Description

오폐수 정화용 소재의 제조방법Manufacturing method of wastewater purification material

본 발명은 오폐수를 최소의 시설비와 운영비로서 정화처리키 위한 정화용 소재의 제조방법에 관한 것이다.The present invention relates to a method for producing a material for purification to purify waste water with minimum facility and operating costs.

근자에 전세계적으로 물질 문명사회의 산업고도화 지향에 필연적으로 따르는 각종 폐기물의 발생으로 자연환경이 오염되고, 생태계가 파괴되는 등 극심한 폐해로 인해 인류의 생존권마저 위협되고 있으며, 특히 폐기물로 인한 수질오염은 그 정도가 극심하여 날로 늘어나는 생활폐수, 축산물 폐수, 공장폐수등은 모든 하천과 지하수를 오염시켜 자연환경 및 생태계는 물론 식용수, 산업용수의 고갈시대를 맞게 되었고, 이를 해결하기 위해 우리나라를 비롯한 세계 각국에서 천문학적인 경비와 첨단장비를 투자하여 끊임없는 연구개발을 시도하고 있다.In the near future, human rights are being threatened by extreme damage such as pollution of natural environment and destruction of ecosystem due to the generation of various wastes that are inevitably followed by industrial advancement of material civilization society, especially water pollution caused by waste. The amount of living wastewater, livestock waste, and factory wastewater, which are increasing day by day, have contaminated all rivers and groundwater, resulting in the depletion of drinking water and industrial water as well as natural environments and ecosystems. Investing in astronomical expenses and high-tech equipment from all over the world, we are constantly trying to research and develop.

기존에 개발된 오폐수 정화처리방법은 활성오니방식, 즉 일반적으로 화학적 처리방법, 물리적 처리방법, 샘물학적 처리방법으로 구분된다.The previously developed waste water purification treatment methods are classified into activated sludge methods, that is, chemical treatment methods, physical treatment methods, and spring water treatment methods.

그러나 전기한 기존의 처리방법 중 화학적 처리방법은 처리과정에서의 처리약품 특정으로 인하여 2차 공해뿐만 아니라 폐수의 수질변화에 따라 투입하는 시약량 조절이 불가능하므로 불완전한 정수처리로 인한 공해를 심히 유발하며, 특히 엄청난 약품처리 비용이 과다한 문제가 있고, 물리적 처리방법 역시 처리효율에 한계성이 있으며 처리방법 및 유지관리가 매우 어렵고 복잡하며, 처리시간에 비례하여 처리효율이 저하되는 단점이 있고, 특히 이온상태의 극히 작은 오염물질을 처리 제거하는데 문제가 있다.However, the chemical treatment method among the existing treatment methods cannot control the amount of reagent input due to the change of the water quality of the wastewater as well as the secondary pollution due to the specific treatment chemicals in the treatment process, causing severe pollution due to incomplete water treatment. In particular, there is a problem that excessive chemical treatment costs are excessive, physical treatment methods also have limitations in treatment efficiency, treatment methods and maintenance are very difficult and complicated, and treatment efficiency decreases in proportion to treatment time, in particular in an ionic state. There is a problem with processing and removing very small pollutants.

또 생물학적 처리방법은 폐수내 유기물질 처리에 국한되고, 유기물질 중에서도 처리 불가능한 것은 방치하는 실정일 뿐 아니라 처리 미생물이 호기성, 혐기성으로 구분되어 처리 관리가 매우 어려우며, 유입폐수의 다각적인 특성유무, 온도변화에 따라 처리한계가 있으며, 처리 시설면적이 방대하여 유지관리비가 과다하므로 비경제적인 문제가 있다.In addition, the biological treatment method is limited to the treatment of organic substances in wastewater, and the treatment of organic substances in the wastewater is not allowed, and treatment microorganisms are classified into aerobic and anaerobic. There is a treatment limit according to the change, and there is an uneconomical problem because the treatment facility is huge and the maintenance cost is excessive.

본 발명은 오폐수를 정화 처리함에 있어서, 전기한 바와 같은 문제점을 제거코저 각종 폐수를 본 발명의 세라믹스입자와 활성탄이 혼합된 소재를 통과시켜 이온 전리에 의해 분자의 연결고리를 분리 산화시켜 비교적 저렴한 설치비와 운영비로 정화 처리효율을 높히므로서 각종 폐수 자체가 자체 정화능력을 갖는 양질의 자연수로 환원되게 한 오페수 정화용 필터 소재의 제조방법을 제공함에 그 발명의 목적이 있다.The present invention eliminates the problems as described above in purifying wastewater. Various wastewater is passed through a material mixed with the ceramic particles and activated carbon of the present invention to separate and oxidize the linkage of molecules by ion ionization. It is an object of the present invention to provide a method for producing a filter material for purification of ope water by reducing various wastewater itself to high-quality natural water having its own purification capacity while increasing the purification treatment efficiency with the operating cost.

