Xidan JoyCity Catering Wastewater Treatment System Upgrade Project
1 Project Overview
The Xidan Joy City Catering Wastewater Treatment System Upgrade Project is a key environmental infrastructure renovation project located in the core commercial district of Xidan, Beijing.
The project serves a large-scale commercial complex integrating shopping malls, restaurants, and hotel catering facilities. The wastewater contains high concentrations of oil, grease, and organic matter generated by multiple food service operators.
The system upgrade focuses on improving oil-water separation efficiency, drainage stability, and overall compliance performance under high-density commercial operation conditions.
