城镇生活污水系统厂网一体化考核体系的构建与应用

Construction and Application of Integrated Assessment System of Urban Domestic Sewage Treatment Plant and Sewage Pipeline Network

为推进我国污水系统厂网一体化运营管理,在调研分析全国城市污水处理厂网运营及考核情况的基础上,以Y市为案例,构建了区级监管考核与企业关联考核相结合的厂网一体化考核体系,将污水处理厂进水水质、入厂污染物总量和污水溢流等纳入考核指标,搭建污水处理厂运行情况挂钩污水管网维护费的关联付费模型。模拟结果表明,通过厂网一体化考核能有效解决污水处理厂网政府监管单位、运营单位及付费主体均不一致带来责罚无法认定的问题,全面提升污水处理厂网运营管养的工作动力,有效减少污水管网运营养护费的投入。

The paper introduces an integrated assessment system for urban sewage treatment plant and sewage pipeline network based on the investigation and analysis of urban sewage treatment plant and sewage pipeline network operation and assessment condition in China,aiming to enhance the coordinated operation and management of sewage systems.Taking Y city as an example,an integrated assessment system for sewage treatment plant and sewage pipeline network was constructed,which combined the two‑level linking assessment of district,along with the bidirectional associated assessment of the enterprise.The assessment indicators will encompass the influent quality,total amount of pollutants and sewage overflow,alongside the establishment of a linked payment model for sewage treatment plant operation and sewage pipeline network maintenance costs.The results indicate that the integrated assessment of sewage treatment plant and sewage pipeline network could effectively solve the problem of unascertainable punishment due to inconsistent responsibility main body of the sewage treatment plant and sewage pipeline network government supervision department,operation organization and payment department.Consequently,the assessment system could significantly enhance the motivation of sewage treatment plant and sewage pipeline network operation and maintenance,potentially leading to a reduction in sewage pipeline network operation and maintenance costs.
