Method.
Background technique
Aerobic particle mud (aerobic granular sludge, AGS) is microorganism under environmental condition appropriate,
A kind of granular agglomerate activated sludge formed by spontaneous cohesion.Compared with ordinary activated sludge, aerobic particle mud tool
Have structure is closely knit, settling property is good, biofacies is high, metabolic activity is good, capacity of resisting impact load is strong, be not susceptible to sludge bulking with
And the advantages that poisonous and harmful substance effect is good is removed, therefore always by the extensive concern of lot of domestic and foreign scholar.However, particle
The culturing sludge period takes long time, and needs to undergo 1~2 month or so time mostly from sludge acclimatization to particle maturation, and
Phenomena such as granule sludge after maturation is unable to maintain that operation steady in a long-term, is easy to appear disintegration, settling property variation, thus limits
Popularization and industrialization of the aerobic particle mud in actual industrial waste water treatment applications.Therefore, how sludge is fast implemented
Granulation, maintaining long-time steady operation to make aerobic particle mud, large-scale promotion and application are urgently to be resolved in practical projects
Critical issue.
It is that one kind more has by the fast culture that outside adds molecule as nucleus to realize aerobic particle mud
The solution of effect.The formation mechenism of this method is based on induced nuclei hypothesis, it considers that the formation of aerobic particle mud is one
The process of the similar crystallization of kind, first has to place of the nucleus as germs collect and apposition growth, microorganism is in nucleus
Upper attachment, constantly aggregation growth, partial size become larger, until forming mature granule sludge.The presence of induced nuclei can be with
The progress for accelerating sludge aerobic granulating, saves the short grained formation time.Common adds the active charcoal of nucleus particle, stone
The inorganic particulate matters such as ash, crystal micro-powder and aerobic/anaerobic granule sludge etc..However, promoting using mycelium pellet as nucleus aerobic
The correlative study of granular sludge is at present both at home and abroad there is not yet report.
Mycelium pellet is that one kind that shaken cultivation, automatic aggregation are formed under the conditions of liquid floods by mould or actinomyces had both had
There is vital signs, and has the spherical particle object of absorption and carrier characteristics.Due to the composition of mycelium pellet inherently microbial cells
Part has preferable hydrophobe equilibrium valve；And mycelia secretion extracellular polymeric and its surface existing for electrostatic attraction, function
Group or element etc. are all conducive to the adherency to other microbial cells, and distinctive meshy surface structure is also beneficial to microorganism
It inhabites and breeds, therefore be conducive to sludge attachment fixation and form mud granule.It theoretically analyzes, mycelium pellet is added to activity
In sludge, induced nuclei can be formed, space surface is provided for the mutual Absorption Growth of microorganism, microbial is promoted mutually to assemble shape
At granule sludge, and the physical strength that mud granule will be greatly increased, show superior physical characteristic.
Therefore, the present invention is based on " the induced nuclei hypothesis " of aerobic particle mud, mycelium pellet is added as induced nuclei, is added
The granulating of fast aerobic sludge, to be Aerobic Granular Sludge Technology in Industrial Wastewater Treatment practical application play it is positive
Impetus.
