Project Overview
- An Ordos New Energy Vehicle Industrial Park integrates vehicle assembly, components, and powertrain manufacturing, with a planned total investment exceeding RMB 30 billion. The park focuses on intelligent connected and new energy vehicle models, equipped with complete four-process production lines.
- The project is designed with a treatment capacity of 120 m³/h for dewatering water reclamation and reuse.
- The dewatering water primarily consists of groundwater discharged from coal/ore mining operations. The water quality is generally fair, ranging from neutral to weakly alkaline, with elevated salinity and hardness, along with trace amounts of iron, manganese, and suspended solids.
Key Technical Challenges
- The dewatering water exhibits high hardness, high salinity, and high turbidity, making membrane systems susceptible to scaling and fouling. Deep softening and desalination, along with stable membrane system operation control, present significant challenges.
- Raw water quality fluctuates noticeably with mining conditions, while the reuse standards are stringent. This requires a balanced approach encompassing pretreatment reliability, membrane system fouling resistance, and operational cost-effectiveness.
