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.

Introduction

The discharge of cold water outside the converter station accounts for more than 90% of the total discharge of the converter station. Therefore, how to efficiently deal with the discharge of cold water outside the converter valve is of great significance. On the basis of summarizing relevant literature and data as well as water quality testing data of cold water outside each station, this paper puts forward the technical scheme of zero discharge of cold water outside the station 1 . Zero discharge is an ideal closed water system, without external drainage. The water in the system is constantly recycled or reused after treatment, so as to save water resources and protect the environment 2 , which requires real time monitoring of the water treatment situation in different processes. A 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 3 . 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.
