Tunnel Sewage Treatment Equipment
Designed for tunnel construction wastewater with high suspended solids, turbidity, and pH. Integrates coagulation-precipitation and filtration in a skid-mounted unit that relocates with excavation, suitable for tunnels, subways, and underground projects.
- Designed for high turbidity and high SS wastewater with ample sedimentation capacity and strong shock resistance.
- Integrated coagulation dosing, sedimentation, filtration, and pH adjustment for clear, stable effluent.
- Skid-mounted structure; relocated in sections as the face advances, with a short installation cycle.
Product Overview
The tunnel sewage treatment equipment is an integrated system designed for wastewater generated during drill-and-blast and shield tunneling construction. Tunnel wastewater originates from drilling, blasting, grouting, spray dust suppression, and vehicle washing. It is characterized by high suspended solids concentration, high turbidity, elevated pH levels, and significant fluctuations in instantaneous flow rates. The system employs a combined process of equalization, coagulation, sedimentation, filtration, and pH adjustment. Designed as a skid-mounted integrated unit, it handles flow rates of 20-50 m³/h. The treated effluent meets the "Comprehensive Wastewater Discharge Standard" and local pipe connection requirements. The clarified water can be recycled for dust suppression spraying and vehicle washing.
Product Features
- 01Designed for high turbidity and high SS wastewater with ample sedimentation capacity and strong shock resistance.
- 02Integrated coagulation dosing, sedimentation, filtration, and pH adjustment for clear, stable effluent.
