Problems solved by technology

Both of these fiber filter materials have a disadvantage: the fiber itself is straight, or only through simple twisting, and lacks elasticity, so the porosity between the fibers is small, the bulkiness is poor, and it is easy to accumulate densely under pressure.
These factors lead to reduced sewage interception, reduced filtration rate, and difficult backwashing
At the same time, the diameter of the fiber is relatively thick, about tens to hundreds of microns, and uneven large pores are easy to form between the filter materials, which makes the filtering effect worse.

Abstract

The invention relates to a preparation method of a modified comet fiber filtering material. According to the preparation method, polyester fiber raw material is spun into yarns, the polyester fiber yarns are bundled, the polyester fiber yarn bundles are subjected to injection molding and ball pressing and then cut off to obtain the modified comet fiber filtering material. The preparation method further comprises the following steps of: 1, stirring the mechanically processed modified comet fiber filtering material in a rinsing tank, then fishing out and draining water for later use; 2, uniformly stirring a chemical solution in a container and then conveying the prepared chemical solution into an autoclave, wherein the chemical solution comprises the following components in percentage by volume: 2vol% of viscose oil, 1.5vol% of silica gel oil and the balance of water; 3, putting the modified comet fiber filtering material in the autoclave, turning on a heating power supply for increasing temperature, cutting off the power supply when the temperature rises to 110 DEG C, keeping the pressure of 0.11-0.15MPa for 2-3 minutes, then adding cooling water to the autoclave to reduce the temperature to 50 DEG C, turning on an outlet valve so that the fiber filtering material subjected to modification chemical treatment and the chemical solution flow into another container at the same time; 4, fishing out the fiber filtering material subjected to modification chemical treatment, drying in a spin dryer, taking out of the spin dryer and air-drying to obtain the finished product.

Description

technical field [0001] The invention relates to a preparation method of a novel oil removal filter material, in particular to a preparation method of a modified comet fiber filter material. Background technique [0002] In today's water treatment technology, the separation process of suspended particles in large-flow water bodies is a difficult problem that restricts water treatment engineering. To evaluate whether the filter is in a high-efficiency state, the adaptability of the filter material is the key, that is, the filter layer formed by the filter material has the characteristics of an "ideal filter layer" whose porosity gradually decreases from top to bottom during filtration. After backwashing, the filter material Fully cleaned, and the characteristics of the "ideal filter layer" are not changed. The filter uses the surface area of ​​the granular material to attach the suspended solids, and uses the gaps between the particles to store the suspended suspended solids....
