LIQUID FILTERING MATERIAL, LIQUID FILTERING BOX, AND LIQUID FILTERING APPARATUS

摘要

A liquid filtering material, a liquid filtering box, and a liquid filtering apparatus. The liquid filtering box comprises a box wall pipe, a bottom plate, a box cover, a filtering material, and a water inlet pipe. The box wall pipe is in a shape of an N-prismatic pipe, a cylindrical pipe, or a cylindroid pipe, N being a natural number not less than three. At least one water discharging outlet is formed in a pipe wall of the box wall pipe. The filtering material is disposed on an inner side of the pipe wall of the box wall pipe, and therefore, to-be-filtered liquid flows from the water inlet pipe into the liquid filtering box, and filtered liquid flowing through the filtering material is discharged out of the liquid filtering box through the water discharging outlet of the box wall pipe. The liquid filtering box and the liquid filtering apparatus are more convenient and simpler to maintain, and the maintenance cost is reduced; and the efficiency of liquid filtering treatment is effectively improved by using structures of the liquid filtering box and the liquid filtering apparatus.
