Description
본 발명은 세탁기로부터 배출되는 세탁폐수의 처리장치에 관한 것으로, 특히 세탁기내에 전기화학적 처리장치를 설치하고, 세탁후 폐수를 하수로 방류하기 이전에 세탁기에서 세탁후 배수와 동시에 정화시킴으로써, 세탁폐수로 인한 수질오염을 방지할 수 있는 세탁기의 폐수 정화장치에 관한 것이다.The present invention relates to an apparatus for treating laundry wastewater discharged from a washing machine, and more particularly, by installing an electrochemical treatment device in a washing machine and purifying the wastewater at the same time with the drainage after washing in a washing machine before discharging the wastewater to sewage. It relates to a waste water purification device of a washing machine that can prevent water pollution caused by.
일반적으로 합성세제로 인한 수질오염 문제는 자체 하수처리시설을 갖추지 못한 도시의 가정등에서 무제한적으로 배출되는 생활하수가 하천으로 유입되어 발생된다. 특히, 환경부가 발표한 1994년도 환경백서에 의하면, 생활하수는 주방 27%, 세탁 30%, 목욕탕 25%, 세면 및 화장실 8%, 청소 및 기타 10%로 이중 세탁에 사용된 물이 가장 많다. 이러한 세탁폐수 중에서 25%는 자체 자정작용에 의하여 정화되지만 그 나머지 75%는 그대로 하천에 유입되고 있다.In general, the problem of water pollution caused by synthetic detergents is caused by the inflow of living sewage into the river, which is discharged from households in cities that do not have their own sewage treatment facilities. In particular, according to the 1994 Environmental White Paper published by the Ministry of Environment, household sewage is 27% kitchen, 30% laundry, 25% bathroom, 8% toilet and toilet, 8% cleaning and other 10% water used for double washing. 25% of these wastewaters are purified by self-cleaning, but the remaining 75% are still flowing into the stream.
상기와 같은 합성세제로 인한 수질오염 문제와 관련하여, 하수처리 과정에서의 합성세제처리가 연구되었지만, 합성세제의 사용후 상수처리 전단계에서 직접적인 처리에 관한 기술은 발표된 바가 없다. 특히, 합성세제 사용량의 많은 부분을 차지하는 세탁의 경우 세탁후 폐수를 직접처리하는 기술은 발표된 바가 없다.In relation to the water pollution problem caused by the synthetic detergents described above, the synthetic detergent treatment in the sewage treatment process has been studied, but there is no description of a technique for the direct treatment in the pre-use water treatment stage. In particular, in the case of laundry, which takes up a large part of the amount of synthetic detergent, a technique for directly treating wastewater after washing has not been published.
그런데, 세탁폐수는 일단 하천으로 방류되면 일반적인 하수처리에 의하여 처리되므로 세탁폐수만의 효율적인 처리는 불가능하게 된다. 그러므로, 세탁폐수가 세탁기로부터 방류되기 이전에 정화처리하는 기술이 요구되고 있다.However, since the laundry wastewater is discharged to the river, it is treated by a general sewage treatment, and thus, it is impossible to efficiently process the laundry wastewater only. Therefore, there is a need for a technique for purifying washing wastewater before it is discharged from the washing machine.
상기와 같은 종래의 세탁폐수 처리문제를 해결하기 위하여, 본 발명은 세탁기내에 전기화학적 처리장치를 설치하고, 세탁후 폐수를 하수로 방류하기 이전에 세탁기에서 세탁후 배수와 동시에 정화시킴으로써, 세탁폐수로 인한 수질오염을 방지할 수 있는 세탁기의 폐수 정화장치를 제공함을 목적으로 한다.In order to solve the conventional laundry wastewater treatment problem as described above, the present invention by installing an electrochemical treatment device in the washing machine, and by purifying at the same time with the drain after washing in the washing machine before discharged to the sewage after washing, It is an object of the present invention to provide a wastewater purification device of a washing machine that can prevent water pollution.
