(英文)大气污染防治.docVIP

大气污染的防治 大气污染不仅对人体健康有害，更严重的是大气成分、比重的改变已引起了全球气候的变化，造成了全球性的危害。为了保护和改善大气，我们可考虑采取如下几方面措施： 首先，减少污染物排放量。多采用无污染能源，如太阳能；改革能源结构，用低污染能源，如天然气；另外，在污染物未进入大气之前，使用除尘消烟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。其次，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。因此应对不同地区、不同时段进行排放量的有效控制。再次，厂址选择、烟囱设计、城区与工业区规划等要合理，不要排放大户过渡集中，不 要造成重复迭加污染，形成局地严重污染事件发生。最后，绿化造林，使有更多植物吸收污染物，减轻大气污染程度。 我们同顶一片蓝天，我们同踏一片土地，我们只有一个地球，保护环境是我们的职责。我只希望，将来的我们能生活在一片可仰望星空的蓝天下，可以自由呼吸，只希望我们所在之地永远不会是卫星上看不到的城市。Air pollutions prevention the air pollution is not only harmful to the human body health, what is more serious was the atmospheric constituent, the proportion change has caused the global climate change, has caused the global harm. In order to protect and improve the atmosphere, we may consider that takes the following several aspect measure: first, reduces the pollutant discharge amount. Uses the non-pollution energy, like solar energy; The reform energy structure, with pollutes the energy lowly, like natural gas; Moreover, before the pollutant has not entered the atmosphere, the use dust removal smoke abatement technology and so on eliminates in the waste gas the partial pollutant, may reduce enters atmospheric pollutant quantity. Next, control emissions and full use atmosphere automatic depuration ability. The meteorological condition is different, the atmosphere is then different to the pollutant capacity, disperses into the similar quantity the pollutant, creates the pollutant density is then different. Therefore deals with the different area, the different time interval to carry on the withdrawal the active control. Once more, the factory site choice, the chimney design, the city and the industrial district plan and so on must be reasonable, do not discharge the wealthy and powerful family transition centralism, do not cause the redundant iteration pollution, forms the local serious pollution event to occur. Finally, the afforested afforestation, enables to have more plant absorption pollutant, reduces the ai
