Abstract

The invention belongs to the technical field of water treatment, and particularly relates to a circulating ultrafiltration device for deep decontamination. The circulating ultrafiltration device provided by the invention mainly solves the technical problems of an existing ultrafiltration circulating device that contaminants settle on the surface of an ultrafilter membrane, and the use ratio of a water resource is not high. According to the technical scheme provided by the invention, a thick water circulation filtering system is added on the foundation of an existing ultrafiltration device, and thick water discharged from the ultrafiltration device is filtered through the thick water circulation filtering system; suspended solids and colloid impurities in the thick water filtered through the thick water circulation filtering system can be effectively removed and then the thick water enters an ultrafiltration membrane assembly to be subjected to ultrafiltration, so that the defects of contaminant sedimentation on the surface of the ultrafiltration membrane and contaminant concentration in a system are overcome, and substantive water resources are saved. The circulating ultrafiltration device provided by the invention has the advantages that the contaminant sedimentation on the ultrafiltration membrane surface is relieved, and the water utilization rate of the ultrafiltration device is improved.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to a circulating ultrafiltration device for deep decontamination. Background technique [0002] The ultrafiltration device is an advanced membrane separation technology, which uses the ultrafiltration membrane as the filter medium and uses the pressure difference on both sides of the membrane as the driving force to filter the water through the ultrafiltration membrane, and part of the water filtered through the membrane is used as the produced water Utilize, while another part of the impurities and water that have not passed through the membrane filtration is discharged as concentrated water. Because the ultrafiltration device has broad requirements on the quality of influent water, and the water produced is stable and of good quality, it is widely used in water treatment in various fields. [0003] In the application process of the existing ultrafiltration dev...
