도 1은 본 발명에 의해 제조된 순수와 혼합하기 전의 분말 입자의 SEM 사진,1 is a SEM photograph of powder particles before mixing with pure water prepared by the present invention,

도 2는 본 발명에 의해 제조된 순수와 혼합하기 전의 분말 입자의 제타전위측정 그래프이다. 2 is a graph of zeta potential measurement of powder particles before mixing with pure water produced by the present invention.

본 발명은 액상 수처리제에 관한 것으로서, 상세하게는 천연광물을 이용하여 부유물질, 질소, 인 및 악취를 동시에 제거하면서도 2차오염 및 슬러리 부상을 최소화시키는 액상 수처리제의 제조방법에 관한 것이다.The present invention relates to a liquid water treatment agent, and more particularly, to a method for preparing a liquid water treatment agent that minimizes secondary pollution and slurry floating while simultaneously removing suspended solids, nitrogen, phosphorus, and odor using natural minerals.

인구의 증가, 산업발달 및 그로 인한 생활수준의 향상으로 인하여 생활오수, 산업폐수, 가축폐수 등의 각종 폐수의 발생량이 급증하게 되었고, 이러한 폐수는 강물에 흘러들어 강물을 더 이상 각종 용수로 사용할 수 없게 하거나 생물서식에 심각한 피해를 줄 정도로 수질을 오염시킨다.Due to the increase in population, industrial development and the improvement of living standards, the generation of various wastewaters such as living sewage, industrial wastewater, and livestock wastewater has rapidly increased, and such wastewater flows into the river, so that the river can no longer be used for various waters Or pollute the water enough to cause serious damage to biological habitat.

최근에는 소형 마을하수도 정화문제가 사회적인 문제로 대두되고 있다. 마을하수도는 제외지에 여유가 없는 수로형 하천구간으로 대부분의 소하천에서 볼 수 있는 형태로, 오수분리시설이나 차집관로의 제외지 설치가 불가능하며 하수도와 같은 배수로로 이용되기 쉬워 수질오염이 심화되는 문제가 있다.Recently, the problem of small village sewage purification has become a social problem. The village sewerage is a waterway-type river section with no margin for exclusion, which can be found in most small streams. There is.

이러한 수질오염의 원인으로는 가정 및 건물에서 배출하는 생활하수·분뇨, 공장 및 사업장에서 배출하는 산업폐수, 축산시설에서 배출하는 축산폐수·가축분뇨, 강우시 농경지·삼림의 유출수, 야영지·낚시터·유원지 등 수상시설물에서 배출하는 기름·오수·음식찌꺼기·각종 쓰레기, 농가 및 골프장에서 배출하는 농약·비료 등이 있다.The causes of water pollution include household sewage and manure discharged from homes and buildings, industrial wastewater discharged from factories and workplaces, livestock wastewater and livestock manure discharged from livestock facilities, runoff from agricultural land and forests during rainfall, camps, fishing and There are oil, sewage, food waste, various garbage, pesticides and fertilizers from farms and golf courses.

특히 이러한 폐수에 다량 포함된 부유물질, 질소 및 인등 유기물질은 조류의 번식과 성장을 촉진시켜 강이나 호수등의 부영양화를 촉진시키며 악취를 발생시키는 등 생태계 파괴의 주범이다. 한편 이렇게 파괴된 생태계는 그 복구가 거의 불가능하거나 복구에 많은 시간과 비용을 필요로 하므로, 사전에 이러한 오염인자를 제거할 필요성이 대두되었다. In particular, suspended solids, nitrogen and phosphorus organic substances contained in such waste water are the main culprit of destroying the ecosystem by promoting algae reproduction and growth, promoting eutrophication of rivers and lakes, and generating odors. On the other hand, these destroyed ecosystems are almost impossible to recover or require a lot of time and money to recover, so it is necessary to remove these pollutants beforehand.

