ELECTROCHEMICAL OXIDATION OF LEACHATE PRETREATED IN AN UPFLOW AN AEROBIC SLUDGE BLANKET REACTOR

摘要

This study was conducted to develop a two-stage process for the treatment of Hong Kong leachate. The leachate, containing 4750 mg l~-1 of chemical oxygen demand (COD) and 1310 mg l~-1 of ammoniacal nitrogen (NH_3-N), was first treated in a UASB (upflow anaerobic sludge blanket) reactor at 37 deg. C. The process removed on average 66.1/100 days of Hydraulic retention time (HRT), corresponding to an organic loading rate of 0.78 g-COD (1-day)~-1.
