Domestic sewage treatment in rural areas is an important part to improve rural living environment and promote implementation of rural revitalization strategy. Aiming at the current key bottleneck problem such as blindness and lack of scientificity existed in selection of rural domestic sewage treatment mode (i.e., centralized, relatively centralized and decentralized), a theory of dispersion degree of rural resident (Dr) was proposed for the first time. The theory constructed a Drcalculation model by using some parameters such as the resident population dispersion distance and the maximum population density, and it established a Dr-based method for choosing the treatment mode of rural domestic sewage and defining its application range by using administrative region as a hierarchical unit. Meanwhile, the Drof S town in Chongming District, Shanghai, at town level, village level and group level were calculated to be 3.63, 2.00-5.13 and 7.92, respectively. Combined with the experience value of centralized treatment Drand engineering analysis, it was eventually determined that S town was not suitable to adopt the centralized domestic sewage treatment mode in the whole town, while relatively centralized or decentralized treatment should be adopted at the village level or group level.
