본 발명은 역삼투막과 전기산화법을 이용한 무방류 정수장치에 관한 것으로, 더 상세하게는 역삼투막을 세척하여 오염 및 막힘을 방지하고, 전기산화법을 사용하여 방류되지 않고 정수할 수 있도록 하는 역삼투막과 전기산화법을 이용한 무방류 정수장치에 관한 것이다. The present invention relates to a zero discharge water purification device using a reverse osmosis membrane and an electrooxidation method. A non-discharge water purifying apparatus.

일반적으로, 농촌의 소규모 마을 부락 단위로 간이급수시설을 이용하여 각 가정에 급수를 하고 있는데 축산폐수나, 비료 등의 과다 사용으로 물속에 질산성질소가 검출되거나 지형상의 이유로 수중에 불소이온이 과량 검출되므로 식수로 사용되기에는 부적합한 경우가 많다. 이렇게 물에 오염된 질산성질소나 불소이온 등을 제거하기 위하여 이온교환수지를 사용한 흡착방식이나 역삼투압방식에 의한 정수 시스템을 사용하게 된다. In general, small households in rural villages are using simple water supply facilities to supply their households. Nitrogenous nitrogen is detected in the water due to excessive use of livestock wastewater and fertilizers, or excessive fluoride ions are present in the water for geological reasons. It is often unsuitable to be used as drinking water because it is detected. In order to remove nitrate nitrogen and fluorine ions contaminated with water, an adsorption method using an ion exchange resin or a water purification system using a reverse osmosis method is used.

특히, 역삼투압방식은 농촌의 연령고령화에 따른 관리 문제로 인해 관리가 용이하여 주로 사용하게 된다. In particular, reverse osmosis is mainly used because of the management problems caused by the aging of rural areas.

역삼투여과막을 이용한 정수장치는 일정 수압으로 한쪽을 가압하여 물 분자만이 역삼투막을 투과시키게 되고, 역삼투막의 미세기공을 통하여 오염물질을 여과시키는 원리를 이용하게 된다. 이러한 역삼투여과막을 이용한 정수장치는 분자량이 커서 막을 투과하지 못하는 오염물질이 함유된 일정한 양의 퇴수를 방류시켜야 하는 문제점이 있었다. 이러한 퇴수의 방류로 인하여 전력을 더 소모하게 되며 일정한 양의 퇴수를 방류하여야 하므로 물의 낭비를 가져오는 문제점이 있었다. The water purification device using a reverse osmosis membrane presses one side at a certain water pressure so that only water molecules permeate the reverse osmosis membrane, and utilizes the principle of filtering contaminants through the micropores of the reverse osmosis membrane. Such a water purification device using a reverse osmosis membrane has a problem in that a large amount of water discharges a contaminant containing a contaminant that cannot penetrate the membrane. Due to the discharge of the discharge, there is a problem in that more power is consumed and waste water is discharged because a certain amount of discharge must be discharged.

또한 역삼투막을 장기간 사용하게 되면 경도유발물질에 의한 스케일이나 탁도 유발 물질에 의한 오염물질로 의한 성능 저하현상이 발생하게 된다. 이러한 스 케일은 시간이 가면 갈수록 굳어져서 시간이 지나면 제거하기 어렵게 되는 문제점이 있었다. In addition, when the reverse osmosis membrane is used for a long time, performance degradation due to the scale caused by the hardness-inducing substance or the contaminants caused by the turbidity-inducing substance occurs. These scales become harder with time, and thus have a problem of being difficult to remove over time.

따라서, 퇴수의 방류로 인한 물의 낭비를 없애고 오염물질을 제거하여 정수효율이 저하되는 것을 방지하기 위한 역삼투여과막을 이용한 정수장치의 개발이 요구되고 있다.

도 1은 본 발명에 따른 무방류 정수장치의 개략적인 구성을 나타낸 도면이다.1 is a view showing a schematic configuration of a zero discharge water purifying apparatus according to the present invention.

