中空纤维MBR与平板MBR比较 序 比较点 平板MBR 中空纤维MBR 号 Comparison (Flat Plate MBR) (Hollow fiber MBR) No. 膜材料 主要是PVDF、PES等 主要是PVDF，部分PS、PE、PP 1 (Membrane Material) (mainly PVDF, PES) (mainly PVDF, partial PS, PE, PP) 应用于污水处理及回用的MBR膜，要求材质必须有强抗氧化性和抗污染性，因此PVDF比其它材质（如PE、PP）超强的抗氧化性和抗污染性，决定了PVDF材质是 分析 国际上MBR膜 (Description) MBR membrane when used in wastewater treatment and resue, whcih require the materials should have stong anti-oxidation and anti- pollution, therefore PVDF is a good material than other materials such as PE PP, and widely used internationally. 2 前处理要求 中格栅2～3mm 超细格栅（0.8～1.5mm） (Pretreatment requirement) (middle size grid 2~3mm) (Ultra-fine grid 0.8～1.5mm） 中空纤维有被毛发缠绕断丝的风险，大型MBR选用的超细格栅间隙越来越小，超细格栅预 平板MBR强度高，对预处理要求相对较宽。 处理的作用越来越重要。 分析 Flat plate MBR, high strength, relatively wide Hollow fiber MBR, the risk of being broken with wrapped hair. Ultra-fine (Description) pretreatment requirement grid for large MBR, the gap getting smaller and smaller, increasingly
