- Abstract:
- The problem of black and odorous water in a district of a southern city is becoming more and more serious. Source control and sewage interception are the premise and foundation of black and odorous water treatment. In order to control the source and cut off the pollution, it is necessary to trace the source. However, the complicated pipelines at the intersection of road 1 and road 2 in the district, make it difficult to use conventional tracing methods, such as CCTV and QV detection technology, which are easy to be affected by the water mist in the pipeline and box culvert, take a long time, and cannot trace the target outlet accurately. It only took 3 days to find out the three outlets including PW50, PW51 and PW52 at the intersection by pipeline potential detection technology, and the upstream checking well W3 and W1 of PW51 and PW52 were found out. Compared with the conventional tracing method, it is more efficient and can provide reference and guidance for other similar projects.
