概要

• 論文の詳細を見る

• Poor sludge settling was observed occasionally during the treatment of effluent from acrylonitrile and acrylates manufacturing plants using an extended aeration activated sludge process. Sludge settled excellently when suspended in water or a filtrate obtained by passing aeration tank supernatant through granular activated charcoal (GAC) column. A biofactor consisting of 52% lipid, 10% protein, and 11% carbohydrate was isolated from the supernatant obtained after removal of suspended solids from aeration tank wastewater. Addition of biofactor in water or GAC filtrate adversely affected the sludge settling.
