Notes on Installation and Commissioning of the Online Water Quality Monitoring System

After the on‑site installation and initial test of online water‑pollution‑source monitoring instruments, commissioning shall be carried out with a continuous operation period of no less than 72 hours. Zero‑point calibration and span calibration checks shall be performed every day. If the accumulated drift exceeds the specified index, adjustments shall be made to the online monitoring instruments.

If commissioning is interrupted due to a fault of the emission source or the online monitoring system, commissioning shall restart after the emission source or the system returns to normal, with a continuous operation duration of no less than 72 hours.

High‑quality water resources serve not only as the foundation for the healthy growth of aquatic animals but also as one of the critical conditions for crop ripening and premium quality. Against the current backdrop, Hebei Yutian Environmental Protection Technology Co., Ltd. is committed to improving China’s online monitoring capacity for water pollution. The company has developed an online monitoring system for fugitive water pollution sources. It enables environmental system integrators to achieve better real‑time data analysis and diagnosis, and helps improve domestic water quality. The system supports online monitoring of COD, ammonia nitrogen (\(NH_3‑N\)), flow rate, pH and other parameters. It realizes 24‑hour online data acquisition and upload communication, and is equipped with real‑time alarm functions as well as statistical analysis reports.
