FIELD: methods of sewage waters treatment remove ions of heavy metals; may be used in plants of hardware and nonferrous industry. SUBSTANCE: method is embodied by sorption of ions of heavy metals on organomineral sorbent based on electroplating slime granulated with polymer binder with amount of slime and binder of 75-83% and 17-25%, respectively. Polymer binder is used in the form of polymer soluble in solvents miscible with water. The method allows to treat sewage waters to the level of maximum permissible concentration of ions of heavy metals. EFFECT: simplicity and economical efficiency of the process. 3 cl, 2 tbl
