| 摘 要： | 在大量分组试验(中试)数据的基础上，剖析了强化厌氧塘、兼性人工湿地、强化好氧塘和水生植物根系塘的最佳工艺参数以及整体系统的组合性能，探讨了氮和磷元素在各单元塘以及系统中的迁移、降解规律。实验表明，在该组合形式的系统中，各级单元塘之间具有较强的互助和互补性，前面单元为后续单元提供了较好的前处理，使得后续单元能够较充分地发挥处理功效，同时由于结合了在厌氧、兼氧以及好氧状态下微生物、高等绿色植物根系、土壤(砂层)的同化、分解、截流、吸收、吸附和过滤等处理机制，使得该系统较传统稳定塘工艺具有更高的氮和磷的去除效率。

| Abstract: | On the basis of plenty of data from pilot\|scale batch experiments, the optimal process parameters for intensified anaerobic pond, facultative wetland, intensified aerobic pond and root\|zone pond as well as the combined properties of the integrated system were investigated. The transport and degradation rules of nitrogen and phosphorus in both the cell ponds and the whole system were also explored. The experiments showed that in the combined system, there are great cooperative and complementary mechanisms among the cell ponds. One cell provides the pretreatment for the subsequent cell, which makes the subsequent cell play full roles. Simultaneously, duo to combination of all the treatment mechanisms such as assimilation, decomposition, interception, absorption, adsorption and filtration of microbes, wetland roots and soil under the anaerobic, facultative and aerobic conditions, the system has higher nitrogen and phosphorus removal efficiencies than normal pond systems. |
