Abstract: The disposal of arsenic-containing wastewater in nonferrous smelting is accompanied by the discharge of a large number of arsenic-containing hazardous wastes, which brings great pressure to the operation and external environment of enterprises. In order to avoid environmental pollution and the secondary disposal of arsenic-containing hazardous waste, the treatment technology of wastewater with the purpose of "waste residue reduction, harmless and recycling" has attracted wide attention. The stabilization treatment of arsenic-containing hazardous waste with strong migration is also the main means to solve the existing disposal of hazardous waste. In this paper, the lime iron salt method, sulfuration method, scorodite precipitation method, concentration method and arsenic-containing wastewater treatment technology are summarized. Combined with the main characteristics of solid waste containing arsenic in the wastewater treatment, the wastewater treatment and arsenic fixation technology are analyzed in detail. Based on the current industrial application and the latest research progress of wastewater treatment technology, the prospect of new technology of arsenic-containing wastewater treatment and arsenic fixation is prospected.
