摘　　要：采用天然丝瓜瓤作为反硝化固态碳源,在考察其释碳行为的基础上,进行静态反硝化实验,基于在除氮稳定期内,水中有机碳消耗量与硝酸盐氮去除量的比值保持恒定的假设,尝试建立耗碳和除氮的相关公式,并确定了室温条件下、进水NO_3^--N浓度为100 mg/L时,反硝化系统的碳氮比(C/N)为3.84,反映出植物纤维作为碳源所释放出的有机碳只有部分被用于反硝化反应.Natural luffa cellulose is used as carbon source for static solid-phase denitrification,the release of dissolvedorganic carbon as well as the C/N ratio are investigated. Assuming C/N ratio which means the ratio of consumptionof dissolved organic carbon to the removal of nitrate nitrogen remains constant during stable denitrification period,C/N ratio for the presented experimental system is evaluated as about 3.84,reflecting the fact that only part of thereleased organic carbon from natural cellulose is consumed during denitrification.
