North College Vocational Technology Reclaimed Water Treatment Project
1 Project Overview
The Inner Mongolia North Vocational and Technical College Reclaimed Water Treatment Project is a key water-saving and ecological infrastructure project supporting green campus development in Hohhot City, Inner Mongolia.
The system treats domestic wastewater generated on campus and upgrades it into high-quality reclaimed water for irrigation, toilet flushing, road cleaning, and landscape replenishment, enabling internal water circulation and sustainable water use.
