Problems solved by technology

[0008] (2) With the increasing scale of water treatment, the water pumps and fans used for backwashing and the amount of water consumed are also increasing, resulting in high energy consumption and a large footprint
However, the bottom of this module has no slope, and it is difficult to discharge mud

Embodiment 1

[0044] Embodiment 1: as figure 1 As shown, the raw water enters the casing 2 from the water inlet 12, and due to the obstruction of the outlet weir 3, the water level gradually rises until it submerges the sheet filter assembly 10, and then enters the filtration stage after the water overflows. Raw water is filtered from the outside to the inside by the blanket-like braids on both sides of the filter material assembly 3 to be purified. The clean water is converged to the outside of the partition plate 4 through the water collecting main pipe 11, then overflows from the water outlet weir 3, and is discharged to the clean water outlet 1. With the extension of the filtration time, the interception capacity of the filter material increases, and the filter resistance increases, which makes the water level in the shell rise. When it reaches a certain set height, it means that the filter material needs to be cleaned. At this time, the dredging pump 17 starts, and the trolley 7 begi...

Abstract

The invention belongs to the technical field of water treatment, and specifically relates to a vertical sheet filter. The vertical sheet filter comprises a water outlet, a housing, an effluent weir, a side splitter, a guide rail, an emptying port, a dolly, a backwashing component, a filtering component, a water header, a water inlet and a sludge chamber. The water inlet, the water outlet and the emptying port are respectively arranged under the housing; the sheet filtering component is vertically arranged in the housing; the dolly is arranged on a dolly guide rail on top of the housing and can move on the guide rail; a dredge pump is fixed under the dolly; one end of a dredge tube is on two sides of the sheet filtering component, and the other end is connected to the dredge pump through a dredge header tube; and a spoil disposal plate with a certain gradient is arranged at the housing bottom. Because of usage of a light filter material and valve-free operation, the invention has characteristics of large filtering area, low filtering load, small backwashing water consumption, flexible system configuration, low energy consumption, small land occupation, simple operation and maintenance and high degree of automation, and can be combined with routine water treatment technology to realize a higher purifying efficiency.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to a vertical sheet filter. Background technique [0002] Since the emergence of natural slow filters, the form of filters and the materials of filter materials are constantly changing. The forms of filters include ordinary fast filters, double-valve filters, siphon filters, valveless filters, and soda recoil filters. etc.; filter materials include quartz sand, white coal, ceramsite, discs, plastic beads, microporous tubes, fibers, etc. The changes are mainly carried out around three aspects: [0003] (1) Reduce the use of valves to save investment and reduce operating links. [0004] (2) Change the variety and combination of filter materials. In order to improve the sewage interception ability of the filter material and improve the water quality of the effluent, and it is easy to implement backwashing. [0005] (3) Save backwash water, reduce water pressure,...
