In further detail with reference to the accompanying drawings, Fig. 1 illustrates one aspect of the present invention, is used for enzyme cleaning solution 10 is directed to remaining waste product 12, for example can find that this waste product adheres to the cosmetics tempering tank of closing or the surface of vessel, for example, wherein enzyme solutions 10 is convenient to clean waste product 12 from these vessel.From vessel surface cleaning waste product 12 time, the residual mixture of formed enzyme solutions 10 and waste product 12 is introduced into waste stream 14, this waste stream flows to the refuse food organism matter 16 with a lot of different organisms or bacterium that is contained in the container, this container is preliminary treatment septic tank system 18 for example, or balance chamber 20, or can directly be introduced into the sewerage 22 of guiding living beings chamber.Be separated into simpler form by the complicated molecule structure that will adhere to, the activity of enzyme is used for removing pollutant from vessel surface.This simple form is easy to continue to simplify other refuse that exists by the activity of living beings consumption and enzyme more.In order to reduce the possibility of infringement living beings 16, by with dilution 24 water for example, for example, introduce, guarantee that until reaching living beings 16 become or keep active in edible waste product 12 needed degree, and enzyme solutions 10 is handled.A lot of unicellular or multicellular organisms in the living beings or bacterium guarantee before waste stream is introduced in the surrounding environment 26 waste product in the waste stream 14 12 suitably to be handled.Therefore, when waste stream 14 finally is discharged into its respective environment 26, the possibility of the harmful side effect of environment 26 is lowered.
As shown in Figure 2, atoxic enzyme solutions 10 is made for the base solvent mixture usually aspect environment, it does not have antibacterial action and has surfactant-penetrating fluid-releasing agent (A) and for example can identify the enzyme component solution that SilzymeTM buys with product from the Renew Systems company of Michigan, Bay City, is called (B) below.Liquid mixture (A) can comprise the N-methyl pyrrolidone as surfactant-solvent (2.3-2.4%), and as penetrating fluid, and counterbalance is generally water to the ethyoxyl octyl phenol as binding agent-thickener (2.2-2.3%) and ester alcohol (1.5-1.6%).By preventing that living beings 16 from being suppressed by oil, grease and fatty refuse, surfactant-penetrating fluid system (A) to small part is used to stop the infringement for living beings 16.Enzyme solutions (B) can contain one or more enzymes for example lipase, Alpha amylase, protease (1.8-1.9%) etc., or its mixture in the enzymatic protective reagent stabiliser solution with propane diols (1.8-1.9%) etc.(A) and mixture (B) have volume/ratio like this substantially, promptly at least 90 parts (A) to 10 parts (B) or alternately 10 parts (A) is to 1 part (B), the percentage of being illustrated is determined by volume.Mixed about two hours of formed mixture, and after this, carry out turbidity and pH and measure.Alternately, estimation can be with RenewSystems Acqueous Reactivator
TM, Xzyme
TMAnd Decontaminator
TMThe enzyme cleaning agent of buying can be used as cleaning solution.The term enzyme is used to comprise known complex proteins here, and it is produced by the living cells of HMW and is made of multiple amino acid, and these amino acid are combined in the structure of Q-character orientation, and newer and genetic engineering enzyme component.The type of a large amount of basic enzyme can comprise hydrolase, isomerase, ligase, lyase, oxidoreducing enzyme and transferase.More specifically, can produce enzyme by the fermentation of a kind of bacillus licheniformis.The enzyme that is used for part (B) can be in the scope of 0.5-3% according to percent by volume.
When measuring the pH of mixture (AB), determine the sodium borohydride (NaBO4) how many depletions for example mix in water, use (C) expression below, need be added to mixture (AB) so that mixture reaches the pH neutral range that can work, in the scope that is restricted on the pH meter at 6-8.Depletion (C) by will the amount of determining adds mixture (AB) to, measures the pH (see figure 3) once more.If pH is arranged in the pH neutral range of appointment, then formed mixture (AB) and (C) is called (ABC) below, can use fully.Yet if mixture (ABC) not in the pH neutral range, adds more depletion (C) to improve the pH level, perhaps for example citric acid or hydrochloric acid solution of acid solution for example, can add mixture (ABC) to reduce pH.Usually, mixture (ABC) can be used immediately, perhaps reaches 90 days or more time common the storage in the peripheral temperature of 52-78 degree.