그러나 현재 오염된 물의 처리를 위해서는 부유물질, 질소, 인 및 악취를 각각 처리하는 시설을 갖추어야 하므로, 설비의 대형화에 따른 건설비, 부지매입비등 투자비와 운전비가 과다하게 소요되는 문제점이 있다. However, in order to treat polluted water at present, it is necessary to have facilities for treating suspended substances, nitrogen, phosphorus, and odor, respectively, and there is a problem in that investment cost and operation cost such as construction cost, site purchase cost, etc. are excessive due to the enlargement of facilities.

또한 종래기술은 화학약품등의 투입으로 인하여 2차 오염을 유발시키며, 하수처리업자는 이러한 2차 오염원을 제거하기 위하여 사후처리가 필요하여 경제적으로도 많은 부담이 되었다. 다량의 슬러지의 발생으로 인하여 처리비용이 과다하게 발생하며, 마이크로 플록(micro floc)의 분리가 필요하다. 또한 미생물을 이용한 방법은 비경제적, 비효율적인 문제점과 외부조건에 영향을 받는 문제점이 있다.In addition, the prior art causes secondary pollution due to the input of chemicals, etc., and the sewage treatment company needs post-treatment in order to remove such secondary pollution sources, which is economically burdensome. Due to the generation of a large amount of sludge, the treatment cost is excessively generated, and the micro floc needs to be separated. In addition, the method using microorganisms has problems that are inefficient and inefficient and influenced by external conditions.

또한 수처리를 위해서는 수처리제를 물에 분산하여야 하는데, 대부분의 수처리제는 분말로서, 오염된 물에 직접 뿌리거나 오염된 물에 뿌리기 전에 분말인 수처리제를 소량의 물에 혼합시켜서 액상으로 만들어서 오염된 물에 분사한다. 그러나 오염된 물에 분말인 수처리제를 직접 뿌리거나, 소량의 물에 혼합하여 액상으로 만들어 오염된 물에 분사하여도 분말 입자들이 뭉쳐서 오염된 물에 고르게 분산되지 않아서 원하는 효과를 얻을 수 없는 문제점이 있었다.In addition, water treatment must be dispersed in water for most treatments. Most water treatments are powders, which are mixed with a small amount of water and sprayed into contaminated water before being sprayed directly onto contaminated or contaminated water. do. However, even if sprayed with a water treatment agent as a powder directly on the contaminated water, or mixed with a small amount of water to make a liquid and sprayed into the contaminated water, the powder particles are not evenly dispersed in the contaminated water, there is a problem that can not achieve the desired effect .

본 발명은 상기된 문제점을 해결하기 위하여 안출된 것으로서, 부유물질, 질소, 인 및 악취를 동시에 제거하여 수처리효과를 상승시키면서도, 2차오염 및 슬러지 부상량을 최소화시킬 수 있는 액상 수처리제의 제조방법을 제공함에 그 목적이 있다.The present invention has been made in order to solve the above problems, while simultaneously removing a floating material, nitrogen, phosphorus and odor to increase the water treatment effect, while the second method of producing a water treatment agent to minimize the pollution and sludge flotation. The purpose is to provide.

본 발명에 의한 부유물질, 질소, 인 및 악취제거용 액상 수처리제의 제조방법은 맥황토 17-23wt%, 방해석 9-11wt%, 폐각 9-11wt%, 석회석 9-11wt%, 장석질여과사 17-23wt%, 제올라이트 9-11wt%, 게르마늄 6-8wt%, 갈염석 6-8wt%, 화운석5-7wt%를 파쇄 및 밀링하여 미세한 분말을 얻는 단계; 상기 분말에 전체 분말대비 0.1~5wt%의 K2SiF6와 전체 분말대비 10~15wt%의 CaCl2와 BaCl2를 순차적으로 투입하는 단계; 가열로에서 600℃에서 5시간 소성하는 단계; 소성된 분말을 구연산으로 60℃에서 2시간 산처리하는 단계; 산처리된 분말을 미세한 분말로 밀링하는 단계; 밀링된 분말을 사이클론을 이용하여 10㎛이하의 분말만 선별하는 단계; 선별된 분말을 순수에 넣어 고속회전시켜서 교반하는 단계를 포함하는 것을 특징으로 한다.The preparation method of the liquid water treatment agent for removing suspended solids, nitrogen, phosphorus and odor according to the present invention is 17-23wt% wort clay, 9-11wt% calcite, 9-11wt% waste, 9-11wt% limestone, feldspar filter 17 Crushing and milling -23 wt%, 9-11 wt% zeolite, 6-8 wt% germanium, 6-8 wt% brown salt, 5-7 wt% calcite, to obtain a fine powder; Sequentially adding 0.1-5 wt% K 2 SiF 6 and 10-15 wt% CaCl 2 and BaCl 2 relative to the total powder to the powder; Firing at 600 ° C. for 5 hours in a heating furnace; Acid-treated the calcined powder at 60 ° C. for 2 hours with citric acid; Milling the acid treated powder into fine powder; Selecting only the powder of 10 탆 or less using the cyclone with the milled powder; The selected powder is characterized in that it comprises the step of stirring by rotating at high speed in pure water.

