摘　　要：采用生产工艺调研和现场监测相结合的方法,基于全过程物料衡算原理,研究了深圳市印刷企业α、塑料企业β、涂装企业γ、电子企业θ四类典型工业源涉挥发性有机物(VOCs)原辅料的使用现状、末端处理设施削减能力及无组织排放现状。研究表明:四类工业源低挥发性源头替代率低,纯溶剂物料使用比例以电子企业θ最大,占比94.1%;原辅料所产生的VOCs经收集、回收处置后,实际削减比例普遍较低,涂装企业γ相对较高,为21.5%;四类工业源VOCs无组织排放量占比均非常突出,电子企业θ无组织排放量占其排放总量的比例最高,为99.0%。为有效削减工业源VOCs无组织排放量,建议提高涉VOCs工序的废气收集率、收集废气的VOCs浓度及末端处理效率。Using the method of production process investigation and field monitoring,and basing on the principle of material balance in the whole process,the present situation of related Volatile Organic Compounds(VOCs) raw and auxiliary materials used in printing enterprises α,plastic enterprises β,coating enterprises γ and electronic enterprises θ,as well as the reduction capacity and disorganized emission of terminal treatment facilities in Shenzhen were studied.The results showed that the substitution rate of low volatile sources was low among the four industrial sources,and the proportion of pure solvent materials in electronic enterprise θ was the largest,accounting for 94.1%.VOCs generated by raw materials after collection and recycling,the actual reduction ratio was generally low,coating enterprises γ was relatively high,only 21.5%;Four types of industrial sources of VOCs unorganized emissions were very prominent,electronic enterprises θ unorganized emissions accounted for the highest proportion of its total emissions,which is 99.0%.In order to effectively reduce the unorganized emission of VOCs from industrial sources,it is recommended to improve the waste gas collection rate,VOCs concentration in the collected exhaust gas and end treatment efficiency of VOCs related processes.
