Zusammenfassung:	The present invention relates to a method for manufacturing a porous ceramic carrier by using inorganic sludge and organic sludge. The manufacturing method, which is a method for manufacturing a porous ceramic carrier using a sludge mixture of inorganic sludge and organic sludge, includes: a step of forming a sludge mixture by mixing 5% to 30% of organic sludge with the inorganic sludge in terms of volumetric ratio; a step of molding and drying the sludge mixture; and a step of sintering the molded body of the sludge mixture. The sludge mixture further contains 35 to 100 parts by weight of clay with respect to 100 parts by weight of the inorganic sludge. According to the manufacturing method, a high-quality and inexpensive ceramic carrier can be manufactured through a simple process and by the use of the inorganic sludge and the organic sludge. In addition, the manufacturing method can be advantageously applied as a method for handling and recycling the inorganic sludge such as stone powder sludge, which is limited in recycling due to technical limitations and high costs, and the organic sludge, which causes environmental pollution. Furthermore, the present invention can result in the manufacturing of a porous ceramic carrier excellent in porosity, sinterability, and strength with respect to stone powder sludge containing a large quantity of specific component such as calcium oxide (CaO). 본 발명은 무기성 오니 및 유기성 오니를 이용하여 다공성의 세라믹 담체를 제조하는 방법에 관한다. 상기 제조 방법은, 무기성 오니 및 유기성 오니의 오니 혼합물을 이용한 다공질 세라믹 담체 제조 방법에 있어서, 상기 무기성 오니에 부피비로 5~30%의 유기성 오니를 혼합하여 오니 혼합물을 형성하는 단계; 상기 오니 혼합물을 성형 건조하는 단계; 및 상기 오니 혼합물의 성형체를 소결시키는 단계를 포함하고, 상기 오니 혼합물은 상기 무기성 오니 100 중량부에 대해 35 ~ 100 중량부의 점토를 더 포함하는 것을 특징으로 한다. 이러한 제조 방법은, 무기성 오니와 유기성 오니를 이용하여 간단한 공정으로 저비용 고품질의 세라믹 담체를 제조하는 것이 가능하여, 종래 기술적인 한계와 고비용으로 인해 재활용이 제한적인 석분 슬러지와 같은 무기성 오니와 환경 오염의 원인이 되는 유기성 오니를 처리 및 재활용하는 방법으로서 유리하게 적용될 수 있다. 특히 본 발명은, 산화칼슘(CaO)과 같은 특정 성분을 다량으로 함유하고 있는 석분 슬러지에 대해서도 기공률, 소결성 및 강도가 우수한 다공성 세라믹 담체를 제조하는 것이 가능하다.
