Abstract

Large quantities of waste activated sludge can be produced with the growth of wastewater treatment plants. Anaerobic technology allows to co-digestion of nutrient-rich and high COD-containing wastes. The aim of this study was to investigate the effects of anaerobic disintegration of wastewater treatment plant sludge (WS) and vegetable wastes (VW). Batch experiments were performed under mesophilic conditions (37 ± 1°C) and eleven different VW / WS ratios and methane production potentials were evaluated by standard BMP test. The logistic model and modified Gompertz model were used to estimate methane yield and evaluate kinetic parameters. It was shown that the systems more stabled where VW and WS are fragmented together Modified Gompertz model (R2: 0.884-0.999) showed a better fit to the test results. As a result, according to the characterization of the sludge from the wastewater treatment plant, it is recommended that the sludge be dried and evaluated as well as the integrated management of the sewage sludge with organic wastes (vegetable waste).
