Description
Technical field
The invention belongs to the technical field of sewage in environmental project, it is related to a kind of coagulation-anaerobic hydrolysis-aerobic collaboration
The device and method of processing cutting liquid waste water.
Background technology
Cutting fluid is that for the working fluid for cooling down and lubricating in process of metal working, its species is various, complicated component.Cut
The common feature for cutting liquid waste water is oil content big and with great stability, and content of organics is high, poor (the i.e. hardly possible of biodegradability
Biochemical degradation).The conventional processing method of Cutting Liquid Wastewater has physicochemical treatment method, advanced oxidation processes, biochemical process etc. several
Major class.
(1) physical-chemical process
During processing cutting liquid waste water, what is used in physicochemical treatment method has absorption method, membrane separation process, Bubble-floating Method, acid out
Method, salting out method, Coagulation Method etc..
Absorption method is colloidal particles, suspended organic matter and micro- life in the hole Adsorption water using porosu solid material
The method of the polluters such as thing.The active charcoal of conventional adsorbent and macroporous absorbent resin etc..Activated carbon price is higher, and absorption
Finite capacity can improve processing cost, it is necessary to often change using activated carbon, therefore generally only in relatively low useless for the treatment of oil content
Water is used in advanced treating.Absorption method occupation area of equipment is small, high treating effect, but costly, and adsorbent reactivation is stranded
It is difficult.
Membrane separation process is to intercept polluter using filter membrane, so that waste water is purified.But the method is to waste water
Pretreatment has relatively is strict with, to avoid film from quickly polluting, so as to extend the use time of film.Membrane processing method investment cost compared with
Height, operational administrative level requirement is stricter, there are problems that, and the cleaning of film is bothered, sometimes the organic matter of filtrate
Concentration is still higher, subsequently needs to carry out biochemical treatment, and processing cost is higher.
Bubble-floating Method refers to the pollutant containing hydrophobic group in the micro-bubble adhesion waste water using high degree of dispersion so that stingy
Bubble and pollutant are combined into an entirety of the density less than water, so as to above bubble through the water column and remove.Can be by dosing coagulant etc.
Measure improves air flotation effect, and discharge can be realized for content of organics wastewater fraction not high, but majority is stilled need further
Advanced treating.The wastewater flow rate of Bubble-floating Method treatment is big, will not produce waste residue waste gas, but Bubble-floating Method floor space is big, energy consumption is higher.
Acid-precipitation method is that in acid condition, solubilised state or colloidal attitude oily substance are converted into suspended state, so as to by oils thing
The method that matter etc. is separated from liquid, such method is simple to operate, and medicament used is generally the highly acids such as the concentrated sulfuric acid, nitric acid
Material, it is also possible to which acid pickle replaces pure acid reagent, but the sediment or scum silica frost of the method generation are more, and requires that equipment has
There is certain corrosion resistance.
Salting out method be to adding inorganic salts material to finite concentration in waste water, destroying the hydration shell of oil droplet, it is general conventional
Electrolyte has calcium chloride, magnesium chloride, sodium chloride, calcium sulfate, alum etc..But the usual effect of salting out method is not so good as acid-precipitation method, and
It is expensive and a large amount of sludge settlings can be brought and salting out method added amount of chemical is larger, brought compared with burden to treatment.
Coagulation Method is to dosing coagulant in waste water, is caught using the net of coagulant, the effect such as adsorption bridging, makes particulate oil droplet
Mutually coalescence becomes big, as larger aggregate, then the separation and removal that solid-liquid is realized by other conventional methods.Coagulant has
Inorganic coagulant, organic coagulants and microorganism coagulant three major types.Inorganic coagulant it is most commonly used be aluminium salt, molysite
It is the aluminium polychloride (PAC) that is developed with calcium chloride and improving on this basis, poly-ferric chloride, PAFC, poly-
The inorganic polymer coagulants such as aluminium iron silicate.Organic coagulants species is more, and being generally divided into natural organic coagulants and synthesis has
The major class of machine coagulant two.Divide from structure, then have anionic, cationic and nonionic three major types.Microorganism coagulation
Agent is a kind of novel coagulant, is the metabolite produced by microorganism or its secretion, and it has easy separation of solid and liquid, shape
Into precipitation and mud amount it is less, easily reacted by own metabolism by microorganism and degraded, non-toxic, non-secondary pollution.Due to not
Prepared by the microorganism coagulant of same type need different conditions, and influence factor is more, such as the carbon source of culture medium, nitrogen source,
Cultivation temperature, pH value etc., so current microorganism coagulant is too high because of its production cost, extensive use are not able to also.
(2) advanced oxidation processes
Advanced oxidation processes generally comprise ozone oxidation, Fenton reagent method etc..Advanced oxidation processes most outstanding feature is system
The hydroxyl radical free radical of higher concentration can be produced, hydroxyl radical free radical oxidation-reduction potential is very high, can be sent out with most organic matters
Raw redox reaction, by complicated chain reaction and the change of redox price, makes organic matter finally be degraded to dioxy
Change the small-molecule substances such as carbon and water, it is so as to reach the purpose of exhaustive oxidation organic matter and environment friendly and pollution-free.But ozone oxidation
Ozone adds low with haptoreaction system effectiveness in method, therefore ozone dosage is big, and the device consumption of electric energy for preparing ozone is high,
Cost is high, applies be restricted in this way.Hydrogen peroxide (the H used in Fenton reagent method2O2) application cost is higher, because
This application is also restricted.
(3) biological treatment
Biological treatment is the processing method using polluters such as the organic matters in microbial degradation removal waste water, due to
What the removal of polluter was utilized is the biochemical reaction of generation in microbial life active procedure, so being frequently referred to biochemistry again
Method.It is different for the demand of oxygen according to microorganism during biological wastewater treatment, bioanalysis is divided into Aerobic biological process method,
Anaerobic biotreatment method.
(1) Aerobic biological process method, is that the enough oxygen of microorganism is supplied in processing procedure, will using aerobic microbiological
Oxidation operation is decomposed, and is eventually converted into CO2And water.The main active sludge of aerobic biological treatment process and biomembrance process
(such as biofilter, biological rotating disk, bio-contact oxidation, biological fluidized bed).Wastewater treatment of the method for easily biological-degradable
Effect is good, but energy consumption is big, and excess sludge treatment, disposal are more difficult.
(2) Anaerobic biotreatment method, is that oxygen is not supplied in processing procedure, using anaerobe by having in waste water
Machine thing changes into the gases such as methane and carbon dioxide.The anaerobic biodegradation process of larger molecular organicses can be divided into three ranks
Section：The hydrolysis acidification stage, (under hydrolysis and zymogenous bacteria effect, larger molecular organicses were converted to monose, amino acid, fat
Acid, glycerine etc.), the hydrogenesis and acetogenesis stage (in the presence of hydrogen-producing acetogens, the product of first stage is changed into hydrogen, two
Carbonoxide and acetic acid) and the methane phase stage (in the presence of methanogen, the product of second stage is changed into the gas such as methane
Body).The methane that Anaerobic treatment technique is produced as reusing of energy source, can produce the amount of excess sludge less.But by
It is slower in anaerobic bacteria growth and breeding and sensitive to radioactive substance, there are strict demand, therefore anaerobic bio-treated to living environment
Process is higher to operational management requirement, the strict control of service condition requirement, otherwise easily causes anaerobic system to collapse.
