Shown in Figure 1 be respectively α-, β-, the structural formula of γ-Huan Hujing.
The detailed description of invention
The inventor finds through deep research, utilizes the natural microbial mixed liquor to cooperate starch to derive Cyclodextrin in the thing can be processed the harmful chemical in effluent sewage and/or the waste sludge effectively. This Bright processing method has economy, easily use, effective characteristics. The present invention just is being based on above-mentioned Existing finishing.
The invention provides a kind of method of processing effluent sewage or waste sludge mixture, this effluent sewage or useless dirty Can contain phenol chemical substance or metal ion in the mud mixture, or the phenol metallic compound; Its bag Draw together the following step:
(a) add an amount of cyclodextrin, and through the mix and blend of appropriateness and the incorporation time that needs;
(b) add again suitable microorganism, through the reaction time that needs, to decompose this phenol chemicals This metallics of matter or oxidation.
According to the present invention, used cyclodextrin can for α-, β-, gamma-cyclodextrin and composition thereof, The preferred beta-schardinger dextrin-that uses. But according to the size of the pending size of chemical substance own, can use The cyclodextrin of big or reduced size. These cyclodextrin for example can be from Cerestar USA, and Inc. purchases .
Cyclodextrin is the combination of starch chain molecule. Common cyclodextrin is to utilize ferment in conjunction with 6,7 Individual or 8 circuluses that glucose molecule forms, generally also be commonly called as α-, β-, gamma-cyclodextrin, Molecular structural formula is listed in Fig. 1. The Stability Analysis of Structures of cyclodextrin own, and can antiacid alkali, the ring-type of its hollow Structure makes cyclodextrin use the special physics and chemistry character of generation.
The addition of cyclodextrin can be decided according to the amount of harmful substance pending in the waste water. Usually, The amount of cyclodextrin is 1-15 times of nuisance quality, preferred 2-10 times, and more preferably 3-7 times, Such as 5 times. For example, sewage contains the benzene class material of 20ppm, then adds 100ppm's in sewage Cyclodextrin. Preferably, the amount of cyclodextrin is more excessive than the amount of harmful substance, to increase cyclodextrin and nuisance The bonder meeting of matter such as benzene class. According to the actual requirement of wastewater treatment, for example according to certain waste water row Put standard, also can use the cyclodextrin that lacks than the nuisance quality.
According to the present invention, after cyclodextrin being added pending effluent sewage or greasy dirt muddy water, in addition constantly appropriateness stirs, like this cyclodextrin have an opportunity by fluidic flow with pending liquid in the phenol chemical molecular, long chain hydrocarbon, the contact of objectionable impuritiess such as phenol metallic compound.The speed that stirs does not need very strict, as long as it is bonding with objectionable impurities such as phenol type substances to allow cyclodextrin have an opportunity.Stirring can be continuity or discontinuity, but does not need special stirring fast.The mode that stirs can be stirred by machine mixer, or utilizes circulation to help to keep the circulation back and forth of wastewater stream.
When cyclodextrin and these chemical moleculars contact,, will produce adhesive effect via the intermolecular power of attracting each other.Because the hollow structure size of cyclodextrin is fit to the structure size of phenol molecule, and very high probability is arranged, these chemical moleculars are placed in the hollow structure of cyclodextrin.When these chemical moleculars were surrounded by the cyclodextrin molecular of periphery, the chemical property of original phenol also had no way of being revealed in the waste water, and whole adherent molecule becomes the indifferent equilibrium material.Through special chemical substance such as the polychlorobiphenyl in the effect sign waste water of cyclodextrin, the chemical molecular of Polyphenols, thus it is decomposed easily effectively.
For the long chain molecule of some polyphenyl classes,, can't be enclosed within the cyclodextrin because this body structure of molecule is bigger.But because the intermolecular power of attracting each other has two or more cyclodextrin and is attached on the long chain molecule.Several cyclodextrin are attached to long-chain polyphenyl molecule can many different geometric spaces combinations, according to cyclodextrin institute arrange and decide in long-chain polyphenyl molecular combinations spatial, long-chain polyphenyl molecule may or can not manifest its original chemical property.As for the heavy metal that contains in the waste water, phenol metallic compound particularly, also via the adhesive ability of cyclodextrin, be attached to the inside or the outside sidepiece of cyclodextrin, viewpoint with whole macroscopic statistics, harmful chemical property in the whole liquid reduces a lot of via the effect of cyclodextrin, and cyclodextrin has marked effect in fluid, allows microorganism look for the target of wanting disaggregating treatment easily.That is to say that cyclodextrin can be stabilized the harmful chemical in the effluent sewage, and have marked effect, can change the effluent sewage ecotope that original microorganism can't survive or breed.
