Abstract

본 발명은 고농도 유기 물질을 함유하는 폐수를 처리하는데 적합한 미생물 부착 능력이 향상된 높은 기공율과 비표면적을 가지는 ALC계 다공성 담체를 제조하는 방법을 제공하기 위한 것이다.The present invention is to provide a method for producing an ALC-based porous carrier having high porosity and specific surface area with improved microbial adhesion ability suitable for treating wastewater containing high concentration organic materials.

본 발명에 따른 담체는 다공성 세라믹을 실리카 졸에 침지시키고 진공 코팅법에 의해 실리카를 코팅하여서 제조한다.The carrier according to the invention is prepared by immersing a porous ceramic in a silica sol and coating silica by vacuum coating.

본 발명의 실리카 졸이 코팅된 담체는 높은 다공성을 가지므로 미생물을 고농도로 부착시킬 수 있으며, 반응조 내에서 미생물을 고농도로 유지할 수 있기 때문에 고농도의 유기 물질을 함유하는 각종 폐수를 경제적이면서 효율적으로 처리할 수 있다.Since the silica sol coated carrier of the present invention has high porosity, microorganisms can be attached at high concentration, and microorganisms can be maintained at high concentration in a reaction tank, so that various wastewater containing high concentration of organic materials can be treated economically and efficiently. can do.
