METHOD FOR CLEANING ACID SLUDGY ON DISC FILTER

摘要

PURPOSE: A method for washing disk filters is provided to efficiently implement a washing process by implementing a soaking process, an ultrasound wave-vibrating process, a rinsing process, and a drying process. CONSTITUTION: A method for washing disk filters includes the following: while disk filters are soaked with heated washing liquid for 15 to 30 minutes, the temperature of the washing liquid is kept at a temperature of 80 to 100 degrees Celsius; acid sludge is removed from the disk filters in the washing liquid based on ultrasound wave-vibration; the disk filters without the acid sludge is rinsed in a rinsing bath(40); the disk filters through the rinsing bath are dried by using an air spraying operation.