The time that mixes of cyclodextrin and waste water is neither be very strict, and the amount of the cyclodextrin of this and the speed that stirs, sewage quantity, adding etc. are relevant, and needing only cyclodextrin and pending material can be bonding basically.For example, for 500 or 1000 milliliters laboratory measuring cup, stir and got final product as 5-10 minute in 2-15 minute, and for large-scale operation, churning time can be elongated, as 15-30 minute, or longer as 45-60 minute.
The temperature of reaction of above-mentioned steps (a) can be the temperature of carrying out wastewater treatment usually, as under the waste water envrionment temperature, and for example 0-85 ℃, preferred 5-70 ℃, more preferably 10-60 ℃.
The waste water that adds cyclodextrin stirs through suitably mixing, and adds an amount of microorganism slowly.
According to the present invention, employed microorganism can be the microorganism of any capable decomposition cyclodextrin.Because cyclodextrin is by the starch preparation, and starch itself is the combination of glucose, therefore, the microorganism of the decomposition cyclodextrin of having the ability is a lot.These microorganisms can comprise the happy expression bacterium, hold concurrently gas bacterium, order of succession and some natural gill fungus algae.In the method for the invention, the preferred main bacterial classification that adopts can have genus bacillus (Bacillus), pseudomonas (Pseudomonas), fixed nitrogen spirobacteria (Azospirillus), root nodule bacterium (Rhizodium), fixed nitrogen bacillus (Azotobacter), soil is propagated cyanobacteria (SoilborneCyanobacteria) etc., and each single bacterial classification all is available commercially.Single microbial strains out of the ordinary can't provide complete wastewater treatment, the mixture of two kinds of therefore preferred uses or multiple microorganism, and its ratio does not have special requirement yet.Selecting the most important condition of microorganism is not contain the germ that makes the people sick in the microorganism, and blended bacterial classification in the microorganism concentrated solution, must can keep the microorganism eubiosis to each other.The microorganism concentrated solution is preferably based on natural microbial.The used microbial mixture of the present invention for example can be from Advanced Concept Thermal System, and Inc.U.S.A. buys with trade(brand)name Super Max.If microbial mixture is difficult for buying, the first ectogenesis in the glucose nutritive medium separately of various microorganisms can be got final product on a rough average the mixing of several microorganisms then.
Among the present invention, the microorganism add-on can change as required, and this depends on the amount of for example kind, waste water and the cyclodextrin of microorganism, desirable processing speed etc.The amount of microorganism is that every milliliter of waste water contains several thousand or several ten thousand microorganisms, for example 10,000 to 500,000, and ten thousand of preferred 5-30.The amount of microorganism is not strictness, after for example adding nutritive substance, can accelerate the breeding of microorganism, therefore can add a spot of microorganism, perhaps if need fast processing waste water, after then needing to add more microorganism and preferably adding microorganism, allow microorganism mix fully with waste water through suitable stirring.
Similarly, the reaction times of waste water of the present invention and microbial mixture can change as required, and this depends on for example amount, desirable processing speed and the required treatment effect that reaches etc. of kind, waste water and the cyclodextrin of microorganism.Reaction times can from several hours to some months, for example from 5 hours to 30 days, preferred 10 hours to two weeks, as two days or three days.
After these microorganisms added waste water, microorganism broke away from dormant state and comes into play.This moment, microorganism began breeding, the uncombined carbon hydrogen compound in the food digestion effluent sewage.
According to the present invention, for quickening the breeding amount of microorganism, can in effluent sewage, add an amount of fertilizer (nitrogen, phosphorus, potassium) or nutritive substances such as sugar, starch sometimes.These nutritive substances not only can quicken the microbial reproduction amount, and the cyclodextrin mixed molecules in easy and original effluent sewage is bonding, make microorganism look for cyclodextrin easily, increase the marked effect of wanting the disaggregating treatment molecule and the timeliness of quickening objectionable impurities in the microbiological degradation waste water.The joining day of these nutritive substances can be before adding cyclodextrin or microorganism.Add in the process or afterwards.Add before preferably after adding cyclodextrin, adding microorganism.
