| 摘 要： | 以菱角为试材,研究其对富营养化水体的净化效果。研究结果表明,菱角对富营养水体中总氮(TN)、总磷(TP)、化学需氧量(COD)的去除率分别为53.51%、33.86%、67.52%,水中溶氧量(DO)从5.23 mg/L回升至15.42 mg/L,透明度由18 cm增至48 cm。由此可见,菱角能够有效改善富营养化水体的水质,适合推广应用。

| Abstract: | Using Trapa bicoruis L. F. as material, its purification effects on eutrophic water were investigated. The results showed that the removal rates of total nitrogen （TN）, total phosphorus （TP） and chemical oxygen demand （COD） were 53.51%, 33.86% and 67.52% with T. bicornis L. F., and the dissolved oxygen （DO） raised from 5.23 mg/L to 15.42 mg/L and the transparency increased from 18 cm to 48 cm. It was proved that T. bicornis L. F. had significant effects on improving the quality of eutrophic water. |
