A process for integrated purification of multicomponent wastewater from heavy metals comprises the alkalization to pH of metal deposition, introduction of coagulant, settling, primary filtering, adding of sodium sulphide and secondary filtering. The water is preliminary alkalized to pH 4-5. The introduction of the coagulant is carried out before the alkalization of wastewater to pH of metal deposition. After the introduction of sodium sulphide the aluminium coagulant is added. |
