Effects of Zinc on Anaerobic Fermentation of Sewage Sludge and Biogas Production
Original language description
Toxic metals can be present in municipal wastewaters sludge and may inhibit the process of anaerobic fermentation. According to literature zinc is one from toxic metals with the strongest inhibitory effect. Therefore, this article deals with effect of zinc on anaerobic fermentation of sewage sludge and biogas production. Inhibitory effect of zinc on anaerobic stabilization of sewage sludge was studied using batch anaerobic fermenters at temperature 42 oC +- 1 oC. Hydraulic retention time was 21 days. As toxic substance was used zinc chloride (ZnCl2) in three different amounts: 75, 312 and 625 mg/l which represent 12, 50 and 100 mg/l Zn, respectively. Biogas and methane yield after 21 days hydraulic retention time were used as comparative parameters of inhibitory effect of zinc. There were no significant differences between biogas yields from all tested concentrations of zinc and blank. There was only one significant difference between methane yields from tested concentrations of zinc and blank. The reduction of 6.3 +- 2.5% in the cumulative methane production can be observed after addition of 100 mg/l Zn (625 mg/l ZnCl2).
