High-alga ground water treatment device

Abstract

The invention discloses a high-alga ground water treatment device, and relates to the technical field of water treatment. The device comprises a treatment tank, and a cavity is fixedly formed in the treatment tank; the treatment tank is communicated with a water inlet pipe; the lower part of the treatment tank is communicated with a dirt discharge pipe; the inner wall of the cavity is rotationallyconnected with a filter element through a bearing; the bottom surface of the treatment tank is rotationally connected with a purified water outlet pipe through a bearing; the upper end of the purified water outlet pipe is fixedly communicated with the filter element; an inner cleaning pipe is fixedly mounted at the top of the treatment tank; the lower end of the inner cleaning pipe penetrates through the filter element and extends into the filter element; and the peripheral side surface of the inner cleaning pipe is rotationally connected with the filter element through a bearing. The designof a transmission motor and the filter element makes flocculated impurities left after flocculation of high-alga raw water rapidly separated, and the rotary design of an inner cleaning spray head andthe filter element makes the filter element rapidly remove impurities adhering to the surface of the filter element under the action of water flow and centrifugal force.

Description

technical field [0001] The invention belongs to the technical field of water treatment, in particular to a surface water treatment device with high algae content. Background technique [0002] Surface water refers to the water in rivers, lakes, and reservoirs. The surface water body is a natural gathering place for precipitation. The water that falls to the ground flows along the surface runoff, flows along the high ground to the low place, and finally gathers in the local river. to form the basin of the river. [0003] In the prior art, there are many treatment methods for raw water containing algae, but the removal of algae is not a separate process, it must be combined with other processes in the water plant such as coagulation, sedimentation, filtration and disinfection to achieve better algae removal effect , the commonly used treatment methods are as follows: (1) use microfiltration machine: the efficiency of microfiltration machine to remove algae varies greatly with...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a surface water treatment device with high algae content, which solves the problem of low service life of the existing filter devices used in the treatment of water with high algae content through the design of the inner cleaning nozzle, filter element and drive motor
