Description
Technical field
The utility model relates to a kind of Novel immersed membrane bio-reactor assembly, refers in particular to a kind of Novel immersed membrane bio-reactor assembly that relates to sewage treatment area.
Background technology
Membrane bioreactor (MBR) technology is a kind of more advanced sewage recycling technology, according to the difference of membrane module structure, can be divided into flat sheet membrane, hollow-fibre membrane and tubular membrane MBR.Under identical processing requirements, flat sheet membrane membrane module floor space is larger; And hollow-fibre membrane is because upper end is fixed on support, under the state of aeration, film silk is the state in a shake all the time, foreign material easily make film silk be intertwined, when sludge concentration acquires a certain degree, upper end support is easily saved bit by bit mud, not only cause conglomeration fracture, the cleaning difficulty of film silk itself, and the effective filtration area of film declines.
Meanwhile, MBR can, according to the set position difference of membrane module, can be divided into two kinds of immersion and external placed types again.Wherein, immersion type membrane component is that membrane module is positioned over to inside reactor, by the suction function of pump, filters water outlet; The feature of external membrane assembly is that flux is large, and antipollution effect is good, but energy consumption is higher.As the core component of MBR, the design of membrane module is particularly important, and it is directly connected to membrane bioreactor energy consumption size and stain resistance power.
Utility model content
The purpose of this utility model is to provide a kind of compactness rational in infrastructure and the strong Novel immersed membrane bio-reactor assembly of stain resistance.
For reaching above-mentioned purpose, solution of the present utility model is:
A kind of Novel immersed membrane bio-reactor assembly, comprises tubular membrane and housing; Tubular membrane lower ending opening, and be sealedly and fixedly connected on housing, and tubular membrane upper end arranges sealing cap; In housing, be distributed with duct, and on housing, be provided with water outlet.
Further, tubular membrane is by sealing glue, sealing-ring or being fixedly connected on housing with the mode that housing is poured into a mould simultaneously.
Further, tubular membrane is socketed to form by sleeve pipe and film pipe, and the gap between sleeve pipe and film pipe is 1-5mm.
Further, tubular membrane is ultra-filtration membrane (UF) or microfiltration membrane (MF), and fenestra internal diameter is 0.01-0.1 μ m.
Further, tubular membrane adopts external coating (EC), and top layer material is polyvinylidene difluoride (PVDF) (PVDF) or polyethersulfone (PES).
Further, the film bore of tubular membrane is 4-10mm, and component height is 0.5-3m.
Further, housing and sealing cap are engineering plastics ABS, PP, PET or epoxy resin.
Further, hull shape is rectangle, and rectangular housing is long is 400-1000mm, and wide is 100-600mm.
Further, hull shape is circular, and circular shell diameter is 200-600mm.
Further, tubular membrane is evenly distributed on housing.
Adopt after such scheme, when the utility model is used, whole membrane bioreactor assembly is immersed in active sludge, by bottom aerating apparatus, air is squeezed into, mud and air mixture are flowed along top, tubular membrane outside, wash away film tube-surface, reduce the adhesion of film surface mud and pollute, the clear water that simultaneously adopts the methods such as suction that film pipe is seen through outside to inside pumps out from bottom.
The utility model tubular membrane lower end is sealedly and fixedly connected on housing, and tubular membrane upper end arranges sealing cap, and entirety is seaweed type structure, and aeration is upwards gone out, and the sludgd deposition while having avoided top closure has reduced cost and difficulty that follow-up cleaning causes simultaneously.
Tubular membrane is sealedly and fixedly connected on housing, makes the unit membrane area that membrane module contacts with mud be greater than flat sheet membrane, and therefore, less assembly area just can reach larger usable floor area.When reducing floor space, reduced running cost, it is more convenient to safeguard, and stain resistance is strong, energy efficient.

Film pipe 12 housings 2
Embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in detail.
Consult shown in Fig. 1 to Fig. 5, a kind of Novel immersed membrane bio-reactor assembly that the utility model discloses, comprises tubular membrane 1 and housing 2.
As shown in Figure 7, tubular membrane 1 is socketed to form by sleeve pipe 11 and film pipe 12, and the gap between sleeve pipe 11 and film pipe 12 is 1-5mm.The fluid that described inner sleeve 11 structures make to enter in film pipe 12 has fixing rising passway, has effectively solved gas accumulation problems.Housing 2, sealing cap 3 and sleeve pipe 11 are engineering plastics ABS, PP, PET or epoxy resin.
The utility model in use, as shown in Figure 1, is provided with aeration admission passage 10 in housing 2 bottoms.The reactor submergence that MBR membrane module has been assembled is in activated sludge tank/MBR pond 20, by bottom aerating apparatus, air is squeezed into, and mud and air mixture flow along tubular membrane 1 top, outside, and the clear water that simultaneously adopts the methods such as suction that film pipe 12 is seen through outside to inside pumps out from bottom.As shown in Figure 7, membrane-permeable material flows along film inwall, upwards flows out, and after arrival sealing cap 3, flows downward again.Because the bubble that upper end closure enters in pipe can not gather, can along with current from water outlet direction, be sucked out.Thus, solved the accumulation problems of gas in pipe.
The utility model seaweed type tubular membrane component can be assembled into membrane bioreactor, is equipped with kit form and the operational mode of improvement, can be effective, and anti-pollution, the objects such as energy efficient.Membrane bioreactor of the present utility model also can adopt irregular online and off-line matting.
