Performance Evaluation and Optimization Analysis of Zero Discharge Device for Desulfurization Wastewater Based on Spray Drying Technology

[摘要] The original desulphurization wastewater treatment system was reformed by spray drying technology in a thermal power plant, and the performance of the modified system was evaluated. The results show that the treatment capacity of the system is above 5m3/h. It can meet the requirements of zero discharge of desulphurization wastewater in power plant, and has many characteristics, such as simple process, reliable technology, stable operation, convenient operation and so on. At the same time, some suggestions for further optimization and improvement are put forward in view of the existing problems.
