【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。更多还原

【Abstract】 The paint residue is subjected to high-temperature pyrolysis treatment to remove harmful organic components,and the pyrolytic residue was used to replace metal zinc to remove Pb and Cd impurities.The purified leaching solution obtained was further used to produce electrode-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 cadmium 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.更多还原
