中文摘要 |
为探明浙江省制鞋行业挥发性有机物(VOCs)的治理情况、污染特征及其排放系数. 本研究以2015年浙江省490家制鞋企业调查数据为基础,分析当前浙江制鞋行业污染治理现状;并进一步筛选178家重点企业,以分析制鞋行业污染特征并核算制鞋企业及其重点工段的VOCs排放系数. 结果表明,当前浙江95%以上的制鞋企业并未能有效地处理VOCs,且大部分(约90%左右)仍使用溶剂型原辅材料;其主要污染因子为甲乙酮、甲苯、丙酮、环己酮、乙酸乙酯等10种VOCs. 另外,全省制鞋行业VOCs平均排放系数为29.5 g·双-1,其中注塑工艺为23.8 g·双-1,胶粘工艺为35.9 g·双-1;污染工段主要为刷胶复底,其排放系数为20.8 g·双-1. |
英文摘要 |
To explore the pollution characteristics and emission coefficient of volatile organic compounds (VOCs) released from the shoe-making industry in Zhejiang province, this paper used the survey data of 490 shoe enterprises obtained in 2015 to analyze the current VOCs treatment status of shoe-making industry, and further screened 178 key enterprises to study the emission coefficient of shoe-making industry. The results showed that more than 95% of shoe enterprises failed to effectively dispose VOCs, because most shoe enterprises did not have treatment facilities. Moreover, solvent-based materials such as adhesive and primer were still commonly used in approximately 90% of shoe-making industry. Meanwhile, the main pollutants of VOCs in shoe-making industry were 2-butanone, toluene, acetone, cyclohexanone, ethyl acetate, xylene, dichloromethane and cyclohexane. Furthermore, the VOCs emission coefficient of shoe-making industry in Zhejiang was 29.5 g-1, while it was affected by the production processes, and the cemented construction techniques was higher than the injection techniques, which VOCs emission coefficients were 35.9 g-1 and 23.8 g-1, respectively. Furthermore, the major polluting stage of shoe-making industry was sole attaching, in which VOCs emission coefficient could reach 20.8 g-1. |