상기 목적을 달성하기 위하여 본 발명은 세탁조로부터 배수관을 통하여 배출되는 폐수량을 조절하기 위한 플로메터와; 그 플로메터를 통하여 인가된 세탁폐수를 전기분해하는 다수의 전극을 구비한 폐수처리부와; 그 폐수처리부에 구비된 전극에 전원을 인가하고, 상기 플로메터의 개폐를 제어하는 제어부;를 구비함을 특징으로 한다.In order to achieve the above object, the present invention includes a flowmeter for adjusting the amount of waste water discharged from the washing tank through the drain pipe; A wastewater treatment unit having a plurality of electrodes for electrolyzing the laundry wastewater applied through the flowmeter; And a control unit for applying power to an electrode provided in the wastewater treatment unit and controlling opening and closing of the flow meter.

이하, 본 발명의 바람직한 실시예를 첨부된 도면을 참조하여 설명한다.Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.
도 1을 참조하면, 본 발명에 적용되는 세탁기(10)는 세탁과정에서 발생된 폐수가 담져진 세탁조(11)와, 그 세탁조(11)로부터 배수관을 거쳐 배출된 세탁폐수를 전기분해하여 외부로 배출하는 폐수처리부(12),(13),(14),(15)를 구비한다.Referring to FIG. 1, the washing machine 10 applied to the present invention electrolyzes the washing tank 11 in which the waste water generated during the washing process is contained, and the laundry waste water discharged from the washing tank 11 through a drain pipe. The wastewater treatment parts 12, 13, 14, and 15 are discharged.
도 2를 참조하면, 상기 세탁조(11)와 상기 폐수처리부(12) 사이에는 세탁폐수의 2배수량을 조럴하기 위한 플로메터(flowmeter)(20)가 설치된다. 마찬가지로, 그 나머지 폐수처리부(13),(14),(15)에도 상기와 같은 플로메터(20)가 설치된다.Referring to FIG. 2, a flowmeter 20 is installed between the washing tank 11 and the wastewater treatment unit 12 to control twice the amount of the washing wastewater. In the same manner, the remaining wastewater treatment units 13, 14, and 15 are provided with the above-mentioned flowmeter 20.
또한, 상기 폐수처리부(12)는 상기 플로메터(20)를 통하여 상기 세탁조(11)로부터 인가되는 세탁폐수를 전기분해하여 정화시키고, 서로 격자형태로 배치된 복수개의 전극(12a),(12b)과, 그 전극(12a),(12b)들을 통과하면서 정화된 물을 외부로 배출하는 배출구(12c)를 구비한다.In addition, the wastewater treatment unit 12 electrolyzes and cleans the laundry wastewater applied from the washing tank 11 through the flowmeter 20, and includes a plurality of electrodes 12a and 12b disposed in a lattice form. And a discharge port 12c for discharging the purified water to the outside while passing through the electrodes 12a and 12b.
상기 폐수처리부(12)의 전극들(12a),(12b)은 세탁기의 동작을 제어하는 제어부(미도시)로부터 전원을 공급받아 세탁폐수를 전기분해하고, 아울러 상기 플로메터(20)의 개폐정도도 상기 제어부에 의하여 제어된다.Electrodes 12a and 12b of the wastewater treatment unit 12 are supplied with power from a controller (not shown) that controls the operation of the washing machine to electrolyze the laundry wastewater, and also to open and close the flowmeter 20. It is also controlled by the control unit.
상기 폐수처리부(12)의 전극들(12a),(12b)은 알루미늄 전극을 이용하고, 세탁폐수를 지그재그로 흐르도록 함으로써 세탁폐수의 접촉시간을 길게하기 위하여 도 3과 같이, 격자형태로 배치된다.The electrodes 12a and 12b of the wastewater treatment unit 12 are disposed in a lattice form as shown in FIG. 3 to increase the contact time of the laundry wastewater by using aluminum electrodes and allowing the laundry wastewater to flow in a zigzag. .
상기 폐수처리부(12) 이외의 다른 폐수처리부(13),(14),(15)는 상기 폐수처리부(12)와 동일하게 구성된다.Other wastewater treatment units 13, 14, and 15 other than the wastewater treatment unit 12 are configured in the same manner as the wastewater treatment unit 12.
