Reaction to clay minerals of allophane, an amorphous aluminum silicate, or imogolite, an aluminum salt of semi-crystalline silicate Marine minerals and plants with high Fulvic acid content in the form of Clay minerals, or stabilization with zeolite by heating the coal ash or incineration ash in 90 ° C to 180 ° C in primary alkali aqueous solution. And peat produced by the deposition of diatoms Chelated fulvic acid was mixed with inorganic / organic weight ratio in the ratio of 1 ~ 1.25 and heated at 90 ~ 100 ℃ to inject acid and stirred for at least 4 hours while adjusting pH to 2.0 ~ 2.5. Humic soil containing a large amount of mineral complex salt was made, and then cooled to room temperature, and then supplied with hydrogen equivalent peroxide (H 2 O 2 ) and ferrous sulfate (FeSO 4 ) in equivalent weight equivalents.

석탄회나 소각회에서 알로페인질 점토광물을 만드는 방법으로 대한민국특허공개번호 2001-0089935호 에서는 석탄회나 소각회를 알칼리처리를 하지 않고 바로 산처리를 하여 알로페인질을 만들므로서 생산비는 저렴하지만 아로페인질로 전환율이떨어지므로서 이온교환능력이 떨어지는 점이 있다.As a method of making allopine clay clay mineral from coal ash or incineration ash, Korean Patent Publication No. 2001-0089935 discloses that the coal ash or incineration ash is treated with acid without alkali treatment to produce allophosphine so that the production cost is low. As the conversion rate decreases due to the paint quality, the ion exchange capacity is inferior.
분뇨나 축산폐수와 같이 유기물과 질소, 인과 같은 오염물질의 농도가 높은 폐수에 시리카(Siliga)를 함유한 첨가제를 사용한 일본특허공개번호 2001 -179284호와 평(平)11-033590호의 경우 단순응집 또는 첨가제의 목적으로 유입폐수에 주입하여 처리를 하였으나 처리효율을 크게 향상하지는 못하였다.In the case of Japanese Patent Publication Nos. 2001 -179284 and Pyeong 11-033590, which use additives containing silica in wastewater with high concentrations of organic substances, such as manure and livestock waste, and nitrogen, phosphorus, etc., simple aggregation Or it was injected into the influent wastewater for the purpose of additives, but it did not significantly improve the treatment efficiency.
그리고, 시리카 성분을 함유한 부석(Pumice)과 부식물질을 주체로 하는 토양성형체를 이용한 일본특허공개번호 평(平)10-034175호와 평(平)07-100470호의 경우에는 폐수중 유기오염물질과 질소, 인과 같은 영양물질을 부식화반응에 의해서 처리를 하였으나 부식화반응의 경우 질소화합물은 배출되는 부식전구물질에 부동화(Immobilization)되어 잉여오니로 배출하여 제거되는데, 기체상태의 질소(N2)가스(Gas)로 탈질처리되는 것으로 보았으며, 부식화반응이 원활하게 일어나기 위해서는 산화환원전위(ORP) 값을 적절히(+250∼+350mV) 조절하여야 하는데 산화환원전위값의 조정을 전혀 고려하지 않는등 처리 메커니쥼(Mechanisms)을 잘못 파악한 처리공정으로서 처리효율을 크게 향상할 수 없었다.In the case of Japanese Patent Publication Nos. Hei 10-034175 and Hei 07-100470 using soil moldings containing mainly silica and corrosive substances, the organic pollutants in the wastewater. and nitrogen, for although the processing corrosion reaction by corrode such as phosphorus nutrients reaction are removed by the immobilized (immobilization) corrosion precursors that are nitrogen compound emissions discharged into the excess sludge, a nitrogen in the gas phase (N 2 It was considered that the denitrification was carried out by gas, and in order for the corrosion reaction to occur smoothly, the redox potential (ORP) should be adjusted appropriately (+250 to + 350mV), but no adjustment of the redox potential was considered. As a treatment process that misidentifies treatment mechanisms, such treatment efficiency could not be greatly improved.
