Example of Water Treatment Upgrading and Reconstruction Project for Tailings Comprehensive Treatment Plant
A certain zinc industry limited company in Yunnan produces a large amount of mining wastewater,and the lead and cadmium content in the effluent cannot stably meet the standard.Its governance and transformation are difficult.Based on the source and characteristics of the wastewater from the plant,combined with the treatment process of the comprehensive treatment plant.In the process of production practice and technological transformation,a set of tailings wastewater treatment technology with simple treatment process and high degree of automation has been constructed.This includes using emergency pools based on rainfall,reducing the types of chemicals through experiments,and utilizing existing pool bodies to renovate them.It has achieved an increase in the amount of wastewater treatment in the water treatment workshop and a decrease in treatment costs.The actual operation results showed that the heavy metal pollutants in the wastewater are better than the requirements of the executive standard Emission Standard of Pollutants for Lead and Zinc Industry(GB 25466-2010).And this upgrading and expansion project ensured that the final effluent is stable and meets the standard.The advanced technology and successful production experience related to it can provide reference and reference for similar tailings wastewater treatment.