Microorganism adapts to the ecotope in the effluent sewage gradually in reproductive process, and begins to decompose cyclodextrin and its accompanying chemical substance.Harmful chemical reaction in microorganism and the waste water is many-sided and complicated, it is not simple one step, for the hydrocarbon polymer that is entangled or cling by cyclodextrin, surrounded by Institute of Micro-biology around the overall molecule structure, microorganism out of the ordinary is disengaged specific ferment to this specific chemical and strives this specific chemical of food digestion mutually.The chemical substance of decomposing cyclodextrin and adhering in conjunction with strength when several or tens of kinds of ferment, original chemical substance is converted to the middle byproduct of other hydrocarbon polymer that is fit to microbiological degradation, the ferment that originally disengaged is passed to neozoic microorganism to the ability of handling harmful chemical, neozoic microorganism in conjunction with the specific ferment that originally disengaged in the chemical decomposition material process, again how the ability update of more effective chemical decomposition material in new ferment.A generation passes a generation like this, microorganism is adapted to how to decompose pending chemical substance.
As for byproduct in the middle of the hydrocarbon polymer in treating processes, then further decompose by other microorganisms, resolve into the hydrocarbon polymer of several segments, through multi-level digest and decompose, become fertilizer at last, protein, water and carbonic acid gas, various microorganism support each other but also mutual balance in the ecology of handling waste water.Use cyclodextrin in the effluent sewage and waste sludge of harmful chemical, provide one can allow the microorganism survival environment of panting basically, make microorganism in effluent sewage, have an opportunity progressively to develop and adapt to, decompose the objectionable impurities in the effluent sewage.When microorganism manifests when a certain particular chemicals had capacity of decomposition, microorganism will represent capacity of decomposition to similar particular chemicals.
The temperature of reaction of above-mentioned steps (b) can be the temperature of carrying out wastewater treatment usually, as carrying out at ambient temperature, and for example 0-45 ℃, preferred 5-40 ℃, more preferably 10-30 ℃.
Treatment process provided by the present invention, another key character are the heavy metal ion that can handle simultaneously in the waste water.Heavy metal ion itself and non-microorganism be the food of digest and decompose directly, but because cyclodextrin and metal ion bonding, or cyclodextrin and phenol metallic compound is bonding, and microorganism discharges specific ferment attempting digesting this bonding minute period of the day from 11 p.m. to 1 a.m.Ferment helps microorganism the oxygen particle combination that provides in heavy metal ion and the cyclodextrin.Specific ferment becomes the catalysis media, sees through the oxidized metal that katalysis is transformed into the heavy metal ion of higher potential energy low potential energy.Metal oxide through the microbiological oxidation generation, the general solid phase that becomes more, metal oxide just as the burning generation, chemical property is stable, because of proportion than the water height, be easier to be deposited at the bottom of the pond, available gravitational settling separates, filter or the centrifugation separation isolating oxidized metal, recyclable regeneration.In this unique biochemical reaction, actually contain two kinds of main treatment effects, first microorganism carries out decomposition reaction with harmful chemicals such as phenol; Two to be heavy metal ion reach the stable effect of oxidation by the oxygen particle and the enzyme microb of cyclodextrin for it.The processing mode of this oxidation heavy metal ion at normal temperatures and decomposition phenol chemical substance, applicable to the waste water in some circuit board process, the processing of waste lubrication oil solution and greasy dirt.
According to the present invention, the effluent sewage of handling contains the ferment of microorganism and generation thereof, in the effluent sewage that this was handled, adds the pending waste water that is mixed with cyclodextrin again, to quicken the decomposition timeliness of chemical substance in the pending waste water.
It can be diversified being suitable for waste water of the present invention or waste sludge, as the waste water in the circuit card manufacturing processed, the waste water that waste lubrication oil solution, organic synthesis chemical plant are discharged particularly contains those waste water of phenol chemistry matter or metal ion or phenol metallic compound.
