the water treatment device of reducing the non point source pollutants of initial rain

摘要

The present invention relates to a device for processing the floating and sedimentation Castle boiling point contaminants from flowing along with the rain water during rainfall, and more particularly is a multi-step having a different diameter as a means for handling the boiling point contaminant particles of large through the perforated plate to separate and remove the solid matter and precipitate removed, and acetic acid efficiently reduced to the boiling point contaminants vinyl resin family distilled off contaminants from the filtration tank filter medium is provided with a material adsorbent initial solid contaminants specific gravity is large in the settling tank using a rotational flow It relates to a water treatment device. The invention screen chamber 20, settling tank 30, the primary treatment tank 40, a filtration tank 50, the final treated water tank 60, water for processing by a reduction in the initial boiling point of the solid contaminant provided contains It provides an apparatus. The invention also doedoe one or a plurality of perforated plate screen 21 is a screen configuration in the chamber 20, Perforated screen is to provide a water treatment device for processing by reducing the boiling point of the initial solid contaminants characterized by the uneven points of the concave-convex shape of the porous screen. In addition, the present invention is to provide a water treatment device for processing by reducing an initial boiling point of the contaminated solid material, it characterized in that the upper is provided with a overflow (31) of the one settling tank (30). In another aspect, the present invention the filtration tank 50 provides a water treatment apparatus for processing by reducing an initial boiling point of the contaminated solid material, characterized in that that contains the suspended filtration unit 50-1. In another aspect, the present invention the height of the height (H) (in the horizontal plane of the said overflow 31 is an open top and an outer wall 31-1 is weir (weir) and a structure the inner wall 31-2 means also) provides a water treatment apparatus for processing by reducing an initial boiling point of the contaminated solid material, it characterized in that it is composed of a higher or a weir wall (weir) structure than the height (a) of the outer wall. The invention also reduces the boiling point of the initial solid contaminants characterized in that said one part is the planetary filtering part 50-1 is configured includes a filter medium 51, the mesh net 52, the filter media support (53) It provides a water treatment apparatus for treatment by. ;
