摘要:- 農(nóng)村生活污水治理是改善農(nóng)村人居環(huán)境、推進鄉(xiāng)村振興戰(zhàn)略實施的重要環(huán)節(jié)。針對目前農(nóng)村生活污水處理模式（集中式、相對集中式、分散式）選擇時存在盲目性、缺乏科學(xué)性等關(guān)鍵瓶頸問題，首次提出了農(nóng)村人口居住分散度（Dr）理論，利用人口居住離散距離、區(qū)域最大人口密度等參數(shù)建立了人口分散度Dr計算模型，并以行政區(qū)域為分級單元，確立了基于人口分散度的農(nóng)村生活污水處理模式選擇方法和適用范圍。同時，進一步以上海崇明區(qū)S鎮(zhèn)為應(yīng)用案例，經(jīng)計算S鎮(zhèn)鄉(xiāng)鎮(zhèn)級、村級和村民小隊級Dr分別為3.63、2.00~5.13和7.92，結(jié)合集中處理Dr經(jīng)驗值和工程分析，最終確定S鎮(zhèn)不宜采用全鎮(zhèn)集中式生活污水處理模式，應(yīng)以村或村民小隊為單元選擇相對集中式或分散式處理。
Abstract:- 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 Dr calculation 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 Dr of 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 Dr and 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.
