High-efficiency composite emery filter

Abstract

The invention relates to water treating equipment and specifically relates to an efficient compound emery filter. The efficient compound emery filter comprises a tank, wherein a filtering water inlet pipeline, a backflushing water outlet pipeline, a filtering water outlet pipeline and a backflushing water inlet pipeline are arranged in the tank from top to bottom; a sewage disposal pipeline is jointed under a skirt base; a water divider is arranged at the top in the tank; a filtering water inlet which is connected with the water divider is arranged on the external of the tank; a filtering water outlet is arranged on the right side of the filtering water outlet pipeline; a liquid gathering pipe and a liquid collecting pipe are arranged on the filtering water outlet pipeline; a carbon protecting filter material, an efficient compound emery and a cobblestone cushion layer are filled in the tank from top to bottom. The filler in the compound emery filter can prevent the problems of a large amount of cellosilk, emery powder, fiber ball or fiber bundle plate; the filter tank has the advantages of long service life, excellent backflushing effect, low energy consumption, low daily maintenance cost and low staff operation risk; the sewage and drinking water after being filtered can meet the requirement of the secondary treatment water quality index.

Description

technical field [0001] The invention relates to water treatment equipment, in particular to a high-efficiency composite emery filter. Background technique [0002] Traditional secondary filtration technology for sewage and drinking water uses fiber ball or fiber bundle filters and ordinary corundum filters. However, the fiber ball or fiber bundle filter material in this filter will shed the fiber filaments, especially in the traditional secondary filtration technology of sewage and drinking water, it is also necessary to add a stirring electric mechanism for backwashing and decontamination on the top of the tank. The powder device makes the traditional sewage secondary filter produce a large amount of fiber filaments and emery powder, fiber balls (fiber bundles) hardening, and damage to the anti-corrosion layer of the tank during backwashing of the traditional sewage secondary filter, resulting in the secondary filtration of sewage in the sewage The two indicators of suspen...

AI Technical Summary

Problems solved by technology

It solves the problem of a large amount of fiber filaments and emery powder easily appearing in the traditional filter packing, fiber ball (fiber bundle) compaction, short service life of the anti-corrosion layer of the filter tank, poor backwashing effect, high energy consumption, high daily maintenance cost, and staff High operational risk issues
