基于模糊积分模型的抚仙湖北岸农村生活污水处理工艺效果评价

Technique Effect Evaluation for Treatment of Rural Domestic Sewage from the North Shore of Fuxian Lake Based on Fuzzy Integral Model

从经济、技术、环境3个方面筛选出3项准则层指标、9项指标层指标构建抚仙湖北岸农村生活污水处理工艺评价指标体系,通过层次分析法和熵权法相结合的主客观综合赋权法确定各个评价指标的权重,并用分层模糊积分模型对5种抚仙湖北岸农村生活污水处理工艺示范工程进行综合评价.研究表明,在示范工程所采用的5种农村生活污水处理工艺中,水解酸化-土壤净化槽强化脱氮工艺的处理效果为最佳.

In this paper,the technique evaluation index system for treatment of rural domestic sewage on north shore of Fuxian Lake was constructed through nine indicators of index layer and three indicators of criterion layer screened from social,economic and environ mental aspects.With integrated analytic hierarchy process and entropy method,the index weights were determined by considering the subjective and objective weighting methods.Based on hierarchical fuzzy integral model,a comprehensive evaluation was made on 5 kinds of domestic sewage treatment techniques used on north shore of Fuxian Lake.The study shows that the most effective one for treatment of rural domestic sewage of north shore of Fuxian Lake is the process of hydrolytic acidification-soil trench enhanced denitrification.
