餐饮源挥发性有机物排放计算修正方法探讨--以上海为例

Discussion On Correction Method of Volatile Organic Compound From Cooking Emissions--Case Study For Shanghai

针对不同的就餐形式将餐饮源分为家庭餐饮、食堂餐饮和社会餐饮三种餐饮类型。为完善和细化家庭餐饮、食堂餐饮和社会餐饮挥发性有机物核算方法,通过统计年鉴、行业报告、餐饮情报小程序、外卖热力图小程序、美团网页及美团APP等多渠道获取数据,从而获得就餐人次对三种餐饮类型进行计算。细化了社会餐饮VOCs排放,分菜系对外卖及到店餐饮进行核算;明确了家庭餐饮VOCs排放并修正了其产污系数。以上海市为例分别使用技术手册、二污普及新方法计算了上海2019年餐饮源VOCs排放量,验证了新方法计算结果的合理性。并从菜系、区县、排放强度三方面对新方法的结果进行分析,表明上海市餐饮源VOCs除小吃餐饮和其他菜系外的主要排放贡献菜系是烧烤、江浙菜和粤菜,各区县中浦东新区是主要排放贡献区县,虹口区的单位面积排放强度最大,为上海餐饮业管控提供依据。

According to different dining forms,the catering sources are divided into three types:family catering,canteen catering and social catering.In order to improve and refine the accounting methods of volatile organic compounds in family catering,canteen catering and social catering.In order to improve and refine the accounting methods of volatile organic compoundsin family catering,canteen catering and social catering,the data were obtained through multiple channels such as statistical yearbook,industry report,catering information applet,takeout heat map applet,meituan website and meituan app,so as to obtain the number of diners,and calculate the three catering types.The VOCs emissions from social catering was refined,and the takeout and in store catering were accounted by cuisine.The VOCs emission from family catering was clarified and the pollution coefficient was corrected.Taking Shanghai as an example,the VOCs emissions of catering sources in Shanghai in 2019were calculated by using the technical manual and the new method of secondary pollution popularization,which verified the rationality of the calculation results of the new method.The results of the new method were analyzed from three aspects:cuisine,districts and counties,and emission intensity.It shows that the main emission contributing dishes of catering source VOCs in Shanghai are barbecue,Jiangsu and Zhejiang cuisine and Guangdong cuisine,Pudong New Area is the main emission contributing district and county,and Hongkou District has the largest emission intensity per unit area,which provides a basis for the management and control of Shanghai catering industry.
