Description
Technical Field
[0001] The utility model relates to the technical field of water treatment, in particular to a self-cleaning reclaimed water ultrafiltration device. Background Technique
[0002] Today, with the increasing importance of resource shortage and environmental protection, a self-cleaning reclaimed water ultrafiltration device is particularly important. Through advanced ultrafiltration membrane technology, this device can efficiently remove suspended solids, bacteria, viruses and some dissolved organic matters in reclaimed water, significantly improve the water quality and make it meet the reuse standard.
[0003] The working process of a self-cleaning reclaimed water ultrafiltration device mainly includes three steps: pretreatment, ultrafiltration and self-cleaning. First, the wastewater passes through the pretreatment system to remove large particle impurities and suspended solids, reducing the load on the ultrafiltration membrane. Subsequently, the pretreated water enters the ultrafiltration membrane module. Under the drive of pressure, water molecules and small molecule solutes pass through the ultrafiltration membrane, while solid particles, colloids, bacteria, etc. are intercepted. As the operation time increases, pollutants will gradually accumulate on the surface of the ultrafiltration membrane. At this time, the self-cleaning function is started, and the pollutants on the membrane surface are removed by reverse flushing or air-water mixed flushing, etc., to restore the membrane flux and water quality. The whole process realizes automatic control, ensuring the efficient and stable operation of the device.
[0004] At present, some devices on the market clean the impurities on the surface of the ultrafiltration membrane relatively superficially. In view of this, we propose a self-cleaning reclaimed water ultrafiltration device. Content of the Utility Model
