Continuous fibrous globule filter and its filtering method

Abstract

A continuous fiber ball filtering machine and a filtering method belong to the technology filed of sewage filtration. The continuous fiber ball filtering machine comprises a continuous fiber ball filtering machine main body, a fiber ball cleaning system and a fiber ball sending-back system. A feed inlet of the fiber ball cleaning system is welded at the lower part of the continuous fiber ball filtering machine main body, the feed inlet of the fiber ball sending-back system needs to be aligned with a discharge outlet of the fiber ball cleaning system, and a discharger of the fiber ball sending-back system is arranged at the upper end surface of the continuous fiber ball filtering machine main body. The continuous fiber ball filtering machine has the advantages that the filter has the independent filtering ball cleaning system and the sending-back system, thereby realizing the continuous filtration; a step of dirty filtering ball squeezing is added, most of the sewage in the filtering ball can be squeezed in the step; a step of air flow cleaning is added, the sludge blown by the air flow is easier to concentrate in the situation that the sewage in the filtering ball is squeezed out, the air flow is used for carrying out the flush after the squeezing and the air flow cleaning, thereby reducing the water consumption for back flush; and the automatic control is easy to realize.

Description

technical field [0001] The invention belongs to the technical field of sewage filtration, and in particular provides a continuous fiber ball filter and a filtering method thereof. Background technique [0002] The fiber ball is made of fiber silk as raw material and ligated by a special process. Compared with the filter bed made of rigid granular filter materials such as traditional quartz sand, the filter bed made of fiber balls has the following characteristics: [0003] The fiber ball filter is filled with fiber balls in the container to form a bed. Since the individual fiber balls are relatively loose, the fiber filaments between the fiber balls in the bed can be interspersed with each other. At this time, the individual characteristics of the fiber balls are not important. The bed forms a whole. In an unpressurized bed, the pressure on the fiber ball is the sum of the fluid resistance of the filtered water flow, the weight of the fiber ball itself, and the gravity of ...

AI Technical Summary

Problems solved by technology

[0010] At present, the existing fiber ball sewage filtration technology has the following shortcomings: because the fiber ball is a radial sphere, the fibers near the center of the ball are dense, and it cannot be loosened during backwashing, and the retained dirt is difficult to completely remove;

[0011] When the inlet water quality is different and the outlet water quality requirements are different, it is difficult to control whether the compaction and the compaction amount are different;

[0012] It cannot be processed continuously, and backwashing must be carried out, which is a waste of time;

[0013] It is not easy to implement automatic control;
