Description
Technical Field
[0001] The utility model relates to the technical field of caustic soda water filtration, and specifically, to a filtration device for ion-exchange membrane caustic soda water resource recovery. Background Art
[0002] Ion-exchange membrane caustic soda water resource recovery is a water resource recovery method using ion-exchange membrane technology, mainly used for treating wastewater containing alkaline substances, such as caustic soda wastewater. This method can effectively recover water resources and reduce the environmental pollution of wastewater. The process of ion-exchange membrane caustic soda water resource recovery usually includes pretreatment, ion exchange, separation, regeneration, water quality adjustment, etc. Through the ion-exchange membrane caustic soda water resource recovery technology, effective treatment and resource recovery of alkaline wastewater such as caustic soda wastewater can be achieved, which helps to reduce water resource consumption, reduce the impact on the environment, and improve resource utilization efficiency.
[0003] During pretreatment, users usually filter the suspended solids and impurities in caustic soda wastewater through a filtration device to facilitate subsequent treatment of caustic soda wastewater. Most of the existing caustic soda wastewater filtration devices remove the suspended solids in caustic soda wastewater by manually adding flocculants. This method increases the filtration steps, thus increasing the working intensity of the staff. Moreover, the existing caustic soda wastewater filtration devices can only remove the suspended solids in caustic soda wastewater and cannot remove the alkaline substances in caustic soda wastewater. This leads to the need for users to remove the alkaline substances in the waste alkali water through an additional device after filtration, resulting in a reduction in the treatment efficiency of the alkali water. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a filtration device for ion-exchange membrane caustic soda water resource recovery, to solve the problem that during pretreatment, users usually filter the suspended solids and impurities in caustic soda wastewater through a filtration device to facilitate subsequent treatment of caustic soda wastewater. Most of the existing caustic soda wastewater filtration devices remove the suspended solids in caustic soda wastewater by manually adding flocculants. This method increases the filtration steps, thus increasing the working intensity of the staff. Moreover, the existing caustic soda wastewater filtration devices can only remove the suspended solids in caustic soda wastewater and cannot remove the alkaline substances in caustic soda wastewater. This leads to the need for users to remove the alkaline substances in the waste alkali water through an additional device after filtration, resulting in a reduction in the treatment efficiency of the alkali water.
