Abstract

For the disposal of sewage sludge, supercritical water treatment is a potential approach. Systematically investigated were the effects of temperature and oxidation coefficient on the end products of sewage sludge treatment in supercritical water. The findings demonstrate that increasing OC or temperature had a clear positive impact on CO 2 output. Oxidant assisted in converting molecules containing N into N 2. H2 yield was boosted by oxidant in small doses, but decreased in large doses.
