A Process for Treatment of Wastewater Using Intermittently Aerated Membrane Bioreactor

摘要

In the membrane activated sludge method using a hollow fiber membrane according to the present invention, by performing an anoxic stage and an aeration stage alternately in an appropriate time program in the same single reactor, and limiting the membrane filtration only at the aeration stage, the nitrogen removal efficiency is dramatically increased and the membrane Provided is a sewage treatment method capable of effectively suppressing blockage. In this way, a sewage treatment method is provided that can further achieve high efficiency of nitrogen removal without installing a separate facility while maximizing the advantages of the existing membrane activated sludge method.
