    Filtering, use filters or filter the water level in the filter layer top-down gravity to compress, filter fibers in a dense state, improve the performance of the filter layer trapped impurities, ensuring the filtered water. Flushing,  gas and water from the bottom up to the impact of disturbance, so that the filter is suspended loose bundle state, the adsorption filter layer material to be eluted interception. In order to achieve a bundle fiber filter disorderly orderly loading loading backwash filter and the best state. Use water from the upper and lower water. At this point, and in the water under the action of gravity, fiber density, fiber filter bed to promote the adjustment device is running down the fiber filter layer is compressed, the packing density gradually increased along the flow direction, the filter layer along the direction of water flow porosity gradually become smaller from the larger, the corresponding filter pore diameter and pore decreases, thus forming a particularly desirable change filter pore deep state. The filtration process both horizontal and depth filtration, as well as vertical depth filtration, thereby effectively improving the filtering accuracy. When the filter needs cleaning contaminated layer of regeneration, the washing water along the opposite direction through the fiber filter bed, the backwash water and clean air under the effect of fiber density, fiber filter bed adjusting device driven by the upward movement of the fiber filter upward, reaching loose state, air-water mixture through clean technology, and water and everything in bubble washing process, the fiber filter vertical jitter in a constant state, which makes fiber filter cleaning is very thorough, so as to achieve the desired cleaning effect
