基于熵权法-模糊综合评价模型的生活污水低碳处理模式评价
Evaluation of low-carbon treatment modes for domestic wastewater based on an entropy weight-fuzzy comprehensive evaluation model
摘要
Abstract
Towards low-carbon treatment mode optimization for rural domestic wastewater and improvement of the evaluation system for wastewater treatment projects,an entropy weight-fuzzy comprehensive evaluation model was proposed in this study.The indicator system of this model covers six dimensions:technical efficiency,economic benefits,social performance,environmental impact,carbon reduction efficiency,and resource recovery efficiency.Using the membership degree theory of fuzzy mathematics,the evaluation criteria for the indicators were established.Guided by the domestic wastewater treatment needs of Shenyu Village,the constructed model was applied to select the optimal process:enhanced septic tank-anaerobic tank-passive gray water purification tank.A wastewater treatment facility was built and operated stably.The entropy weight-fuzzy comprehensive evaluation model was used to comprehensively assess Shenyu Village's wastewater treatment project.The results showed that this process performs well in technical,social,and ecological efficiency,with an overall comprehensive evaluation grade of"excellent".However,the membership degree was only 0.41.Further analysis suggested that utilizing treated gray water for farmland irrigation,landscape crop watering,and expanding agricultural land use for blackwater treatment could enhance rural domestic wastewater utilization and reduce carbon emissions.This study provides a decision-making methodology for selecting low-carbon treatment modes,upgrading processes,and promoting resource utilization in rural domestic wastewater management.关键词
