Study on the synergistic anaerobic fermentation technology of hydrothermal pretreatment of gas floating sludge and kitchen waste
In this study,hydrothermal technology was used to pretreatment the air floating sludge,it was found that the SCOD content,CODdissolution rate and ammonia nitrogen content increased with the pretreatment temperature after pretreatment of 160 ℃,180℃,200℃,and 220℃.Secondly,the synergistic anaerobic gas production of hydrothermal products and kitchen waste was investigated,Through sequential batch test,it was found that the cumulative gas production and cumulative methane production at 180 ℃ were the highest values in each experimental group,527.6 mL g-1VS and 290.0 mL g-1VS,respectively,which were about 25.4％and 23.6％higher than the untreated group.