본 발명에 의한 액상 수처리제의 제조방법에 대하여 자세히 설명하면 아래와 같다.Hereinafter, the method for preparing the liquid water treatment agent according to the present invention will be described in detail.

먼저 맥황토, 방해석, 폐각, 석회석, 장석질여과사, 제올라이트, 게르마늄, 갈염석, 화운석를 파쇄 및 밀링하여 미세한 분말을 얻는다. 이 과정에서는 광석을 채취하여 파쇄하고, 파쇄된 광물을 지르코늄 볼 밀(ball mill)을 이용하여 수백 nm 내지 수십 ㎛로 밀링한다. First, pulsar, calcite, waste shell, limestone, feldspar filter, zeolite, germanium, brown salt and calcite are crushed and milled to obtain fine powder. In this process, the ore is collected and crushed, and the crushed mineral is milled to a few hundred nm to several tens of micrometers using a zirconium ball mill.

각각의 광물들의 혼합비율은 경제성, 원자재 수급 문제, 부유물질 질소 인 악취의 동시제거효과 및 수많은 실험 결과에 따른 수처리 효과등을 고려할 때, 맥황토 17-23wt%, 방해석 9-11wt%, 폐각 9-11wt%, 석회석 9-11wt%, 장석질여과사 17-23wt%, 제올라이트 9-11wt%, 게르마늄 6-8wt%, 갈염석 6-8wt%, 화운석5-7wt%인 경우가 가장 바람직하다. 맥반석이 23wt% 초과되면, 점도가 높아져서 수중에서 분산이 제대로 되지 않는 효과가 있으며, 17wt% 미만이면, 응집이 제대로 되지 않는 문제점이 있으며, 폐각 및 석회석은 pH 조정용으로 과량이 들어가면 pH가 지나치게 높아지고, 소량이 들어가면 pH가 지나치게 낮아지는 문제가 있으며, 포타슘 방해석 제올라이트 게르마늄 갈염석 화운석은 소량이 들어가면 부유물질 질소 인 악취에 제거효과가 없으며, 과량으로 들어가면 부유물질 질소 인 악취중에서 일부만 제거되는 문제점이 있다. 이렇게 밀링된 미세한 광물에는 SiO2 , CaCo3, Ca(OH)2, Al2O3, MgO, Fe2O3 , TiO2등이 포함되어 있다.The mixing ratio of each mineral is 17-23wt% maltite, 9-11wt%, pulverized 9, considering economical efficiency, raw material supply and demand, simultaneous removal of suspended nitrogen, phosphorous odor, and water treatment effect according to numerous experiments. Most preferred is -11wt%, limestone 9-11wt%, feldspar filter 17-23wt%, zeolite 9-11wt%, germanium 6-8wt%, brown salt stone 6-8wt%, pyranite 5-7wt% . If the gannite is more than 23wt%, the viscosity is high, there is an effect that the dispersion is not properly in water, if less than 17wt%, there is a problem that the aggregation is not properly, the waste shell and limestone is too high pH when the excess amount for pH adjustment, If a small amount enters, there is a problem that the pH is too low, and potassium calcite zeolite germanium gallbladder calcite does not have a removal effect on the odor of suspended solids nitrogen when entered in a small amount; . The milled fine minerals include SiO 2 , CaCo 3 , Ca (OH) 2 , Al 2 O 3 , MgO, Fe 2 O 3 , TiO 2 , and the like.

