본 발명은 황토, 점토, 백토 및 고령토로 이루어진 여재원료 및 음식물쓰레기, 유기성폐기물, 산업용폐기물로 이루어진 다공성 세라믹 제조방법에 관한 것으로, 더욱 상세하게는 여재원료를 황토, 백토, 점토 및 고령토로서 준비하고 이 준비된 여재 원료에 음식물 쓰레기, 유기성폐기물 또는 산업용폐기물로 이루어진 발포제를 일정함량 혼합하여 제조되는 다공성 세라믹을 제공함으로서, 미생물과의 친화력을 극대화 시키는 동시에 오폐수 처리 효율이 극대화 될수 있도록 한 황토, 점토, 백토 및 고령토로 이루어진 여재원료 및 음식물쓰레기, 유기성폐기물, 산업용폐기물로 이루어진 다공성 세라믹 제조방법에 관한 것이다. The present invention relates to a method for producing a porous ceramic consisting of loess, clay, clay and kaolin and food waste, organic waste, industrial waste, and more particularly, preparing a raw material as loess, clay, clay and kaolin. By providing a porous ceramic prepared by mixing a predetermined amount of blowing agent consisting of food waste, organic waste or industrial waste to the prepared raw material, it is possible to maximize the affinity with microorganisms and at the same time to maximize the efficiency of wastewater treatment. And it relates to a method for producing a porous ceramic consisting of the raw material and food waste, organic waste, industrial waste consisting of kaolin.

일반적으로 토양과 하천 및 상수원등의 수질오염은 일상상활에서 배출하는 생활폐수 및 각종 공장을 비롯하여 실험실, 연구소 등의 산업 현장에서 발생되는 각종 오,폐수에서 비롯되고 있다.In general, water pollution such as soil, rivers, and water supplies originates from various wastewater and wastewater generated in industrial sites such as laboratories and research institutes, as well as domestic wastewater discharged from daily activities.

이러한 각종 오폐수를 처리하고자 할 때에는 생물학적 처리공법이 널리 이용되고 있으며, 상기의 생물학적 처리공법은 미생물을 배양시켜 각종 오염물질을 제거하게 되며, 이 배양된 미생물은 여재에 접촉되어 오폐수의 유기물을 섭취 제거하는 형태로서 오염물질을 제거하게 된다.When treating various kinds of wastewater, biological treatment methods are widely used, and the biological treatment method is a method of culturing microorganisms to remove various contaminants, and the cultured microorganisms come into contact with the media to ingest and remove organic matter from wastewater. As a result, the pollutants are removed.

이때 가장 중요한 역할을 수행하는 것은 미생물이 서식할수 있도록 제공되는 여재와 이 여재에 생성되는 미생물막을 포함하는 미생물 담체인 것이다.At this time, the most important role is the microbial carrier including the filter medium provided to inhabit the microorganisms and the microbial film generated in the filter medium.

상기의 폐수를 처리하게 되는 미생물 담체는 직육면체 또는 정육면체등과 같이 일정형상을 이루면서 접촉 폭기조 내의 한정된 공간에 불규칙한 배열을 갖고 채워지게 된다. The microbial carrier for treating the wastewater is filled with an irregular arrangement in a limited space in the contact aeration tank while forming a certain shape such as a cube or a cube.

그리고 이러한 종래의 미생물 담체는 이제까지 천연암석이나 인조 플라스틱으로서 제공되어 왔으며, 이로 인해 표면적이 적게 됨은 물론 표면 공극이 없게 되는 미생물 담체가 구성되는 것일 뿐 만 아니라 미생물과의 친화력이 작아 부착된 미생물이 이탈되는 탈리현상이 쉽게 일어나는 문제점이 있었으며, 이렇게 여재상에서 쉽게 미생물이 박리되어 탈리됨으로 인해 미생물 배양에는 그 만큼 많은 시간이 소요되는 문제점이 있었고, 또한 완전한 미생물 담체를 이루는 데도 많은 시간이 소요됨은 물론 배양된 미생물의 탈리로 인하여 양호한 폐수처리를 기대할 수 없는 것일 뿐만 아니라 그만큼 오폐수 처리효율도 떨어지게 되고 처리된 수질도 악화되기 쉬운 문제점이 있는 등 여러가지 제반 문제점들이 발생되었다. In addition, such conventional microbial carriers have been provided as natural rocks or artificial plastics, and thus, not only the surface area is reduced, but also the microbial carriers are formed without surface voids, and the microorganisms attached to the microorganisms have a small affinity with the microorganisms, thereby leaving the attached microorganisms. There was a problem that the desorption phenomenon easily occurs, and because the microorganisms are easily detached and detached from the filter medium, it takes a lot of time to grow the microorganisms, and also takes a long time to form a complete microbial carrier. Due to the desorption of microorganisms, not only good wastewater treatment cannot be expected but also various wastewater treatment efficiency is lowered and the treated water quality tends to deteriorate.

