Research on Hotel Wastewater Treatment System Based on PLC Control

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