- Abstract:
- To solve the problem of low influent concentration and high load operation of the sewage treatment plant in a river network area in south China, the backflow points were investigated by the joint dispatching strategy of sewage treatment plant, sewage pipeline network, and river system, according to the local conditions. The spatial distribution, topology relationship, and its influence on the water quality of the sewage treatment plant were estimated. After removing the impact of backflow points, the influent ammonia nitrogen concentration of the sewage treatment plant can be increased by 25.2% based on the measurement. Based on the analysis results, the technical measures such as adding anti-backflow facilities, rectifying traceability cation, repairing the damaged pipeline, and strengthening pump & gate management have been proposed.
