生物膜法和活性污泥法有哪些異同之處?

文章出處:本站 人氣:713發表時間2022-09-03

生物膜法和活性污泥法是以生化處理的不同反應器形式,從外觀上看主要區別在于前者的微生物不需要填料載體,生物污泥是懸浮的,而后者的微生物是固定在填料上的,然而它們處理廢水、凈化水質的機理是一樣的。另外,二者的生物污泥都是好氧活性污泥,而且污泥的組成也具有一定的相似性。此外,生物膜法中的微生物,由于是固定在填料上的,可以形成比較穩定的生態系統,其生活能量和消耗能量不象活性污泥法中的微生物那樣大,因此生物膜法的剩余污泥比活性污泥法要少。上海信誼百路達藥業有限公司的接觸氧化池采用生物膜法,而SBR生化池采用活性污泥法。
