However, the landfill does not accept calcium fluoride sludge, so landfill is not feasible, and only recycling is considered.
Calcium fluoride sludge can be made into ceramics and calcined with domestic sludge as cement additive, but the sludge must be dried.
I suggest that the sludge treatment equipment combining solar energy and heat pump be used to treat calcium fluoride sludge.
The equipment is low temperature treatment, equipped with gas detection device, real-time monitoring, safety and environmental protection, to avoid secondary pollution.
With computer automatic control, sludge can be dried to a water content below 30%, and 50-2,000 tons of sludge can be treated every day, and it will be granular after drying.
Our company cooperated with many enterprises to recycle sludge, and the environmental protection bricks made from it won many national patents.
