摘　　要：将漆渣经高温热解处理脱除有害有机物组分,并替代商业金属锌粉用于置换脱除车间浸出液中的铅、镉杂质,净化后的溶液进一步生产电积锌。结果表明,采用11倍理论含量的热解漆渣在70℃下分为三段置换去除铅镉杂质,对应浓度由796 mg/L和48 mg/L分别降低至1.2 mg/L和0.8 mg/L,净化后溶液电积的指标和车间生产电积锌相当。研究为含锌漆渣的资源化利用提供了新方向。The paint residue is subjected to high-temperature pyrolysis treatment to remove harmful organic components,and the pyrolyt-ic residue was used to replace metal zinc to remove Pb and Cd impurities.The purified leaching solution obtained was further used to produce elec-trode-deposited zinc.The results showed that the concentration of lead and cadmium were reduced from 796 mg/L and 48 mg/L to 1.2 mg/L and 0.8 mg/L,respectively,by three-stage replacement reaction at 70℃with 11 times the theoretical content of pyrolytic paint residue,remove lead and cad-mium impurities.In the electrode deposition operation after purification,the index is closed to that of workshop production of electrode-deposited zinc.The research provides a new direction for the resource utilization of zinc-containing paint slag.
