Abstract

Several physical, chemical, biological methods and combination of them are used for domestic wastewater nitrogen and phosphrous removal. In this study, subsurface horizontal constructed wetland with length of 13-6 m, width of 10 m and depth of 0.55 m with Phargmites australis is used. Soil porosity was 40 percent. The system irrigated with domestic wastewater. The wastewater COD, TN, TKN and PO4 concentration was 300, 45-57 and 45-92 mg /l respectively. Hydraulic loading increased from 5 cm / day to 7.2 cm /d while detention time decreased from 4.2 days to 3 days. Removal percent of COD, TN, TKN and PO4 = at hydraulic loading equal to 5 cm / d and detention time of 4.2 days was 90, 83, 94 and 92 percent respectively. The study also indicates that removal percent of COD / TN / TKN and PO4 = at loading of 7.2 cm/day was 93, 8, 86 and 73 respectively.
