Abstract
The utility model discloses a kind of Assembled two-layer polyurethane foam carrier, it comprises that profile is the hard porous polyurethane foam shell of regular cube or rectangular shape, this hard porous polyurethane foam shell center is provided with diameter of Spherical Volume, on one of them surface of this hard porous polyurethane foam shell, offer the passage being communicated with diameter of Spherical Volume, in diameter of Spherical Volume, be filled with spherical soft cellular polyurethane foaming lining.Double-layer combined polyurethane foam carrier of the present utility model has good permeability and specific surface area, be conducive to the diffusion of dissolved oxygen, ammonia radical ion, nitrate radical etc., be conducive to the biofilm of mud and the formation of anaerobic environment simultaneously, effectively raise biofilm speed and quality, and this double-layer combined polyurethane foam carrier can adsorb mud of different nature in shell and inner bag, make inner mud more easily keep anaerobism, outside mud can keep highly active aerobic sludge, thereby can further improve processing power.
Description
Technical field
The utility model belongs to water-treatment technology field, and definite saying relates to a kind of Assembled two-layer polyurethane foam carrier.
Background technology
Polyurethane foam carrier is as a kind of use ripe carrier for many years, can be widely used in the sewage disposal scheme of different process, different quality, because it has multifrequency nature, and can carry out as required the feature of multistage modification, a brand-new material of field of waste water treatment is also listed in by EPA, also as major fields, researches and develops at home at present.
The density of polyurethane foam carrier can be carried out modification as required, thereby its density is fluctuated at 1g/cm3, shape mostly is small cubes, and inside is vesicular structure, can in actual motion, cover with mud, and form different micropopulations according to the size of carrier, reach the treatment effect of recombining process.Generally speaking, polyurethane foam carrier can form anaerobe layer in carrier inside, realizes the anaerobic treatment of subenvironment; And form larger aerobe layer at carrier surface, realize aerobic treatment; Transition layer can be realized anaerobic environment, carries out anaerobic treatment; Thereby realize the treatment effect that an independent carrier has composite treatment process simultaneously.The problem that existing polyurethane foam carrier exists is: the inner generation mud that is difficult for of polyurethane foam carrier of small-bore, is difficult to realize Pollutants Diffusion and mass transfer; There is the outside not problem of easy to be filmed in wide-aperture polyurethane foam carrier.
Utility model content
The purpose of this utility model is: a kind of Assembled two-layer polyurethane foam carrier is provided, to solve not easy to be filmed of polyurethane foam carrier outside, existing wide aperture, and polyurethane foam inside in small-bore is difficult for generating mud, be difficult to realize the problem of Pollutants Diffusion and mass transfer.
The technical solution of the utility model is: a kind of Assembled two-layer polyurethane foam carrier, comprise that profile is the hard porous polyurethane foam shell of regular cube or rectangular shape, this hard porous polyurethane foam shell center is provided with diameter of Spherical Volume, on one of them surface of this hard porous polyurethane foam shell, offer the passage being communicated with described diameter of Spherical Volume, in described diameter of Spherical Volume, be filled with spherical soft cellular polyurethane foaming lining.
The external diameter of described soft cellular polyurethane foaming lining equates with the internal diameter of described spherical centre hole.
The porous aperture of described hard porous polyurethane foam shell is 2-5mm.
The porous aperture of described soft cellular polyurethane foaming lining is 0.5-2mm.
The length of side of described hard porous polyurethane foam shell is 1.5-8cm.
Double-layer combined polyurethane foam carrier of the present utility model has good permeability and specific surface area, be conducive to the diffusion of dissolved oxygen, ammonia radical ion, nitrate radical etc., be conducive to the biofilm of mud and the formation of anaerobic environment simultaneously, effectively raise biofilm speed and quality, and this double-layer combined polyurethane foam carrier can adsorb mud of different nature in shell and inner bag, make inner mud more easily keep anaerobism, outside mud can keep highly active aerobic sludge, thereby can further improve processing power.
Accompanying drawing explanation
Fig. 1 is the structural representation of the double-layer combined polyurethane foam carrier of the utility model.
Embodiment
The specific embodiment of double-layer combined polyurethane foam carrier of the present utility model as shown in Figure 1, this double-layer combined polyurethane foam carrier comprises that profile is the hard porous polyurethane foam shell 1 of regular cube shape, at the center of hard porous polyurethane foam shell 1, have diameter of Spherical Volume 3, the internal diameter of this diameter of Spherical Volume 3 is less than the length of side of shell 1, on one of them side of shell 1, offer the passage 4 that is communicated with this diameter of Spherical Volume 3, in diameter of Spherical Volume 3, be filled with that external diameter equates with these diameter of Spherical Volume 3 internal diameters spherical soft cellular polyurethane foaming lining 2.Wherein, the length of side of hard porous polyurethane foam shell 1 is 1.5-8cm, and the porous aperture on this hard porous polyurethane foam shell is 2-5mm, and porous aperture on spherical soft cellular polyurethane inner bag 2 is 0.5-2mm.
