Abstract

The invention discloses a fiber filter material and a preparation method thereof, and a filter using the fiber filter material. The fiber filter material is a particle formed by cutting at least two fiber materials after being blended, and a gap is arranged in the particle. The preparation method of the fiber filter material comprises the following steps of: 1. blending the at least two fiber materials to form a wet structure; 2. punching the net structure; and 3. carrying out hot melt cutting on the punched net structure to form the particle. The filter comprises a filter main body and the fiber filter material. The fiber filter material disclosed by the invention is high in permeability. Due to the adoption of gaps in the fiber particles and gaps among the fiber particles, the dirt holding capacity is improved, the backwashing cost is lowered, and the backwashing efficiency is improved.

Description

technical field [0001] The invention relates to a wastewater filtering technology, in particular to a fiber filter material, a preparation method of the fiber filter material and a filter using the fiber filter material. Background technique [0002] With the continuous expansion of the city scale, the amount of urban sewage generation has also increased significantly. In order to remove various floating substances and cohesive fine flocs in sewage, it is necessary to go through the processes of sieving separation, sedimentation, inertial conflict, blocking, adsorption, coagulation, etc. According to the different flow directions of sewage, the filtration methods can be divided into cross-flow gravity type and There are two types of downflow continuous gravity (pressure) type. [0003] The cross-flow gravity filtration method is to divert the sewage into the water tank or tank, and use the blanket-type fiber filter cloth to filter the sewage by gravity. Using this method t...
