The underground drainage network environment is complex, with dampness, water accumulation, debris accumulation and poor ventilation. Ordinary monitoring equipment is highly susceptible to environmental interference and has a high failure rate, making it difficult to operate stably for a long time.

The underground drainage network environment is complex, with dampness, water accumulation, debris accumulation and poor ventilation. Ordinary monitoring equipment is highly susceptible to environmental interference and has a high failure rate, making it difficult to operate stably for a long time. The drainage network water quality online monitoring system of Shandong Dongrun Instrument is specially designed for harsh underground working conditions. It is suitable for installation and use in various municipal and industrial park underground pipelines. It has extremely strong applicability and stability.
The equipment adopts industrial-grade waterproof and dustproof, corrosion-resistant design, which can adapt to long-term damp and waterlogged underground environments. It is equipped with high-precision sensor units and can stably monitor core water quality indicators such as COD, ammonia nitrogen, pH, turbidity, total phosphorus, and total nitrogen of the pipeline network around the clock. It eliminates problems such as data drift and monitoring failure. The system operates automatically throughout the process, eliminating the need for frequent manual downhole maintenance and sampling. This not only avoids safety risks in underground operations but also saves a significant amount of manpower and resources.
The system can accurately detect hidden pollution problems such as instantaneous over-limit of pipelines, night-time illegal discharge, rainwater overflow, and rainwater and sewage mixing. Abnormal water quality is automatically warned, helping maintenance personnel quickly locate the problem location and trace the source of pollution. It also supports real-time data upload and long-term storage, and can seamlessly connect with smart water management and environmental protection supervision platforms, fully complying with environmental monitoring standards. With its strong adaptability, high stability, and simple operation, it has become the preferred equipment for intelligent monitoring of underground drainage networks and regular water quality control.
