Description

굴패각이 함유된 수처리용 세라믹 담체와 그 제조방법{THE WASTE WATER TREATING CERAMIC CARRIER WHICH CONTAINS OYSTER SHELL AND THE PRODUCING METHOD OF THEREOF}Ceramic carrier for water treatment containing oyster shell and its manufacturing method {THE WASTE WATER TREATING CERAMIC CARRIER WHICH CONTAINS OYSTER SHELL AND THE PRODUCING METHOD OF THEREOF}

본 발명은 굴패각이 함유된 수처리용 세라믹 담체와 그 제조방법에 관한 것이다.The present invention relates to a ceramic carrier for water treatment containing oyster shells and a method of manufacturing the same.

하·폐수처리 공정에서 적용되고 있는 생물학적인 처리공법은 부유미생물을 이용한 활성슬러지 공법과 고정미생물을 이용한 생물막 공법이 사용되고 있으나, 이 공정의 다음 공정인 침전공정에서 침전효율이 낮기 때문에 높은 처리효율을 얻기 어려운 단점이 있다.The biological treatment method used in sewage and wastewater treatment process is activated sludge process using suspended microorganisms and biofilm process using fixed microorganisms. There is a disadvantage that is difficult to obtain.

한편, 한국특허출원 10-1997-0054054 (굴패각을 이용한 분말형 담체의 제조방법)에서는, 굴패각을 분쇄하여 소성처리하고, 소성처리된 분말을 산처리하여 불순물을 제거하고 동시에 이온교환능을 갖는 활성화된 담체를 얻기 위하여 pH를 조절하여 건조한 다음 수화시키고, 다시 건조하여 분말형 담체를 제조하는 방법이 공지되어 있으나, 분말형 담체를 사용하면 물의 표면에서만 수처리 작용을 수행하게 되어 수중 일정 깊이에 존재하는 오염물질은 제거 할 수 없으며, 실제 하·폐수처리공정에 도입하게 되면 분리회수가 어렵다는 단점을 가지고 있다.On the other hand, in Korean Patent Application No. 10-1997-0054054 (Method for preparing powder type carrier using oyster shell), oyster shell was pulverized and calcined, and the calcined powder was acid treated to remove impurities and at the same time activated with ion exchange ability. In order to obtain a carrier, a method of preparing a powdery carrier by drying it, drying it, and then hydrating it to dryness is known. However, when a powdery carrier is used, water treatment can be performed only on the surface of water, thereby contaminating the water at a certain depth. The material cannot be removed and it is difficult to separate the recovery if it is introduced into the sewage and wastewater treatment process.

또한, 한국특허출원 10-2000-0060530(수처리용 흡착제)에서는, 고온에서 소성 가공하여 분쇄한 다공성으로 이루어진 패각 분말과, 황토, 몬모릴로나이트, 일라이트, 벤토나이트, 맥반석 또는 제올라이트 중의 어느 하나인 다공성 천연 무기물 분말과, 숯 또는 활성탄 중의 어느 하나를 포함하는 탄소 화합물을 구성성분으로 하는 수처리용 흡착제에 관한 것이 공지되어 있으나, 구성 성분이 다양하고 제조공정이 복잡한 단점이 있었다.In addition, in Korean Patent Application No. 10-2000-0060530 (water adsorbent), a shell powder made of porous obtained by plastic working at high temperature and pulverized, and porous natural inorganic material which is any one of ocher, montmorillonite, elite, bentonite, elvan, or zeolite. It is known to adsorbents for water treatment comprising a powder and a carbon compound comprising any one of charcoal or activated carbon, but there are disadvantages in that the composition is diverse and the manufacturing process is complicated.

본 발명에서는 상기 문제점을 개선하기 위해, 하·폐수처리 공정에 사용시 부유 고형물에 대한 침강효과가 좋고, 원료 비용이 저렴하면서도 제조공정이 비교적 간편한, 굴패각이 함유된 수처리용 세라믹 담체와 그 제조방법을 제공하는 데 목적이 있다.In order to improve the above problems, the sedimentation effect on the suspended solids when used in the sewage and wastewater treatment process is good, and the raw material cost is low, but the manufacturing process is relatively simple, containing a oyster shell containing water treatment ceramic carrier and its manufacturing method The purpose is to provide.

본 발명에 의해 굴패각이 함유된 수처리용 세라믹 담체가 제공되며, 이 담체를 생물학적 처리공정에 사용할 경우 활성 슬러지의 침강효과가 높고, 또한 야적 또는 매립에 의해 폐기처리 되고 있는 굴패각을 활용하므로 세라믹 담체의 생산단가를 낮출 수 있다.According to the present invention, there is provided a ceramic carrier for water treatment containing oyster shell, and when the carrier is used in a biological treatment process, it has a high sedimentation effect of activated sludge and also utilizes the oyster shell that has been disposed of by yard or landfill. The production cost can be lowered.
