Abstract It was difficult for a large lead and zinc smelter in Yunnan province to achieve the purpose of complete reuse and zero discharge through lime neutralization treatment. Therefore, it is necessary to innovate the deep treatment technology. Biochemistry decalcification system, membrane deep treatment system and MVR evaporation system were added to the treatment system after optimizing the process parameters of the original lime neutralization. The water quality achieved the Ⅲ category of Environmental Quality Standard for Surface Water (GB 3838-2002) by the biochemistry decalcification process. And the application of the membrane deep treatment made the water quality met the Industrial Boilers Supply Water Quality Criterion (GB 1576-2008) in China. The above processing technology achieved the complete reuse and zero discharge of wastewater. The engineering practice indicated that the deep treatment project in this study had the advantages of simple process, stable operation, good treatment effect and low cost, which provides a good reference for deep treatment and pollution control of heavy metal smelting wastewater.
