Abstract

The objective of this study was to investigate a small sewage treatment system. This system was developed to improve a nitrogen and phosphorus removal efficiency and generate less solid using upflow septic tank(UST) - aerobic filter(AF) system. The UST equipped with an aerobic filter, the filter was fed with both raw sewage and recycled effluent from the UST to induce the denitrification and solid reduction simultaneously. Overall removal efficiencies of COD and total nitrogen(TN) were above 96% and 73% at recycle ratio of 200%, respectively. Critical coagulant dose without the biochemical activity was found to be 40 mg/L. Removal efficiency of total phosphorus(TP) in influent was above 90% by chemical and biological reactions. Although the phosphorus concentration was low under the high alkalinity in raw sewage, the pH value was unchanged by the coagulant dose.