적조, 녹조처리 방법으로서는 황토를 이용하는 방법으로 대한민국특허 공개번호 1998-033476호, 1999-083053호 및 1999-085575호가 있으며, 이외에도 전기적인 방법, 길항미생물을 이용하는 방법, 불포화지방산을 살포하는 방법, 세라믹제를 살포하는 방법등 다양한 방법이 제시되어 있으나 경제적이면서 효율적으로 처리할 수 있는 방법은 없는 실정이다.The red tide and the green algae treatment methods include the use of yellow soil, and Korean Patent Publication Nos. 1998-033476, 1999-083053, and 1999-085575. In addition, electrical methods, methods using antagonists, methods of spraying unsaturated fatty acids, and ceramics Various methods such as spraying the agent have been proposed, but there is no economical and efficient method.
본 발명은 상기와 같은 문제점을 해소하기 위해 양이온치환용량(Cation exchange capacity ; CEC)과 음이온치환용량(Anion exchange capacity ; AEC)이 높은 정화제를 하·폐수처리, 분뇨처리나 녹조, 적조 발생지역에 살포하여 유기산,질소, 인, 중금속과 같은 이온성물질을 흡착결합하여 물에 불용성인 고형물질로 전환하여 처리를 하므로써 경제적이면서 효율적으로 처리하는 방법을 제공하는데 본 발명의 목적이 있는 것이다.In order to solve the above problems, the present invention has a high cation exchange capacity (CEC) and anion exchange capacity (AEC) purifying agent in sewage, wastewater treatment, manure treatment or green algae, red tide generation area. An object of the present invention is to provide a method for economically and efficiently treating by sorbing ionic substances such as organic acids, nitrogen, phosphorus, heavy metals and converting them into solid materials that are insoluble in water.
이와 같은 목적을 달성하기 위해 본 발명은, 소각로에서 배출되는 소각회나 화력발전소에서 배출되는 석탄회를 1차 알칼리 처리를 하여 제올라이트로 전환후 산처리를 하여 높은 양이온치환용량과 음이온치환용량을 가지는 알로페인이나 이모고라이트 점토광물을 만들거나, 1차 알칼리 처리를 한 석탄회나 소각회에 이탄을 혼합하여 산처리를 한후 과산화수소와 황산제일철을 주입하여 킬레이트성 과산화풀브산미네랄착염과 산화효소와 같은 활성물질이 다량 함유된 활성부식물질을 만들어 하·폐수처리, 분뇨처리에 살포하면 조류번식에 영양물질인 질소, 인과 유기산, 중금속과 같은 이온성물질을 흡착 결합하여 물에 불용성물질로 전환하므로서 경제적이면서 효율적으로 처리할 수 있는 특징이 있다.In order to achieve the above object, the present invention, incineration ash discharged from the incinerator or coal ash discharged from the thermal power plant is subjected to primary alkali treatment to convert to zeolite and acid treatment to have a high cation substitution capacity and anion substitution capacity Active materials such as chelating peroxide, mineral complex salts and oxidases are made by making peat or imogite clay minerals, or by mixing peat with primary alkali-treated coal ash or incineration ash, followed by acid treatment. When this active corrosive material is made and sprayed on sewage / wastewater treatment and manure treatment, it is economically and efficiently by adsorbing and combining nutrients such as nitrogen, phosphorus, organic acids and heavy metals which are nutrients for algae breeding and converting them into insoluble materials in water.

도 1은 정화제 제조 공정도1 is a manufacturing process chart
본 발명에서 원료로 사용하는 석탄회나 소각회는 석탄이나 산업폐기물의 연소시 불연성 회(灰)성분이 연소온도가 광물질의 융점(1400∼1450℃) 이상인 1500∼1700℃로 연소될 때 물엿과 같은 상태로 용융되었다가 냉각되면서 구상의 비정질무수규산알루미늄으로 된다.Coal ash or incineration ash used as a raw material in the present invention is the same as starch syrup when the non-combustible ash component is burned at 1500-1700 ° C. when the combustion temperature is higher than the melting point (1400-1450 ° C.) of the mineral when burning coal or industrial waste. It melts in a state and then cools to form spherical amorphous aluminum anhydrous silicate.