이하, 본 발명의 실시예를 상세히 실명한다.Hereinafter, the embodiment of the present invention in detail.

본 발명의 정화용 소재는 고령토(30∼50%), 규사(15∼25%), 톱밥(30∼50%)이 혼합 소성되어 다공질화된 세라믹입자와 활성탄이 1:1로 혼합 형성되어 있다.In the purification material of the present invention, kaolin (30-50%), silica sand (15-25%) and sawdust (30-50%) are mixed and calcined to form porous ceramic particles and activated carbon 1: 1.

전기한 정화용 소재의 제조방법을 설명한다.The manufacturing method of the purification material mentioned above is demonstrated.

먼저 부피비율로서 고령토 30∼50%, 규사 15∼25%, 톱밥 30∼50%를 혼합한 후 그 혼합물에 물을 전체를 백분율로 할 때 40∼50% 첨가하여 반죽한다.First, kaolin is mixed with 30-50% of kaolin, 15-25% of silica sand and 30-50% of sawdust, and then kneaded by adding 40-50% of water to the mixture as a percentage.

반죽된 점토를 블록상으로 성형하여 이를 1300℃의 온도로 1시간 정도 가열 소성시킨 후 자연 냉각시킨다.The kneaded clay is molded into blocks, heated and calcined at a temperature of 1300 ° C. for about 1 hour, and then naturally cooled.

이때 톱밥 분말이 조직내에서 소각되어 차지하고 있던 공간이 비게 되어 다공질화된 세라믹이 성형되는 것이다.At this time, the space occupied by incineration of the sawdust powder in the tissue becomes empty, thereby forming a porous ceramic.

전기한 바와 같이 소성 완성된 블록상의 소성물을 분쇄기에 의해 분쇄시켜 2㎤이내의 입자로 형성한다.As described above, the fired block-like fired product is pulverized by a pulverizer to form particles of 2 cm 3 or less.

이와 같이 완성된 다공질 세라믹 입자와 활성탄을 1:1로 혼합하여 최종적인 정화용 소재를 완성하는 것이다.In this way, the porous ceramic particles and activated carbon are mixed 1: 1 to complete the final purification material.

이와 같이 완성된 정화용 소재를 이용하여 오폐수를 정화시키는 정화공정을 설명한다.The purification process for purifying wastewater using the thus completed purification material will be described.

먼저 탱크내에 본 발명의 정화용 소재를 충전한 후 이에 오폐수를 투입하여 산소를 공급하면서 40∼60분간 경과시킨다.First, the purification material of the present invention is filled into the tank, and then, waste water is added thereto and passed for 40 to 60 minutes while supplying oxygen.

이때 다공질 세라믹 입자와 활성탄 및 산소에 의해 오폐수가 이온 전리되면서 오폐수 분자간의 응집력이 와해되어 분자 연결고리가 분해되어 산화된다.At this time, the waste water is ionized by the porous ceramic particles, activated carbon, and oxygen, and thus the cohesion between the waste water molecules is broken, and the molecular link is decomposed and oxidized.

이렇게 산화된 오폐수는 세라믹의 무수한 파공과 활성탄에 1차 정화된 후 다시 이를 본 발명의 소재로 이루어진 필터를 반복하여 통과시키므로서 최종적으로 정화된 정화수를 얻게 된다.The waste water oxidized in this way is purified first through numerous pores and activated carbon of ceramics, and then passes through a filter made of the material of the present invention, and finally purified water is obtained.

실제로 생활폐수를 전기한 공정과 같이 중화 처리한 결과 탁도가 1, 생물학적 산소요구량(BOD)과 화학적 산소요구량(COD)이 5PPM 이내로 된 정화수를 얻을 수 있어 그 생활폐수를 재활용수로 사용 가능하게 되는 것이다.As a result of neutralizing the domestic wastewater in the same way as the electric process, it is possible to obtain purified water with turbidity of 1, biological oxygen demand (BOD) and chemical oxygen demand (COD) within 5PPM. will be.

이상과 같이 본 발명은 최소한의 비용과 설비로서 생활폐수, 축산폐수 및 산업폐수를 2차 공해의 발생없이 거의 자연상태로 복귀되게끔 정화시키므로서 저렴한 비용으로 환경오염을 방지할 수 있는 효과가 있다.As described above, the present invention has the effect of preventing environmental pollution at a low cost by purifying domestic wastewater, animal husbandry wastewater and industrial wastewater to return to almost natural state without the occurrence of secondary pollution as a minimum cost and equipment. .