도시된 바와 같이, 본 발명의 역삼투막과 전기산화를 이용한 정수장치은, 관정펌프(10)에 의해 원수가 공급되어 1차 정수되도록 하는 전처리필터(20)와, 상기 전처리필터(20)와 연결되어 2차 정수되도록 하는 역삼투막필터(30)와, 상기 역삼투막필터(30)에서 미처리된 퇴수를 처리하며 전해작용으로 전기분해되어 정화되도록 하는 전기산화조(40)와, 상기 역삼투막필터(30)를 거친 2차 정수가 분기되어 처리수라인(80)으로 공급시키는 분기부(50)와, 상기 분기부(50)와 연결되어 상기 역삼투막필터를 거친 2차 정수가 일부 저장되도록 하는 청수탱크(60)와, 상기 전처리필터(20)와 역삼투막필터(30) 사이에 위치하며 압력강하시 또는 세척시 작동되어 역삼투막필터(30)로 펌핑하도록 하는 고압펌프(70)로 구성된다. As shown, the water purification device using the reverse osmosis membrane and the electrooxidation of the present invention, the pre-treatment filter 20 so that the raw water is supplied by the well pump 10 and the primary water purification, and is connected to the pre-treatment filter 20 Reverse osmosis membrane filter 30 to purify the water, an electrooxidation tank 40 to treat the untreated sewage from the reverse osmosis membrane filter 30 to be electrolyzed and purified by electrolytic action, and the reverse osmosis membrane filter 30 A branch 50 for supplying the purified water to the treated water line 80 and a fresh water tank 60 connected to the branch 50 so that the secondary purified water passed through the reverse osmosis membrane filter is partially stored; Located between the pretreatment filter 20 and the reverse osmosis membrane filter 30 is composed of a high pressure pump 70 to be operated when the pressure drop or washing to pump to the reverse osmosis membrane filter (30).

상기 전처리필터(20)는 관정펌프(10)에 의해 원수가 공급되어 1차 정수되도록 하는 역할을 한다. 상기 전처리필터(20)에서 필터링된 1차 정수는 상기 역삼투막필터(30)와 상기 전기산화조(40)로 각각 이동되게 된다. The pretreatment filter 20 serves to ensure that the raw water is supplied by the well pump 10 to the primary water purification. The primary purified water filtered by the pretreatment filter 20 is moved to the reverse osmosis membrane filter 30 and the electrooxidation tank 40, respectively.

상기 역삼투막필터(30)는 공급되는 물을 진동시켜 막힘을 방지하도록 하는 초음파 진동자(31)가 구비되고 상기 전처리필터(20)와 연결되어 2차 정수되도록 한다. 상기 역삼투막필터(30)에서 필터링된 2차 정수는 바로 사용하게 되며 이중 일부를 청수탱크(60)로 공급되어 저장되게 된다. 이 청수탱크(60)에 저장된 2차 정수는 역삼투막필터(30) 세척시 사용하게 된다. The reverse osmosis membrane filter 30 is provided with an ultrasonic vibrator 31 to vibrate the supplied water to prevent clogging, and is connected to the pretreatment filter 20 so as to be secondary purified. The secondary purified water filtered by the reverse osmosis membrane filter 30 is used immediately, and some of them are supplied to the fresh water tank 60 to be stored. The secondary purified water stored in the fresh water tank 60 is used when the reverse osmosis membrane filter 30 is washed.

상기 전기산화조(40)는 상기 역삼투막필터(30)에서 미처리된 퇴수를 처리하며 활성탄소가 충전되어 유입된 1차 정수를 활성탄소의 전해작용으로 전기분해되어 정화되도록 하는 역할을 한다. 상기 전기산화조(40)에 의한 전기산화법은 한국등록특허 제0436982호와 같은 방법을 사용하게 된다. 상기 방법은 실린더 내부에 충전된 활성탄소에 의한 흡착과 흡착된 물질의 전기화학적 분해에 의한 처리를 하게 된다. 또한, 이 전기산화법은 전해조에 220볼트의 교류전원을 인가하여 물속의 질산 성질소와 같은 이온들을 환원을 통해 질소로 변화시켜 공기 중으로 내보내게 된다. The electrolytic oxidizer 40 serves to treat untreated sewage from the reverse osmosis membrane filter 30 and to electrolyze and purify the primary purified water filled with activated carbon by electrolytic action of activated carbon. The electrooxidation method by the electrooxidation tank 40 is to use the same method as the Korean Patent No. 0438982. The method is treated by adsorption by activated carbon charged in the cylinder and electrochemical decomposition of the adsorbed material. In addition, this electro-oxidation method applies 220 volts of alternating current power to the electrolyzer to convert ions such as nitrate in water into nitrogen through reduction and release it into the air.

역삼투막을 이용한 정수장치의 단점은 막을 통과하지 못한 이온들 즉 농축수를 퇴수로 버려야 한다. 이렇게 되면 물을 버려야 하는 문제와 버린 만큼 물을 더 처리하게 되어 에너지 비용도 그 만큼 상승하게 된다. 본 발명에서는 이러한 문제점을 개선하여 이 버려지는 퇴수를 다시 전기산화법에 의해 재처리하는 것이다. 퇴수를 재처리하여 다시 처리수라인(80)으로 보내주면 퇴수를 전혀 내보내지 않는 역삼투압방식을 사용한 무방류 정수장치가 된다. 이와 같이, 이 버려지는 퇴수를 활용하기 위해 퇴수를 전기 산화법에 의해 재처리 하게 되면 퇴수를 방류하지 않게 되어 물을 절약할 수 있게 된다. Disadvantages of the water purification system using a reverse osmosis membrane are the discharge of ions that have not passed through the membrane, that is, the concentrated water. This causes the problem of having to throw out the water and the disposal of more water, thus increasing energy costs. In the present invention, this problem is improved and the wastewater discharged is reprocessed by electrooxidation again. When the wastewater is reprocessed and sent back to the treated water line 80, the dischargeless water purification device using the reverse osmosis method does not discharge the wastewater at all. As such, when the wastewater is reprocessed by the electrooxidation method in order to utilize the discarded wastewater, the wastewater is not discharged and water can be saved.

