摘　　要：对现有农村污水治理方式进行了总结和效果评价。提出了适合宁波地区农村污水治理的4类模式,分别是污废合流的集中模式、分散模式,污废分流的分散模式、过渡模式。分析了模式选择的影响因素,分别是人口规模、集聚模式、地形、地质条件、功能区域,并对目标村庄进行了相应分类,建立数学模型探讨了集中与分散模式的经济距离以及集中模式下户均投资的控制距离,最后根据研究成果对首批实施的14个行政村25个自然村的生活污水治理模式进行了选择。The present situation of rural domestic sewage treatment was summarized and evaluated. The four treatment models suitable in Ningbo district to treat rural domestic sewage were put forward, including centralized treatment of mixed sewagemanure, decentralized treatment of mixed sewage-manure, decentralized treatment of sewage and manure separately and centralized treatment of sewage and decentralized treatment of manure. The factors to affect selecting the treatment model were found out as population, assembling pattern, terrain, geological conditions and function areas. The subject villages were classified and corresponding mathematical models were established by which the economical distances of centralized and decentralized treatment models as well as the control distance of household average investment of the centralized model were discussed. Finally, according to the research result the treatment models for 14 administrative villages containing 25 natural villages were selected as the first group.
