广东省农村生活污水治理成效评估体系构建及应用
- Title:
- Construction and Application of Evaluation System for Rural Domestic Sewage Treatment in Guangdong Province
- Keywords:
- rural domestic sewage; variation coefficient; differentiated contribution degree; evaluation system for treatment effectiveness
- 摘要:
- 为精准评价农村生活污水治理成效，基于层次分析法-模糊综合评价法构建农村生活污水治理成效评估体系。同时选择农村生活污水治理常用的建设处理设施、纳入污水处理厂和资源化利用模式开展应用研究，通过变异系数考察各评价指标打分的差异性，基于差异性贡献度量化各评估指标打分差异性对治理成效评价一致性的影响程度及规律。评价结果证实，基于层次分析法-模糊综合评价法构建的评估体系具有可行性，可作为评估农村生活污水治理成效的工具。鉴于管网建设规范性、管网运行情况、设施运行情况、受纳体选用规范性、资源化利用路径完整性对治理成效评估体系评价结果一致性的影响较大，建议评估过程中对上述指标投入更多关注。
- Abstract:
- To accurately evaluate the effectiveness of rural domestic sewage treatment, this study develops an evaluation system based on the analytic hierarchy process (AHP)-fuzzy comprehensive evaluation method. Commonly used construction facilities, sewage treatment plant designs, and resource utilization models for rural domestic sewage treatment were selected for application research, and the differences in scores for each evaluation index were analyzed using the coefficient of variation. The influence and pattern of score differences for each evaluation index on the consistency of treatment effectiveness evaluation were quantified based on the contribution of each difference. The results confirm that the evaluation system based on AHP-fuzzy comprehensive evaluation method can be used as a feasible tool to evaluate the effectiveness of rural domestic sewage treatment. Given that network construction norms, network operation conditions, facility operation conditions, acceptor selection standardization, and resource utilization path integrity have a great impact on the consistency of the evaluation results of the evaluation system, it is suggested that greater attention should be given to the scoring process of these indicators.
