Abstract
The invention relates to a curtain-type film assembly used in flim bioreactor. In order to settle present problem in technology, the invention provides a curtain-type film assembly, and comprises hollow fiber microporous membrane thread and collecting tube, which is characterized in that the hollow fiber flim is in 'U' shape, with open end connected with upper collecting tube, the lower of U-shape is free end, between lower membrane threads slotting tube is located, which is thinner than collecting tube and taken as inset tube. Inset tube connected with aerated conduit and perforated-up. Inset tube and lower aerated conduit forming a closed tube circuit, the lower of membrane threadn is in the circuit. The curtain-type film assembly supported by the invention has the following merits: no-contamination, no activated sludge between membrane thread, convenience on cleaning membrane thread, and it can improve dewatering efficiency of film assembly.
Description
Technical field
The present invention relates to a kind of membrane bioreactor (MBR), the used curtain type film assembly of particularly a kind of membrane bioreactor.
Background technology
Membrane module of the prior art as shown in Figure 1, upper and lower end parts has upper set pipe 1, following collecting tubule 4 respectively.The two ends of hollow-fibre membrane silk 2 are bonded on the collecting tubule respectively.In the use, curtain type film assembly is vertically fixed in the reaction tank, and the active sludge of system (microorganism) is easy to accumulate in the junction surface of bottom collecting tubule 4 and tubular fibre 2 in the operational process.Reference numeral 3 among Fig. 1 has shown the position that active sludge stops.Accumulate the mud that gets off and be difficult to wash, can cause the severe contamination on film surface, even curtain type membrane lower film silk connected together by active sludge, influence its water outlet effect.
Therefore, there is defective in the prior art, has further improved necessity.
Summary of the invention
For solving problems of the prior art, the invention provides a kind of curtain type film assembly, comprise hollow-fibre membrane silk and collecting tubule, it is characterized in that: hollow fiber microporous membrane is " U " type form, opening end is bonded on the collecting tubule of top, and the lower end of U type silk is a free end.
According to curtain type film assembly of the present invention, it is characterized in that: the position, space between the lower films silk of U type install additional one than the thin perforated pipe of upper set pipe as tubular stinger.
According to curtain type film assembly of the present invention, it is characterized in that: tubular stinger links to each other with aeration tube, and perforate up.
According to curtain type film assembly of the present invention, it is characterized in that: the aperture of perforated pipe and hole count all are less than the aperture and the hole count of aeration tube.
According to curtain type film assembly of the present invention, it is characterized in that: tubular stinger is connected by union with following aeration tube.
According to curtain type film assembly of the present invention, it is characterized in that: tubular stinger is formed closed pipeline with following aeration tube, and the bottom of film silk is contained in the closed pipeline.
Because hollow-fibre membrane of the present invention is " U " type form, opening end is bonded on the collecting tubule of top, the lower end of U type silk is a free end, therefore in the MBR pond, because the bottom aeration tube constantly is blown into air, the bubble of rising makes the shake of film silk, and bubble and membranous wall friction take place and active sludge is difficult to attached on the film surface, and because the lower end is a free end, Gu can not accumulate mud.Thereby curtain type film assembly provided by the invention has and be difficult for to pollute, does not accumulate active sludge between the film silk, cleans the advantage that the film silk is convenient, improve membrane module water outlet efficient.

Fig. 3 is a U type silk curtain type film assembly shake synoptic diagram of the present invention;
Fig. 4 is an intubate and following aeration tube connection diagram under the present invention.
Embodiment
The present invention adopts hollow fiber microporous membrane 5 with " U " type form, and its opening end is bonded on the upper set pipe 1, and the lower end is the articulation set pipe not.Install a perforated pipe thinner additional than upper set pipe at the position, space of U type, as following tubular stinger 6, tubular stinger 6 links to each other with aeration tube 8, and the aperture of tubular stinger 6 and hole count all are less than the aperture and the hole count of aeration tube 8, and perforate up, and the bubble of release directly blows the space of tubular fibre.Because this root gas blow pipe directly is not connected with silk, can pull down, so the lower end of U type silk 5 is free ends, the active sludge that hangs up can be got off by purge or rinsing at an easy rate.Because the little tubular stinger 6 of this root is the lower space of passing this row U type cortina, it also plays localized effect, makes these U type silks can be not at random because of the bottom aeration in the MBR reactor.
As an example, upper set pipe DN25, following intubate DN15, the solarization air cap that one aperture, 3～4mm is arranged every 20mm～30mm on back medullary ray on tubular stinger 6 edges, following intubate 6 makes silk that certain freeboard be arranged, when descending aeration tube 8 aerations like this apart from the about 10mm～20mm in U type bottom of U type silk, as shown in Figure 3, silk can certain space up and down and left and right directions shake.Tubular stinger is connected and can removes by union with following aeration tube.Because tubular stinger and following aeration tube are formed closed pipeline, be " ∏ " type and connect, the bottom of film silk holds and is limited in the closed pipeline, and is unlikelyly dispelled unrest because of the aeration quilt.U type filament length 1.5m, the wide 0.5m of upper set pipe, full wafer curtain type membrane area 20m
