Abstract

본 발명은 미생물고정화에 의한 폐수중 PVA 분해 방법 및 장치에 관한 것이다.The present invention relates to a method and apparatus for decomposing PVA in wastewater by microbial immobilization.

PVA는 생물학적 처리시 거의 제거되지 않고 유출되며 PVA 자체가 화학적산호요구량(COD)을 나타내므로 PVA의 제거가 중요한 문제이다.The removal of PVA is an important issue because PVA is effluent almost without biological removal and PVA itself shows chemical coral demand (COD).

현재 가장 많이 사용되고 있는 약품응집 후 활성오니법은 약품소요량이 많으며, 또한 오니의 발생량이 많을 뿐만 아니라 여기에 사용되는 활성 오니조가 너무커서 법적방류수질 기준에 도달하는데 시설비와 운영의 부담이 상당이 크다.The active sludge method after drug aggregation is the most used at present, and there is a large amount of chemical demand, and the sludge generated is large, and the active sludge used here is too large to reach the legal discharge water quality standard, and the burden of facility cost and operation is considerable. .

따라서 이와같은 문제점을 해결하기 위하여 분체입자를 담체로 사용하여 미생물을 고정화시켰으며, 이것을 폭기조에 고농도로 유지하면서 공기 부상이나 교반에 의해서 담체에 부착된 미생물을 이용하여 폐수중 PVA를 분해하는 방법이다.Therefore, in order to solve this problem, microparticles are immobilized by using powder particles as a carrier, and this method is used to decompose PVA in wastewater by using microorganisms attached to the carrier by air floating or agitation while maintaining this in aeration tank. .

폭기조내에 미생물을 고농도로 유지함으로서 높은 수량부하 및 유기물 부하에서도 고도의 처리수를 얻을수 있는 폐수처리 방법이다.It is a wastewater treatment method that can obtain highly treated water even at high water load and organic matter load by keeping microorganism at high concentration in aeration tank.

본 발명의 중요한 용도로는 PVA를 사용하는 섬유, 접착제, 제지 및 기타 바인더용의 모든 PVA 함유 폐수에 응용이 가능하다.An important use of the invention is in all PVA containing wastewaters for fibers, adhesives, papermaking and other binders using PVA.
