Experimental Study on Wastewater Treatment and Reuse of a Lead Zinc Mineral Processing Enterprise
A combined process of pre-treatment membrane system MVR system was designed to address the issue of excessive COD and TDS in the beneficiation wastewater of a certain enterprise.The experimental research was conducted in the enterprise.The project operation results show that the process has significant removal effects on COD and TDS in wastewater.The effluent of the pre-treatment system meets the requirements for subsequent membrane system inflow,and the cost of the pre-treatment system's chemicals is approximately 16.6 yuan/m3.The effluent of the membrane system meets the reuse water standards of the ＂Specification for Treatment and Reuse of Lead Zinc Mineral Processing Wastewater＂(YS/T 1405-2020),and the MVR system obtains crystalline salt.The stable operation of the wastewater treatment system provides technical guidance for subsequent operations.
