Abstract
Provided is an inorganic solid waste-microbial composite curing agent and its preparation method and application. The inorganic solid waste-microbial composite curing agent consists of the following raw materials in parts by weight: steel slag, active magnesium oxide, recycled powder, stearic acid, borax, carbonic anhydrase bacteria,, and soluble calcium salts. The preparation method includes performing granulation on steel slag, active magnesium oxide, recycled powder, stearic acid, borax, etc. into porous materials through dry rolling extrusion and compression, and loading carbonic anhydrase bacteria andinto the porous materials. By adding inorganic solid waste-microbial composite curing agent into the sludge and introducing CO, the sludge is quickly solidified through the carbonization and microbial mineralization of inorganic solid waste. At the same time, microorganisms can effectively decompose organic pollutants in the sludge, achieving the goal of harmless, stabilized and resourceful utilization of sludge.
