[0002] Fiber ball refers to the fiber made into spherical structure. These fiber balls are of different sizes, with the largest diameter exceeding 35 mm and the smallest diameter being about 15 mm. These fiber balls are placed in a filter, and the huge specific surface area and high porosity provided by the curled fibers of these fiber balls achieve the effect of filtering sewage. As a kind of deep filter, fiber ball filter is more commonly used in secondary biochemical treatment of sewage or oilfield sewage treatment. Compared with granular filter material, fiber ball filter material has larger specific surface area, greater interface adsorption and suspended solids interception, and the fiber material is soft, which can realize density adjustment or reasonable filtering mode with gradually decreasing filtering aperture along the water flow direction. This mode can realize deep filtration, and the water quality and sewage interception capacity are greatly improved. When the existing fiber filter is used for a long time, the fiber balls are dirty, and at this time, backwashing of the fiber balls is needed.
