本研究的主要目标是开发一种改进的膜生物反应器（MBR）系统，用于处理城市废水，同时增强氮（N）和磷（P）的生物去除，最终目标是优化这两个过程。本文将讨论 MBR 工艺在生物特性、运行性能和出水质量方面的实施和优化。该系统利用 MBR 中的缺氧吸磷和硝化反硝化作用。优化后，系统化学需氧量（COD）、NH3 –N 98.4%、TN 77.5%、P 去除率96.3%，出水生物需氧量、COD、NH3 –N、NO3 –N、NO2 –N、P 分别<3、3、0.4、5.8、0.050、0.18 mg/L，分别。
The main objective of the present study is to develop a modified membrane bioreactor (MBR) system for the treatment of municipal wastewater for the enhanced biological removal of nitrogen (N) and phosphorus (P) simultaneously with the ultimate goal of optimizing the two processes. The paper will address the implementation and optimization of the MBR process with respect to biological characteristics, operational performance, and effluent quality. The system utilizes anoxic P uptake and nitrification–denitrification in a MBR. Following optimization, the system achieved 99% chemical oxygen demand (COD), 98.4% NH3 –N , 77.5% TN, and 96.3% P removal producing effluent biological oxygen demand, COD, NH3 –N, NO3 –N, NO2 –N , and P of <3 , 3, 0.4, 5.8, 0.050, and 0.18 mg∕L , respectively.
