Monitoring Platform Integration Service Project

River Water Monitoring Project

The river water monitoring project is a core environmental engineering initiative aimed at fulfilling the responsibility for watershed ecological protection, preventing water environment risks, and improving the intelligent level of river water quality control. The project focuses on various natural rivers, artificial channels, and tributaries, establishing a comprehensive, round‑the‑clock, and precise online monitoring system. It fully captures the dynamics of river water quality, provides timely warnings of potential pollution hazards, and offers solid technical support for river water environment treatment, ecological restoration, and environmental supervision.

Currently, rivers face multiple pressures such as inflow of domestic sewage, agricultural non‑point source pollution, illegal discharge of industrial wastewater, and eutrophication. Additionally, monitoring points are scattered and cover large spans. Traditional manual sampling monitoring suffers from long cycles, delayed data, limited coverage, and untimely emergency response. These shortcomings fail to meet the control requirements of the River Chief System and the relevant provisions of the Environmental Quality Standards for Surface Water (GB 3838‑2002). To address these monitoring gaps and build a strong ecological barrier for the watershed, this river water monitoring project has been launched. The project centrally deploys the outdoor 1105E stainless steel water quality monitor, leveraging its professional performance to adapt to the complex outdoor conditions of rivers. It achieves precise monitoring of river water quality across the entire range and over all time periods, promoting a shift in river water environment supervision from “post‑incident response” to “pre‑event prevention and real‑time control.”

Monitoring System and Deployment

This project combines the characteristics of the river basin, the distribution patterns of pollution sources, and ecological protection needs. Monitoring points are scientifically deployed to achieve full coverage of the river area. Key monitoring points are located at river inlets, critical cross‑sections, and surrounding sensitive areas, while also covering segments prone to pollution recurrence and large water quality fluctuations, ensuring comprehensive capture of water quality dynamics. The monitoring focuses on conventional core indicators such as water temperature, pH, dissolved oxygen, electrical conductivity, turbidity, COD, ammonia nitrogen, total phosphorus, and total nitrogen. All monitoring strictly follows national surface water environmental monitoring standards and relevant technical specifications, ensuring that the data are accurate, reliable, and compliant with regulatory requirements. The system fully reflects the river water quality status and pollution trends, providing precise data support for pollution source tracing and governance decisions.

Core Equipment – Outdoor 1105E Stainless Steel Water Quality Monitor

The core equipment used in the project is the outdoor 1105E water quality monitor, specifically designed for the complex conditions of outdoor rivers. It features an explosion‑proof enclosure made primarily of stainless steel, offering significant advantages in terms of waterproofing, dust resistance, and corrosion resistance. It has a high protection rating, enabling stable operation in complex outdoor environments such as high and low temperatures, heavy rain, high humidity, and dusty conditions. It is not easily affected by impurities in the water or external environmental interference and has a long service life.

The equipment integrates automatic sampling, automatic pretreatment, automatic detection, automatic cleaning, and automatic calibration. It can operate continuously 24/7, significantly reducing manual maintenance workload, avoiding the inconvenience and safety risks of outdoor manual inspections, and effectively meeting the monitoring demands of large water quality fluctuations and complex compositions. Furthermore, the equipment supports 4G/NB‑IoT wireless data transmission technology, enabling real‑time upload of monitoring data to a platform for real‑time data viewing and automatic alerting of abnormal indicators. When monitoring data exceed the standard threshold, the system rapidly triggers multi‑level alert signals, allowing staff to promptly identify pollution sources and take emergency response measures to prevent the risk of water pollution spread. The equipment can also be interfaced with an IoT cloud platform to achieve data collection from multiple stations with a single source and coordinated scheduling.

Project Outcomes and Significance

The implementation of this project has comprehensively improved the intelligence and precision of river water quality control, effectively addressing the shortcomings of traditional monitoring methods and achieving closed‑loop management of “real‑time monitoring, precise early warning, rapid response, and full‑process control” for river water quality. This aligns with the national requirements for implementing the River Chief System and protecting watershed ecology.

The project not only provides accurate data support for river management authorities to understand water quality dynamics, identify pollution risks, optimize control measures, and carry out ecological restoration – helping to improve river water environment treatment efficiency and enhance watershed ecological quality – but also ensures that river water quality remains stable and compliant, effectively prevents water pollution incidents, and safeguards the safety of production and domestic water for residents within the basin as well as the aquatic ecological balance. Moreover, the implementation of this project improves the regional river water environment monitoring system, promotes the coordinated development of watershed ecological protection and the economy and society, and offers a replicable and scalable intelligent solution for water quality monitoring of various rivers, helping to build a strong ecological security barrier for the watershed.
