China’s electroplating sludge production is large, and a large number of toxic heavy metals are enriched, which is a hazardous waste. This paper introduced the principle, advantages and disadvantages of the traditional treatment process of electroplating sludge. Based on the existing problems of the current process, and according to the characteristics of various copper-containing secondary resource materials, different treatment processes were used to merge the smelting process, and an integrated innovation process of “oxygen-enriched side-blown submerged combustion smelting-oxygen bottom-blown continuous blowing” was proposed. At the same time, taking a copper-containing secondary resource utilization project as an example, the application effect of the process in the comprehensive utilization of copper-containing electroplating sludge and copper-containing solid waste was expounded. The process has the advantages of both side-blown submerged combustion and bottom-blown smelting, and has the advantages of wide adaptability of raw materials, high thermal efficiency, low investment and low operating cost. It has effectively realized the ' reduction, recycling and harmlessness ' of industrial solid waste, and created a new benchmark for the solid waste disposal industry.
