Analysis on Phosphorus Removal from Domestic Wastewater Treatment Plant by Biological Aerated Filter

摘要

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 (GB 18918-2002),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.