다음으로 상기 분말에 K2SiF6와 CaCl2, BaCl2를 순차적으로 투입한다. 일반적으로 제재의 비표면적을 극대화하기 위한 소성온도는 1,200℃이상이 되어야 하는데, 이러한 노는 흔하지 않으며, 비용이나 에너지 측면에서 불리한 점이 많다. K2SiF6는 이러한 문제점을 극복하기 위하여 낮은 온도에서 소성하기 위해 융제로서 투여하는 것인데, 이는 전체 분말 중량 대비 0.1-5%로 투여하는 것이 바람직하다. 0.1% 미만이면 융제로서의 효과가 없으며, 5%를 초과하면 경제성이 없기 때문이다. 또한 분말이 수중에서 원활하게 분산시키기 위하여 CaCl2, BaCl2를 전체 분말 중량 대비 10-15%로 주입하게 되는데, 이는 분말 입자들간의 반발력을 극대화시켜서 분말 입자들이 액상에서 서로 뭉치는 것을 방지하게 된다. 10%이하로 첨가하면 입자간 응집(coagulation)이 일어나 침강되며, 15%초과하면 비용 대비 효과 증가가 미비하다.Next, K 2 SiF 6 , CaCl 2 and BaCl 2 are sequentially added to the powder. In general, the firing temperature for maximizing the specific surface area of the lumber should be 1,200 ° C. or more. Such furnaces are not common and have disadvantages in terms of cost and energy. To overcome this problem, K 2 SiF 6 is administered as a flux to be fired at a low temperature, which is preferably administered at 0.1-5% of the total powder weight. If it is less than 0.1%, there is no effect as a flux, and if it exceeds 5%, it is economical. In addition, CaCl 2 and BaCl 2 are injected at 10-15% of the total powder weight in order to disperse the powder smoothly in water. . If it is added below 10%, coagulation occurs between particles and settles, and if it exceeds 15%, the effect of cost increase is insignificant.

다음으로 가열로에서 600℃로 5시간 소성을 하게 되며, 소성 후에는 구연산(C6H8O7)으로 60℃에서 2시간 산처리한 후에 이를 증류수로 세척을 한 후 건조시키게 됩니다. 소성을 통하여 입자의 비표면적이 극대화되며, 융제를 투입함으로 인하여 소성온도가 낮추어질 수 있는데, 최소한 600℃로 5시간 소성하여도 원하는 목적을 달성할 수 있게 된다. 산처리를 하는 목적은 소성 후 거칠어져 있는 입자의 표면을 매끄럽게 하여 입자간 물리화학적 특성이 저하되는 것을 막기 위함이며, 아울러 일부 공정진행과정에서 유입될 수 있는 유기물을 제거하기 위함이다. 이는 구 연산과 같은 통상적인 약산을 이용하는 것이 유리하며, 실험결과 60℃에서 2시간 산처리하는 것이 물과 교반 후 전기전도도상에서 최적의 효율을 나타낸다. Next, it is calcined at 600 ° C. for 5 hours in a heating furnace. After firing, the acid is treated with citric acid (C 6 H 8 O 7 ) at 60 ° C. for 2 hours and then washed with distilled water and dried. Through firing, the specific surface area of the particles is maximized, and the firing temperature can be lowered by adding a flux. Even if the firing is carried out at least 600 ° C. for 5 hours, the desired purpose can be achieved. The purpose of the acid treatment is to smooth the surface of the roughened particles after firing to prevent degradation of the inter-particle physicochemical properties, and to remove organic substances that may be introduced during some processes. It is advantageous to use a conventional weak acid such as a sphere operation, and the experimental results show that the acid treatment at 60 ℃ for 2 hours shows the optimum efficiency on the electrical conductivity after stirring with water.

