| 中文摘要 |
| 目前国内人工快渗系统的研究主要集中在北方缺水、气候寒冷干燥地区，本文则针对土壤和气候条件特殊的三峡库区，试验研究CRI系统的构建及其处理性能，探索该技术在库区的适应性。结果表明：库区常见的灰棕紫泥土渗透系数较小，折算成水力负荷为0.1m3?(m2?d)-1，在该水力负荷下，湿干比为1d∶3d时，系统取得较好的处理效果。气候条件、土壤特性是影响湿干比的主要因素，1d∶3d的湿干比对库区是适宜的，表明CRI系统在三峡库区处理生活污水是可行的。 |
| 英文摘要 |
| The present domestic study on CRI mainly focuses on the cold and dry northern areas of water deficit. Aiming at the Three Gorges Reservoir Region featured with mild and wet climate and amethyst soil, this article makes a pilot study on the construction of CRI and its sewage disposal effects, and explores the applicability of CRI to the Three Gorges Reservoir Region. The findings show that the infiltration coefficient of amethyst soil is small----0.1m3?(m2?d)-1 when converted into hydraulic loading rate, and the CRI can obtain preferable sewage disposal effects with the mentioned hydraulic loading rate and 1d∶3d wet/dry (W/D) ratio. Climate and soil features are the main factors to W/D ratio and 1d∶3d W/D ratio is applicable to the region, which indicates CRI is feasible in sewage disposal in the Three-Gorges Reservoir Region. |
