Abstract
A method for stabilizing heavy metals and antibiotics by coupling slow mineralization of a calcium phosphate liquid precursor with a continuous flow of contaminants is provided. In the method, a mixed solution containing a calcium salt, a phosphate, collagen and a polymer is pumped into a packed column with a wet packing method. To-be-treated sewage is pumped into the packed column, and heavy metals and antibiotics in the to-be-treated sewage are solidified and removed during mineralization of calcium phosphate.
