Water supply network of an industrial park in Shandong Province

Online Water Quality Monitoring Project for the Water Supply Pipeline Network of an Industrial Park in Shandong Province

This project is an intelligent monitoring initiative designed to fully ensure the safety of production water for enterprises within the industrial park, standardize the operation and maintenance management of the water supply pipeline network, and fulfill the responsibility of water quality supervision. The project strictly complies with the Standards for Drinking Water Quality (GB 5749‑2022) and relevant regulations for urban water supply quality management. Taking into account the layout characteristics of the park’s water supply network and the water demand of enterprises, a full‑process online monitoring system has been established covering the water source, main pipelines, branch nodes, and the inlets of key industrial water users. This effectively fills the gap in real‑time water quality monitoring of the park’s water supply network and provides a solid safety barrier for the high‑quality development of the park.

Leveraging electrode‑based online water quality monitoring technology, the project rationally deploys online water quality monitoring equipment at core points such as the outlet of the park’s water treatment plant, key nodes of the main pipeline network, secondary water supply facilities, and the water inlets of major enterprises. The equipment focuses on monitoring key water quality indicators including pH, residual chlorine, electrical conductivity, dissolved oxygen, and turbidity, enabling 24/7 continuous, real‑time, and precise monitoring of water quality in the supply network. Measurement errors are controlled within ±2%, and the T95 response time can be as short as 5 seconds, allowing rapid detection of abnormal water quality fluctuations. All monitoring devices are connected to the park’s integrated smart water management platform, enabling remote transmission, storage, query, and trend analysis of monitoring data. An automatic alarm function for exceedances is built in: once a water quality parameter exceeds the standard threshold, an audible and visual alarm is immediately triggered, and early‑warning information is pushed to operation and maintenance personnel, facilitating rapid identification of risks and implementation of corrective measures to prevent water quality safety incidents.

Furthermore, considering the high water demand and wide coverage of the pipeline network in the industrial park, the project adopts integrated modular monitoring equipment that offers advantages such as corrosion resistance, anti‑interference capability, and ease of maintenance. The equipment has a protection rating of IP65 or higher, making it suitable for the complex industrial environment of the park. It effectively shields water quality interference caused by industrial activities, ensuring stable and reliable monitoring data. Through the implementation of this project, the park has achieved a transformation in water quality management from “passive testing” to “active warning” and from “extensive management” to “precise control.” This not only ensures the safety of production water for enterprises in the park but also provides scientific data support for optimizing pipeline network operations, leak detection and control, and water quality management. The project helps the park build a full‑chain smart water supply guarantee system, practice the concept of green development, and promote the coordinated development of ecological environmental protection and industrial production.