건조된 분말은 다시 에어 제트 밀링(air jet milling)등의 방법으로 10㎛이하의 미세한 분말로 밀링을 한다. 소성가공을 통하여 입자의 비표면적이 극대화되어서 우수한 흡착능을 갖게 되며, 아울러 에어제트 밀링을 통하여 분말은 10㎛ 이하의 작은 입자가 되어서 수중 접촉면적이 극대화된다. 도 1는 이렇게 분쇄된 분말의 SEM 사진인데, 사진에서 보는 바와 같이 분말은 6각 구조의 형태이며, 각각이 음전하를 띠고 있어 끌어당기는 힘이 강해 슬러지의 안전화 및 부상억제효과가 있다.The dried powder is again milled into fine powder of 10 μm or less by air jet milling or the like. Through plastic processing, the specific surface area of the particles is maximized to have excellent adsorption capacity, and through air jet milling, the powder becomes small particles of 10 μm or less, thereby maximizing the contact area in water. Figure 1 is a SEM picture of the powder so pulverized, as shown in the photograph is a powder in the form of a hexagonal structure, each has a negative charge has a strong pulling force has the effect of safety and flotation suppression of sludge.

밀링된 분말을 사이크론을 이용하여 10㎛이하의 입자만을 선별한다. 제제의 분산안정성 확보를 위한 최적의 입도(이론치)는 0.12㎛이상이지만 실험결과 수㎛에서 10㎛이하정도에서도 분산 안정성이 확보되었다. 따라서 10㎛이하의 입자만 액상 수처리제를 만드는데 이용하고, 10㎛이상의 입자는 피드백되어 재분쇄시킨다. The milled powder is selected using only the particles of 10 μm or less using cyclone. The optimum particle size (theoretical value) for securing the dispersion stability of the formulation is 0.12 ㎛ or more, but the experimental results showed that the dispersion stability was secured even from several μm to 10 μm or less. Therefore, only particles of 10 μm or less are used to make the liquid water treatment agent, and particles of 10 μm or more are fed back and regrind.

마지막으로 밀링된 미세한 분말을 순수(deionized water)에 넣고 300RPM이상이 속도로 고속 교반하여서 액상 수처리제를 얻는다. 순수의 양은 밀링된 미세한 분말이 충분히 용해될 수 있는 정도이며, 오폐수의 오염정도에 따라서 그 농도가 조정될 수 있다. 일반적으로 순수 1톤에 분말이 약 10KG정도 넣는 것이 가장 바람직하다.Finally, the milled fine powder is placed in deionized water and stirred at a high speed of at least 300 RPM to obtain a liquid water treatment agent. The amount of pure water is such that the milled fine powder can be sufficiently dissolved, and its concentration can be adjusted according to the degree of contamination of the waste water. In general, it is most preferable to put about 10KG of powder in 1 ton of pure water.

이러한 본 발명에 의한 액상 수처리제의 수처리 작용에 대하여 설명하면, 본 발명에 의할 경우 질소의 제거는 암모니아 탈기법을 이용하는데, 암모니아 탈기법은 NH4 +이온과 NH3의 평형방정식(화학식 1)에서 pH가 7이상으로 증가하면 평형은 왼쪽으로 이동하여 NH4 +이온이 NH3로 변하며, 이때 폐수를 저어주어 대기중으로 탈기시켜 제거하는 방법으로 폐수의 pH를 올리는데 석회석 및 폐각이 그 역할을 한다.When explaining the water treatment action of the liquid water treatment agent according to the present invention, the removal of nitrogen in the present invention uses ammonia degassing method, the ammonia degassing method is the equilibrium equation of NH 4 + ion and NH 3 (Formula 1) When pH rises above 7, the equilibrium shifts to the left, and NH 4 + ions change to NH 3, where limestone and waste angle play a role in raising the pH of the wastewater by removing the wastewater by degassing it into the atmosphere. .

