| 中文摘要 |
| 以2015年310家木制品企业调查数据为基础，分析当前浙江木制品行业VOCs污染治理情况，并筛选出213家重点企业，分析木制品行业污染特征并计算VOCs排放系数. 结果表明，浙江94%以上的木制品企业未能有效处理VOCs，且大部分企业仍使用溶剂型原辅材料，主要污染因子为二甲苯、乙酸丁酯、乙酸乙酯、甲苯、甲醛等9种VOCs. 全省木制品行业VOCs排放系数为9.34 kg·（万元）-1，其中胶粘工艺排放系数为0.95 kg·（万元）-1，涂装工艺为9.36 kg·（万元）-1；涂装为主要污染工段，其中水性（UV）涂料使用企业排放系数为3.10 kg·（万元）-1，溶剂型涂料企业中，木质家具生产企业排放系数高达16.85 kg·（万元）-1. |
| 英文摘要 |
| To explore the pollution characteristics and emission coefficient of volatile organic compound (VOCs) released from the woodwork-making industry in Zhejiang province, this paper used the survey data of 310 woodwork enterprises obtained in 2015 to analyze the current VOCs treatment status of woodwork-making industry, and further screened 213 key enterprises to study the emission coefficient of woodwork-making industry. The results showed that more than 94% of woodwork enterprises failed to effectively dispose VOCs since most woodwork enterprises did not have treatment facilities. Moreover, solvent-based materials such as adhesive and paint were still commonly used in woodwork-making industry. Meanwhile, the main pollutants of VOCs in woodwork-making industry were dimethyl benzene, butyl acetate, ethyl acetate, toluene and formaldehyde. Furthermore, the VOCs emission coefficient of woodwork-making industry in Zhejiang was 93.4 g·(million Yuan)-1, while it was affected by the production processes, and the VOCs emission coefficient of enterprises using the coating techniques was higher than that using the adhesive techniques, being 93.6 g·(million Yuan)-1 and 9.5 g·(million Yuan)-1, respectively. Furthermore, the major polluting stage of woodwork-making industry was coating stage, and the VOCs emission coefficient was 31.0 g·(million Yuan)-1 when waterborne and UV coating was used. The highest VOCs emission coefficient was from wooden furniture manufacturers, which could reach 168.5 g·(million Yuan)-1 when solvent-based coatings were used. |
