Document Type and Number:
WIPO Patent Application WO/2021/083414
Kind Code:
A2
Abstract:
Disclosed in the present utility model is a stratified purification wastewater treatment apparatus, comprising a sedimentation filter tank, a flocculation tank, and a biological reaction tank, the sedimentation filter tank and the flocculation tank being connected by means of a water delivery pipeline, and the flocculation tank and the biological reaction tank also being connected by means of a water delivery pipeline, a water suction pump A being mounted on the water delivery pipeline between the sedimentation filter tank and the flocculation tank, and a water suction pump B being mounted on the water delivery pipeline between the flocculation tank and the biological reaction tank, a tank cover being disposed on the upper end of the flocculation tank and a dosing tank being mounted thereupon, and a dosing pipe being disposed at a position of the dosing tank inside the flocculation tank; in the present utility model, by means of arranging multiple filter grids on a bottom slope of the sedimentation filter tank and arranging the diameters of the holes of the filter grids from large to small, under the action of the multiple filter grids, the sedimentation filter tank can be separated into multiple filter compartments and floating matter and large particle impurities in the wastewater can be filtered to implement stratified filtration, so that the filter effects are good.
