The invention belongs to the technical field of
wastewater treatment, and particularly relates to an adsorption device for
wastewater treatment. The adsorption device comprises an adsorption tank, a working
barrel, a rotary rod, a liquid inlet
pipe and a liquid outlet
pipe, a support rod is fixedly mounted at the bottom of the inner cavity of the adsorption tank, a top cover is fixedly mounted atthe top of the adsorption tank, the working
barrel is inserted in the adsorption tank, a first adsorption layer is inserted in the top of the inner cavity of the working
barrel, a second adsorption layer is inserted in the center of the inner cavity of the working barrel, a third adsorption layer is inserted in the bottom of the inner cavity of the working barrel, the first adsorption layer is used for absorbing large
impurity particles in water, the second adsorption layer is used for absorbing small
impurity particles in the water, the third adsorption layer is used for absorbing pungent smell and color matter, the liquid outlet
pipe is used for discharging treated
wastewater, the situation that impurities in the wastewater
pile, and consequently the
adsorption effect is influenced can be prevented, the
adsorption effect is improved through multi-layer adsorption, the mosaic structure is convenient to
mount and dismantle, and cleaning is convenient.
