Description
Technical field
The present invention relates to technical field of waste water processing, specifically a kind of high concentration lint wastewater treatment equipment and method.
Background technology
High concentration lint waste water treatment is started to walk more early in China.In early 1970s, units concerned have carried out height
Concentration lint waste water treatment research work.After the mid-80, Treatment process enters a new developmental research period, and takes
Obtained many new scientific achievements, such as biological contact oxidization treatment technique, application of anaerobism (hydrolysis) aerobic treatment process etc..
And there is the desized wastewater of high concentration due to which in high concentration lint waste water so as to the spy for being different from other textile printing and dyeing wastewaters
Point.High concentration lint waste water quality is because the water yield is big, colourity is big compared with deep, change of water quality, content of organics is high or even contains a certain amount of
Noxious material, and become that contamination hazard is big, one of intractable industrial wastewater.In recent years, fast with textile and dyeing industry
Speed development, environmental protection, pollution control are increasingly taken seriously.Although high concentration lint wastewater treatment in the scale with municipal sewage at
Reason factory has a long way to go, more increasingly complex than municipal sewage in draining water quality.Great majority still fall within organic contamination category.High at present
Concentration lint waste water treatment process always is very scabrous problem.Past high concentration lint waste water is sent out through preliminary sedimentation tank and anaerobism
Ferment preliminary treatment, although have certain removal to act on to suspension lint material, but BOD5Clearance is very low, and does not possess denitrogenation and remove
Phosphorus function, it is impossible to meet water prevention and cure of pollution and the requirement of water environment protection.In recent years, it is adaptable to high concentration lint waste water small-sized
The technological development of Sewage Disposal and sewage disposal device quickly grows.The change of high concentration lint wastewater processing technology, experience
From single technique to the process of group technology.From whether aerobic angle is investigated, then along " anaerobism → aerobic → anaerobism+good
The track development of oxygen → anaerobe-oxygen deficient ".From the point of view of object is removed, past high concentration lint waste water is by hydrolytic tank only to suspending
Material has carried out preliminary treatment, and these can not meet environment protection emission requirement, it is necessary to existing high concentration lint wastewater treatment side
Method is improved.Several high concentration lint waste water treatment process conventional at present and equipment is described below.
1st, biological contact oxidation process
Biological contact oxidation process, is a kind of Sewage Biological Treatment skill between activated sludge process and biofilter between the two
Art, has both both advantages.Its main units is biological contact oxidation pond, fills filler, the sewage leaching of oxygenation in pond
Inwhole fillers, and flowed through by the filler of its submergence with certain flow velocity, biomembrane is formed on filler, sewage is wide with biomembrane
General contact, on the biomembrane in the presence of the metabolic function of microorganism, dirty organic pollutants are removed, and sewage is obtained
To purification.Due to possessing the good environment condition for being suitable to that microorganism perches propagation in pond, therefore, on biomembrane microbial when rich
Richness, food chain length, microorganism concn are high, activity is strong, do not produce sludge bulking, and sludge creation amount is few, and is easy to precipitation.Biology connects
Tactile oxidizing process has multiple purification functions, in addition to effectively organics removal, such as runs proper, additionally it is possible to deoxidation and dephosphorization.Raw
The key position of thing contact oxidation method is filler.Traditional honeycombed plastic pipe is easier to blocking, now soft frequently with suspension type
Filler and suspension or half suspension Ball-type packing, can be effectively prevented blocking, and area is larger, high treating effect.Biological contact oxidation
Change method is one of technology that residential quarters sanitary sewage disposal is more early adopted.
2nd, two sections of activated sludge processes
Two sections of activated sludge processes, abbreviation AB method, is the abbreviation of adsorption biodegradation.The method is sewage conduct, dirt
Water treatment plant is considered as a sewage disposal system.Its process characteristic is：Just shallow lake pond, A section high load capacity, B section underload, A, B are not set
Two sections of sludge are flowed back respectively, make full use of the microorganism in sewage conduct, are the superior microorganism population wound of different times growth
Good environmental condition is made, allows which to play one's part to the full, anti impulsion load ability is strong, and treatment effect is stable.Its main process stream
Cheng Wei：The kind equipment, using Self-priming jet aeration machine, unsupported sludge suspension type biologic packing material, lateral flow domatic swash plate
The advanced technologies such as sedimentation basin.BOD5It is 80% that clearance is 90%, COD clearance.
3rd, anaerobic biofilter
Anaerobic biofilter is that a kind of inside is equipped with filler as the anaerobic organism embrane method processing meanss of microbe carrier.Detest
The superficial growth of oxygen animalcule attachment carrier, when the fixed bed consisted of carrier from bottom to top by sewage, micro- in anaerobism
Under biological agent, the organic matter in sewage is able to anaerobic digestion, and produces biogas.Anaerobic biofilter has multiple modifications, filler
Quickly grow, its technological process is：Water inlet → sedimentation basin → anaerobic digester → anaerobic biofilter → pull out airduct → oxidation
Ditch → air inlet wet well → draining, sewage enter anaerobic digester after sedimentation basin pretreatment and are hydrolyzed and are acidified, and can improve
The biodegradability of sewage, is that subsequent treatment creates conditions.Under ventilating system effect, biofilter is in anaerobic state, prevents
In sewage, the generation of methane bacteria, makes whole system still in acidic phase, and dissolved oxygen can typically be stablized in oxidation ditch
1.5 2.8mg/L, the further Aerobic Process for Treatment of sewage here.Its major advantage be do not consume energy, low cost, management is simple, no make an uproar
Sound, free from extraneous odour, biofilm are fast, surplus sludge volume is few, effluent quality is good, operational effect is stable.High concentration lint waste water is processed with regard to which
For technology, can be using the mature technology of current municipal sewage treatment and technique, but high concentration lint treatment of dyeing wastewater has
The feature of its own, should consider.
According to narration above, it can be appreciated that although high concentration lint waste water treatment process develops till now
Comparative maturity, but on this field of high concentration lint wastewater treatment, a lot of problems are still suffered from, only lean on single handling process
Be it is difficult to make water outlet qualified discharge, it is necessary to existing technique is carried out integrated, using the method for kinds of processes Combined Treatment,
Energy qualified discharge, even turns waste into wealth, realizes the purpose of comprehensive utilization of resources.If having grasped above technology, high concentration hair
Suede waste water can just find a kind of real process is simple, easy to operate, process thoroughly, save energy and process side with low cost
Method.
