【摘要】：目前全国范围的机动车尾排污染逐年严重,首要影响的便是近年来大众关注的空气质量。呼和浩特市(以下简称呼市)为内蒙古自治区首府,所属机动车保有量逐年递增,其污染态势也越来越严重。因此,呼市所属机动车尾排污染分析及研究工作亟待开展。本课题首先通过对呼市机动车排气检测管理中心和车辆管理所进行数据调研,然后针对呼市机动车保有量进行统计分析、应用CVEM模型计算各主要污染物的排放因子,再对机动车以车型类别、燃油品种、排放国标、污染程度和车辆品牌进行了细致的划分,全面对比分析了各划分种类的4项尾排污染物(CO、HC、NOX、PM)排放情况及其对应分担率,并分析得出了以下结论:(1)线性相关:机动车保有量与GDP正线性关系良好;排污量与保有量正线性关系良好。(2)从车型类别划分方面来说:小型载客汽车的CO、HC污染排放最高;重型载货汽车的NOx、PM污染排放最高。(3)从燃油类型划分方面来说:汽油车的CO排放最高;柴油车的NOx、PM排放最高。(4)从排放标准划分方面来说:低排放标准汽车在保有量逐渐减少的情况下,其尾排污染物排放量仍占有很大比重,尤其是PM的徘放。(5)从环保标志划分方面来说:"黄标车"的4项污染物排放占比较大。(6)从车辆品牌划分方面来说:各汽车品牌中,德系车的CO排放水平最高;国产车的HC、NOX、PM排放水平最高;日系车排放水平最低。该角度作为本论文的创新点,可用作民众参考汽车品牌污染水平的泛指导参考意见。进一步针对呼市机动车尾排污染防治工作中存在的问题,从法律法规、行政措施、科研技术、实际情况、民众环保意识和辩证思维这6个方面进行分析,并提出对策建议,为呼市机动车尾排污染研究治理工作提供数据支持的同时,合理的对机动车尾排污染治理工作献计纳策。
[Abstract]:At present, nationwide vehicle exhaust pollution is serious year by year, and the primary impact is the air quality that the public has paid close attention to in recent years. Hohhot City (hereinafter referred to as Hohhot City) is the capital of Inner Mongolia Autonomous region, and the number of motor vehicles owned has been increasing year by year. The pollution situation is becoming more and more serious. Therefore, it is urgent to carry out the analysis and research work of the tail exhaust pollution of the vehicle belonging to the city. Firstly, through the investigation of the data of the vehicle exhaust detection management center and the vehicle management institute in the city, Then, according to the statistics and analysis of the vehicle ownership in Huhu City, the emission factors of the main pollutants are calculated by using CVEM model, and then the classification of the vehicle by vehicle type, fuel type, emission national standard, pollution degree and vehicle brand is carried out in detail. In this paper, the emission situation and corresponding sharing rate of four kinds of tail discharge pollutants, COHCHCONXN, are compared and analyzed, and the following conclusions are drawn: the positive linear relationship between vehicle ownership and GDP is good, and the following conclusions are obtained: (1) there is a good positive linear relationship between vehicle ownership and GDP. The positive linear relationship between sewage discharge and holding capacity is good. (2) in terms of the classification of vehicle type: the COOHC pollution emission of small passenger vehicles is the highest; The emission of no _ XO _ (PM) in heavy duty truck is the highest. (3) in terms of the classification of fuel type, the CO emission of gasoline vehicle is the highest; In terms of emission standards, low emission standard vehicles still account for a large proportion of emissions of pollutants from the tail when the number of vehicles in possession is gradually decreasing. In particular, PM Pai Fong 5) from the environmental protection label division: "Yellow car" of the four pollutants emissions are relatively large. 6) from the vehicle brand division: among the vehicle brands, German cars have the highest level of CO emissions; The emission level of HCG NOXX PM is the highest and the emission level of Japanese vehicle is the lowest. This angle is the innovation point of this paper. It can be used as a general reference for the public to refer to the pollution level of automobile brands. Further, in view of the problems existing in the prevention and control of vehicle exhaust pollution in Huhou City, from the laws and regulations, administrative measures, scientific research technology, actual situation, This paper analyzes the six aspects of people's environmental protection consciousness and dialectical thinking, and puts forward some countermeasures and suggestions, which can provide data support for the research and treatment of vehicle tail exhaust pollution in Huhu City, and at the same time, make reasonable suggestions to the control work of vehicle tail exhaust pollution.
