More specifically, the present invention adsorbs and removes ammonium ions using a plurality of zeolite columns, and zeolites are Na, Ca ions, etc. It is a method for removing ammonium ions that are continuously used by substituting with a water treatment system, and a water purifying apparatus in which the inflow water from the fish farm goes through two zeolite columns and becomes a treated water in which ammonium ions are gradually removed. will be.
[종래기술][Private Technology]
일반적으로, 양어장에서의 정수처리는 강이나 저수지내에 물을 계속 유입시키고 배출시키는 것이 바람직 하지만, 이렇게 물을 계속적으로 유입, 배출시키는 경우 물의 공급량이 너무나 많아지거나 정수처리가 요구되기 때문에 현 일반적 양어장의 실정상 많은 비용이 소요되어진다.Generally, it is preferable to continuously inflow and discharge water into rivers or reservoirs, but in case of continuous inflow and outflow of water, the amount of water supplied is too high or water purification treatment is required. In reality, it costs a lot.
상기와 같이 양어장을 정수처리하는 다른 방법으로는 암모니움이온을 제거하기 위한 화학제를 살포하는 것이나, 화학적 사용에 따른 부작용과 살포된 화학제와 오염물질과의 화합으로 또 다른 이물질이 생겨 더욱 큰 오염의 문제가 야기될 수 있다.As mentioned above, another method of water treatment of fish farms is spraying a chemical to remove ammonium ions, or other foreign substances are formed due to chemical side effects and the combination of the sprayed chemicals and contaminants. The problem of contamination can be caused.
또한, 중금속, 암모니아등을 화합적 유해물질로 만들지 않는 이온교환방법 및 흡착처리하기 위해서 활성탄이나 제올라이트를 살포하기도 하나 이와 같은 방법은 제올라이트 분말을 사용함으로써 1회 살포로 제올라이트를 재사용할 수 없어 자원의 낭비를 가져올 뿐 아니라 비경제적이었다.In addition, the ion exchange method does not make heavy metals, ammonia, etc. into chemically harmful substances, and the activated carbon or zeolite can be sprayed for adsorption treatment.However, such a method can not reuse the zeolite in one spray by using zeolite powder. Not only was it wasteful, it was uneconomical.
[발명의 목적][Purpose of invention]
본 발명은 상기와 같은 문제점을 해소하기 위해 발명된 것으로, 양어장에서 제올라이트를 충진시킨 다수의 제올라이트컬럼을 설치하고 해당 제올라이트컬럼을 이용하여 양어장 유입수의 암모니움이온을 제거하고 연속적으로 양어장의 물을 유입시켜 암모니움이온을 흡착처리한 처리수로 내보낼 수 있을 뿐만 아니라 스페어 제올라이트컬럼을 이용하여 사용중의 제올라이컬럼 대신 사용할 수 있는 순환식 정수장치를 제공하고자 함에 그 목적이 있다.The present invention has been invented to solve the above problems, install a plurality of zeolite columns filled with zeolite in the fish farm and remove the ammonium ions of the fish farm inlet water using the zeolite column and continuously inflow the water of the fish farm The purpose of the present invention is to provide a circulating water purification device that can be used in place of the zeolite column in use by using a spare zeolite column as well as exporting ammonium ions to the treated water.
[발명의 구성][Configuration of Invention]
상기 목적을 달성하기 위한 본 발명의 양어장에서의 제올라이트컬럼을 이용한 암모니움이온의 제거방법은 천연제올라이트를 염화나트륨으로 전처리하여 제올라이트컬럼(2)에 충전하는 단계, 펌프(PI)로 양어장의 물을 상기 제올라이트(2)에 유입시켜 양어장물의 암모니움이온을 제올라이트에 흡착시키는 단계, 상기 흡착단계에서 암모니움이온이 제거된 처리수(5)가 유출되는 단계로 구성된다.The method for removing ammonium ions using the zeolite column in the fish farm of the present invention for achieving the above object is a step of pre-treating the natural zeolite with sodium chloride to fill the zeolite column (2), the water of the fish farm with a pump (PI) Adsorption into the zeolite (2) comprises the step of adsorbing the ammonium ions of the fish farms to the zeolite, the step of flowing out the treated water (5) from which the ammonium ion is removed in the adsorption step.
다른 제올라이트컬럼(3,4)에서의 암모니움이온 제거단계도 상기 제올라이트컬럼(2)와 동일하게 시행됨으로 상세설명을 생략한다.Ammonium ion removal step in the other zeolite columns (3, 4) is also carried out in the same manner as the zeolite column (2), detailed description thereof will be omitted.
