Embodiment 1

[0020] refer to Figure 1-3 , a kind of water treatment equipment of multistage filtration, comprises base 1, and the top of base 1 is fixedly installed with sedimentation tank 2, and the inner wall of one side of sedimentation tank 2 is fixedly installed with drainage pipe 9, and one end of drainage pipe 9 runs through sedimentation tank 2 One side of the sedimentation tank 2 extends to one side of the sedimentation tank 2, the filter frame 6 can be detached from the movable card on the inner wall of both sides of the sedimentation tank 2, and the top of the filter screen 6 is located directly below the sewage pipe 9, and the top of the base 1 is fixed An adsorption chamber 10 with an opening on the top is installed, and the interior of the adsorption chamber 10 is connected to the interior of the sedimentation tank 2 in a sealed manner. The interior of the adsorption chamber 10 is provided with an adsorption assembly. The top of the base 1 is fixedly equipped with an ionizati...

Embodiment 2

[0022] Make following further improvement on the basis of embodiment one:

[0023] In the present invention, in order to facilitate the filtration of impurities in papermaking sewage, backing plates 3 are fixedly installed on the inner walls of both sides of the sedimentation tank 2, and both sides of the filter frame 6 are fixedly installed with limiting plates 4, two limiting plates The bottom of 4 is fixedly installed with the board 5, and the tops of the two backing boards 3 are provided with slots, and the bottoms of the two boards 5 respectively extend to the inside of the two slots and can be separated from the two slots respectively. Movably clamped, the filter screen 7 is fixedly installed on the bottom inner wall of the filter screen 6.

[0024] In the present invention, in order to facilitate the detachment of the filter frame 6 and the sedimentation tank 2, the tops of the two backing plates 3 are fixedly equipped with L-shaped pull rods 8, and the bottoms of the t...

Abstract

The invention belongs to the field of water treatment equipment, in particular to water treatment equipment with a multi-stage filtering function. In order to solve the problems that in existing multi-stage filtration papermaking sewage treatment equipment, large particles are precipitated in a sedimentation tank, subsequent sediment cleaning wastes time and labor, and impurities in papermaking sewage are inconvenient to further adsorb, the invention provides the following scheme. The equipment comprises a base, wherein a sedimentation tank is fixedly mounted at the top of the base; a sewage discharge pipe is fixedly mounted on the inner wall of one side of the sedimentation tank; one end of the blow-off water pipe penetrates through one side of the sedimentation tank and extends to one side of the sedimentation tank; compared with multi-stage filtering water treatment equipment, the multi-stage filtering water treatment equipment has the advantages that impurities residing in the filtering frames can be conveniently cleaned, the cleaning efficiency is high, the adsorption effect on papermaking sewage is good, and metal ions in the papermaking sewage can be effectively removed.

Description

technical field [0001] The invention relates to the technical field of water treatment equipment, in particular to a multi-stage filtering water treatment equipment. Background technique [0002] Water treatment equipment with multi-stage filtration function. Water treatment methods include physical treatment and chemical treatment. Humans have been treating water for quite a long time. Nowadays, equipment can be directly used to purify water through layer-by-layer filtration. This kind of equipment is called water treatment equipment; the existing water treatment equipment with multi-stage filtration function has certain disadvantages when used. [0003] In the existing multi-stage filter papermaking wastewater treatment equipment, large particles are deposited inside the sedimentation tank, and the subsequent cleaning of the sediment is time-consuming and laborious, and it is inconvenient to further adsorb impurities in the papermaking wastewater, so we propose a A multi-...
