重庆市废有机溶剂产生特性

基于危险废物转移联单的归纳整理以及实地调研分析，研究了重庆市废有机溶剂的产生特性.结果表明，重庆市废有机溶剂产生行业多达11种，废有机溶剂的产生量从2011年的20万t，到2015年增加到了40多万t，，年平均增长率高达29%，2016和2017年的产生量趋于稳定状态..化工行业的产生量占总产生量的99%，其次为电子行业与汽车制造行业.重庆市的废有机溶剂主要处置方式包括精蒸馏回收，危险废物焚烧炉焚烧以及水泥窑协同处置等.结合重庆市产生行业及产生种类，回收方式等特点，对重庆市废有机溶剂的管理提出了分类回收、加大回收率及小量豁免等建议.

Characteristics of the waste organic solvents in Chongqing

As the most important industrial city in Southwest China, Chongqing produced a large amount of organic solvents. The industries were many, the production points were difference, the components of waste organic solvents were complex and changeable. Based on the summary and analysis of hazardous waste transfer sheet and field investigation, the generation characteristics of waste organic solvents in Chongqing were investigated. The results show that waste organic solvents were produced from11industries in Chongqing. The amount of waste organic solvents in 2011 were about 200,000 tons, which. increased to more than 400,000 tons by 2015. The average annual growth rate was as high as 29%. The amount tended to be stable in 2016 and 2017. The total amount was almost 99% contributed from chemical industry, followed by the electronics industry and the automobile manufacturing industry. The mainly ways to dispose waste organic solvents in Chongqing, which were distillation recovery, incineration and cement kiln co-disposal. Combined with the characteristics of Chongqing's production industry, types and recycling methods, this paper put forward some suggestions on the management of waste organic solvents in Chongqing, such as classified recycling, increasing recovery rate and small exemption.
