The utility model belongs to the technical field of
aquaculture, and particularly relates to efficient dissolved
oxygen fine
filtration equipment applied to
aquaculture, which comprises a rough
filtration bin, an input
pipe fitting is arranged at the top of the rough
filtration bin, a rough filtration component is arranged in the rough filtration bin, and the rough filtration component is positioned below the input
pipe fitting; the rough filtration
assembly comprises a filter cover, the filter cover is trumpet-shaped, a blow-off
pipe is inserted into the bottom of the filter cover, and the blow-off pipe penetrates through the side wall of the rough filtration bin; a bottom bin is arranged at the bottom of the coarse filtering bin; a filtering disc, a bracket and an
aeration disc are sequentially arranged in the bottom bin from top to bottom. The coarse filtration bin and the coarse filtration
assembly are matched for use, so that large
suspended solids and part of harmful substances in the
aquaculture water are effectively removed, and the
water quality is preliminarily improved; through the design of the fine filtration equipment, suspended matters and harmful substances in the
water body can be effectively removed on the premise that the
treatment rate is not reduced, so that a healthier and more suitable growth environment is created for aquaculture.
