【摘要】 在金属表面处理及热处理加工业,热镀锌工序会产生含锌固体废物,而各级管理部门、机构及企业对该行业含锌固体废物的分类与名称界定未有统一标准。本研究通过对热镀锌工序含锌固体废物的产生机理、相关政策、危险特性、影响因素、产废系数等方面进行分析,提出了基于热镀锌工艺不同对含锌固体废物分类管理的建议,总结了含锌固体废物减量化措施,以期能改善目前含锌固体废物管理的困境。更多还原

【Abstract】 In metal surface treatment and heat treatment industry, solid waste containing zinc is produced by the hot-dip galvanizing process, while there is no unified standard for the classification and designation of solid waste containing zinc by management departments, associations and enterprises. Based on the analysis of the generation mechanism, related policies,risk characteristics and influencing factors of the solid waste containing zinc in hot dip galvanizing process in several industries, some suggestions on the classification management and reduction measures of the solid waste containing zinc according to different hot dip galvanizing processes were put forward in order to solve the current management dilemma.更多还原
