폐기물을 이용한 하,폐수 처리용 다공성 담체 및 그 제조방법{POROUS CERAMIC MEDIA FOR WASTEWATER TREATMENT USING WASTES AND MANUFACTURING PROCESS OF THE SAME}POROUS CERAMIC MEDIA FOR WASTEWATER TREATMENT USING WASTES AND MANUFACTURING PROCESS OF THE SAME

본 발명은 폐기물을 이용한 하,폐수처리용 다공성 담체 및 그 제조방법에 관한 것으로서, 더욱 상세하게는 각종 하,폐수를 처리하기 위하여 미생물을 용이하게 부착, 성장시킬 수 있고 폐기물이 주성분인 폐기물을 이용한 하,폐수처리용 다공성 담체 및 그 제조방법에 관한 것이다.The present invention relates to a porous carrier for treating sewage and wastewater using waste, and more particularly, to a microorganism easily attached and grown for treating various wastewater and wastewater. The present invention relates to a porous carrier for wastewater treatment and a method of manufacturing the same.

급속한 산업의 발달과 도시 인구의 폭증으로 인한 각종 산업 폐수, 생활 하,폐수와 정화조 폐수 그리고 축산폐수의 배출량이 증가함에 따라서 각종 환경문제 특히 수질오염이 극심해지고 사회적인 문제점으로 대두됨에 따라서 경제적이고 효율적인 하,폐수처리 방법의 개발이 요구되고 있다. 각종 하,폐수에는 많은 오염물질이 함유되어 있어서 pH의 조절과 일부 유해물질의 제거와 같은 화학적인 방법이 요구되며 또한 각종 오염물질을 분해하기 위하여 필수적인 다량의 산소가 필요하고 최근 문제시되고 있는 질소나 인과 같은 영양염류가 많이 함유되어서 하천이나 호수 그리고 연안바다의 부영양화(녹조 및 적조 등)의 원인물질의 제거가 요망된다.With the rapid development of industry and the increase of urban population, the discharge of various industrial wastes, domestic wastes, wastewater and septic tanks, and livestock wastes increases, causing various environmental problems, especially water pollution, and social problems. Development of wastewater treatment methods is required. Since various sewage and waste water contain many pollutants, chemical methods such as controlling the pH and removing some harmful substances are required. Also, a large amount of oxygen is required to decompose various pollutants and nitrogen, which is a problem recently, It is high in nutrients such as phosphorus, so it is necessary to remove the causative agents of eutrophication (green algae and red algae) of rivers, lakes and coastal seas.

pH가 과도하게 중성에서 벗어나거나 유해성분이 함유된 산업폐수외에는 각종 하,폐수처리시 생물학적인 방법이 가장 효율적인 것으로 알려져 있으며 생물학적인 방법은 활성슬러지 공법과 생물막 공법으로 대별할 수 있다. 활성슬러지 공법은 처리대상의 하,폐수에 유용한 각종 미생물을 투입, 현탁상태로 부유시켜서 미생물이 하,폐수중의 오염물질을 처리하도록 하는 방법으로서 혐기조, 무산소조 및 폭기조(산소공급)등에 적용할 수 있다. 이러한 활성 슬러지 공법은 대량의 하,폐수를 저렴하게 처리할 수 있는 장점이 있으나 반응조의 미생물 농도가 낮으므로 처리속도가 느리고 처리시간이 길어지므로 다량의 미생물을 확보하기 위하여 대용량의 처리조가 필요하게 되므로 초기 설비 투자비가 높고 슬러지의 팽화현상 발생 및 다량의 잉여 슬러지의 발생으로 인한 그 처리비용의 급증현상이 초래되며 유입 하,폐수의 부하변동에 대한 대처능력이 미흡한 것 등과 같은 문제점이 발생한다.Except for industrial wastewater containing excessively neutral pH or containing harmful components, biological methods are known to be most effective in treating various wastewater and wastewater, and biological methods can be roughly classified into activated sludge method and biofilm method. Activated sludge method is a method to put microorganisms useful for sewage and wastewater to be treated and suspended in suspended state so that microorganisms can treat contaminants in sewage and wastewater, and can be applied to anaerobic tank, anaerobic tank and aeration tank (oxygen supply). have. This activated sludge process has the advantage of treating large quantities of sewage and wastewater at low cost, but because the concentration of microorganisms in the reaction tank is low, the processing speed is slow and the processing time is long, so a large capacity treatment tank is needed to secure a large amount of microorganisms. Problems include high initial capital investment costs, sludge swelling and a large amount of excess sludge, resulting in a sharp increase in the cost of treatment, and insufficient ability to cope with load fluctuations of inflow and wastewater.

