| Abstract: | Two process models of two-stage sequencing batch reactor with series operation for biological phosphorus and nitrogen removal are presented based on analysis of the defects of single-stage activated sludge method. Through rational control of operation processes, it is expected to solve the problems encountered in single-stage process, such as carbon source, SRT, nitrate in anaerobic zone, organic compounds resistant nitrification, longer time aeration, and higher power consumption, etc. It will make microbe with different functions to grow in respectively beneficial conditions. Consequently, the effect and stability for the system can be greatly improved. The process of model 1 is suitable for treating wastewater with higher BOD 5/TP, whereas that of model 2 is not sensitive to BOD 5/TP. |