본 발명에 따른 폐수 처리장치는 각각 10L의 처리용량을 갖는 4개의 폐수처리부(12),(13),(14),(15)를 포함하지만, 세탁기 배수량인 80L를 처리하기 위하여는 4개의 폐수처리부가 더 구비할 수 있다.The wastewater treatment apparatus according to the present invention includes four wastewater treatment units 12, 13, 14, and 15 each having a treatment capacity of 10L, but four wastewaters are disposed to treat 80L, which is a washing machine drainage. The processing unit may be further provided.
이와 같은 폐수처리부(12),(13),(14),(15)들을 세탁기 내부에 장착하기 위하여는 그 무게가 가벼워야 하고, 세탁기내에 공간이 요구된다. 본 발명에 따른 폐수 처리장치에 있어서, 도 1의 폐수처리부(12),(13),(14),(15)들은 세탁기(10)의 하측 및 양쪽측면의 공간에 장착될 수 있다.In order to mount such wastewater treatment parts 12, 13, 14, and 15 inside the washing machine, the weight thereof should be light and space is required in the washing machine. In the wastewater treatment apparatus according to the present invention, the wastewater treatment units 12, 13, 14, and 15 of FIG. 1 may be mounted in spaces on the lower side and both sides of the washing machine 10.
즉, 실제 세탁기의 아래쪽 공간은 약 33000cm3정도이고, 본 발명의 실시예에 있어서 폐수처리부(12)는 16cm × 15cm × 16cm의 크기를 가지므로, 폐수처리부(12)는 3960cm3정도의 공간을 차지한다. 따라서, 폐수처리부(12)와 같은 폐수처리부가 8개 구비될 경우 요구되는 여유공간은 31680cm3이므로, 80L의 세탁폐수를 처리할 수 있는 페수 처리장치가 세탁기내부에 장착될 수 있다.That is, the space below the actual washing machine is about 33000 cm 3 , and in the embodiment of the present invention, since the wastewater treatment unit 12 has a size of 16 cm × 15 cm × 16 cm, the waste water treatment unit 12 has a space of about 3960 cm 3 . Occupy. Therefore, when eight wastewater treatment units such as the wastewater treatment unit 12 are provided, since the required free space is 31680 cm 3 , a wastewater treatment apparatus capable of treating 80L of laundry wastewater may be mounted in the washing machine.
또한, 일반적으로 세탁기(10)의 배수는 자연배수라는 점을 감안하여 본 발명에 따른 폐수 처리장치는 세탁조(11)의 하단에 설치된다.In addition, in general, the wastewater treatment apparatus according to the present invention is installed at the bottom of the washing tank 11 in consideration of the fact that the drainage of the washing machine 10 is a natural drainage.
그리고, 상기 전극(12a),(12b)에서의 전기분해 반응정도는 전극면적에 의하여 좌우되므로, 전극면적이 넓게 구현되도록 폐수처리부(12),(13),(14),(15)의 높이 및 길이는 여유공간에 따라 변형될 수 있다.In addition, since the degree of electrolysis reaction at the electrodes 12a and 12b depends on the electrode area, the heights of the wastewater treatment units 12, 13, 14, and 15 are implemented so that the electrode area is wide. And the length can be modified according to the clearance.
또한, 폐수처리부(12)의 무게는 2.3Kg이고, 전극(12a),(12b)은 각각 128g의 무게를 갖는다.In addition, the weight of the wastewater treatment unit 12 is 2.3Kg, and the electrodes 12a and 12b each have a weight of 128g.
또한, 전극(12a),(12b)은 알미늄대신에 얇은 박막재료를 이용하여 구현하고, 전극(12a),(12b)간의 거리를 조금 짧게 함으로써 폐수 처리장치의 무게를 줄일 수 있다.In addition, the electrodes 12a and 12b may be implemented using a thin film material instead of aluminum, and the weight of the wastewater treatment apparatus may be reduced by shortening the distance between the electrodes 12a and 12b.
