摘要
汉口片区多年来持续进行排水管网及排水设施建设,但尚未对排水管网系统及配套设施进行过系统、具有针对性且较为客观的评估研究,对于排水管网系统及配套设施建设的自我完善造成了较大的影响。文中通过建立排水管网系统运行效能综合评估指标体系来衡量汉口地区排水管网系统的完备程度、服务水平及承载能力,为制定合理的设施提效工程方案、后续管控以及最终转化成为行政考核管理的办法提供依据。评估结果表明,系统连接问题多,旱季排水设施运行效能低,雨季排水设施评估中分流制、合流制溢流污染问题较为严重,混错接导致雨水混接入污水量情况较好。并结合评估结果提出了制定“一厂一策”系统化整治方案等相应的改进措施。
The construction of drainage pipe network and drainage facilities in Hankou area has been carried out continuously for many years,but there is no systematic,targeted and objective evaluation and research on the drainage pipe network system and supporting facilities.There is a great impact on the self-improvement of the drainage pipe network system and supporting facilities.In this paper,the comprehensive evaluation indicator system of the operation efficiency of the drainage pipe network system was established to measure the completeness,service level and carrying capacity of the drainage pipe network system in Hankou area.To provide a basis for the formulation of a reasonable project plan for improving the efficiency of facilities,follow-up management and control,and finally transformed into administrative assessment and management.The evaluation results showed that there were many problems in the system connection,the operation efficiency of drainage facilities was low in dry season.In the evaluation of drainage facilities in rainy season,the overflow pollution problem of diversion system and confluence system was more serious,and the mixed misconnection leads to the mixing of sewage water quantity of rain water was better.Combined with the evaluation results,the corresponding improvement measures such as formulating a systematic rectification plan of"one system,one solution"were put forward.