NH3 + H2O ＜＝＞ NH4 ++ OH- NH 3 + H 2 O <=> NH 4 + + OH -

또한 본 발명에 의한 액상 수처리제에 포함되어 있는 풍부한 알루미늄성분, 철, 칼슘 및 마그네슘의 성분이 알루미늄염(Al3 +), 철염(Fe3 +), 칼슘염(Ca2 +), 마그네슘염(Mg2+)으로 이온화된다. 이러한 금속이온에 의해 인산염이 Al(PO4), Fe(PO4), Ca3(PO4)2의 형태로 침전 제거되고 유기물 입자형태로 되어있는 유기성인도 응집 가능하며, 각 응집제의 반응식은 다음과 같다.In addition, abundant aluminum components, iron, calcium and magnesium components contained in the liquid water treatment agent according to the present invention are aluminum salt (Al 3 + ), iron salt (Fe 3 + ), calcium salt (Ca 2 + ), magnesium salt (Mg 2+ ). These metal ions allow the phosphate to precipitate out in the form of Al (PO 4 ), Fe (PO 4 ), Ca 3 (PO 4 ) 2 , and to aggregate organic phosphorus in the form of organic particles. Same as

Al3 +++ PO4 3 - → Al(PO4) Al 3 + ++ PO 4 3 - → Al (PO 4)

Fe3 ++PO4 3 -→ Fe(PO4) Fe 3 + + PO 4 3 - → Fe (PO 4)

3Ca2 ++ 2PO4 3 - → Ca3(PO4)2 3Ca 2 + + 2PO 4 3 - → Ca 3 (PO 4) 2

한편 응집 반응은 물리적 이동과 화학적 흡착이라고 하는 이 두 개 연속의 동력학적 과정을 통해서 일어난다. 물리적 이동은 하나의 어떤 콜로이드 입자의 표면을 다른 콜로이드 입자의 표면에 이동시키는 것으로서, 브라운 운동, 용액의 전단력, 중력 등에 의하여 일어난다.Coagulation reactions, on the other hand, occur through two successive kinetic processes called physical transport and chemisorption. Physical movement is the movement of the surface of one colloidal particle to the surface of another colloidal particle, which is caused by Brownian motion, shear force of the solution, gravity, and the like.

두 개의 입자간에 작용하는 힘은 입자간의 거리와 반비례적인 함수관계가 있고, 물리적인 이동에 의하여 형성되는 새로운 힘의 평형에 의하여 두 개의 입자가 응결하는 화학적인 흡착 반응이 발생한다. The force acting between the two particles is inversely related to the distance between the particles, and the chemical adsorption reaction occurs in which the two particles condense due to the equilibrium of new forces formed by physical movement.

이러한 물리적인 이동과 화학적인 흡착반응이 수중에서 일어나기 때문에 분말의 입자에 콜로이드성 부유물질, 부영양화물질 및 조류 등의 응집 반응을 하게 된다.  Since the physical movement and chemical adsorption reactions occur in water, the particles of the powder undergo coagulation reactions of colloidal suspended solids, eutrophic substances, and algae.

본 발명에 의한 수처리분말은 천연재제의 분쇄·소성를 통하여 마이크로 포어(Micro Pore)를 갖고 콜로이드성 부유물질을 흡착 제거한다.The water treatment powder according to the present invention has a micro pore through pulverization and firing of natural materials and adsorbs and removes colloidal suspended solids.

한편 본 발명에 의한 액상 수처리제에는 TiO2가 일부 포함되어 있는데, 이러한 TiO2는 광촉매로서 햇빛, 형광등의 조사에 의해서 강력한 탈취 성능을 나타내어, 암모니아, 포름알데히드, 황화수소등의 악취의 원인물질을 제거한다.On the other hand there is a liquid water treatment agent according to the present invention, the TiO 2 comprises a part, such TiO 2 is As a photocatalyst, it shows strong deodorization performance by irradiation of sunlight, fluorescent lamps, and removes the causative agents of odors such as ammonia, formaldehyde, hydrogen sulfide.

본 발명에 의한 액상 수처리제는 기존의 천연제올라이트와 비교하여 SiO2 함량을 낮추어 염기치환용량을 낮추었고, 폐각등을 첨가하여서 알카리파위를 높인 결과 입자표면의 총전하가 0 이 되는 영전하점이 약 pH 2로 넓은 pH영역대에서 양이온 교환능이 우수하다.(도 2 참조) The liquid water treatment agent according to the present invention lowers the base substitution capacity by lowering the content of SiO2 compared to the existing natural zeolite, and increases the alkali wave by adding waste shells. Excellent cation exchange capacity in a wide pH range (see Figure 2).
