Abstract
The purpose of this study was to investigate the removed of nitrogen, phosphorus and organic matter from synthetic wastewater using the soil column. Soil, wasted oyster shell and denitrifying activated sludge were used as a supporting media of the soil column.
In the batch experiment, the addition of 20% of oyster shell to the soil accelerated nitrification in the soil column.
The influent ammonia nitrogen was mostly convert to nitrate nitrogen in soil column and little ammonia nitrogen was found in the effluent.
The inoculation of denitrifying activated sludge on soil column was also effective in accelerating denitrification.
When methanol and glucose were added as an electron donor on nitrate reduction the methanol was a more efficient electron donor then glucose.
The influent COD/NO3-N ratio of 4.4 is require to remove the nitrogen biologically. The removal rate of 86.3% achived in the soil column and the effluent T-N was about 10mg/L.
In the continuous experiment, the simultaneous removal of ammonia nitrogen and organic matter occurred in organic matter decomposition reactor.
The T-N removal rate of 87.4% achived at HRT of 36 hours in denitrification reactor.
