MBR工艺在农村生活污水处理中的应用

Application of MBRProcess in Rural Domestic SewageTreatment

近年来,MBR工艺在农村生活污水处理中逐步得到应用,其采用较多的膜组件类型为平板膜和中空纤维膜。以国内采用平板膜和中空纤维膜处理农村生活污水的项目为基础,对比分析了平板膜和中空纤维膜的处理效果、预处理要求、膜通量及产水效率、清洗方式、工艺成本等相关参数,并分析了平板膜和中空纤维膜用于农村生活污水处理的优缺点,分析结果对MBR工艺在农村生活污水处理中的应用具有一定的参考价值。

In recent years,the membrane bio-reactor(MBR)process has gradually been applied in rural domestic sewage treatment.The commonly used membrane component types are flat membrane and hollow fiber membrane.Based on the project of treating rural domestic sewage by flat membrane and hollow fiber membrane,a comparative analysis was conducted on the treatment effect,pre-treatment requirements,membrane flux and water production efficiency,cleaning methods,process costs and other related parameters by flat membrane and hollow fiber membrane.The advantages and disadvantages were also analyzed.The analysis results have certain reference value for the application of MBR process in rural domestic sewage treatment.
