Electrocoagulation device

#The present invention relates to a pollutant treatment device for water treatment, and more specifically, to an electrocoagulation device configured to effectively remove pollutants contained in raw water using the electrocoagulation principle and reduce an amount of power consumption.

#Water pollution due to nitrate is caused by industrial wastewater and excessive use of chemical fertilizers in agricultural areas. When nitrogen-containing compounds are introduced into water, water quality degradation such as eutrophication occurs in the water. In addition, when a person ingests the water containing the nitrogen-containing compounds, the nitrogen-containing compounds can cause health disturbances such as cancer, cyanosis, and the like.

#Nowadays, methods for removing nitrate from wastewater include an ion exchange resin method, a biodegradation method, a reverse osmosis method, and a catalyst denitrification method. The ion exchange resin method has a process which is useful for treating groundwater but leaves a number of residual components which are unnecessary in treated water, and the biodegradation method has a process which is useful for treating surface water but has a disadvantage in that a long treatment time period is generally required. In addition, the method using reverse osmosis or electrodialysis can achieve a nitrate removal efficiency of about 65% but has a disadvantage in that a cost of energy input is high.

#FIG. 1 is a schematic view illustrating an electrocoagulation device according to one embodiment of the present invention.

#FIG. 2 is an exploded view of FIG. 1.

#FIG. 3 is a view illustrating a state in which an accommodation member is filled with conductive masses in FIG. 1 when viewed from above.

#Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings in order for those skilled in the art to easily perform the present invention. The present invention may be implemented in several different forms and is not limited to the embodiments described herein. Parts irrelevant to description are omitted in the drawings in order to clearly explain the present invention. In addition, components which are the same or similar to each other are assigned with the same reference numerals.

#As illustrated in FIGS. 1 and 2, an electrocoagulation device 100 according to one embodiment of the present invention includes a housing 110, an accommodation member 120, at least two electrode plates 131 and 132, and conductive masses 140.

#The housing 110 may provide a space which temporarily stores raw water which is supplied from the outside and should be treated. In the present invention, the raw water to be treated may be, without limitation, sewage, wastewater, seawater, or fresh water from which pollutants need to be removed.
