摘 要
随着城市化进程的加快,市政污水处理面临日益严峻的挑战,传统处理工艺难以满足日益严格的排放标准和水资源回用需求。本研究聚焦高效膜生物反应器(MBR)在市政污水处理中的应用,旨在探索其在提高出水水质、减少占地面积及实现资源回收方面的潜力。通过构建中试规模MBR系统,采用活性污泥法与超滤膜组件耦合技术,对实际市政污水进行为期一年的连续运行实验,考察不同运行参数对系统性能的影响。结果表明,在优化条件下,MBR系统对COD、氨氮和总磷的去除率分别达到95%、98%和90%以上,出水水质稳定优于一级A排放标准。特别地,本研究创新性地引入了智能控制算法,实现了膜污染的有效预防和能耗的显著降低,较传统MBR系统节能约20%,同时延长了膜组件使用寿命。

Abstract
With the acceleration of the urbanization process, the municipal sewage treatment is facing increasingly severe challenges, and the traditional treatment process is difficult to meet the increasingly stringent discharge standards and water resources reuse demand. This study focused on the application of high efficiency membrane bioreactor (MBR) in municipal sewage treatment, aiming to explore its potential in improving effluent quality, reducing footprint, and realizing resource recovery. By constructing a pilot-scale MBR system, using the coupling technology of activated sludge method and ultrafiltration membrane components, a one-year continuous operation experiment was conducted to investigate the influence of different operating parameters on the system performance. The results show that under the optimized conditions, the removal rate of COD, ammonia nitrogen and total phosphorus can reach 95%, 98% and 90%, respectively, and the effluent water quality is stable and better than the level A discharge standard. In particular, this study innovatively introduced the intelligent control algorithm, which realized the effective prevention of membrane pollution and the significant reduction of energy consumption, saving about 20% energy compared with the traditional MBR system, and extending the service life of membrane components.
