The invention provides a method for removing lead-bearing industrial wastewater by utilizing silica fume dust of ferroalloy works. The method comprises the steps of preparing the silica fume dust of ferroalloy works to be porous ceramics and placing the porous ceramics in wastewater for a period of time. The method has the advantages that the method is readily available in raw material, simple inpreparation, low in cost, can be separated from a reaction system, recovered and used repeatedly, is convenient to use and high in lead removing efficiency, utilizes waste as the raw material, and has remarkable environmental protection benefit and economic benefit. And a product of the method has strong market competitiveness and high practical value.
