Effect of DEHP on SCFA Production by Anaerobic Fermentation of Waste Activated Sludge

Figure 1

The effect of DEHP on the total SCFA yield and the ratio of each SCFA under optimal conditions of anaerobic fermentation sludge. (a) SCFA yield without alkali pretreatment; (b) SCFA yield with alkaline pretreatment; and (c) the ratio of each SCFA on 5 days without alkali pretreatment; (d) The ratio of each SCFA on 5 days with alkaline pretreatment. Error bars represent standard deviations of triplicate tests.
