Biological Phosphorus

The biological phosphorus (P) removal characteristics of a full-scale Unitank wastewater treatment plant (WWTP) were investigated by field survey, model analysis and sludge P content determination. In the Unitank WWTP, oxidation-reduction potential (ORP) reached the lowest value of -17 mV and the highest value of 130 mV at the end of anoxic/anaerobic stage and aerobic stage, respectively. The anaerobic P release process could be fitted by first-order kinetics with rate constant of 3.52 h-1, while the maximum aerobic P uptake rate was 3.31 mgP/(L•h). The measured sludge P content in the Shidongkou WWTP was 15.4±2.1 mgP/gSS, significantly lower than that in full-scale AAO WWTPs.

Hydrolysis acidification / pre-denitrification biological aerated filter was adopted in a domestic wastewater treatment plant. The effluent was accorded with a standard in the Integrated Wastewater Discharge Standard（GB18918-2002）, in which the effluent phosphorus was demanded below 0.5mg/L. Through analysis on the process biological phosphorus removal, biological method can be found to total phosphorus 1.5 mg/L. If you reach level to an emissions standards, phosphorus chemical experiment research, finally determined by strategy for the CN pool, point for adding potions FeCl3, dosing quantity for 35mg/L.
