| 摘 要： | 目前广泛使用的印刷电路板中，金属Cu的含量一般在20%~30%。废电路板熔炼企业从废电路板中回收Cu和其他金属元素，火法熔炼过程产生废气、废水和固废。选取典型火法废电路板熔炼企业，分析熔炼过程污染物排放特征，测算了主要大气污染物排放系数；对重金属的主要存在形式进行实测，揭示熔池熔炼火法工艺重金属污染物的迁移规律。确定Cu、Pb、Sn为重点控制的重金属污染物，并对不同赋存对象的占比进行比较。

| Abstract: | Content of Cu in currently widely-used printed circuit board is 20%-30%. Waste circuit board smelting enterprises recycle Cu and other metal elements from waste circuit boards, and the smelting process generates waste gas, waste water and solid waste. The pollutant emission characteristics of a typical waste circuit board smelting enterprises were analyzed and the emission coefficients of main air pollutants were calculated. The main existing forms of heavy metals were measured to reveal the migration law of heavy metal pollutants in the molten pool smelting process. Cu, Pb and Sn were determined as the key heavy metal pollutants, and the proportions of different occurrence objects were compared. |

| Keywords: | waste circuit board smelting pollutant emission heavy metals emission characteristics migration law |
