【摘要】 以库区农村为研究对象,运用层次分析法,对库区农村生活污水处理技术进行分析优选,筛选出最优生活污水处理技术。在层次分析法的分析筛选中,以农村生活污水处理常用的五种技术设为方案层;把实现农村生活污水达标排放作为目标层;把五种方案的技术可行性、经济可行性、环境可行性、政策可行性作为的目标评价层,建立层次模型,再构造判断矩阵,根据矩阵中各因素标度值来计算其比重,最后通过层次总排序表计算出5种水处理技术的优先顺序,为库区农村生活污水处理技术的选择提供理论依据。更多还原

【Abstract】 As the research object to countryside in three gorges reservoir,use Analytical Hierarchy Process to optimize rural domestic sewage treatment technology in three gorges reservoir,then choose the best one.In the application,taking five rural domestic sewage treatment technology as project level,rural domestic sewage discharge standards as target layer,the feasibility of five programs in technology,economy,environment and policy as objective evaluation layer,establish hierarchical model and construct judgment matrix,calculate the proportion of factors according to their scale value.Calculate their priority in level sort table.Provide theoretical basis for the choice of rural domestic sewage treatment technology in three gorges reservoir.更多还原
