Metal wastewater and saline wastewater are two major problems in the field of wastewater treatment. At present, common treatment methods include ion exchange, electrodialysis and reverse osmosis. The ion exchange method often uses chemical reagents to achieve regeneration, which is likely to cause secondary pollution after treatment. Electrodeionization technology can continuously operate to treat wastewater, and does not require the use of acid-base reagents to achieve resin regeneration, but the structure is complex and requires higher pretreatment. Bipolar membrane electro-regenerative ion exchange is a new technology that has been practically applied in water supply treatment by a certain enterprise. A considerable degree of ion exchange capacity, after reaching the exchange capacity, the bipolar membrane is used for water dissociation to achieve electrical regeneration of the membrane. On the basis of investigating the desalination and regeneration of groundwater (well water) by this technology, this paper studies its removal effect on simulated food processing salty wastewater, Cu2+ and Fe2+ containing simulated electroplating rinsing wastewater. Influence of operating conditions such as influent flow on the treatment effect. |