또한, 본 발명의 정수장치는 양어장에서 계속적으로 유입되는 유입수를 1차적으로 여과시키고, 제올라이트컬럼(3,4,5)중 2개를 암모니움이온을 흡착제거하는 사용제올라이트컬럼으로 이용하고 나머지를 스페어제올라이트컬럼으로 이용하여 상기 사용제올라이트컬럼으로 유입수의 암모니움이온을 1차, 2차로 흡착하여 처리수로 배출시키는 것을 순환시키고 한편 배출되는 처리수가 소정 수질기준에 미달될 경우 스페어제올라이트컬럼을 이용하여 상호 제올라이트컬럼을 교환하면서 양어장의 물을 정수시킬 수 있는 정수장치이다.In addition, the water purifying apparatus of the present invention primarily filters the influent continuously introduced from the fish farm, and uses two of the zeolite columns (3, 4, 5) as a zeolite column for adsorption and removal of ammonium ions, and the rest is spared. The zeolite column is used to adsorb the ammonium ions of the inflow water into the zeolite column as primary and secondary, circulating the discharge to the treated water. Meanwhile, when the discharged treated water does not meet a predetermined water quality standard, the zeolite column is mutually used. It is a water purifier that can purify the water of fish farm while exchanging zeolite column.
상기에서, 암모니움이온이 포화흡착되어 스페어상태로 돌아간 제올라이트컬럼은 재생액 탱크(6)의 재생액을 펌프(P2)로 재생배관(A)을 통하여 유입시켜 재생함으로써 다시 재활용되어진다.In the above, the zeolite column in which the ammonium ion is saturated and adsorbed and returned to the spare state is recycled again by introducing the regeneration solution of the regeneration solution tank 6 through the regeneration pipe A to the pump P2 and regenerating it.
상기와 같은 본 발명에 의해서 양어장에서의 유입수중의 암모니움이온(ammonium ion : )으로 포화흡착된 천연제올라이트는 염화나트륨(sodium chloride : NaCl) 또는 염화칼슘(calcium chloride : CaCl2)용액으로 재생하여, 천연제올라이트는 순환하여 암모니움이온을 제거할 수 있어 자원의 재활용화를 기할 수 있다.Ammonium ion in the influent water in the fish farm according to the present invention as described above (ammonium ion: Natural zeolites saturated with) are regenerated with sodium chloride (NaCl) or calcium chloride (CaCl 2 ) solution. .
본 발명의 제올라이트컬럼내의 일정량 제올라이트는 다음과 같은 일반식으로 표시되는 알루미노 규산염으로A certain amount of zeolite in the zeolite column of the present invention is an aluminosilicate represented by the following general formula
여기서 M은 원자가 n인 양이온이고 w는 결정수의 분자수를 나타낸다. x에 대한 y의 비 x/y는 결정구조에 따라 변호하는데 대개 1~5의 값을 가진다.Where M is a cation of atom n and w represents the number of molecules in the crystal water. The ratio of y to x, x / y, depends on the crystal structure and usually has a value from 1 to 5.
이와 같은 제올라이트컬럼내에 충진되는 제올라이트는 그 구조적 특이성 때문에 흡착성, 촉매활성, 이온 교환능이 독특하여 분리, 정제공정등 여러 화학공정에 다양한 용도로 쓰인다.Zeolite filled in such a zeolite column is unique in its adsorption, catalytic activity, and ion exchange ability due to its structural specificity, and thus is used in various chemical processes such as separation and purification processes.
상기와 같은 제올라이트는 특히 양이온교환능이 뛰어나기 때문에 암모니움이온에 대해 대단히 높은 친화력을 가지고 있는 점을 이용하여 천연제올라이트내에 존재하는 양이온이 수원중의 암모니움이온과 교환반응에 의해 흡착제거가 가능한 것이다.Since the zeolite is particularly excellent in cation exchange capacity, it has a very high affinity for ammonium ions, so that cations present in natural zeolites can be removed by adsorption and exchange with ammonium ions in a water source.
상기 제올라이트의 일반식중 양이온인 M은 교환가능한 양이온으로서 칼륨(potassium : K), 나트륨(sodium : Na), 마그네슘(magnesium : Mg) 및 칼슘(calcium : Ca) 등이 있으며 상기중 나트륨이온이 암모니움이온과 교환친화력이 가장 크다.M, which is a cation in the general formula of the zeolite, includes potassium (K), sodium (Na), magnesium (Mg), calcium (calcium), and the like as exchangeable cations. It has the largest exchange affinity with Um ion.
