摘要：
Tai Lake, as an important water source in the southeast of China, and has been undergoing serious pollution. In order to meet more stringent standards for wastewater treatment and reuse in the limited area, it is necessary to upgrade existing WWTPs. Due to high effluent quality and low footprint, MBR has been widely utilized and considered as an alternative for WWTP upgrading. The main purpose of this study was to assess the removal efficiency of chemical oxygen demand (COD), nitrogen and phosphorus in three WWTPs retrofitted by full scale membrane system in Tai Lake basin. The combination of conventional biochemical and MBR system showed excellent removal effect of target contaminants. The effluent quality met the first level A standard specified in the Discharge Standard of Pollutants for Municipal WWTPs with COD <50 mg/L, mixed liquor suspended solids (MLSS) < 10 mg/L, NH4+-N < 5 mg/L, total nitrogen (TN) < 15 mg/L, and total phosphorus (TP) < 1 mg/L). It proves that MBR system is efficient for WWTP upgrading in Tai Lake basin. In addition, this study attempted to summarize these three WWTP cases on the basis of operational results, technical and economical parameters, and provide suggestion for an optimal configuration and design of a WWTP with MBR technology.
