第三点，材料与方法说明所需的废水来源和污泥种子，以及实验操作步骤和涉及

The third point is that the materials and methods explain the source of wastewater and sludge seeds required, as well as the experimental operation steps and the calculation methods and analysis methods involved. <br>Finally, the results and discussion are based on the data analysis of the material change trend in the experiment, and the advantages are obtained from the analysis. Trends obtained from the control variables at different stages of the flora and the system.

Third, the material and method describe the required wastewater source and sludge seeds, as well as the experimental operation steps and related calculation methods and analysis methods<br>Finally, the results and discussion are based on the trend of material change in data analysis experiments, and analyze the trend of controlling variables at different stages of the dominant bacteria and system.
