A device for removing colloidal impurities by coupling electrostatic field force with hydraulic action of multi-stage partitions

Abstract

The invention belongs to the technical field of removing colloidal impurities in raw water, and discloses a device for removing colloidal impurities by electrostatic field force coupled with hydraulic action of multi-stage partitions. The device includes a settling chamber and an electric field generating device. The settling chamber is equipped with a multi-stage diversion partition and a sewage device. The multi-stage diversion partition is an upper partition and a lower partition arranged in a staggered manner, and divides the settlement chamber into several Processing units connected to each other; water inlets and water outlets are respectively provided on both sides of the top of the settling chamber; the sewage discharge device is provided at the bottom of the processing unit, and the electric field generator is provided with an anode plate and a cathode plate, and the anode plate and the cathode plate are parallel to each other Set on the bottom and top of the settling chamber, the anode plate and the cathode plate are connected through an external power supply. The device utilizes the characteristics of negative charges on the surface of colloidal particles, cleverly sets up multi-stage partitions to guide flow, and forms more favorable hydraulic conditions, so that colloidal particles can be in more favorable conditions for settlement, improve the settling efficiency of colloidal impurities, reduce consumption, and operate The process realizes automatic mud discharge.

Description

A device for removing colloidal impurities by electrostatic field force coupling multi-stage separator hydraulic action technical field The invention belongs to the technical field of colloidal impurity removal in raw water, more specifically, relate to a kind of electrostatic field force coupling It is a device for removing colloidal impurities by hydraulic action of stage separators. Background technique [0002] The impurities in raw water can be divided into solutes, colloids and suspended solids according to size. Solutes are true solutions ions or molecules. The particles of suspended matter are larger, when the water is still, the suspended matter with smaller density floats on the surface of the water, and the suspended matter with higher density sinks. Therefore, it is better to remove such impurities. Colloidal particles are mainly inorganic substances such as fine sediment, minerals, and organic substances such as humus. A substance is a collection of man...

AI Technical Summary

Problems solved by technology

The flocs formed after coagulation still need to be set up in a sedimentation tank for gravity sedimentation removal. The area of ​​the sedimentation tank is quite large, and the current land use situation is tense and expensive

To sum up, the existing traditional method of treating colloidal impurities in raw water mainly adopts the method of coagulation treatment to remove colloidal impurities. Although the removal effect can be achieved, the process is tedious and cumbersome, and it is easy to cause secondary pollution and generate too much pollution. Mud, increasing the burden on the environment
