The low order end of filter tank bottom wall, the other end are connected with sedimentation basin, and the sedimentation basin is provided with partition plate, which is divided into two by sedimentation basin
A chamber, the chamber connected with pipeline are water storage settling tank, another chamber excludes pond, the water storage settling tank bottom for floating material
Outlet pipe is connected at portion.
As preference, the turbulence plate is vacantly erected in filtering ponds by the fixed frame being arranged on filtering ponds.
As preference, the floating material excludes to be provided with floating material discharge pipe on the side wall of pond.
As preference, the side wall and bottom wall of the rotation screen drum are the arc-shaped structure of integrally connected, and rotary screen
The barrel dliameter of cylinder is slightly less than the internal diameter of filtering ponds.
Compared with prior art, the utility model has the advantages that：
First, a kind of rotary screen type aquaculture wastewater pretreatment unit described in the utility model, rotation screen drum drives what is collected
Aquaculture wastewater carries out rotation screening, and the fixation dopant in aquaculture wastewater is efficiently filtered out, and is also convenient for filter after the completion of filtering
The fixation dopant gone out clears, simple and practical in structure, in addition, along with the secondary filter of porous disc, realizes the height of moisture
Effect filtering.
Second, a kind of rotary screen type aquaculture wastewater pretreatment unit described in the utility model, turbulence plate can slow down current
Falling speed, prevent current from splashing spray in filtering ponds bottom and causing further muddiness, in addition, water storage settling tank with floating
The removing of floating material remaining first is capable of in the combination in object exclusion pond, easy to operate, simple in structure, and it is low to build maintenance cost.