상기와 같이 나트륨이온과 암모니움이온의 교환친화력이 큰 것을 이용하여 본 발명의 정수장체에서의 재생약은 1~2N 염화나트륨용액을 사용하여 암모니움이온을 포화흡착한 제올라이트를 암모니움이온과 나트륨이온을 양이온교환함으로써 재활용할 수 있다.As described above, the regenerant in the purified water body of the present invention using a large exchange affinity between sodium ions and ammonium ions is ammonium ions and sodium ions in the zeolite obtained by saturating and adsorbing ammonium ions using 1 ~ 2N sodium chloride solution. Can be recycled by cation exchange.
따라서, 제올라이트컬럼의 제올라이트는 연속적으로 상기의 양어장의 유입수를 처리할 수 있으며, 큰용량(예컨대 300kl) 제올라이트컬럼에서 아래와 같이 암모니움이온과 이온교환되어 염화암모니움이온으로 된 용액은 드레인으로 빠져나게 폐수처리된다.Therefore, the zeolite of the zeolite column can continuously treat the influent of the fish farm, and in the large-capacity (for example 300kl) zeolite column, it is ion-exchanged with ammonium ions as shown below, so that the solution of ammonium chloride ion escapes to the drain. Wastewater treatment.
이하, 본 발명의 실시예를 예시도면에 의거하여 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
제1도, 제2도 및 제3도는 본 발명의 정수장치가 설치된 양어장에서 스페어제올라이트컬럼을 설정하고 유입수가 사용제올라이트컬럼을 통과하는 동작흐름을 나타낸 것이다.1, 2 and 3 show the operation of setting the spare zeolite column in the fish farm in which the water purification apparatus of the present invention is installed, and the inflow water passes through the zeolite column used.
본 발명의 정수장치는 양어장의 물을 1차적으로 여과시켜 펌프되서 제올라이트컬럼(2,3,4)순으로 유입시키게 되는데, 여기서 2개의 제올라이트컬럼은 사용되는 한편 나머지 제올라이트컬럼은 스페어로서 사용될 수 있다. 상기 제올라이트컬럼(2~4)은 교대로 사용될 수 있다. 상기 제올라이트컬럼(2~4)으로 공급수가 유입되어 유출되는 물의 순환파이프는 50mm 정도의 파이프이고 제올라이트를 재생시키는 재생배관(A) 파이프는 25A 정도이며 컬럼은 예컨대 300kl의 정도의 용량이다.The water purifying apparatus of the present invention is primarily filtered through the water of the fish farm to be pumped into the zeolite column (2, 3, 4) in order, where two zeolite columns are used while the other zeolite column can be used as a spare. The zeolite columns 2 to 4 may be used alternately. The circulation pipe of the water flowing in and out of the feed water into the zeolite columns 2 to 4 is about 50 mm pipe, the regeneration pipe (A) pipe for regenerating the zeolite is about 25 A, and the column has a capacity of about 300 KL, for example.
따라서, 상기 제올라이트컬럼(2~4)은 해당경로의 파이프와 밸브의 개폐를 통해 1차 제올라이트컬럼과 2차 제올라이트컬럼을 거치며 또한 스페어로서 3차 제올라이트컬럼을 설치하여 제올라이트 흡착능력이 저하 되었을 때는 교대로 순환하여 재생하여 사용한다.Therefore, the zeolite columns 2 to 4 pass through the primary zeolite column and the secondary zeolite column by opening and closing pipes and valves of the corresponding path, and alternately when the zeolite adsorption capacity is reduced by installing a tertiary zeolite column as a spare. Recycle and use it.
본 발명의 양어장의 정수장치를 첨부도면에 따라 설명한다.The water purification apparatus of the fish farm of this invention is demonstrated according to attached drawing.
제1도에 있어서는 양어장의 물이 펌프(P1)를 통해 해당 파이프와 개폐의 밸브를 통하여 1차 제올라이트컬럼(2)으로 유입되고 이 제올라이트컬럼(2)에서 양어장의 물을 1차 통과시켜 암모니움이온을 제거시키고, 다시 2차 제올라이트컬럼(3)으로 유입되어 2차 제올라이트처리를 거치며 이렇게 1차, 2차적으로 암모니움이온이 제거된 처리수는 유속기를 통하여 다시 양어장으로 공급되는 물의 순환경로이다.In FIG. 1, the water of the fish farm is introduced into the primary zeolite column 2 through the pipe P and the valve of opening and closing through the pump P1, and the water of the fish farm is first passed through the zeolite column 2 in the ammoniaum.
