煤氣、液化石油氣的發展,低硫燃料和新能源(太陽能、風能、地熱等)的采用。要推行采煤,以除去煤中大部分硫(主要是硫鐵礦硫)。
4、減少汽車廢氣排放。主要是改時發動機的燃燒設計和提高油的燃燒質量,加強交通管理。
5、工業裝置排放的有毒氣體,要從工藝改革和回收利用方面予以控制。
6、煙囪除塵。煙氣中二氧化硫控制技術分干法(以固體粉未或顆粒為吸收劑)和濕法(以液體為吸收劑)兩大類。
六、空氣污染治理十大措施?
空氣污染治理的十大措施包括限制工業排放,加強交通管理,推廣清潔能源,加強城市綠化,建立空氣質量監測體系,鼓勵綠色出行,加強大氣污染源治理,加強環保法規法規執行,提高公眾環保意識和文化素質,開展空氣污染治理技術研究。這些措施都是通過限制污染源,提高治理技術技術和加強環保法規等多種手段,綜合治理空氣污染,保護環境和民眾的健康。在治理空氣污染的過程中,需要政府和市民的共同努力。政府應加強立法、宣傳和監管,市民應加強環保意識和落實環保行動,如廢物分類、綠色出行等。同時,科研人員也應積極探索空氣污染治理的先進技術,為實現無污染環境作出貢獻。
七、環境問題及其治理方法英語作文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、鐘南山是如何看待空氣污染治理的呢?
前兩天,沙塵、霧霾天氣席卷我國北方大部地區,大有“黃沙蔽日”“黑云壓城”之勢,讓民眾產生了不小的心理壓力。
而另一種空氣污染對人體健康的影響,因其在視覺上的不可見而被人忽視了。“通常大家對于空氣的評判都比較主觀,眼見為實,但其實一些看不見的,譬如臭氧,更需要關注。”在3月28日召開的2018年全國社會發展創新工作會上,中國工程院院士、國家呼吸系統疾病臨床醫學研究中心主任鐘南山接受媒體采訪時說。他表示,臭氧雖然不會造成霧霾,但其濃度過高,對心臟以及很多神經系統都會產生影響。譬如在珠三角地區,霧霾已經相對較少,基本能達標,但空氣污染治理還在進行,關鍵就是臭氧問題還沒有解決。鐘南山提醒大眾,空氣污染對人體健康的危害,絕不能僅僅考慮室外空氣。“室內空氣是大氣污染的重要部分,通常我們80%的時間都在室內活動,室內除了大氣污染以外,二手煙、各種家具、不合格的裝修等,都會產生很多的疾病。最突出的是兩種,一是過敏性疾病,二是血液病。”九、如何治理打架作文?
