| 摘 要： | 构建污水再生利用工程评价指标体系并对其运行状况进行综合评价。根据集中式和分散式污水再生利用工程的不同特征,在分析其主要影响因素的基础上,分别构建了由水量、水质、技术、经济、管理5个方面量度,13个单项指标组成的污水再生利用工程运行状况评价指标体系,采用BP神经网络综合评价法,选取西安市现有集中与分散式污水再生利用典型工程分别进行评价。评价结果与污水再生利用工程实际状况吻合,表明所构建的评价指标体系合理可行,能为污水再生利用系统的规划和管理提供有效依据。

| Abstract: | An evaluation index system was established to assess wastewater reclamation and reuse project.Considering the different characteristics and main factors of the centralized and decentralized wastewater reclamation and reuse engineering,the index system included 13 individual indices in five categories: water quantity,water quality,techniques,economy and management.After the index system had been established,an BP neural network model was used to evaluate a typical project in Xi'an.Results were in good agreem... |