상기 분기부(50)는 상기 역삼투막필터(30)를 거친 2차 정수가 분기되어 처리수라인(80)으로 공급시키는 역할을 한다. 이때, 상기 분기부(50)로부터 일부는 상기 청수탱크(60)로 공급되게 된다. The branch 50 serves to supply the treated water line 80 by branching the secondary purified water passing through the reverse osmosis membrane filter 30. At this time, a part of the branch 50 is supplied to the fresh water tank 60.

상기 청수탱크(60)는 상기 분기부(50)로부터 상기 역삼투막필터(30)를 거친 2차 정수가 분기되어 저장되게 되며 이 2차 정수가 역삼투막필터(30) 세척시 사용되게 된다. 상기 청수탱크(60)의 인입라인에 볼탑(61)을 설치하여 역삼투막필터(30)를 통과한 청수가 청수탱크에 일정 수위가 되기까지 채워지고, 채워진 후에는 볼탑(61)으로 인해 더 이상 청수탱크(60)로 들어가지 않고 처리수라인(80)을 따라 처리조에 들어가게 된다. The fresh water tank 60 is the secondary purified water passed through the reverse osmosis membrane filter 30 is stored from the branch 50 is stored and the secondary purified water is used when washing the reverse osmosis membrane filter (30). The ball top 61 is installed in the inlet line of the fresh water tank 60 so that the fresh water passing through the reverse osmosis membrane filter 30 is filled to the fresh water tank to a certain level, and after it is filled, the water is no longer fresh due to the ball tower 61. The tank 60 enters the treatment tank along the treatment water line 80 without entering the tank 60.

또한 역삼투막을 장기간 사용하게 되면 경도유발물질에 의한 스케일이나 탁도 유발 물질에 의한 오염물질로 의한 성능 저하현상이 발생되게 되며, 이 스케일 은 시간이 가면 갈수록 굳어져서 시간이 지나면 제거하기 어려우므로, 이 문제를 해결하기 위한 방법은 매일 세척하는 방법이다. 본 발명은 역삼투막필터(30)에 스케일이 끼지 않도록 매일 역삼투막필터(30)를 통과한 청수로 세척하도록 하는 것이 특징이다. 이에 따라 상기와 같은 세척을 위해 초음파와 청수에 의한 세척시스템을 이용하여 역삼투막의 오염을 막아 장기간 사용이 가능하게 된다. In addition, if the reverse osmosis membrane is used for a long period of time, performance deterioration may occur due to the scale caused by the hardness-inducing substance or the contaminants caused by the turbidity-inducing substance, and this scale becomes harder as time passes and it is difficult to remove it as time passes. To solve the problem is how to wash every day. The present invention is characterized in that it is washed with fresh water passing through the reverse osmosis membrane filter 30 so that the scale does not become stuck in the reverse osmosis membrane filter 30. Accordingly, it is possible to use for a long time by preventing the contamination of the reverse osmosis membrane by using a cleaning system by ultrasonic and fresh water for the cleaning as described above.

청수탱크라인(62)에는 역삼투막필터(30) 세척시 상기 고압펌프(70) 작동과 연동되는 솔레노이드 밸브(63)가 구비되어 있다. 역삼투막필터(30) 세척시에 상기 고압펌프(70)가 작동되게 되면 상기 솔레노이드 밸브(63)가 열리게 되어 역삼투막필터(30)로 공급되게 되게 되며, 고압펌프(70)의 작동이 정지되면 솔레노이드 밸브(63)가 닫히게 된다. The fresh water tank line 62 is provided with a solenoid valve 63 interlocked with the operation of the high pressure pump 70 when the reverse osmosis membrane filter 30 is cleaned. When the high pressure pump 70 is operated when the reverse osmosis membrane filter 30 is cleaned, the solenoid valve 63 is opened to be supplied to the reverse osmosis membrane filter 30. When the operation of the high pressure pump 70 is stopped, the solenoid valve is stopped. 63 is closed.

