Study on the Effects of Technological Factors of Shortcut Nitrification-Denitrification Simultaneous Phosphorus Removal

Abstract:

Through the SBR Shortcut Nitrification-Denitrification Simultaneous Phosphorus Removal treatment of comprehensive wastewater in beer production , In order to achieve the removal of COD,NH4+ ,TP and the accumulation of NO2 --N stability , The research on the influence factors of the process. The results showed that: The stable operation of the process is made up of influent COD concentration, PH, DO, together with the factors such as temperature and MLSS, which control the DO value of low (< 0.5 mg/L) is to achieve one of the key factors of NO2--N accumulation. Too low or too high influent PH value, COD concentration will influence the normal running of the process. Temperature and MLSS affect ammonia oxidation process and the reaction rate of denitrification process, but not the determinants of the system stable operation. When DO is 0. 3 ~ 0.5 mg/L, influent COD concentration below 1100 mg/L, pH value of 7. 2 ~ 8. 4, temperature in 12 ~ 25 °C, it can obtain stable NO2--N accumulation.