석탄회의 성분은 연료 석탄의 종류에 따라서 약간의 차이가 있으나 대개 SiO2와 Al2O3가 70∼80％ 정도 존재하며, 이외의 성분으로는 Fe2O3, CaO, MgO, TiO2,Na2O, K2O 등이 소량 함유되어 있는 점토토양의 조성과 유사하다.Coal ash is slightly different depending on the type of fuel coal, but SiO 2 and Al 2 O 3 are usually present in 70 to 80%. Other components are Fe 2 O 3 , CaO, MgO, TiO 2 , Na It is similar to the composition of clay soil containing small amounts of 2 O and K 2 O.
그러나, 회가 점토토양과 다른점은 점토토양은 결정질의 규산알루미늄염의 광물인데, 석탄회나 소각회는 연소시 에너지를 받아 용융되었다가 냉각되면서 비정질무수규산알루미늄이 되면서 대부분 미네랄 성분이 활성화되어 있다.However, unlike clay ash clay, clay soil is a mineral of crystalline aluminum silicate salt. Coal ash or incineration ash is energized by combustion and is melted and cooled to become amorphous aluminum silicate. Most minerals are activated.
이중 알칼리금속 및 알칼리토금속의 일부는 유리 산화물의 형태로 존재하기 때문에 수용액에서 가수분해되면 알칼리성이 된다.Some of the alkali metals and alkaline earth metals exist in the form of free oxides, and therefore become alkaline when hydrolyzed in aqueous solution.
석탄회 또는 소각회에 가성소다(NaOH), 탄산소다(Na2CO3), 소석회(Ca(OH)2) 등의 4∼8N 정도의 알칼리수용액을 가하고 90∼180℃로 가열하면서 8∼24시간 정도 교반반응을 하여 제올라이트로 전화시킨다.8 to 24 hours while adding alkaline aqueous solution such as caustic soda (NaOH), sodium carbonate (Na 2 CO 3 ), calcined lime (Ca (OH) 2 ), etc. The reaction is stirred to a degree and converted to zeolite.
제올라이트로 전환하는 반응이 완료되면 탈수후 수세를 한 다음 황산(H2SO4), 염산(HCl)과 같은 산성의 수용액을 가해서 pH를 3.5∼6.5로 조정하고 90∼100℃로 가열하면서 4시간이상 교반반응을 하면 비정질화수규산알루미늄염의 형태인 알로페인[(1∼2)SiO2·Al2O3·(2.5∼3)H2O]이나 준정질화수규산알루미늄염의형태인 이모고라이트[(OH)3·Al2O3·SiOH]로 전환된다.After completion of the conversion to zeolite, washed with water after dehydration, acidic aqueous solution such as sulfuric acid (H 2 SO 4 ), hydrochloric acid (HCl) was added to adjust the pH to 3.5-6.5 and heated to 90-100 ℃ for 4 hours. In the above stirring reaction, allophane [(1 ~ 2) SiO 2 · Al 2 O 3 · (2.5 ~ 3) H 2 O] in the form of amorphous aluminum silicate salt or imogolite [in the form of quasi-crystalline aluminum silicate salt] (OH) 3 Al 2 O 3 SiOH].
석탄회와 같이 규반비(SiO2/ Al2O3중량비)가 2∼3인 경우 pH를 5.0∼6.0의 약산성에서 90∼100℃로 가열하면서 4시간이상 교반반응을 하면 주로 알로페인질이 생산되며, 소각회와 같이 규반비가 1.0 정도로 낮은 경우 pH를 3.5∼4.5를 조정하고 90∼100℃로 가열하면서 4시간이상 교반반응을 하면 주로 이모고라이트가 생산된다.When the silicide ratio (SiO 2 / Al 2 O 3 weight ratio) is 2 to 3, such as coal ash, when all the agitation reaction is heated for 4 hours or more at a pH of 5.0 to 6.0 at 90 to 100 ° C., allophosphine is mainly produced. For example, incineration ash, when the silo ratio is as low as 1.0, adjust the pH to 3.5 to 4.5 and stir for more than 4 hours while heating to 90 to 100 ℃, mainly imogolite is produced.
