Abstract:
The electrodialyser has been used for treating the wastewater discharged from circulating cooling system.The result shows that the problems,such as electrodialysis concentration difference polarization and scaling,can effectively be solved by regularly automatic electrode reverse.When the influent conductivity is 2 596-2 600 μS/cm,the optimum operating parameters of the electrodialyser are as follows ： voltage is 90 V,electric current 6.15 A,desalination rate 71.32%,energy consumption 1.10 kW.h/m 3.The water produced by treating the wastewater discharged from circulating cooling system can meet the requirements of the quality standard of make-up water of circulating cooling system.
