Jiahu Bay Desulfurization Wastewater Project

Project Type: Transformation

This project transformed an existing desulfurization wastewater treatment system to improve efficiency and reduce costs.

Process Flow:

1. Desulfurization wastewater is pumped into a high-efficiency reactor.
2. Simultaneously, an integrated high-efficiency water purification agent is precisely fed into the reactor using a dry powder dosing machine.
3. A high-speed mixer ensures thorough mixing of the agent and wastewater, promoting the formation of large flocs.
4. The well-mixed wastewater is pumped into high-efficiency cyclone clarifiers for further flocculation, precipitation, and clarification.
5. Concentrated sludge settles at the bottom of the clarifiers and is fed, along with the underflow from the gypsum cyclone, to a disc dewatering machine for dehydration.
6. Treated clean water overflows from the clarifiers and is collected in a clean water tank for reuse.

Equipment Features and Advantages:

• Simple process with minimal equipment: The system primarily uses 1 high-efficiency reactor, 2 high-efficiency cyclone clarifiers, 2 wastewater lifting pumps, and 2 sludge transfer pumps.
• Highly automated and easy to operate: The system can be started and stopped with a single button, minimizing operator intervention.
• Compact footprint and low civil construction costs: The entire system occupies less than 30 square meters, reducing infrastructure needs.
• Low operating cost: The system requires only one chemical, resulting in a treatment cost of 3-4 yuan per ton of water.
• Stable operation and excellent water quality: The system ensures consistent performance and effluent that meets regulatory discharge standards.

Customer Pain Points Addressed:

1. Reduced operating costs
2. Enhanced system stability
3. Lowered workload for operators (compared to the complex, labor-intensive operation of the previous system)
4. Consistent water discharge quality meeting regulatory standards
