Abstract

Abstract In this study, alkaline-H2O2 sludge disintegration was combined with anoxic-aerobic sequencing batch reactor (SBR). The carbon obtained by alkaline-H2O2 sludge disintegration was used in the denitrification process and sludge reduction was achieved in the SBR process. In the SBR process, a 9 % increase in nitrogen removal efficiency was achieved with the improvement in the denitrification process. A sludge reduction efficiency of 43 % was obtained in the SBR process with alkaline-H2O2 sludge disintegration. A synergistic effect was obtained in the combination of alkaline and H2O2 methods and the sludge reduction increased by 8 %. By combining sludge disintegration into the SBR process, it is possible to reduce the amount of sludge formed, which is an important environmental problem, and to provide carbon source for the denitrification process.
碱性- h2o2分解厌氧-好氧序批式反应器的脱氮及污泥减量
摘要本研究将碱性- h2o2污泥分解与厌氧-好氧序批式反应器(SBR)相结合。碱- h2o2污泥分解获得的碳用于反硝化工艺,并在SBR工艺中实现污泥减量。在SBR工艺中,随着反硝化工艺的改进,脱氮效率提高了9%。采用碱- h2o2分解SBR工艺,污泥减量率达43%。碱法与H2O2法联合使用,污泥减量提高8%。通过将污泥分解结合到SBR工艺中,可以减少污泥的形成量,这是一个重要的环境问题,并为反硝化过程提供碳源。