이와같은 문제점들은 본 발명에서 제시하는 생물막법에 의해서 해결될 수 있으며 담체의 구입가격 소요가 문제점이지만 상기와 같은 문제해결 능력때문에 점차 각광을 받고 있고 설치장소가 증가하고 있는 실정이다. 생물막법은 특히 최근 부영양화의 문제점으로 지적되고 있어서 규제강화가 예상되는 총질소와 총인, 특히 총질소의 함유량을 감소, 해결할 수 있는 방안이다. 생물막법은 폭기조(혐기조 및 무산소조에도 설치가능함)내에 미생물 담체를 적당량 충전(약20∼30%)하여 미생물이 생장공간이 많은 표면과 기공에 대량으로 담체에 부착돼서 하,폐수를 처리하게된다. 따라서 보다 많은 종류의 미생물이 안정되게 대량으로 담체에 부착, 생장하면서 하,폐수를 처리하게 되며 다음 공정조로의 미생물 유출이 적어지고 담체의 일부 조성이 미생물의 영양원이 됨으로써 미생물의 생장조건이 우수하므로 하,폐수 처리작용이 활발하게 된다. 그러므로 유입폐수의 수량 및 수질변동에 능동적으로 대처할 수 있고 미생물의 유출이 적어서 미생물을 계속 사용할 수 있으므로 처리효율이 높다.These problems can be solved by the biofilm method proposed in the present invention, but the purchase price of the carrier is a problem, but due to the problem solving ability as described above, the situation is increasing in the installation place. In particular, the biofilm method has recently been pointed out as a problem of eutrophication, and it is a way to reduce and solve the content of total nitrogen and total phosphorus, especially total nitrogen, which is expected to strengthen regulations. The biofilm method fills an appropriate amount (about 20-30%) of microbial carriers in an aeration tank (which can be installed in an anaerobic tank and an anaerobic tank), and microorganisms are attached to the carrier in large quantities on surfaces and pores with a large growth space to treat sewage and wastewater. Therefore, more and more microorganisms are stably attached to the carrier in large quantities and grow, treating sewage and wastewater, and less microbial outflow to the next process tank, and some of the composition of the carrier becomes a nutrient source for microorganisms, so the growth conditions of microorganisms are excellent. Wastewater treatment will be active. Therefore, it is able to actively cope with the fluctuation of quantity and water quality of the inflow wastewater, and the microorganisms can be used continuously because there is little outflow of microorganisms, so the treatment efficiency is high.

