Zoogloea

Filamentous bacteria exists in every activated sludge system,the problem of sludge bulking will happen only when filamentous bacteria grows over than zoogloea ,the obove-mentioned problem will not occur when filamentous bacteria and zoogloea equally grow.

任何活性污泥系统中都存在着丝状菌,在丝状菌与菌胶团细菌平衡生长时,不会发生膨胀污泥问题,只有当丝状菌生长超过菌胶团细菌时,就会出现污泥膨胀问题。

During the process of cultivating activated sludge by using domestic sewage with direct aerating way,branched zoogloea appeared,whose branched-body stretched out from activated sludge floc and extended and grew.

通过显微分析,表明生枝状菌胶团对活性污泥絮凝沉降具有促进作用;其生长点在枝状体的顶端,动胶菌呈"纵向连接",因此形成枝状菌胶团;该菌胶团的形成需要较长的泥龄:约25 d,其出现时曝气池内溶解氧维持较高水平:3。
