The sewage treatment plant is equipped with online monitoring systems for key water quality parameters, including chemical oxygen demand (COD), ammonia nitrogen, total phosphorus, and total nitrogen. Continuous measurement of these indicators enables assessment of the environmental impact of effluent discharge and verification of compliance with regulatory discharge standards. Furthermore, the collected data provide a scientific foundation for optimizing and adjusting the wastewater treatment process. These real-time monitoring results also serve as critical references for environmental protection authorities and regulatory bodies during inspections and compliance evaluations.