In use, before using or following closely, (ABC) is directed to living beings 16 with liquid mixture, importantly, set in advance mixture (ABC) and make it have the ratio of predetermined mixture (ABC) and dilution 24.Ideally, the ratio of the water that mixture (ABC) comprises is the water of 1 part of mixture (ABC) and 2000 parts, if the supply of this water can obtain in sewerage.As in Fig. 3 with curve schematically, under this ratio, the respirometer experimental result has shown and is used to make living beings 16 to be adapted to the time lag of the new waste stream of introducing 14 that this moment, living beings 16 began to digest waste product 12, were negligible.Experimental result also shows, compares with the result of independent utilization test control water generates, and the refuse oxidation results is same favourable at least, and slightly more favourable usually.Importantly, have the mixture (AB) of waste product 12 or (ABC) can be directed to living beings 16 with lower diluted state, comprise being low to moderate 1 part of mixture (ABC) and waste product 50 parts water.At this ratio, the respirometer experimental result shows the 12 hour time for originally, living beings 16 remain inactive substantially or non-adaptation, and then, unexpectedly, beginning is with the speed of final raising digestion waste product 12, finally causes the respirometer reading to reach and surpasses the reading (Fig. 3) that makes water separately.Correspondingly, with mixture (ABC) before waste product 12 is introduced living beings 16, mixture (ABC) need be diluted at least predetermined degree.Should be realized that, a lot of refuses water source that in industrial equipment, flows can be combined in public pipeline or the drainage in case before it arrives living beings 16 diluted mixture thing (ABC).The dilution 24 that also will be appreciated that at least a portion can be introduced in the waste stream 14 by the container that is cleaned.Ideally, remove from container or exhaust mixture (ABC) during or following closely, dilution 24 can be added to container and be released to waste stream pipeline 14.With as record by respirometer test result or another suitable measuring system, supply water according to the required amount of the diluted state of the waste stream that arrives living beings.Desirable waste stream will be included in for example water of 2000 to 100000 parts of dilutions in the scope of a mixture (ABC).Work as Silzyme
TMTo Synthetic Detergent Wastewater is 1/1000 o'clock, and biochemical oxygen demand (BOD) roughly is 58% of a COD (COD).Only for synthetic wastewater, BOD roughly represents 51% of COD.Silzyme with BOD of its higher percentage
TMHandle waste water and represent the refuse that to handle more of biosystem.
When reaching mixture (ABC) to the ideal ratio of dilution 24, carry have product remnants for example silicones, fat and grease or think synthetic plastic is for example arranged, the mixture (ABC) of the waste product 12 of latex and oil arrives living beings 16.As example and unrestricted, can find this waste product 12 at the vessel that be used for preparing cosmetics.When handling vessel, formed mixture (ABC) and dilution 24 and waste product 12 be via waste stream 14, for example by in the gutter that directly is discharged into the living beings sewerage for example of leading, and finally transferred to environment 26.In whole cleaning and digestion process, the temperature of solution A B or ABC remains on active temperature, wherein the more complex waste molecular dissociation that enzyme solutions catalysis or acceleration will be bigger becomes form simpler, that be easier to digest, and this makes the metabolic rate in the living beings 16 increase.Should be realized that sewerage can contain the living beings 16 of natural formation, these living beings have the edible bacterium of active refuse that forms from daily refuse, for example comprise, are contained in dregs material in the septic tank etc.It will also be appreciated that to be different from directly to be discharged in the sewerage that mixture (ABC) and waste product 12 can preferably be introduced in the pretreatment system 18, for example filter apparatus so that for example remove solid, basic simultaneously permission fluid flows through.Consider various known filtration apparatuses here, for example crossed film, sand filter, belt press, plate and frame type filter-press and for example centrifugal apparatus.