상기 청수탱크(60)는 상기 역삼투막필터(30) 세척 후 세척된 물을 배수되도록 하는 드레인밸브(64)가 구비된다. 상기 청수탱크(60)에서 공급된 청수가 역삼투막필터(30)을 세척하고 다시 청수탱크로 유입되게 되는데, 상기 드레인밸브(64)는 이 세척된 물을 배수되도록 한다. 이때, 드레인밸브(64)는 역삼투막필터(30) 세척후 고압펌프(70)의 작동이 멈추면 배수되도록 한다. The fresh water tank 60 is provided with a drain valve 64 to drain the washed water after washing the reverse osmosis membrane filter (30). The fresh water supplied from the fresh water tank 60 washes the reverse osmosis membrane filter 30 and flows back into the fresh water tank. The drain valve 64 allows the washed water to be drained. At this time, the drain valve 64 is drained when the operation of the high-pressure pump 70 after the reverse osmosis membrane filter 30 is washed.

상기 고압펌프(70)는 상기 전처리필터(20)와 역삼투막필터(30) 사이에 위치하며 압력강하시 또는 세척시 작동되어 역삼투막필터(30)로 펌핑하도록 한다. 세척시에는 청수탱크(60)에 저장된 청수를 역삼투막필터(30)로 펌핑하여 역삼투막필터(30)를 세척하도록 하며 전단과 후단에 각각 저압센서(71) 및 고압센서(72)가 구비되어 있다. The high pressure pump 70 is located between the pretreatment filter 20 and the reverse osmosis membrane filter 30 and operated at a pressure drop or washing to pump the reverse osmosis membrane filter 30. At the time of washing, the fresh water stored in the fresh water tank 60 is pumped by the reverse osmosis membrane filter 30 to wash the reverse osmosis membrane filter 30, and the low pressure sensor 71 and the high pressure sensor 72 are provided at the front and rear ends, respectively.

이때, 상기 저압센서(71) 및 고압센서(72)는 상기 전처리필터(20)를 통과한 1차정수의 압력을 계측하여 소정 압력 이하일 때에 상기 관정펌프(10), 고압펌프(70) 중 어느 하나 이상을 구동시키고, 소정 압력 이상일 경우 상기 관정펌프(10), 고압펌프(70) 중 어느 하나 이상을 구동정지시키게 된다. 이와 같이, 전처리필터(20)를 통과하고 상기 저압센서(71) 및 고압센서(72)에 의해 피드백 된 1차 정수는 상기 관정펌프(10)를 통해 유입되는 원수의 압력치를 계속적으로 계측하는 바, 물이 소정 압력 이상 도달될 시에 상기 관정펌프(10) 및/또는 상기 고압펌프(70)를 작동정지 시키거나, 고출력 또는 저출력 상태로 설정하여 완급조절을 실시할 수 있도록 하여 관정펌프(10)의 공회전 방지를 실현하여 내구성을 향상할 수 있도록 함은 물론, 정수장치에서 요구되는 최적화된 압력이 항상 일정하게 유지될 수 있게 된다. At this time, the low pressure sensor 71 and the high pressure sensor 72 measures the pressure of the first constant water passing through the pre-treatment filter 20 and any of the well pump 10 and the high pressure pump 70 when the pressure is below a predetermined pressure. When one or more are driven, and the predetermined pressure or more, any one or more of the well pump 10 and the high pressure pump 70 is stopped. As such, the primary purified water passing through the pretreatment filter 20 and fed back by the low pressure sensor 71 and the high pressure sensor 72 continuously measures the pressure value of the raw water flowing through the well pump 10. When the water reaches a predetermined pressure or more, the well pump 10 and / or the high pressure pump 70 may be stopped or set to a high or low output state to perform a full adjustment to the well pump 10 It is possible to improve the durability by preventing idling, and the optimized pressure required by the water purifier can be kept constant at all times.

이상과 같이, 본 발명에 따른 정수기는, 청수(역삼투막을 통과한 수)에 의한 날마다의 역삼투막의 세정작업이 가능하므로 그 수명을 획기적으로 연장할 수 있으며, 여과막을 통과하지 못하고 버려야 하는 퇴수를 전기 산화법에 의해 재처리하여 퇴수가 전혀 없는 무폐수, 무방류 정수장치로써, 폐수의 양산을 방지하여 수자원을 효율적으로 활용할 수 있다는 등의 효과가 있다.As described above, since the water purifier according to the present invention can clean the daily reverse osmosis membrane by fresh water (water passed through the reverse osmosis membrane), the lifespan can be significantly extended, and the water discharged through the filtration membrane must be discarded without electricity. The wastewater-free and discharge-free water purification device, which is completely reprocessed by the oxidizing method, prevents mass production of the wastewater, thereby effectively utilizing water resources.
