【 摘 要 】

Problem statement: A constructed wetland to treat wastewater from farm house has beenbuilt in Padjadjaran University farming research station in Jatinangor, Indonesia, in July 2009.Approach: Water samples from both influent and effluent were taken every two weeks and analysedfor COD, BOD₅, NO₃-N, NO₂-N, NH₄-N, total-N, PO₄-P, total coliform bacteria, pH, O₂ and settleablesolids. Results: The objective of this study was to install one constructed wetland with a vertical flowsystem to treat sewage from farm house by using an aquatic macrophyte (Phragmites karka). Theaverage treatment efficiencies during the period from August 2009 to January 2010 for BOD₅, COD,NH₄-N, total- N, PO₄-P and total coliform bacteria were 76,03, 78,89, 88,18, 71,70, 91,06 and 99,45%respectively. The average concentration in effluent from period of August to January for BOD₅ was21.87 mg L^-1, COD (57.66 mg L^-1), NH₄-N (0.82 mg L^-1), NO3-N (1,36 mg L^-1), total-N (2.68 mg L^-1),PO₄-P (0.07 mg L^-1) and total coliform bacteria (4880 MPN/100 ml). Conclusion/Recommendations:The overall results show that all effluent concentration from constructed wetlands except BOD₅ werestill low and fall considerably short of Indonesian effluent standards for irrigation water. These resultswere very promising to be used in treating wastewater from agricultural industry and produce cleanwater which then can still be used for other purposes such as irrigation water, fisheries and othernecessities.
