城市空气污染及其防治对策

Urban air pollution and the necessary preventive countermeasures

城市空气污染源分为天然源和人为源,对有毒气体、颗粒物质和温室气体等污染类型进行了分类综述,提出了一些减少污染的策略,介绍了利用污染物作用机理结合模拟分析、分子碰撞与惯性分离原理、制备复合吸附剂等原理和方法来治理空气污染的新技术。加大力度避免人为源对空气的破坏,改善和调节自然源,保持生态平衡,才能有效减少空气污染对人类的危害。

The present paper intends to introduce the urban anti-pollution strategy from the government officials to the local people themselves and summarize the latest advancements in the research in the mechanism of actions along with the study of modeling, theorem of molecular collision and inertial separation, preparation of composite adsorbents and other methods in the urban air pollution and preventive It has also brought about some suggestions on how to cut down the urban air pollution based on the references provided. To reduce the harmful pollution and avoid the destruction of the environment by people themselves and establish a healthy and harmonious social environment, it is necessary to stress the improvement of natural factors so as to keep up the balance between natural factors and human interference ones. All in all, a desirable living environment calls for every one of us to work hard for its construction. To solve the above problems, we prefer to divide the sources leading to the social and natural pollution into that coming from nature and that from human interference. As to the pollution types, it can be divided into poisonous gas, particulate matters, greenhouse-effecting waste gases and others. Last of all, the paper has also summarized all the preventive countermeasures likely to be taken by the governmental or nongovernmental constitutions in the future so as reduce the environment pollution.
