MBR工艺处理污水效果及影响因素分析

Analysis on Treatment Effect and Influence Factors of MBR Process

通过对太湖流域某城市污水处理厂的MBR系统实际运行数据进行分析,研究了影响该系统运行效果的三个重要因素:污泥浓度(MLSS)、温度与进水有机物浓度。研究结果表明,较高的污泥浓度使系统具有较强的耐冲击负荷能力并可以减小低温对处理系统的影响,进水有机物浓度与总氮和总磷的去除具有较强的相关性。

Based on the analysis of practical operation data of MBR system in a municipal wastewater treatment plant in Taihu Lake basin, three important factors to influence the effect of the system, such as MLSS, temperature and the concentration of organic compounds in the influent were stud- ied. The results showed that high sludge concentration enabled the whole system to have strong resistance to shock loading and could reduce the impact of low temperature on treatment system. The concentration of organic compounds in the influent had a strong correlation with total nitrogen and total phosphorus re- moval.
