Domestic wastewater refers to water discharged after domestic use in daily life. However, current observations indicate that a substantial volume of domestic wastewater is still discharged directly into rivers without treatment. This issue is particularly acute in rural areas and small cities, where environmental pollution caused by such discharge is far more severe and thus requires urgent attention. Therefore, the implementation of domestic Wastewater Monitoring holds great significance.
Domestic wastewater contains complex and diverse pollutants, and no single treatment method can achieve complete purification. For this reason, addressing the problem at its source is critical—a principle emphasized by environmental protection equipment networks. Common pollutants in wastewater include total phosphorus, ammonia nitrogen, total nitrogen, chemical oxygen demand (COD), and petroleum hydrocarbons. By detecting relevant indicators, the extent of water pollution can be accurately assessed. The significance of domestic wastewater monitoring is reflected in the following aspects:
1.Tracking Water Quality Trends: Real-time monitoring of domestic wastewater enables data-driven assessment of pollution in surface water bodies (e.g., rivers, lakes, and oceans), facilitating a clear understanding of current water quality status and its evolutionary trends.
2.Supporting Pollution Management: Monitoring different types of domestic wastewater provides a scientific basis for formulating pollution control strategies and ensuring compliance with wastewater treatment standards.
3.Guaranteeing Environmental Compliance: It helps verify whether treated water meets relevant quality standards, serving as a key reference for environmental protection supervision.
4.Facilitating Technological Innovation: In research on water treatment and quality monitoring, monitoring data supports the evaluation of new technologies and methods.
5.Informing Regulatory Framework: It provides fundamental data for the development and adjustment of wastewater monitoring systems and policies.
Despite these recognized benefits, untreated domestic wastewater discharge remains prevalent in many regions. Barriers include reluctance to install treatment facilities due to perceived inconvenience, as well as infrastructural limitations—such as outdated domestic waste collection pipelines in some areas—which impede the stable and effective operation of wastewater treatment plants.
