Including paper content and ancillary information The <br><br>paper content includes four parts: abstract, introduction, materials and methods, and results and discussion. Each part is described separately. <br><br>First, the summary describes the study of a new method (SPDAF system) to improve the energy efficiency of sewage treatment, and uses data to show that fermentation is likely to produce short-term denitrification and easily biodegradable organic matter. <br>The second point, the introduction introduces the history of the development of wastewater treatment, and introduces the disadvantages of existing wastewater treatment methods, proposes a new method of wastewater treatment using a combined treatment process, and explores the advantageous bacteria.
