Description

The film aerating system biological prosthetic suitable for shallow-layer river
Technical field
The utility model belongs to the quality purifying device for water in environmental project, particularly relates to one kind and is repaiied suitable for shallow-layer river biology Multiple film aerating system.
Background technology
China is more than 50% city river by different degrees of pollution in recent years, river water blackening fouling occurs, wawter bloom is existing As being on the rise.Contaminated river water body is carried out administering reparation being socio-economic development, urban landscape, improvement of the ecological environment There is an urgent need to.
Microbial augmentation purification not only has good treatment effect as one of natural water governing measure to water pollution, There is restoration of the ecosystem important function simultaneously.In microbial augmentation purification into water body aeration aerating to solving the problems, such as black smelly play Key effect, and the coefficient of oxygen utilization of traditional aerator is generally 20% hereinafter, waste a large amount of energy consumption.
Bubble-free aeration membrane-biotechnology (MABR) is a kind of to have merged gas separation membrane technology and biofilm water process skill The Novel sewage treatment technology of art, the hollow fiber ventilated membrane which uses not only had been oxygen supply of water body, but also was used as microorganism The carrier of growth.Its principle is aerated to microorganism and water body using aeration membrane module, and air is after membrane material with molten The form or atomic minute bubbles form for solving diffusion enter water body, since its grain size small area of contact is big, therefore can obtain very high Coefficient of oxygen utilization.Meanwhile hollow-fibre membrane is also good carrier, is very suitable for biomembrane apposition growth, specific surface area can be high Up to 5108 ㎡/m3, prodigious area is provided for microorganism growth in a smaller space, greatly improves the sludge in unit space Concentration.
Oxygen and nutriment are diffused and transmit from different directions respectively in MABR, and oxygen is in hollow-fibre membrane Pressure effect is lower to enter biomembrane through membranous wall, therefore, the concentration highest of oxygen close at membranous wall.And the pollutant in water body is then Transmitted inside from the outer side of biomembrane to biomembrane, with oxygen direction of transfer on the contrary, pollutant concentration on the outside of the biomembrane to interior Portion is in the trend continuously decreased.The life that keep biofilm formation distinctive opposite with traditional biological membrane reactor of above-mentioned mass transfer mode Phase structure, biomembrane are followed successively by anaerobic layer and oxygen layer, aerobic layer from outside to inside.Oxygen and nutriment are in biomembrane both sides It is entered in biomembrane under the effects that concentration difference driving, microorganism adsorption, and by a series of metabolism of organisms and breeding quilt Microorganism utilizes, and so that the pollutant in water body is assimilated into microbial cells and is fixed on biomembrane or is decomposed into simple inorganic generation Thank to product, to be purified to water body.
The characteristics of MABR technologies, determines that it has unique advantage, including oxygen at the biological prosthetic aspect of city river water body Mass transfer rate height, biofilm carrier large specific surface area, can be laid directly in river water body, operating cost is low etc., pass through regulation and control Dissolved oxygen concentration gradient in film surface biomembrane can be effectively controlled, and then obtains the inside and outside special biofilm structure being layered.It should It is emerging technique in recent years that technology, which is applied to city river water body reparation, and still immature at present, main application mode is:Will in The vertical fixing bracket of empty fiber membrane component, which is fixed on metal structure frame, is placed in river bed.Such mode deficiency is:Due to Hollow fiber film assembly is strong buoyancy carrier, in addition water impact acts on, therefore frame must have enough stability, but city The a large amount of sludge of city's bottom of river channel siltation, difficulty of construction are larger, it is difficult to which membrane module frame structure is effectively fixed;The technology is used for river Improvement process cycle in road is longer, and membrane module is completely under the water surface, is not easy to overhaul;And this kind of mounting means be once fixation, no Height can be adjusted according to river water level, flexibility is poor;Most north river especially dry season, available depths are only 0.7-1.0 meters, And generally hollow tunica fibrosa frame structure height is 1.0-1.5 meters, therefore this kind of vertically-mounted mode has certain limitation.
The background technology that applicant is retrieved includes:
A kind of floating type EHBR water bodies of rivers and lakes purifier is disclosed in the patent document of the patent No. 201420006290.6 System, membrane module vertical display, membrane module frame radially, since film itself discharges from height and vertically present situation, are led from inside to outside This kind of frame mode is caused not to be suitable for shallow-layer river, and the water surface area of unit area film wire service is smaller.
A kind of river using artificial aquatic weed formula film wire is disclosed in the patent document of the patent No. 201621028817.0 to control Repair system is managed, film wire fixing bracket, which is fixed on metal structure frame, is placed in river bed, and such metal framework cost is higher, and Difficulty of construction is larger in river, and membrane module height is adjusted according to water level once being fixed from.
A kind of river sewage comprehensive treatment system device is disclosed in the patent document of the patent No. 201320495974.2, Main body is made of highly effective coagulation sedimentation pretreatment unit and reinforcing coupling film bioreactor device.Wherein highly effective coagulation sedimentation system System is positioned over river bank or is assemblied on ship, occupies riverbank or river area, and coagulation need to add a large amount of medicaments, increase fortune Row cost, does not have economic serviceability.
