基于生物膜的市政污水处理与回用技术研究

Biofilm-based Municipal Wastewater Treatment and Reuse Technology

市政污水的有效处理与回用效果至关重要。以降低水污染程度、创建绿色用水环境,提出基于生物膜的市政污水处理与回用技术。首先,分析中国近两年的市政污水排放情况,总结市政污水中负荷较重的污染物,并深入探讨生物膜的实际应用场景和使用流程。然后以实验的形式,从常规生物膜反应器的作用原理和模拟市政污水入手,分别从膜通量、跨膜压差、污染物去除率和碳、磷回收率四个方面分析生物膜对市政污水的处理与回用性能。研究结果表明,生物膜在市政污水处理与回用方面具有较高的应用价值。

The effective treatment and reuse effect of municipal sewage is very important.In order to reduce the degree of water pollution and create a green water environment,municipal wastewater treatment and reuse technology based on biofilm is proposed.First of all,the study analyzes the discharge of municipal sewage in China in the past two years,summarizes the pollutants with heavy load in municipal sewage,and deeply explores the actual application scenario and use process of biofilm.Based on the principle of conventional biofilm reactor and the simulation of municipal wastewater,the treatment and reuse performance of biofilm for municipal wastewater is analyzed from four aspects:membrane flux,transmembrane pressure difference,pollutant removal rate and carbon and phosphorus recovery rate.The results show that biofilm has high application value in municipal wastewater treatment and reuse.
