Traditional water quality monitoring in drainage networks relies heavily on manual sampling and laboratory testing, resulting in delayed data and incomplete coverage, making it difficult to meet the current demands of smart water management and stringent environmental regulations.

Traditional water quality monitoring of drainage networks mostly relies on manual regular sampling and laboratory analysis, resulting in lagging data and incomplete coverage, making it difficult to meet the current demands of smart water management and strict environmental control. The online water quality monitoring system for drainage networks by Shandong Dongrun Instrumentation breaks through the shortcomings of traditional monitoring and realizes 24/7, automated and precise monitoring of water quality in drainage networks.
This system can continuously monitor core water quality indicators such as COD, ammonia nitrogen, pH, turbidity, total phosphorus, and total nitrogen in the network without the need for frequent manual operations in the wells, avoiding safety hazards such as dampness, lack of oxygen, and water accumulation in the wells. Compared with fragmented data from manual single-point sampling, online monitoring can record real-time changes in water quality throughout the process and accurately capture hidden pollution problems such as night-time illegal discharges, instantaneous exceedances, and rainwater overflows.
The equipment is specially developed for the harsh working conditions of underground networks, with anti-interference, corrosion resistance, and stable operation, and can operate without human supervision for a long time. Water quality data is automatically uploaded to the platform in real time, and abnormal exceedances are immediately detected and warned intelligently, helping maintenance personnel quickly trace the pollution source and accurately identify problems such as rainwater and sewage mixing, pipe damage, and illegal discharges. At the same time, it supports permanent data retention and one-click export, and can seamlessly connect with environmental protection supervision and smart water management systems to meet environmental verification compliance requirements, significantly reducing maintenance labor costs and significantly improving the digital and refined management level of urban drainage networks.
