Powder-shaped or slurry-shaped heavy metal waste, cement, quartz powder, fibers and additives are mixed according to certain ratios, heavy metal waste is employed as a doping material directly, and the heavy metal waste particles are solidified in tobermorite crystals with a stable structure permanently. Because an extrusion method is employed for production, the production efficiency is raised greatly, many structures with irregular shapes can be generated, utilization of heavy metal waste is accelerated, and the method has an important meaning to national treatment of heavy metal pollution. The permanent solidification method solves the heavy metal waste pollution problem, and additional products produced through the method such as tiles, pipes or plates meet the national safety standard. Through the production method, only 1-2 days are needed and the heavy metal waste permanent solidification purpose can be achieved. The production cycle is shortened greatly, the processing capability for heavy metal waste is raised, and the purposes of the permanent solidification method are achieved.
