ある。In addition, activated carbon treatment decolorizes and removes COD by passing the liquid to be treated through an activated carbon layer packed in a column, but since activated carbon is not a chemical and is regenerated by high-temperature heating, it is impossible to regenerate it in an adsorption column. It is. Therefore, the tedious work of transferring activated carbon between the adsorption column and the regeneration furnace is required. In order to solve this problem, is there any automated equipment for transfer and production, such as suction as an adsorption device, extracted activated carbon TL, new charcoal IFi, same GT), etc.
In addition, there are 11 regeneration devices such as a regeneration furnace, a corpse gas cyclone, a waste gas combustion furnace, a coal storage tank, an apricot charcoal cooling tank, an internal coal slurry shield, etc., and in the case of ozone treatment. Similarly, there are 8 listening points which require complicated equipment.
