Treatment methods for catalysts in wastewater from catalytic flue gas desulfurization
Thread Content
Methods for treating the catalyst in wastewater from catalytic flue gas desulfurization: 1. Use a clarifier, add flocculants and polyaluminum chloride, allow sedimentation, and then pump the slurry to a plate and frame filter press for pressing. 2. Use a sedimentation tank, add flocculants and polyaluminum chloride, allow sedimentation, and then pump the slurry to a plate and frame filter press for pressing. 3. Use a clarifier, add flocculants and polyaluminum chloride, allow sedimentation, and then pump the slurry to a sedimentation tank for natural sedimentation. Which method do you use? What advantages do you think your method has, and what are its disadvantages? Everyone is welcome to discuss this
Plate frames are necessary; the sedimentation method won’t work, and the treatment manufacturers can’t remove them. Environmental regulations are so strict these days. If something goes wrong during transportation, it will cause big problems.
It is currently being upgraded; previously, natural sedimentation was used for water filtration, but its effectiveness was very poor. It was difficult to transfer the wet agents on site, and the costs were high. Prepare to add a pump below the clarifier to pump the fluid to the filter press.
3 We naturally settle in the filtration box! The design institute planned that once it was full, the catalyst processing company would come and take the entire vehicle away! Now, to save money, we use shovels to put the material into the catalyst bags one by one; once it’s dried, it’s taken away along with the balancing agent!
It doesn’t dry even after two months of sun exposure; and when it does dry, it forms lumps with a high level of moisture still remaining inside. It looks very dry after the plate and frame process; the loss on ignition is around 50%.
