- Abstract:
- The overflow pollution of the combined drainage system is becoming more serious as the rapid urbanization. How to make full use of the drainage pipe network to reduce the overflow pollution during rainy days has become a hot research topic. An online water quality monitoring system was established to monitor the COD information at the overflow and sewage gate of the drainage system in real-time, and then the sewage gate scheduling strategy was formulated based on the real-time monitoring water quality data. The accuracy and stability of the water quality analyzer were tested. The analyzer was installed at the monitoring point and monitored continuously for 30 days with a sampling interval of 10 minutes. Eight days of online monitoring data were randomly selected for comparison with the manual sampling and testing results. The online water quality analyzer was stable and reflected the water quality change in time and sensitively. The comparison between the online monitoring data and manual testing data indicated that 85% of the data deviations were no more than 15 mg/L, which met the requirements of the auxiliary scheduling decision. The system ran well during a long period of continuous monitoring over nearly 8 months and had good application prospects in auxiliary drainage system scheduling.
