Problems solved by technology

However, during the filtration and rotation process of the turntable filter, the filter cake formed on the turntable is easily destroyed, which affects the water outlet effect, and due to the limitation of the design principle of the turntable filter, the actual effective filtration area only accounts for 10% of the total turntable area during the filtration process. One-half; moreover, this kind of turntable filter needs to drive the whole turntable to rotate, which has high energy consumption and troublesome maintenance

Embodiment Construction

[0035] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0036] Such as Figure 1 to Figure 6 As shown, the filter pool includes:

[0037] A square pool body 1 with an open top, the pool body 1 has a water inlet 11 on one side wall along the longitudinal direction, and a water outlet 12 on the other side wall opposite to it;

[0038] A multi-piece unit filter element 2 arranged in parallel to each other vertically erected in the pool body 1, each unit filter element 2 includes a filter element frame 21 and filter cloths 22 laid on both sides of the filter element frame 21;

[0039] And, in the said pond body 1, there is erected a bottom connected to the inner wall of the pond body 1 at the end of the water inlet 11, and a baffle plate 13 whose top is higher than the top of the filter cartridge frame 21, so that a baffle 13 is formed between the baffle plate 13 and the inner wall of the pond body 1. ...

Abstract

The invention relates to an filtering pool, includes a square pool, multichip unit filters arranged in the pool, a first clapboard, a second clapboard, a third clapboard connected in turns in the pool, the first clapboard is erected in between a water outlet end and end of the multichip unit filters, the second clapboard is supported on bottom of the multichip unit filters and kept space from bottom of the pool, filter bracket of each unit filter includes a substrate and a frame-type lateral plate, filtration medium is lied on external surface of the frame-type lateral plate and the substrate on the bottom is provided with at least one purified water outlet, and position on the second clapboard corresponding to each purified water outlet is provided with purified water outlet. Comparing with the prior art, the invention applies combination of unit filter processing units, capable of setting processing units flexibly according to processing capacity. The invention provides advantages of low energy consumption, filter screen with small pore diameter, abrasion-resistance, high fltering speed, good water quality, high processing efficiency, easy replacement and low cost.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a filter tank adopting a cross-flow filtration method. Background technique [0002] At present, the filter tanks used to treat cooling water and waste water mostly use rotary disc filters. For example, the Chinese utility model patent "Fiber Rotary Disc Filter for Advanced Sewage Filtration Treatment" with patent number 200720173409.9 (notification number CN201085959Y) is disclosed A rotary disc filter. Its pool body is composed of a sewage pool and a clean water pool, which are connected to each other. The hollow water outlet shaft is fixed in the sewage pool and connected to the transmission mechanism. The rotating filter disc is fixed relatively to the hollow water outlet shaft through a hexagonal connector. The ring is equipped with an outer pressure plate, and the suction cup of the filter cloth anti-suction device is fixed on the side of the rotating filter disk ...
