Micro-Polluted surface water Treatment by PAC-MBR Process

摘要

A kind of hybrid membrane process, which integrated powdered activated carbon (PAC) with mem- brane bioreactor (MBR), was designed for bench scale experiment for micro-polluted surface water treatment. Molecular weight analysis was used to evaluate the efficiency of each unit process and the integration of them. The result of analysis indicated that organic molecules in the treated water from PAC-MBR process were concen- trated on the section of below 1000, while PAC adsorption could enhance the removal efficiency of this section Due to the high percent of biodegradation recalcitrant organic matter with low molecular weight.
