According to the present invention, powder-like or slurry-like heavy metal waste, quick lime, gypsum powder, quartz powder or porcelain clay, fibers and an additive are matched according to a certain ratio, the heavy metal waste is directly used as the reference material and is permanently cured in the Tobermorite crystal through the stable structure Tobermorite crystal; the beater-addition process is used to produce so as to substantially improve the production efficiency, accelerate the utilization of the heavy metal waste, and provide important significance for the national treatment of heavy metal pollution; material matching, slurry preparing, black preparing molding and steam curing are performed so as to finally form the Tobermorite crystal wrapping the heavy metal waste particles; the additional products such as tiles, pipes or plates produced by using the method achieve the national safety standards; and with the production method, the permanent heavy metal waste curing purpose can be achieved only requiring 1-2 day, such that the production period is substantially shortened, and the treatment capacity on the heavy metal waste is increased so as to achieve the purpose of the present invention.
