Abstract:
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, We make 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--0.1m(3) x (m2 x 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.