미생물 담체의 재질로는 유기물계와 무기물계가 있으며 유기물로는 셀룰로오즈, 폴리에틸렌, 폴리프로필렌 및 폴리염화비닐 등과 같은 각종 고분자 재질이 있으며 무기물로는 각종 화인세라믹과 광물, 유리, 모래, 자갈 그리고 활성탄소등이 이용되고 있다. 유기물 재질은 미생물의 영양원을 제공할 수는 없고 다만 미생물의 부착 및 생장공간만을 제공하게 되므로 무기물 재질보다 성능이 떨어지며 재료자체가 시간의 경과에 따라서 팽윤되거나 열화되어 담체의 특성이 변질되고 부착된 미생물의 탈리가 빈번하게 발생할 뿐만 아니라 슬러지 발생량이 많고 폐기시 공해물질이므로 그 처리가 곤란한 단점이 있으나 가격이 비교적 저렴한 장점이 있다.Microbial carriers include organic and inorganic materials, and organic materials include various polymer materials such as cellulose, polyethylene, polypropylene, and polyvinyl chloride.Inorganic materials include various kinds of fine ceramics, minerals, glass, sand, gravel, and activated carbon. It is used. Organic materials cannot provide nutrients for microorganisms, but they provide only microorganism attachment and growth spaces, so they are inferior to inorganic materials, and the material itself swells or deteriorates over time, resulting in deteriorated carrier characteristics and adhered microorganisms. Desorption occurs frequently, as well as a large amount of sludge generated and pollutants disposed of, so the treatment is difficult, but the price is relatively inexpensive.

모래와 자갈은 지금도 일부에서 사용하고 있지만 폐수처리 공정개발의 초기에 사용했으며 값은 저렴하지만 미생물 생장공간이 적고, 활성탄소는 성능은 양호하지만 가격이 고가이고 대개 분말상태로 사용하게 되므로 계속 투입해야 하며 탄소외에는 다른 미생물영양원이 없는 단점이 있다. 이 3종을 제외한 다른 무기물 재질은 내열성, 내화학성 및 내구성이 우수하고 미생물의 영양원을 제공할 수 있으며 기공크기가 다양하고 그 수가 많아서 다양한 생장공간이 존재하며 토양과 유사한 성분이므로 사용후 폐기시 문제점이 없다는 장점이 있으나 고온소성 공정때문에가격이 유기물에 비해서 고가라는 단점이 있다. 따라서 저온 소성공정을 채택하고 각종 폐기물을 활용해서 가격을 저하시킬 수 있는, 무기물 담체의 개발이 요망된다.Although sand and gravel are still used in some parts of the world, they were used in the early stages of wastewater treatment process development. They are inexpensive but have low microbial growth space, and activated carbon has good performance but is expensive and usually used in powder form. And there is a disadvantage that there is no other microbial nutrient source other than carbon. Inorganic materials other than these three are excellent in heat resistance, chemical resistance and durability, can provide nutrients of microorganisms, and have various growth spaces due to the variety of pore size and number, and are similar to soil, so they are not disposed of after use. There is no merit but there is a disadvantage that price is higher than organic matter because of high temperature firing process. Therefore, it is desirable to develop an inorganic carrier that can adopt a low temperature firing process and utilize various wastes to lower the price.

또한 유기질 담체는 기공수가 많지만 기공크기가 거의 일정해서 다양한 미생물이 부착하는데 문제가 있고 미생물의 영양원이 되는 물질이 거의 없다는 단점이 있다.In addition, the organic carrier has a number of pores, but the pore size is almost constant, there is a problem in that the various microorganisms are attached, there is a disadvantage that there is almost no substance that is a nutrient source of the microorganism.

석탄회는 분상으로 된 유연탄이나 무연탄을 사용하는 화력발전소에서 부산물로 생성되는 플라이 애쉬를 지칭하며, 일부는 콘크리트용 시멘트 대용재로 활용되고 있지만 아직도 대부분을 매립하고 있으며 분진 발생 및 수질 오염을 야기시킴으로써 사회적인 문제점으로 대두되고 있다. 산화규소(SiO2)와 산화알루미늄(Al2O3)이 주성분이며, 그밖에 산화칼슘(CaO), 산화철(Fe2O3), 산화마그네슘(MgO), 산화칼륨(K2O), 산화티탄(TiO2), 산화나트륨(Na2O)과 산화망간(MnO) 등이 함유돼 있으며, 미연탄소분이 약 5% 포함되어 있고 담체 조성으로서 적합한 물질이다.Fly ash refers to fly ash produced as a by-product from coal-fired or anthracite coal-fired power plants, some of which are used as cement substitutes for concrete, but are still landfilled and cause social and dust pollution.
