A new flat-sheet submerged membrane photoreactor (FSMPR) for the removal of humic acid in water

摘要

The study focuses on the degradation humic acid (HA) by a hybrid system combining a flat-sheet submerged membrane module and a photocatalysis reactor (FSMPR). The influences of UV irradiation intensity, titanium dioxide (TiO_2) and initial humic acid concentration, pH, H_2O_2 dosage were investigated in batch kinetic tests. and the relevant dynamic analysis was carried out. The transmembrane pressure (TMP) with time under the range of constant flux operation(20-40L/m~2h) does not increase obviously. It was also found that aeration backflush availably reduced TMP of the FSMPR. Therefore, the FSMPR can be potentially applied in drinking water treatment.
