Abstract: The aim of the study on a landfill leachate treatment is to determine the accumulation of SMP in
membrane bioreactor ( MBR ) and its influence on the slutdge activity and the membrane filterability of the
mixed sludge liquor. The results indicated that the concentration of anic matter held in MBR increased
from 226. 4 mg / L to 504. 0 mg / L with the biodegradability of inlet landf
