上海分流制污水系统运行状况评价研究

Evaluation and Study on Operational Condition of Separated Sewage Systems in Shanghai

摘要:

分流制污水系统是上海目前主要的排水体制，有必要构建评价系统综合掌握其运行状况。调研了16项相关的国家、行业、地方和团体标准，建立了包含3层网络层次结构的分流制污水系统运行状况评价体系，涵盖了结构属性、功能属性、混接及入渗属性和资料完备属性下的20个评价指标。同时，采用专家问卷调研与层次分析（AHP）的方法，确定了各层次指标的权重和相应的评价等级。评价体系有望为相关运营维护工作提供支持，助力提高污水系统的管理水平。

Abstract:

The separated sewage system is the main drainage system in Shanghai now. It is necessary to build the evaluation system to comprehensively master its operational status. The 16 relevant national， industry， local and group standards are investigated. The evaluation system of operational status of separated sewage system containing a three-layer hierarchical network structure is established to cover 20 evaluation indexes under the structural attribute， functional attribute， mixed connection and infiltration attribute and data completeness attribute. Additionally， the expert questionnaire investigation and the analytic hierarchy process (AHP) are used to determine the weights and corresponding evaluation grades of the indicators at each level. The evaluation system is expected to provide the support for the relevant operational and maintenance， and improve the management level of the sewage system.
