摘要：随着中国经济的快速增长,不断增长的能源消耗和机动车辆加重了中国城市大气环境的负担,城市空气污染作为一个主要的环境问题正迅速地凸现出来。本文选取常州市作为研究对象,通过资料收集整理和实地调查,对常州市的环境空气质量现状和大气污染特征进行了深入分析;对常州市的环境现状进行了评价。常州市的大气污染比较情况严重，颗粒物是常州市大气污染的首要污染物。化石燃料的燃烧、汽车尾气的排放和道路扬尘是近年来颗粒物污染的主要污染源。大气中的污染物会对人类产生不良的影响,治理大气污染已成为节能减排的主要措施之一。本文对常州市现阶段大气中主要污染物的基本治理方法和防治措施进行了论述,包括减少大气污染物产生的措施、大气污染治理技术、加强监管与执法等内容。对于大气颗粒物污染治理工业治理方法有很多，如文中所列。但每种方法都有其使用条件和使用环境，对于不同地域和不同条件还应根据各自需求选择正确的方式方法。

Abstract：With China's rapid economic growth, growing energy consumption and motor vehicles has increased the burden on the urban atmospheric environment in China,Urban air pollution was emerged as a major environmental problem.In the paper,the atmospheric capacity of Changzhou city was selected as the research topic of this thesis.The current situation of air quality and characteristics of air pollution of the city were evaluated by data collection and field survey.Through evaluating the actuality of the city,the main polluting gene--was confirmed.air pollution in Suzhou is more serious. particulate is the major air pollutant in Changzhou city. fossil fuel combustion, the emissions of automotive exhaust and road dust are the main pollution sources of recent years’ Particulate air pollution.The atmosphere would have an adverse effect on human beings,and to control air pollution has become a major energy-saving emission reduction measures.In this paper,aimed at the present stage of the major pollutants in the atmosphere,the basic treatment methods and preventive measures were discussed,including prevention measures of production of atmospheric pollution,control technology of atmospheric pollution,enhancing the supervision and law enforcement,etc.As for the pollutions on atmospheric particulates,indicate on the paper，there are many ways in treating the industry.However, every method has its own conditions and ranges of use. For different areas and conditions,we should choose correct ways according to the different individual needs.