상기와 같이 구성되는 세탁기의 폐수처리 장치에 있어서, 세탁조(11)에 담긴 세탁폐수는 플로메터(20)를 통하여 폐수처리부(12)로 유입된다. 이때, 제어부는 전극(12a),(12b)에 전원을 공급하여 전극(12a),(12b)에 닿는 세탁폐수가 전기분해되도록 한다.In the wastewater treatment apparatus of the washing machine configured as described above, the laundry wastewater contained in the washing tank 11 is introduced into the wastewater treatment unit 12 through the flowmeter 20. At this time, the control unit supplies power to the electrodes 12a and 12b so that the laundry wastewater touching the electrodes 12a and 12b is electrolyzed.
폐수처리부(12)에 유입된 세탁폐수는 도 3과 같이, 격자형태로 배치된 전극(12a),(12b)사이를 지그재그로 흐르게 된다. 이와 같이 세탁폐수가 전극(12a),(12b)에 접촉하는 시간을 길게 함으로써, 전기분해 시간을 길게 하여 정화효율을 높일 수 있다.The laundry wastewater introduced into the wastewater treatment unit 12 flows zigzag between the electrodes 12a and 12b arranged in a lattice form as shown in FIG. 3. Thus, by lengthening the time which wash | cleaning wastewater contacts the electrodes 12a and 12b, electrolysis time can be lengthened and purification efficiency can be improved.
도 4를 참조하면, 본 발명에 따른 폐수 정화장치에 의하여 세탁폐수가 전기분해됨으로써, 세탁폐수의 생화학적산소요구량(이하, COD)이 제거됨을 알 수 있다.Referring to Figure 4, it can be seen that by washing the wastewater by the wastewater purification apparatus according to the present invention, the biochemical oxygen demand (hereinafter, COD) of the laundry wastewater is removed.
일반적으로, 환경공학적 폐수처리공정에서는 COD, pH, 부유물질(SS), 음이온계면활성제(Surfactant), 노르말핵산(n-Hexane), 전기전도도(Conductivity)등을 분석대상으로 하고 있는데, 도 4에서는 COD제거율만을 일예로서 도시하였다. 그러나, 본 발명에 따르면 COD이외의 상기 분석대상들도 크게 향상시킬 수 있음을 확인하였고, 지면상의 제약으로 인하여 다른 데이타 그래프는 도시하지 않는다.In general, in the environmental engineering wastewater treatment process, COD, pH, suspended solids (SS), anionic surfactants (Surfactant), normal nucleic acid (n-Hexane), electrical conductivity (Conductivity), etc. are analyzed. Only COD removal rate is shown as an example. However, according to the present invention, it was confirmed that the analytes other than COD can be greatly improved, and other data graphs are not shown due to the limitation of the paper.
상기와 같이 본 발명은 세탁기 내부에 세탁폐수를 전기분해할 수 있는 폐수 정화장치를 구비하고, 상기 폐수 정화장치에는 전기분해를 위한 다수의 전극(12a),(12b)을 격자형태로 배치함으로써, 세탁폐수가 전극(12a),(12b)에 접촉하는 시간을 길게하여 세탁폐수의 정화효율을 높일 수 있다. 그러므로, 본 발명에 의하면 세탁후 폐수를 하수로 방류하기 이전에 세탁기에서 세탁후 배수와 동시에 정화시킴으로써, 세탁폐수로 인한 수질오염을 방지할 수 있다.As described above, the present invention includes a wastewater purification apparatus capable of electrolyzing laundry wastewater in a washing machine, and in the wastewater purification apparatus, a plurality of electrodes 12a and 12b for electrolysis are disposed in a lattice form. It is possible to increase the purification efficiency of the laundry wastewater by lengthening the time for which the laundry waste water contacts the electrodes 12a and 12b. Therefore, according to the present invention, by purifying at the same time as the drainage after washing in the washing machine before discharge of the wastewater after washing into sewage, it is possible to prevent water pollution due to the washing wastewater.
