Description
本發明係有關於藉由將一種或多種高分子量的陽離子聚合物加入於薄膜生物反應器(簡稱為“MBR”)之活性污泥內，以增加供處理工業廢水之MBR之效能。
於MBR方法中，薄膜積垢一直是限制該方法之水力性能的重要問題。由於薄膜積垢，MBR之通量經常下降，且常需要更多薄膜來彌補通量損失。
近來，研究結果(Nagaoka等人，1996，1998；Lee等人，2002)顯示，薄膜積垢主要原因之一是生物聚合物，其包含在MBR之活性污泥中生長之生物體所分泌之多醣及蛋白質。
因此，已開發出使用在與活性污泥接觸時不與帶負電荷之薄膜反應的陽離子聚合物之方法(Collins和Salmen,2004；Collins等人，2005)。在此方法中，將各種聚合物直接加入MBR活性污泥中，與生物聚合物反應。所生成之微粒係由生物聚合物與合成的陽離子聚合物組成，不會積垢於薄膜表面。
儘管這些方法可以成功實施於大多數MBRs中，但已觀測到某些污泥，特別是工業污泥，當使用低分子量水溶性陽離子聚合物時，無法總是能充分地凝結。因此，需要一種更有效凝結工業污泥之方法。
本發明提供一種調節處理工業廢水之MBR中活性污泥之方法，其包括：加入有效量的一種或多種分子量大於約200,000道爾頓之陽離子聚合物於該MBR之活性污泥中。
本發明亦提供一種增進通過處理工業廢水之MBR中薄膜之通量之方法，其包括：加入有效量的一種或多種分子量大於約200,000道爾頓之陽離子聚合物於該MBR之活性污泥中。
本發明還提供一種減少於MBR中發泡之方法，其包括：加入有效量的一種或多種分子量大於約200,000道爾頓之陽離子聚合物於MBR之活性污泥中。
本發明還提供一種減少在該MBR之薄膜上積垢之方法，其包括：加入有效量的一種或多種分子量大於約200,000道爾頓之陽離子聚合物於該MBR之活性污泥中。