제올라이트는 암모늄이온(NH4 +), 금속이온과 같은 양이온만 치환하는 능력이 있는데 반해서 알로페인과 이모고라이트는 암모늄이온(NH4 +), 중금속이온과 같은 양이온치환능력과 유기산, 인산과 같은 음이온치환능력을 동시에 가지고 있기 때문에 축산폐수나 분뇨와 같이 유기물, 질소, 인농도가 높은 폐수의 생물학처리 공정에 살포하면 유기산, 질소, 인, 중금속등은 흡착결합을 하여 물에 불용성물질인 고형물로 전환하기 때문에 처리효율을 향상할 수 있다.Zeolites have the ability to substitute only cations such as ammonium ions (NH 4 + ) and metal ions, while allophane and imogolite have cation substitution capabilities such as ammonium ions (NH 4 + ) and heavy metal ions, and organic acids and phosphoric acid. Since it has anion exchange capacity at the same time, when it is applied to biological treatment process of organic matter, nitrogen, phosphorus wastewater such as livestock wastewater or manure, organic acid, nitrogen, phosphorus, heavy metals, etc. are adsorbed and combined into solids that are insoluble in water. By switching, the processing efficiency can be improved.
또한, 녹조와 적조가 발생한 장소에 알로페인이나 이모고라이트를 살포하면 조류의 영양소인 질소, 인과 조류자체를 흡착결합을 하여 물에 불용성의 고형물로되어 침전되므로서 조류의 번식이 억제하게 된다.In addition, when allophane or imogolite is sprayed at the place where green algae and red tide occur, the algae nutrients, nitrogen, phosphorus and algae themselves are adsorbed and precipitated as water insoluble solids, thereby inhibiting the growth of algae.
그리고, 석탄회나 소각회를 ④의 반응에서와 같이 알칼리 고온처리를 하여 제올라이트로 전환후 수세한 것에 이탄을 무기물/유기물의 무게비가 1.0∼1.25의 비율로 혼합하고 산을 가해서 pH를 2.0∼2.5로 조정하여 90∼100℃로 가열하면서 4시간이상 교반반응을 하면 이탄중 킬레이트성 풀브산이 유리되며, 제올라이트는 알로페인 및 이모고라이트로 전환되면서 풀브산과 반응하여 킬레이트성 풀브산미네랄착염 형태의 부식토가 생성된다.Then, coal ash or incineration ash was subjected to alkali high temperature treatment, converted into zeolite and washed with water, and the mixture was washed with peat at an inorganic / organic weight ratio of 1.0 to 1.25 and acid was added to pH 2.0 to 2.5. When the mixture is heated to 90 to 100 ° C. and stirred for at least 4 hours, the chelate fulvic acid is liberated in peat, and the zeolite is converted to allophane and imogolite and reacts with fulvic acid to form a chelate fulcate mineral complex salt. Is generated.
상온으로 냉각한 다음 킬레이트성 풀브산미네랄착염에 과산화수소(H2O2)와 황산제일철(FeSO4)을 가해 산화환원전위(ORP) 값이 +300∼+400mV로 조정하면서 교반반응을 한다음 2개월 이상 숙성을 하면 킬레이트성 과산화풀브산착염, 산화효소와 기타활성물질이 다량 함유된 활성부식물질이 생성된다.After cooling to room temperature, hydrogen peroxide (H 2 O 2 ) and ferrous sulfate (FeSO 4 ) were added to chelating fulbrate mineral complex salts, followed by stirring while adjusting the redox potential to +300 to +400 mV. Aging for more than a month results in the formation of active corrosive substances containing large amounts of chelating peroxide complexes, oxidases and other active substances.
