高负荷曝气或变型曝气 部分污水厂只需要部分处理,因此产生了高 负荷曝气法。 曝气池中的MLS,约为300~500mg/L,曝 气肘间比较短,约为2~3h,处理效率仅约65% 左右,有别于传统的活性污泥法,故常称变型 (c) High-rate aeration cormie Irem High rate aeration is a prooess modification in which low MLsS concentrations are combined with high wolumetric BOD loadings. The role system is daraderized by short T, high sludge recycle ratio, high F/M looding, and relatively low MLSS concentrotion High-rate systems produce a lesser event quality, in terms of BOd and TSS concentration ed to of the high loading used, more care must be laken to keep a stabl operation.Adequate mixing and aeration ore veryimportant9 部分污水厂只需要部分处理，因此产生了高 负荷曝气法。 曝气池中的MLSS，约为300～500mg/L，曝 气时间比较短，约为2～3h，处理效率仅约65％ 左右，有别于传统的活性污泥法，故常称变型 曝气。 高负荷曝气或变型曝气
