In most regions of China, water supply scarcity is barely perceptible—after all, aren’t there abundant water sources within our reach? Consequently, many individuals lack awareness of water conservation. While China boasts relatively rich water resources, pollution remains a prominent issue, making Online Water Quality Monitoring for aquatic environments of great importance.
Does Anyone Still Consider Water Quality Monitoring Insignificant?
Such a mindset is unreasonable. The core objective of water quality monitoring is to quantify the concentrations of various pollutants in water bodies. By analyzing monitoring data and their temporal variations, the quality status of water can be evaluated; in essence, it determines whether a water body is suitable for its intended use. Additionally, monitoring parameters vary across different domains. Pollutants are categorized into types such as total phosphorus (TP), total nitrogen (TN), heavy metals, coliform bacteria, and total residual chlorine. All pollutants must undergo treatment and monitoring to ensure their indices meet regulatory standards before the water is either utilized or discharged.
Water Monitoring Targets can be Broadly Classified Into two Categories:
- Comprehensive indicators reflecting overall water quality, including chemical oxygen demand (COD), biological oxygen demand (BOD), and chromaticity;
- Indicators for detecting toxic substances, such as heavy metals (e.g., chromium, arsenic, lead, cadmium, mercury) and phenols.
The selection of monitoring indicators depends on the specific water quality characteristics of different industries.
We should recognize that water resources are indispensable natural resources for humanity. However, with the continuous expansion of industrial and agricultural activities, water pollution has grown increasingly severe. To ensure water safety, Water Quality Monitoring emerges as a foundational and vital task—it supports the entire framework of water pollution control.
