Effects of copper on operating parameters during anaerobic stabilization of sewage sludge
Original language description
The presence of heavy metals have negative effect on sewage sludge anaerobic stabilization mainly on biogas production and quality. The objective of this study was to monitor pH, volatile acids (acetic, propionic, butyric and valeric) content in sludge and biogas production and quality during the anaerobic stabilization of sewage sludge in laboratory conditions (38 oC +- 0.2 oC, hydraulic retention time 20 days), and to observe the effect of copper addition on the above parameters. Hypothesis which predicted the changes of monitored parameters mainly biogas quantity and quality, volatile acid content and pH after copper addition, was partly confirmed. There were no significant differences in biogas and methane production after addition of 600 and 800 mg Cu2+/l. On the other hand, significant differences can be seen on pH, acetic and propionic content in sludge and hydrogen content in biogas. These parameters were significantly affected by different concentrations of copper.