따라서 본 발명의 목적은 상기와 같은 종래의 문제점을 감안하여 안출한 것으로, 여재 원료를 황토, 백토, 점토 및 고령토로서 준비하고 이 준비된 여재 원료에 음식물 쓰레기, 유기성폐기물 또는 산업용폐기물로 이루어진 발포제를 일정함량 혼합하여 제조되는 다공성 세라믹을 제공함으로서, 다공성의 여재를 이룸과 동시에 미생물과의 친화력을 극대화 시키는 것임은 물론 여재상에 신속하고도 안정적인 다공성 세라믹이 배양되는 것일 뿐만 아니라 오폐수 처리 효율이 극대화 될수 있도록 한 황토, 점토, 백토 및 고령토로 이루어진 여재원료 및 음식물쓰레기, 유기성폐기물, 산업용폐기물로 이루어진 다공성 세라믹 제조방법을 제공하는데 있다.Accordingly, an object of the present invention is to devise in view of the conventional problems as described above, preparing a raw material as a loess, clay, clay and kaolin and a predetermined amount of blowing agent consisting of food waste, organic waste or industrial waste to the prepared raw material By providing a porous ceramic manufactured by mixing the contents, it not only maximizes the affinity with microorganisms at the same time as the porous media, but also enables the rapid and stable porous ceramics to be cultured on the media as well as to maximize wastewater treatment efficiency. The present invention provides a method for producing a porous ceramic comprising a raw material consisting of loess, clay, clay and kaolin and food waste, organic waste, and industrial waste.

상기와 같은 목적을 달성하기 위한 수단으로 본 발명은, 황토, 점토, 백토 및 고령토로 이루어진 여재원료 및 음식물 쓰레기, 유기성폐기물 또는 산업용폐기물로 이루어진 발포제 구성되는 것을 그 기술적 구성상의 기본 특징으로 한다.As a means for achieving the above object, the present invention is characterized in that the basic composition of the technical composition is composed of a raw material consisting of loess, clay, clay and kaolin and a blowing agent consisting of food waste, organic waste or industrial waste.

이하 본 발명의 바람직한 실시예를 보다 상세하게 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described in detail.

본 발명의 다공성 세라믹은 이후 다공성 세라믹으로서 기술되고 설명될 것이나, 이는 각종 오수, 하수 또는 폐수처리 방법에서 미생물을 이용한 처리에 모두 적용될수 있는 것임은 물론 하천 정비 정화용 블록이나 방음항습자재 및 경량골재등의 건축자재로서도 사용될수 있는 것이다.Porous ceramics of the present invention will be described and described later as a porous ceramic, which can be applied to all treatments using microorganisms in various sewage, sewage or wastewater treatment methods, as well as the stream maintenance purification block or soundproof humidity and moisture materials and lightweight aggregates, etc. It can also be used as a building material.

여기에서 상기 건축용 경량자재나 하천정비 정화용 블록 및 방음항습용 블록으로 제조시에는 하기에 설명될 본 발명의 다공성 세라믹의 입경이 0.1~1000mm이고 밀도는 0.5∼2.0g/m3로서 이루어 제조되는 것이 바람직하다.Herein, when manufacturing the building lightweight material or the stream maintenance purification block and the soundproof humidity block, the particle diameter of the porous ceramic of the present invention to be described below is 0.1 to 1000 mm and the density is made to be 0.5 to 2.0 g / m 3 . desirable.

그리고 본 발명의 다공성 세라믹은 여재원료 및 발포제로 구성되는 것이다.And the porous ceramic of the present invention is composed of a filter material and a blowing agent.

