Abstract

Abstract

MBR had become one of the most effective technologies in the field of municipal wastewater advanced treatment due to its obvious advantages, but its high operating cost limited its promotion and application. Taking a large MBR sewage treatment project of a reclaimed water plant in North China for example, membrane pollution and operation energy consumption were explored by adopting new membrane device and reasonable process design. The following conclusions were drawn by analyzing the actual operation data as follows:1) although the concentration of the influent pollutants fluctuated greatly, the effluent quality was stable and water quality indices were superior than the class B requirements specified in Water Pollutants for Municipal Wastewater Treatment Plants(DB 11/890-2012); 2) the membrane products in applied in the MBR system was PVDF material and prepared by TIPS method. The membrane featured high strength and high filling density, reaching 895 m²/m³; 3) advanced pre-treatment system and high intensity pulse aeration system were adopted in the MBR to effectively reduce the membrane fouling, and then the aeration cost was reduced by about 25%.
