Application of crystallization technology in high salt industrial wastewater treatment
In order to meet the increasingly strict wastewater discharge requirement,and increase the effec-tive reuse rate of wastewater,crystallization technology has become one of preferred technology routes for high salt industrial wastewater treatment projects.The common crystallization technologies and crystallizer types were introduced,and the influence of crystallization process factors such as feed liquid concentration,residence time,stirring rate,crystallization temperature,impurities,crystal seed and crystallization equipment were analyzed.The development direction of crystallization technology for high salt industrial wastewater treatment in the future were prospected,with a view to providing guidance for the subsequent treatment and resource utilization of high salt industrial wastewater.
