Abstract

Abstract

The anaerobic biodegradability and methane yield of the low organic municipal sludge could be significantly improved on anaerobic co-digestion, by combing banana straw with high temperature thermal hydrolysis pretreatment (HTHP). In the combining system of anaerobic co-digestion and HTHP, the methane yield of municipal sludge, banana straw and their mixture were 388, 372, 537mL/gVS, respectively, which showed the significant synergistic effect. In their own optimal pretreatment condition of sludge, banana straw and their mixture, the T80 was 12, 19, 17 days, respectively, which could be represented as hydraulic retention time of anaerobic digestion; SCOD dissolution ratio was respectively 14.4, 2.8, and 5.9 times of those before pretreatment; SCOD removal rate was 93.7%, 89.8% and 94.5% after anaerobic digestion, and the removal rate of VS was 48.4%, 48.8% and 59.2%, respectively. The concentration of soluble protein, VFA and soluble polysaccharide were increased significantly, which was 14.5, 5.1 and 8.2 times of that before HTTP, and the removal rate was 94.4%, 94.9% and 95.2% in the subsequent anaerobic digestion stage, which was slightly higher than single treatment.
