| 摘 要： | 结合日处理水量 105m3的东营生态塘 2002 年运行情况,探讨了塘中氮的去除机理与磷的去除途径.结果表明,氮通过沉淀、硝化反硝化、植物吸收以及氨的挥发而去除;磷通过生物吸收、沉淀方式去除.对各种去除方式的定量计算结果表明,硝化反硝化是塘中氨氮去除的主要途径;沉淀是磷去除的主要方式.

| Abstract: | The Dongying eco-pond which could treat 105m3 of water daily was put into operation. Combined with the operational state of the pond in the year 2002, the nitrogen and phosphorus removal at various states in the pond was explored. Nitrogen was removed through precipitation, nitrification denitrification, plant absorption and ammonium volatilization. Phosphorus was removed through plant absorption and precipitation types. The results of quantification calculation of various types of removal showed that the main way of NH4 -N removal in Dongying eoc-ponds was nitrification denitrification. Precipitation is the main type of phosphorus removal. |
