Research and development on industrial heavy metal wastewater treatment technology

Abstract With the development of industrial technology and the improvement of industrialization, the discharge of heavy metal wastewater gradually increases. Heavy metals are the main sources of water pollution, and heavy metal wastewater mainly comes from mines, smelting, electrolysis, electroplating, pesticide, medicine, paint, pigment and other enterprises. In this paper, the common heavy metal wastewater treatment technology is summarized, and the characteristics and treatment methods of industrial wastewater are mainly introduced.
