- 摘要:
- 采用基于管网模型与多参数智能在线监测设备相结合的数值化诊断方法“管网医院”,可对静态设施属性进行分析,解决管网的拓扑与状态问题;对动态运行数据进行分析,解决管网的监测与运行问题。针对佛山市顺德区某污水处理厂服务范围内污水管网系统的入流入渗问题进行了空间分布解析,并诊断出污水管网外来水入流量和污水溢流量。结果表明:污水主干管网存在81个污水溢流排放口、2处孤立管段、1处大管接小管和1处逆坡管段;污水处理厂大部分时段处于高水位运行状态,导致污水外溢,应将现状末端窨井的水深由7.50 m降至6.22 m,保证旱季各溢流口无污水溢流;占污水管网总长6.7%的局部管段,其外来水入流量占总入流量的47.3%,对污水管网入流情况严重和较为严重的3处管段进行修复,可显著降低整个管网系统的入流量等级。
- Abstract:
- This paper proposed the numerical diagnosis method “pipe network hospital” based on the combination of pipe network model and multi-parameter intelligent online monitoring equipment, which was capable of analyzing the attributes of static facilities and solving the topology and status problems of pipe network. In addition, the method could also analyze the dynamic operational data to solve the monitoring and operational problems of pipe network. The spatial distribution of sewage pipe network inflow and infiltration in the service area of a sewage treatment plant in Shunde District, Foshan City was analyzed, and the volumes of sewage overflow and inflow caused by external water were calculated. There were 81 overflow discharge outlets, 2 isolated pipe sections, 1 large pipe connecting small pipe and 1 reverse slope pipe section in the main sewage pipe network. The sewage treatment plant was operated at a high water level for most of time, resulting in sewage overflow. Therefore, the current water depth of the terminal manhole should be reduced from 7.50 m to 6.22 m to ensure that no sewage overflow occurred at each overflow mouth in the dry season. In the local section which accounted for 6.7% of the total length of the sewage pipe network, the inflow caused by external water accounted for 47.3% of the total inflow. Therefore, repairing the three sections of sewage pipe network with serious or relatively serious inflow problems could significantly reduce the inflow level of the entire network system.
