| 中文摘要: |
| 本文详细介绍了污水处理和回用相结合系统的野外试验，讨论了试验系统的设计、安装和资料收集，分析了试验过程中的水分平衡、污水灌溉过程中各种污染物的变化、积累和运动，为进一步优化利用此类系统提供了基础数据。研究结果表明，文中所提出的污水回用与污水处理相结合的系统，结合高强度的作物种植，可以处理高负荷的污水，排水中氮磷的浓度明显减少。 |
| 英文摘要: |
| A field experiment of the FILTER (filtration and irrigated cropping for land treatment and effluent reuse) technique was presented. The design of the system and the collection of the data are discussed in detail. The water balance and the variation and removal of contaminant in the process of irrigation are analyzed based on the experimental data. It is shown that the FILTER system is capable of handling high volumes application of effluent during the period of low cropping activity or high intensity rainfall. The concentration of nitrogen and phosphorous in the drainage water reduced dramatically. |
