Electrocoagulation device

Abstract

An electrocoagulation device is provided. An electrocoagulation device according to an exemplary embodiment of the present invention comprises: a housing having an inner space; a containing member arranged in the inner space; at least two electrode plates arranged outside the containing member so as to face each other such that power supplied from the outside is applied thereto; and a plurality ofconductive lumps having a predetermined volume, which are contained in the containing member so as to contact each other and to form pores through which raw water can pass, wherein contaminants included in the raw water are coagulated through electrocoagulation as the same pass through the pores.

Description

technical field [0001] The invention relates to a pollutant treatment device for water treatment, and more specifically, to an electrocoagulation device capable of effectively removing pollutants contained in raw water and reducing power consumption by using the principle of electrocoagulation. Background technique [0002] Water pollution by nitrates arises from industrial effluents and excessive use of chemical fertilizers in agricultural areas. If nitrogen-containing compounds flow into water, water quality degradation such as eutrophication occurs. In addition, if a person ingests water containing nitrogen-containing compounds, health problems such as cancer, cyanosis, and the like may occur due to the nitrogen-containing compounds. [0003] Currently, as methods for removing nitrate from wastewater, there are ion exchange resins, biodegradation, reverse osmosis, electrodialysis, and catalyst denitrification methods. The ion exchange resin method is a useful process fo...

Problems solved by technology

[0006] However, in the conventional electrocoagulation method, a plurality of plate-shaped electrode plates are spaced apart and arranged between a pair of power electrodes, and thus power consumption varies depending on the relative distance from the power electrodes connected to the power supply.

Therefore, the replacement timing of the plurality of electrode plates arranged between a pair of power electrodes differs depending on the relative distance from the power electrodes, and maintenance is troublesome.

[0007] In addition, the conventional electrocoagulation method has the problems of excessive power consumption and increased production costs.
