Abstract
The utility model discloses filling for sewage treatment, which comprises a column body. The surface of the column body is provided with a plurality of strip-shaped grooves or spiral hollow grooves; the inner part of the column body is at least provided with one thin sheet; the column body and the thin sheet are often made of modified polypropylene or modified polyethylene. The filling for sewage treatment of the utility model has the advantages that the producing technology is simple, the filling for sewage treatment can be formed by the plastic extruding realized by a common plastic machine, the material source is wide and market selling polypropylene or the modified polyethylene can be used for producing the filling for sewage treatment after processed in hydrophily and modification. Because the surface area rate is large, the quantity of the filling used for a sewage treatment engineering is less, therefore the engineering cost is reduced.
Description
Technical field:
The present invention relates to a kind of filler, particularly a kind of sewage disposal filler.
Background technology
Over nearly 200 years, municipal sewage treatment from primary handle naturally, simple one-level handles to develop into and utilizes various modern techniquies, deeply treating wastewater, and reuse.Wherein, biological contact oxidation process comparatively generally uses in sewage disposal, and the core technology of production contact oxidation method is biomembranous carrier-filler.At present, commercially available sewage disposal filler, wetting ability is not strong, and specific surface area is little, and density is wayward, is deposited at the bottom of the sewage lagoon easily or floats on the water surface.
Summary of the invention
Goal of the invention of the present utility model is to provide that a kind of wetting ability is strong, specific surface area is big, be suspended in the sewage disposal filler in the sewage lagoon.
Sewage disposal of the present utility model with the technical scheme of filler is:
A kind of sewage disposal filler comprises cylinder, and described damaged surface has several bar shapeds to collude groove or volution dead slot, and the inside of cylinder is equipped with at least one plate sheet, and cylinder, sheeting adopt modified polypropene or modified poly ethylene usually.
The sewage disposal filler of the utility model patent, because of bent several bar shapeds of damaged surface are colluded groove and column body is equipped with at least one plate sheet, can significantly improve packing specific area, if adopt the cross core thin slice, sewage disposal of the present utility model generally can increase specific surface more than 100% than the isostructure filler with filler.Simultaneously, because of wetting ability after polypropylene or the modified poly ethylene modification increases, the wetting ability of filler also increases, good sewage processing effect.In addition, sewage disposal of the present utility model is also controlled easily with the density of filler, and during use, filler can not be deposited at the bottom of the sewage lagoon or float on the water surface, but is suspended in the sewage.
The sewage disposal filler of the utility model patent, complete processing is simple, use common plastics machinery extrusion molding to get final product, material source is extensive, select commercially available polypropylene or modified poly ethylene to get final product through hydrophilically modified processing, again because of specific surface area is big, the used filler comparatively small amt of sewage treatment project, engineering cost also decreases.
