본 발명의 주성분인 불석족 광물로는 나트로라이트(Natrolite)[Na2Al2SiO10·2H2O], 로우몬타이트(Laumontite)[CaAl2Si4O12·4H2O], 스틸바이트(Stilbite)[Ca(Al2Si7O18)·7H2O], 카바자이트(Chabazite)[CaAl2Si4O12·6H2O], 메솔라이트(Mesolite)[Na2Ca2Al6Si9O30·8H2O], 톰소나이트(Thomsonite)[NaCa2Al5Si5O20·6H2O] 등이 있으며, 본 발명의 조성물에는 전기 열거한 불석족 광물중 어떠한 것을 사용하여도 무방하며 1종 이상을 병용할 수 있다. 상기 불석족 광물들은 중부이남지역의 반려암, 현무암 등에 무진장 함유되어 있으며, 주로 섬유상 또는 주상으로 방사상 집합체를 구성하고 있고, 염기성 함수규산염으로 되어 있다. 불석족 광물들은 SiO2-Al2O3를 주성분으로 한 제올라이트계 광물질로서, 통상, 분자의 결정 격자내에 함유되어 있는 수분이 증발하여도 그 결정구조가 고온에서 파괴되지 않고 유지되어 여기에 직경 3~10Å의 미세다공이 형성됨으로써 이 자체가 필터역할을 하여 폐수중의 3~10Å 크기의 유기 또는 무기물질들을 선별하여 흡착 또는 여과시키는 분자체(Molecular-Sieve)역할을 함으로써 폐수등의 오염물질들을 흡착, 여과, 응집 및 침전과정을 통해 처리할 수 있도록 하여 준다.The main fluoride minerals of the present invention include Natrolite [Na 2 Al 2 SiO 10 .2H 2 O], Laumontite [CaAl 2 Si 4 O 12 .4H 2 O], steel bite. (Stilbite) [Ca (Al 2 Si 7 O 18) · 7H 2 O], carbazole ZUID (Chabazite) [CaAl 2 Si 4 O 12 · 6H 2 O], methoxy solrayiteu (Mesolite) [Na 2 Ca 2 Al 6 Si 9 O 30 .8H 2 O], Tomsonite [NaCa 2 Al 5 Si 5 O 20 .6H 2 O], and the like. The composition of the present invention may be used with any of the fluorinated minerals listed above. It is good to use one or more types together. The fluorite minerals are inexhaustibly contained in the sub-central region of the basalt, basalt, etc., mainly composed of a fibrous or columnar radial aggregate, and is composed of basic hydrous silicates. Unstable minerals are zeolite-based minerals mainly composed of SiO 2 -Al 2 O 3. In general, even when moisture contained in the crystal lattice of a molecule evaporates, the crystal structure is maintained at high temperature so that the crystal structure is not broken. By forming micropores of ~ 10Å, it acts as a filter, and acts as a molecular sieve to select and adsorb or filter 3 ~ 10 3 of organic or inorganic substances in the wastewater. It can be treated by adsorption, filtration, flocculation and precipitation.
본 발명의 조성물의 또 다른 성분인 몬모릴로나이트는 SiO2약 59%, Al2O3약 14%, Na2O 약 3.5% 함유하고 있는 SiO2-Al2O3성분계 광물로서, 국내의 장석 또는 점토류 광물중에 널리 분포되어 있으며, SiO2-Al2O3성분계 광물의 특징인 다공성에 의한 흡착작용과 이온교환작용을 통해 불석족 광물과 병용시, 상호보완작용을 한다.Montmorillonite, another component of the composition of the present invention, is a SiO 2 -Al 2 O 3 component mineral containing about 59% SiO 2 , about 14% Al 2 O 3 , and about 3.5% Na 2 O. It is widely distributed among other minerals, and complementary when combined with non-fluoride minerals through adsorption and ion exchange by porosity, which is characteristic of SiO 2 -Al 2 O 3 component minerals.
또한, 몬모릴로나이트는 물에 용해되지 않지만, 수용액중의 수분을 흡수하여 입자크기의 8~12배 정도로 팽윤하는 성질이 있어 이를 통해 오염물 흡착의 상호보완작용을 한다.In addition, montmorillonite does not dissolve in water, but absorbs moisture in an aqueous solution and swells to about 8 to 12 times the particle size, thereby complementing the adsorption of contaminants.
본 발명의 조성물의 또 다른 성분인 소석회[Ca(OH)2]는 용액중에서 CO 또는 CO2기체등과 반응하여 CaCO3를 형성함으로써 탈취작용 및 색도감소작용을 한다.Calcined lime [Ca (OH) 2 ], which is another component of the composition of the present invention, reacts with CO or CO 2 gas and the like in the solution to form CaCO 3 , thereby deodorizing and reducing the color.
또한, 소석회는 농업용 토지 및 기타 산업시설물에 악영향을 미치는 폐산수를 중화시키는 역할을 한다.In addition, slaked lime neutralizes wastewater that adversely affects agricultural land and other industrial facilities.
본 발명의 조성물의 또 다른 성분인 황산반토는 응집제로서의 역할을 수행하도록 첨가된 성분이며, 또한 촉매제는 오염물의 흡착, 침전 및 응집을 촉진시키기 위하여 첨가된 성분으로서 본 발명의 조성물의 상기 성분들과 유기적으로 상호 보완하여 폐수처리효과를 극대화하는 효과를 발휘한다.Another component of the composition of the present invention, alumina sulfate, is a component added to perform a role as a flocculant, and a catalyst is a component added to promote the adsorption, precipitation and flocculation of contaminants. It complements organically to maximize the effect of wastewater treatment.
본 발명의 또 다른 성분인 황산 제2철은 안료, 자성재료로서 사용할 수 있는 성질을 지니고 있으므로, 환원 흡착과정을 통해 염색폐수의 색소를 제거하여 폐수의 색도를 저하시켜 주는 역할을 한다.Ferric sulfate, which is another component of the present invention, has a property that can be used as a pigment and a magnetic material, thereby reducing the chromaticity of the wastewater by removing dyes of the dyeing wastewater through a reduction adsorption process.
상기와 같은 성분들로 구성된 본 발명의 조성물은 탈취기능과 아울러 COD, BOD, SS 및 색도를 현저하게 저하시키는 효과가 있다.The composition of the present invention composed of the above components has the effect of significantly lowering COD, BOD, SS and chromaticity as well as deodorizing function.
이하, 본 발명을 제조예 및 실시예를 참고로 하여 보다 상세히 설명하였으나, 본 발명의 범위가 실시예에만 한정되지는 않는다.Hereinafter, the present invention has been described in more detail with reference to Preparation Examples and Examples, but the scope of the present invention is not limited only to the Examples.
