Subject :Can coal-based columnar activated carbon be used for municipal sewage treatment?
The coal-based columnar activated carbon is made of high-quality anthracite as the raw material, refined and processed by advanced technology, and the appearance is black cylindrical particles; it has a reasonable pore structure and good adsorption performance. activated carbon factory Coal-based columnar activated carbon is the last step in urban sewage treatment. Because its role is to ensure that the columnar activated carbon manufacturers meet the water quality standards after treatment in the municipal sewage treatment plant.
The main functions of coal columnar activated carbon:
Perform the final deep purification of the previously treated water, adsorb the organic matter and impurities in it, reduce the chroma in the water, remove the odor in the water, filter the impurities and suspended solids in the water, and reduce the content of heavy metals. Coal-based columnar carbon used in urban sewage treatment The index is not demanding, mainly depends on the iodine value and strength.
Matters needing attention when coal-based columnar activated carbon is adsorbed:
1. Before loading: it must be filtered to remove the dust generated during storage. When loading, it is not allowed to pour coal-like columnar charcoal directly from the upper port. Coal-bed columnar carbon should be evenly dispersed on the surface of the carbon layer to prevent gas drift. After loading and before operation, the air should be blown out and the carbon powder attached to the surface of the coal-shaped columnar carbon particles should be removed to prevent the coal-based columnar activation from blowing the carbon powder to the lower part to affect production.
2. Feeding link: Open the 50kg coal-based columnar carbon package, and fill the loose coal columnar carbon into the activated carbon adsorption tower.granular carbon The weight of the filler is usually filled in the tank, and the frequency of addition is based on the effect.
3. Regular inspection: strictly test the adsorption effect of coal columnar carbon adsorption tower.
4. The coal-based columnar carbon after long-term adsorption will lose its function, the coal-like columnar carbon is saturated, and the coal-like columnar carbon that has reached saturation is taken out.
4.The treatment of saturated coal-based columnar carbon should go through regular channels. |