In other situation, mixture (ABC) and dilution 24 be together with waste product 12, and silicone oil for example for example, can be introduced into and wherein has in equilibrium natural generation or artificial creature's matter 16 (gathering) system 20.Artificial creature's matter 16 can be bought from a lot of companies, for example from BioChem
TMTechnology company (King of Prussia, PA or Biodyne of Sarasota, FLA) for example.Living beings 16 are conditioned then to be adapted to waste stream feature and the environmental condition in the concrete industrial equipment.Counterbalance cell 20 provides the mixture (ABC) that makes living beings 16 be adapted to exist and the time of waste product 12, therefore, be provided for making the metabolic rate of the bacterium in the living beings 16 to improve it to the picked-up of waste product 12 and the time of digestibility, the enzyme solutions in the mixture (ABC) keeps active in to utilize the complicated molecule in the enzyme disassociation refuse simultaneously.In order to obtain optimal result, temperature is held substantially the scope at 37 degrees centigrade to 45 degrees centigrade.Therefore, before it was introduced in the environment 26, living beings 16 can act on waste product 12.Ideally, dissolved oxygen sensor can use to describe the instantaneous reading of the oxygen content in the living beings effluent in conjunction with display board.Suitable DO meter (respirometer) can (VernonHills Illinois) buys, and as YSI 550A, has the DO meter of probe, to measure the dissolved oxygen in living beings 16 from A.Daigger and Company company.Correspondingly, be easy to determine when oxygen in the living beings 16 is measured as and has the rate that expression living beings 16 adapt to fully or have an effect.When living beings 16 adapt to and therefore begun to digest waste product 12, further waste product 12 is introduced making living beings 16 continue digestion waste product 12 in the living beings 16.Therefore, in case capture process begins, its keeps continuously, is fallen from 16 full consumptions of activated living beings in long-time except the waste product 12 that exists or other living beings can digest to remain in certainly.In order to make living beings be deacclimatized undesirablely, usually need be corresponding to the average cell retention time 2-3 in the living beings 16 times period.
Use the example of said process as follows:
Example
By introducing Silzyme
TM(ABC) pH controlled fluid jet purifies neutral silicon (siloxanes) emulsion of the pH with oil, fat and grease of mixing mutually from the wall of reaction and mixer.After about two hours clean cycle, residual stream is from the vessel surface discharging that now has been cleaned and blow down to the balance of closing releasedly or contain other tank septic tank for example of the biological plastid of bacterium alive.The ABC jet is introduced into the vessel that are cleaned or handle usually under diluted state, but can be not like this.If not like this, with at least according to the ABC of volume portion ratio water eluant container to 50 parts water.In any situation, utilize the water content of ABC liquid introducing and the water of in flushing, introducing to be measured to realize the ratio of 50-1 at least in living beings.The respirometer test will show that living beings kept non-activity in about 12 hours, after this, its adapts to and begins to handle (disassociation) fluid residual mixture and continue like this, until it continues to be supplied to other residual mixture from other cleaning vessel when the cleaning personnel are mobile from vessel to vessel.At this moment, corruption or other tank can be discharged into environment with residual stream.Living beings keep activity and adaptability, as long as be that the material supply is not interrupted in 24-36 hour for a long time.Add regulator solution by continuous monitoring and when needs keep the ph neutrallty condition at the ph of living beings content.
Other example
Under 1 part of ABC dilution to 20 parts of water, living beings inefficacies (being inactivated).Under 1 to 50,1 to 100 and 1 to 200 dilution, in 12 hour time, produced adaptability.At 1 to 2000 o'clock, a little higher than metabolic rate of utilizing water to realize separately of wastage (oxidation) metabolic rate that need not adaptation time basically and utilize respirometer to measure.Preferred dilution factor is 1 to 100.
Therefore should be appreciated that the foregoing description is an exemplary embodiment, and be intended to be used for signal and unrestricted.The scope of the invention is defined by the following claims.
