文档介绍：摘要近几年来,我国大气环境质量总体上趋于好转,但局部区域仍有恶化的趋势,大气环境质量,特别是城市大气环境质量的好坏,己经引起全社会的广泛关注,改善大气环境质量已经成为我国大气污染防治工作的一项主要的内容。而要做好大气污染防治工作,首先就要对大气主要污染物的污染特征进行分析。随着城市化进程的加快,天津市区大气污染程度日趋严重,己成为人们普遍关注的待解决的问题。由于城市大气污染涉及范围广和作用因素多等特征,因而增加了污染治理难度。本论文以天津市红桥区的大气环境监测资料为依据,通过细致分析揭示了红桥区大气主要污染物的季节分布特征和年际变化特征,初步分析了造成红桥区大气污染的主要原因。影响红桥区环境空气质量的主要污染物是可吸入颗粒物、二氧化硫、二氧化氮,其中可吸入颗粒物是首要污染物。随着社会的发展和汽车保有量的持续不断增加,该区的大气污染类型正在从煤烟型大气污染向油烟型大气污染发展。最后,本论文从红桥区的产业发展、工业布局、能源结构、污染工程治理、机动车尾气控制、基础设施建设、环境执法能力、环境保护投资和宣传教育等方面提出相应的大气污染控制对策。关键词:空气污染,天津,红桥区,空气质量评价 Abstract Inrecentyears,the overallatmospheric quality of China wasimproved,but there were stillsome regional environment,especially ofurban regions,has been prehensive attention,which made improving atmospheric quality one ofthemajor tasks topreventatmospheric the very firstjob isinvestigating and analyzing sourc宅of thesepollutants and their pollution characteristics. Along eleration of urbanization process,the degree ofatmosphere pollution hasbeengradually aggravating inTianjin,it e thegeneral concerns ofPublicand theurgent theurbanatmospheric pollution characterizedby the various dements involved andinfluenced with the various factors,which hasincreased thedifficulties intheatmosphere pollutionmanagement. Based on theatmosphere detectiondata ofHongqiao Distrcit,Tianjin,this article analyses such characteristics asregional distribution,seasonal distributionandyearly changes oftheurban airpollutant,and clarifiesprimary reasons forurban airpollution. The importantpollutants ofatmospheric environment are inspirable particle, sulfur dioxide,andnitrogen dioxide,which inspirable particle istheprimary contamination ofHongqiao Districtand itismore seriousthan thepollution causedbysul缸dioxide. With thesocialdevelopment andtheincreasing car ownership,the urban airpollution ischanging fromsmoke pollution tosmoke and tailgas ofmotor vehicle pollution.
