Research on Hotel Wastewater Treatment System Based on PLC Control

Abstract

This study investigates a small-scale wastewater treatment system for a small restaurant, which combines biological and physical treatment methods with a PLC control system to meet national environmental requirements. The system utilizes a PLC controller for automatic control, achieving efficient and stable treatment processes. Through experiments and analysis, it has been demonstrated that this system performs better than conventional methods in terms of degrading COD, BOD5, and SS, effectively meeting the wastewater discharge standards for restaurants. The system offers advantages such as automatic control, high efficiency, and stability, providing valuable references for wastewater treatment in restaurants and other public facilities.
