Description

Technical Field

[0001] This utility model is a solid-liquid separation membrane cleaning device, belonging to the technical field of separation devices. Background Technology

[0002] Wastewater treatment is the process of treating wastewater using physical, chemical, and biological methods to purify it, reduce pollution, and ultimately achieve wastewater recycling and reuse, making full use of water resources. It involves separating pollutants from wastewater or converting them into harmless substances. Wastewater contains a large number of solid impurities, which need to be filtered out. Solid-liquid separation membranes can be used to separate solids and liquids in wastewater.

[0003] During the use of solid-liquid separation membranes, a cleaning device is designed to clean the membrane to prevent a large amount of impurities from accumulating and clogging it, which would reduce the filtration efficiency of the solid-liquid separation membrane. Existing cleaning devices generally use clean water and a cleaning brush to rinse the solid-liquid separation membrane back and forth to remove impurities. However, when the solid-liquid separation membrane is filtering wastewater, impurities such as grease contained in the wastewater will slowly coagulate and clog the solid-liquid separation membrane. Traditional clean water and cleaning brushes are insufficient to remove impurities such as grease. Utility Model Content
