Study on Energy Saving Methods for A2/O Process in Urban Wastewater Treatment Plants

Abstract:

Article Preview

The feasibility of saving energy for A2/O processes was studied in a wastewater treament plant located in beijing by means of field investigation and lab-scale experiment. The results indicate that there are two operable ways to save energy in A2/O processes. One is to control the DO strictly within 2~3 mg/L in aeration tank and to aviod over-aeration,the other is to shift the forepart of the aerated tank into anoxic tank,by which 17.1% of aration could be reduced and about 13.6% of TN removal rate could be increased.
