“…At present, biological nitrogen and phosphorus removal is the most economical and effective means to control water pollution [1]. To effectively remove nitrogen and phosphorus and adapt to various water quality, researchers have designed a variety of sewage biological nitrogen and phosphorus removal processes, and the micro-pressure swirl reactor (MPR) was one of them.…”

To explore the suitable external carbon sources for Micro-pressure swirl Reactor (MPR), the experiment was run in parallel through two MPRs, using starch and glucose as carbon sources respectively. Research indicated that under the experimental operating conditions, using starch as the carbon source could more effectively promote the biological denitrification of the MPR system. Due to the structural characteristics of MPR and the slow degradation of starch, the demand for carbon source for denitrification was ensured during the operation cycle, so that the system obtained a better denitrification effect. The test results provided reference for the selection of the external carbon source of the MPR process.
