Research on Wastewater Treatment Scheme Based on MVR Evaporation Process
With the rapid development of Chinese industry,the intensification of environmental pollution and the shortage of water resources are becoming increasingly severe.Conventional wastewater treatment technologies can no longer meet the treatment requirements for high salt content,high organic matter,and high toxicity wastewater.The aim of this study is to explore wastewater treatment solutions based on mechanical vapor recompression(MVR)technology.This scheme improves the efficiency of wastewater evaporation by utilizing steam generated by mechanical compression,achieving energy recovery and wastewater concentration.The system process includes wastewater pretreatment,preheating,MVR evaporator treatment,steam recompression,concentrated wastewater treatment,and steam water separation.The key design considers the selection and design of MVR evaporators to maximize evaporation efficiency.It has comprehensively considered factors such as energy recovery,wastewater pretreatment,operation optimization,and wastewater post-treatment to ensure the efficient and stable operation of the system.This wastewater treatment scheme provides a feasible technical approach for achieving zero discharge of wastewater and resource recovery.
