Abstract

Be used for realizing the utility model discloses a tow for bearing weight of microorganism of purpose, its characterized in that, institute's tow of saying by the coiling of fibre long filament circlewise or the both ends ligature become the fasciculation. Be used for realizing the utility model discloses the another kind of a tow for bearing weight of microorganism of purpose, its characterized in that, the line made by fibre short silk or fibre long filament of the tow of saying or rope or strip coiling circlewise or both ends ligature fasciculation. The utility model provides a pair of the filtering layer that a tow for bearing weight of microorganism constituted has the characteristics of specific surface big (being greater than 6000 square metres of / cubic metre filtering layers) and porosity high (about 90%), and microorganism unit's bearing capacity can reach several times of the graininess filter material to can show improvement pollutant volumetric loading and hydraulic load.

Description

For the fibrous bundle of bearing microorganism

Technical field

The utility model relates to microbial process and the filler of water treatment and gas disposal.

Background technology

The filler that the biological filter of existing sewage disposal and off gas treatment is used for bearing microorganism is generally particulate state or bulk, as haydite, volcanics, light plastic particle, polyurethane sponge block etc.The shortcomings such as these packing specific areas are smaller, porosity is lower, the easy blocking of packing layer (filter material layer).

Summary of the invention

The purpose of this utility model is to provide the fibrous bundle for bearing microorganism.

For realizing a kind of fibrous bundle for bearing microorganism of the utility model object, said fibrous bundle turns to ring-type or two ends colligation fasciculation by fiber filament.

For realizing the fibrous bundle of another kind for bearing microorganism of the utility model object, the line that said fibrous bundle is made up of short fibre or fiber filament or rope or band turn to ring-type or two ends colligation pencil.

Said fibrous bundle is formed by connecting by rope or web member by more than two sections and two sections fibrous bundles.

The cross section of said short fibre or fiber filament is circular or oval or cashew nut shape or trilateral or pentagon or square or prismatic or Y shape.

The outside surface of said short fibre or fiber filament is smooth or coarse fluted pertusate or bossed.

Some said fibrous bundle two ends are suspended on respectively on two upholders and form filtering layer; Some said fibrous bundle upper ends are suspended on upholder upper and lower ends and hang heavily pendant formation filtering layer; Some said fibrous bundle lower ends hang upper end on a support and hang float formation filtering layer.

Said filtering layer is arranged in housing and forms biological filter or biofilter, arranges aerating apparatus and cleaning air distributing device in said filtering layer bottom.

Fiber cross section makes non-circular and surface irregularity can significantly improve specific surface area, thus improves microorganism bearing capacity, can retain more microbial biomasss after cleaning simultaneously.

Load different microorganisms at fibrous bundle filling surface and just become the degraded BAF of COD, the BAF of degradation of ammonia nitrogen, the denitrification filter pool of degrade nitrate nitrogen, the degraded deodorizing filter chamber of foul smell, the biological filter etc. of other material of degrading.

A kind of filtering layer formed for the fibrous bundle of bearing microorganism provided by the invention has the feature of specific surface area large (being greater than 6000 metre squared per cubic filtering layers) and porosity high (about 90%), microorganism unit bearing capacity can reach the several times of granular filter material, thus can significantly improve pollutent volumetric loading and hydraulic load.

Embodiment

The fibrous bundle schematic diagram for bearing microorganism of Fig. 1 coiling

Fig. 2 multistage is used for the fibrous bundle schematic diagram of bearing microorganism

The fibrous bundle schematic diagram for bearing microorganism of Fig. 3 colligation

The some fibrous bundles for bearing microorganism of Fig. 4 hang and form filtering layer schematic diagram

The present invention is described in detail below in conjunction with accompanying drawing.

Figure 1 shows that the fibrous bundle 1 for bearing microorganism being coiled into flat ring-type with fiber filament;

Figure 2 shows that the fibrous bundle for bearing microorganism is formed by connecting by rope 2 by the flat fibrae circulares bundle 1 of multistage.

Figure 3 shows that with the fibrous bundle 7 for bearing microorganism of fiber filament by binding piece 3 colligation;

The two ends of some fibrous bundles 1 for bearing microorganism are suspended on respectively by web member 4 shown in Fig. 4 and support member 5 and lower support element 6 form filtering layer above.Before work, the microbial inoculant of certain function is loaded on fibrous bundle 1, needs water to be processed or air or other fluid to be processed by filtering layer from bottom to top from top to bottom or or from left to right.When needing oxygenic aeration by air by being arranged on filtering layer bottom or filtering layer sent into by middle part aerating apparatus.Need, during cleaning, air is sent into filtering layer by being arranged on filtering layer bottom cleaning air distributing device.