상기한 여재 원료로는 황토를 주성분으로 하여 첨가됨과 동시에 여재가 일정강도와 내구성을 가질수 있도록 보조성분으로서 백토, 점토 및 고령토가 각각 일정비율을 이루어 첨가된다.As the filter material, ocher is added as a main component, and at the same time, clay, clay, and kaolin are added as a secondary component so that the filter medium has a certain strength and durability.

한편 상기 미생물 여재상에는 다량의 미생물이 흡착되어 미생물 막이 형성되며, 그 막이 형성되는 상부 호기성층에서는 유기 오염물의 호기성 산화와 질산화가 일어나서 유기물질을 제거하게 되고, 하부 혐기성층과 기공내부에 존재하는 미생물에 의하여 혐기성산화와 탈질화반응이 일어나서 질소성분을 효과적으로 제거할 수 있다.Meanwhile, a large amount of microorganisms are adsorbed on the microbial mediator to form a microbial membrane, and in the upper aerobic layer in which the membrane is formed, aerobic oxidation and nitrification of organic contaminants occur to remove organic substances, and microorganisms present in the lower anaerobic layer and the pores. By the anaerobic oxidation and denitrification reaction can be removed nitrogen effectively.

상기의 본 발명에 따른 다공성 세라믹은 미생물과의 친화력이 극대화 될수 있도록 함과 동시에 미생물등의 탈리 현상이 방지될수 있도록 발포제가 사용되고, 이 발포제로는 음식물 쓰레기, 유기성폐기물, 산업용폐기물이 사용되는 것이며, 그 함량은 전체 접촉여재에 대한 발포제의 함량이 20중량%∼80중량%를 이루도록 된 것이다. In the porous ceramic according to the present invention, a blowing agent is used to maximize the affinity with the microorganism and at the same time prevent desorption of microorganisms, and the blowing agent is food waste, organic waste, industrial waste, and the like. The content is such that the content of the blowing agent relative to the total contact medium is 20% to 80% by weight.

상기에서와 같이 발포제로서 음식물 쓰레기등이 이용됨으로서, 음식물 쓰레기, 유기성폐기물, 산업용폐기물 처리가 자율적이고도 적극적으로 이루어 지게 되어 음식물 쓰레기등의 처리 문제를 해결할수 있게 되는 것임은 물론 발포제로서 음식물 쓰레기를 이용하게 되어 본 발명의 오폐수처리용 다공성 미생물 담체의 제조단가도 절감되는 것임과 동시에 폐자원의 재활용이라는 환경친화적인 제품을 이루게 되는 것이다.여기서, 유기성폐기물은 미생물에 의하여 분해 가능한 유기물을 많이 포함하는 하폐수 슬러지가 사용되고, 산업폐기물은 사업활동에 수반하여 발생되는 슬러지, 폐고무, 폐합성수지가 사용된다.As the above-mentioned food waste is used as a blowing agent, the processing of food waste, organic waste, and industrial waste is autonomous and active, so that it is possible to solve the problem of disposal of food waste, as well as using food waste as a blowing agent. The production cost of the porous microorganism carrier for wastewater treatment of the present invention is reduced, and at the same time, the environmentally friendly product such as recycling of waste resources is achieved. Here, the organic waste is wastewater containing a large amount of organic matter that can be decomposed by microorganisms. Sludge is used, and industrial waste uses sludge, waste rubber, and synthetic resin generated from business activities.

상기 음식물 쓰레기 발포제로 표면부를 이루는 본 발명의 다공성 세라믹은 그 미생물의 친화력을 증대시키면서 배양 속도가 증가되어 그 만큼 미생물막 형성시간이 단축되는 것임과 동시에 일단 형성된 미생물 막은 그 미생물 부착성능이 우수하여 미생물이 박리되어 떨어져 나가는 탈리현상을 방지하게 되고, 이로서 오페수 처리효율을 극대화 되게 되는 것이다.The porous ceramics of the present invention forming the surface portion of the food waste blowing agent have an increased microbial affinity while increasing the affinity of the microorganisms, thereby shortening the microbial membrane formation time. This peeling is to prevent the detachment phenomenon to fall off, thereby maximizing the treatment efficiency of the water operation.
