At present, from the aspect of water purification efficiency, the specific surface area of a large number of filler balls is small, so that the attachment amount of microorganisms is small, and the filler balls are easy to block by filling sponge in the filler balls, so that the direct contact area between the filler and water is further reduced; the blade type filler balls collide with each other in water, the filler ball material is aged along with the increase of the service life, the balls are damaged and fail, and from the angle of processing and manufacturing, the structure is complex, the strength is low, the manufacturing is time-consuming, easy to damage and short in service life.

In addition, because the filler balls cannot be connected in series and are operated independently, the filler balls of the fluidized bed need to be fluidized and collided under the action of aeration, so that the fluidized bed filler balls are suitable for small-scale and small-range conditions, but are not easy to realize in a pool body with larger and deeper scale, and have higher requirements on matched facilities and higher operation cost when the same effect is achieved. Neither of the above-described filler ball forms is suitable for fixed installations.
