Abstract :
The behavior of CODMn and NH4 +-N removal under an integrated and submerged MBR was investigated, the plate membrane shows better stability in filtration during the long period of operation, and the removal efficiency of COD reached as much as 80%, but that of NH4 +-N was below 50%, This findings may be largely responsible for the relative lower pH value of the sludge, which could severely hinder the nitrification ability of nitrifying bacteria. Consequently, out of pH control, the reactor maintains its pH value at about 5.4.