전술한 활성부식물질은 양이온치환능력과 음이온치환능력을 함께 가지고 있으면서, 토양미생물에 미네랄공급을 원활하게 하므로써 토양의 부식화미생물 및 이들 미생물과 상호공생관계에 있는 토양미생물의 생육을 활발하게 하며, 자체산화기능, 산화탈취의 촉매기능, 유기물질을 물에 불용성이면서 비휘발성의 부식물질로 전환하는 부식화반응을 촉진하는 촉매기능 등을 가지고 있다.The above-mentioned active corrosive substance has both cation substitution ability and anion substitution ability, and facilitates the growth of corrosive microorganisms of soil and soil microorganisms which are mutually symbiotic with these microorganisms by facilitating mineral supply to soil microorganisms. It has a self-oxidation function, a catalytic function of oxidative deodorization, and a catalytic function to promote the corrosion reaction of converting organic materials into water insoluble and nonvolatile corrosive materials.
따라서, 활성부식물질을 하·폐수처리, 분뇨처리의 생물학처리공정에 0.00006∼0.06％ 정도 공급하면 BOD, COD, 질소, 인과 같은 오염물질의 제거효율을 향상하면서 시스템(System) 전체에서 악취발생을 저감할 수 있다.Therefore, the supply of active corrosive material to the biological treatment process of sewage, wastewater treatment and manure treatment provides 0.00006 ~ 0.06% to improve the efficiency of removing contaminants such as BOD, COD, nitrogen, phosphorus, etc. Can be reduced.
녹조, 적조발생 지역에도 활성부식토를 살포하면 조류의 영양소가 되는 질소, 인 및 조류자체를 흡착결합하여 고착화하여 침전되면서, 조류와 상호길항(Antagonism) 및 경합(Competition) 관계에 있는 부식화미생물 및 이들 미생물과 상호공생관계에 있는 토양미생물이 우점적으로 생육하는 환경분위기로 되므로써 녹조, 적조의 발생을 예방 또는 처리를 할 수 있게 된다.When spraying active corrosive soils on green algae and red tide areas, they adsorb and bind to nitrogen, phosphorus, and algae, which are nutrients of algae, and settle, causing corrosive microorganisms that have an interantagonism and competition relationship with algae. Soil microorganisms which are mutually symbiotic with these microorganisms become the environmental environment that grows predominantly, thereby preventing or treating the occurrence of green algae and red tide.

슬러지(Slurry) 돈사에서 배출되는 축산폐수 15㎥/일을 2단 활성오니로 처리하는 공정에 석탄회를 알로페인질로 전환한 것을 5000ppm 정도 주입하면서 운전한결과와 활성부식토를 50ppm 주입하면서 운전한 결과는 표 1의 내용과 같다.In the process of treating livestock wastewater 15sl / day discharged from sludge pigs with two stages of activated sludge, it was operated while injecting about 5000ppm of coal ash into allophyllin and 50ppm of activated corrosion soil. It is the same as the content of Table 1.
[실시 예2]Example 2
녹조가 발생한 저수지에 석탄회에서 제조한 알로페인과 이모고라이트를 200ppm 정도로 격일로 5회 살포한 결과 15일 이후 녹조는 처리되었다.Green algae and imogolite, which were produced from coal ash, were sprayed five times every other day on the basis of 200 ppm, and green algae were treated after 15 days.
[실시 예3]Example 3
녹조가 발생한 저수지에 알로페인 및 이모고라이트 50∼60ppm과 활성부식토 1∼2ppm 농도로 격일로 3회 살포한 결과 1주일후 녹조는 완벽하게 처리되었다.Green algae were sprayed three times every other day at concentrations of 50-60 ppm of allophine and imogolite and 1-2 ppm of active corrosive soil.
이상에서 상술한 바와 같이 본 발명은, 하·폐수, 분뇨의 처리에서 질소, 인과 같은 영양물질과 유기오염물질(BOD 및 COD)의 처리효율을 향상하며, 녹조, 적조에서도 질소, 인과 같은 영양물질의 제거효율이 우수하기 때문에 이들 분야에 널리이용될 것으로 기대된다.As described above, the present invention improves the treatment efficiency of nutrients such as nitrogen and phosphorus and organic pollutants (BOD and COD) in the treatment of sewage, wastewater and manure, and nutrients such as nitrogen and phosphorus in green algae and red tide. Because of its excellent removal efficiency, it is expected to be widely used in these fields.
