Abstract

This study was carried out to obtain Kinetic constant of Moving Media Complete Mixing Activated Sludge (MMCMAS) for the wastewater treatment. A laboratory MMCMAS reactor was operated at the organic loading rate of 2.5g$BOD_{5}$/$m^{2}$ /d~48g$BOD_{5}$/$m^{2}$/d kinetic constant of MMCMAS reactor was estimated as follows:

하수와 우유를 섞은 합성폐수를 처리하기 위해 회전매체를 이용한 완전혼합활성슬러지 공법의 kinetic constant 값을 산정한 결과, $K_{m}$(유기물제거속도) 값은 저부하의 경우는 3.75~8/hr, 고부하인 경우는 8.57~12.5/hr이며, $K_{e}$값은 저부하인 경우 0.007~0.03/hr, 고부하인 경우는 0.09/hr로, $K_{s}$(내호흡계수) 값은 저부하인 경우 1.73~3.68/hr, 고부하인 경우는 3.84~5.75/hr로 나타났으며, Y 값은 0.46gVSS/g$BOD_{5}$로 산정 되었다.
