The sewage enters the filter box 1 and slides along the filter table 3. The filter table 3 rotates under the drive of the motor 25 and rises and falls under the action of the lifting components a4 and b23, so that the mud and sand slide along the inclined surface of the filter table 3. The water flows out along the opening 31, and the accumulated sand and gravel enter the filter sand box 52 along the hole groove 11. The sand and gravel can be cleaned by pulling out the filter sand box 52. The clean water is filtered again under the action of multiple filters to obtain clean water.
