Research on Remote Monitoring System for Zero Discharge Treatment of External Cooling Water in Converter Valve

摘要

A sewage treatment remote monitoring system is designed in this paper due to long physical distance, complex process of zero discharge treatment techonology that requires monitoring. The paper firstly introduces the external cold water discharge of the valve cooling system of the converter station, and proposes the treatment measures for zero discharge of sewage in the case of phosphate, COD and salt in the discharged wastewater. The remote monitoring system is designed according to the process routes of the zero-emission scheme. The system adopts a hierarchical network control structure and mainly includes locale execution layer, harmonization layer, and remote monitoring layer. The mechanisms and functions of each layer are introduced in detail. The remote monitoring system is effective in monitoring the water treatment process and is helpful to achieve zero discharge of external cooling water in converter valve.
