Construction and application practice of online monitoring system for water quality in water plants
The water quality online monitoring system of water plants is the core technical support for ensuring drinking water safety. It realizes full-process water quality control through real-time and intelligent monitoring methods. The front-end of the system is deployed in the water source area to conduct 24-hour dynamic monitoring of key parameters such as ammonia nitrogen, nitrite, permanganate index, turbidity, alkalinity and hardness in the raw water, and timely identify pollution risks through the data anomaly warning mechanism, providing a scientific basis for water source protection.
In the water treatment production process, the monitoring system covers key process nodes such as coagulation, sedimentation, filtration, and disinfection, focusing on monitoring indicators such as turbidity removal effect, residual chlorine/total chlorine disinfection efficiency, chlorine dioxide dosage, and ammonia nitrogen residue. The system uses Internet of Things sensing technology to realize automatic collection and remote transmission of monitoring data, ensuring that various water quality parameters during the production process are always within a controllable range.
The data is gathered to the central control room through the industrial bus, and is analyzed and visualized in multiple dimensions using professional software. Based on the real-time monitoring results and combined with the tap water treatment process model, technicians can accurately adjust the mud discharge cycle of the sedimentation tank, the backwash intensity of the filter and the operating parameters of the dosing equipment to achieve dynamic optimization of the dosage of chemicals, thereby reducing operating costs while ensuring that the effluent quality meets standards.
The application of this system has significantly improved the level of refinement of water plant management. By building a full-chain monitoring network from source water to factory water, it not only meets the rigid requirements of the "Drinking Water Hygienic Standards", but also provides data support for process improvement, ultimately achieving the dual goals of safe water supply and economic operation of water plants.
