摘　　要：针对传统微电解填料昂贵、生产成本高的问题,利用冶金废弃粉尘制备微电解填料。分析了碳氧比(C/O)、还原时间、还原温度对微电解填料的化学成分、强度性质的影响,并对微电解填料的空隙率、表面形貌进行了实验研究。结果表明:在1300℃,C/O为1.0,还原时间20min的条件下制备的高含碳金属化球团满足微电解填料性能要求,为最佳制备工艺。同时,利用高含碳金属化球团对焦化废水处理进行了实验研究,COD去除率可达63%,B/C值明显提高,提高了废水的可生化性。Micro-electrolysis filler was made from metallurgical waste dust to solve the problem of high production cost. The influences on chemical composition and strength properties of micro-electrolysis filler was analyzed by different process parameters such as C/O, reduction time and reduction temperature. The void friction and surface amplification of micro-electrolysis filler were also studied. The results indicate that under the condition of reduction temperature of 1 300 ℃, C/O of 1.0 and reduction time of 15 min, the preparation technology of high carbon-bearing pellets meet the actual requirements. In the test of the treatment of coking wastewater, the COD removal rate can up to 63%, B/C increased significantly and improved the wastewater biodegradability.
