Abstract

The utility model relates to a napping elastic stereo filling for treating water, wastewater or sewage, which is composed of a centre piece and elastic fibers or strands helically fixed on the centre piece, wherein, the surfaces of the elastic fibers or strands are provided with regular or irregular protuberant condyles, or regular or irregular woolly grains, or irregular longitudinal grooves. The utility model has the advantages of large specific surface area of unit volume, no clogging, no conglomeration, favorable effect of sewage treatment, etc., the speed of initial film formation is accelerated, and the biomass during operation is increased.

Description

The plucking elastic solid filler

The utility model relates to the biologic packing material that a kind of water, waste water or sewage disposal are used, and specifically refers to a kind of plucking elastic solid filler.

Biomembrance process is to be microbe carrier, the maturation process of removing organic pollutant in the waste water with the filler, is used widely in engineering of water treatment.

Biologic packing material is as microorganism carrier, the quality of its performance, the effect of water treatment had very important influence.Early stage filler mainly is a honeycomb class filler, and cost height and specific surface area are little, easily stops up.The early eighties soft-filler comes out, and it is big that it has specific surface area, the advantage that biofilm is easy, cost is low, but easy conglomeration and work-ing life are short.Subsequently, combined stuffing listing of new generation, it prevents that the conglomeration aspect from having than much progress, but because polyvinyl is too thin, the problem that lack its work-ing life is still unresolved, and cost significantly raises.

The early 1990s, succeeding in developing of elastic solid filler, this filler selection is suitable, novel structure, corrosion-resistant, ageing-resistant is difficult for obstruction, balling, and microbial film easily upgrades, and, since microbial film be evenly distributed and filling fibers to the repeatedly cutting of rising bubble, improved coefficient of oxygen utilization, long service life.Elastic filler is well received with its good performance.But the present smooth surface of the elastic filler of using, though have stamp simple rule or irregular impression (ripple) on the surface, as Chinese patent " biological adaptive color elastic corrugated 3-D filler ", its notification number is CN2248709Y.It totally is still slick, and the microorganism initial stage is adhered to difficulty, so the relative soft-filler of biofilm speed or combined stuffing are slower.

The purpose of this utility model is to provide that a kind of adaptability is strong, the utiliztion ratio surface-area big, the microorganism initial stage adheres to speed plucking elastic solid filler faster.

The purpose of this utility model takes following measure to realize: the utility model is made up of centrepiece and spandex fiber or the strand fixed on it, described spandex fiber or strand spirrillum are fixed on the centrepiece, the apophysis of the surperficial regular or irregular protuberance of spandex fiber or strand, (or) regular or irregular burr and (or) irregular longitudinal fluting arranged.Specific surface area with the raising filler is that microorganic adhesion creates favorable conditions also, thereby has accelerated biofilm speed, improves the effect of wastewater treatment on the whole.

Embodiment elaborates to the utility model below in conjunction with accompanying drawing:

Fig. 1 is a plan structure synoptic diagram of the present utility model

Fig. 2 is a main TV structure synoptic diagram of the present utility model

Fig. 3 is the structure for amplifying synoptic diagram of elastic yarn embodiment of the present utility model

Among the figure: 1. axial cord 2. elastic yarns 3. apophysis 4. burrs 5. grooves

According to Fig. 1, Fig. 2, embodiment shown in Figure 3: the utility model is made up of axial cord 1, elastic yarn (spandex fiber or strand) 2.Elastic yarn 2 spirrillums are fixed on the axial cord 1.Surperficial regular or irregular apophysis 3 protuberances of elastic yarn 1, the surperficial regular or irregular burr 4 of elastic yarn 1, there is irregular longitudinal fluting 5 on the surface of elastic yarn 2.

Structural design of the present utility model compared with prior art has outstanding advantage: adopt Use special process, make the filling fibers surface form apophysis, burr or longitudinal fluting, surface galling Behind the filler, improved the specific area of filling fibers, simultaneously, for providing good adhering to of microorganism Habitat condition, also corresponding increase of biofilm biomass in the unit volume, thus accelerated the initial stage biofilm Speed and run duration biomass are conducive to improve whole wastewater treatment efficiency. Plucking elasticity is vertical The body biofilm and upgrade fast, unit volume biomass greatly, do not stop up, not conglomeration. And make Long with the life-span, be conducive to improve water treatment efficiency, can be widely used in all kinds of waste water, sewage And in the little pollution pretreating process in water source and the device.

Claims

A kind of by centrepiece with fix spandex fiber on it or plucking elastic solid filler that strand is formed, it is characterized in that described spandex fiber or strand spirrillum are fixed on the centrepiece, the apophysis of the surperficial regular or irregular protuberance of elastic yarn, (or) regular or irregular burr and (or) irregular longitudinal fluting arranged.
