Description
Technical field
The present invention relates to measure the device of the BOD (biochemical oxygen required amount (or biochemical oxygen consumption figure)) of one of benchmark as the water quality of expression plant drainage or rivers and creeks water etc.; Promptly; The stoste of sample sample liquid only is set, just can automatically measures D1 value, as the D5 value of the mensuration project after five days and the BOD apparatus for automatically measuring of BOD value as first day mensuration project.
Background technology
As the benchmark of the water quality of measuring plant drainage or rivers and creeks water etc., the water quality benchmark of BOD is arranged, this assay method is stipulated in the standard of JIS-KO102:2008.
Assay method as the BOD value; The sample liquid (stoste) that this JIS-KO102:2008 standard code (1) will be extracted from plant drainage or rivers and creeks water etc. is diluted to normal concentration, (2), and to measure the soluble oxygen content that sample liquid after diluted places after the stipulated time be five day time is preserved in D1 value, (3) after the D1 value is determined after as first value, and the soluble oxygen content of measuring identical sample liquid is that the operation of the residual quantity of D1 value and D5 value as the BOD value calculated in D5 value, (4) as second value.
The big situation of BOD value of sample liquid representes that the difference of D1 value and D5 value is big, compares with first day, and the 5th day soluble oxygen content significantly reduces.That is, expression BOD value is big more, the state that water quality is poor more.
At this, because D1 value is to measure on same day after extracting sample liquid, the D5 value is the mensuration of behind five days of the same day after the mensuration D1 value, being done, so the mensuration day of D1 value and D5 value is following.
Can know that from the corresponding relation of mensuration day of mensuration day of this D1 value and D5 value the D1 value only can be accomplished carrying out operation from the working day on Monday to Friday, but the D5 value also must be carried out operation on Saturday, Sun. (or festivals or holidays).Therefore, hope is with the mensuration robotization of D5 value.If the mensuration of D5 value can not robotization, for the mensuration of D5 value, operating personnel just must turn out for work on off-day, are created in cost aspect or managerial shortcoming.
In addition, for D1 value and the D5 value of measuring sample liquid, handwork is numerous and diverse, and the possibility of bringing out the mensuration mistake is big.Much less, be housed in the sample liquid in many mensuration containers the BOD value mensuration relatively the difficulty.
Under this situation, the various technology (for example, with reference to patent documentation 1,2,3) of the BOD value of sample liquid have been proposed to measure with automated manner.

[patent documentation]
[patent documentation 1] (Japan) spy opens flat 6--230013 communique
[patent documentation 2] (Japan) real opening put down 6-one 16864 communiques
[patent documentation 3] (Japan) spy opens the 2004-101495 communique
But the apparatus for automatically measuring of patent documentation 1 has to be taken care of the sample bottle after the mensuration end of D1 value at the reception room of special use, after five days the sample bottle of being taken care of is taken out, and measures the structure of D5 value with the identical mensuration mechanism that measured the D1 value.That is, measure mechanism to one, conveyer will separate time interval of five days and send identical sample bottle to, measures the soluble oxygen content that mechanism measures the sample bottle of first day and the 5th day for one.
Therefore, the apparatus for automatically measuring of patent documentation 1 has the problem that the sample bottle number that can measure receives the capacity limit of conveyer.In addition, because operation is to the new sample bottle of conveyer input by hand, because operating personnel's error, can produce problems such as the D5 value of the sample bottle that is not the 5th day is determined.Particularly because the D1 value is to measure with identical mensuration mechanism with the D5 value, so, determined or be not which of D1 value and D5 value at determined this respect of correct date, also there is the problem of the mistake that handwork or directional error cause.In addition; Because the apparatus for automatically measuring of patent documentation 1 is through manually carrying out the dilution of stoste; With the sample bottle after its dilution by hand operation drop in the apparatus for automatically measuring, therefore have the problem that operation is numerous and diverse, be easy to generate the error of the operation that handwork causes.
Like this, there is the limited and essential handwork partly of the number of sample bottle in the technology of patent documentation 1, thus the problem of the mensuration that the error of generation handwork or device causes error.
But; With patent documentation 1 likewise; Because be identical determination part mensuration D1 value and D5 value, thus there be error and operating personnel's pallet setting or the operation error that pallet moves owing to the travel mechanism of pallet, and measure the problem of D5 value on the date that should not be requirement originally.In addition, in the technology of patent documentation 2, the sampling receptacle that the D1 pH-value determination pH finishes need be taken care of at the site of storage of special use.Therefore, be created in the problem that also needs special-purpose site of storage beyond the device.Because hope site of storage keeping and from site of storage take out sampling receptacle all by hand operation carry out, so also might produce the operation error.If produce the operation error in keeping or in taking out, will occur in the problem that wrong dates is measured the D5 value.
The technology of the automatic analysing apparatus of patent documentation 3 expression does, the accumulator and the accumulator of measuring D5 value of D1 value measured in preparation, drop into these accumulators after, the embolism of container is opened new specified D1 value or D5 value, make the container after the mensuration end return accumulator.At this moment, through accumulator being divided many days inputs, also can measure on Saturday or Sun..
But, identical with patent documentation 1 with patent documentation 2, the shared identical mechanism of mensuration mechanism of mensuration D1 value and D5 value.Therefore, when producing error in the input operation of accumulator, can be created in the problem that wrong dates is measured the D5 value.In addition, because the mensuration of the sampling receptacle that is arranged on accumulator is carried out, the accumulator of the container of the mensuration end of keeping D1 value need be taken care of at the site of storage of special use.Therefore, generation needs the problem of site of storage.
In addition, because hope the keeping of site of storage and extract sampling receptacle out all to be to carry out, so the possibility that produces the operation error is also arranged through handwork from site of storage.If produce the operation error in keeping and the extraction, will be created in wrong dates and measure D5 value problem.
In addition; The technology of patent documentation 3 is in the automatic dilution device different with automatic analysing apparatus, to measure the operation that stoste is diluted, and can produce because the error in the dilution operation, maybe the problem in the automatic analysing apparatus is got and be arranged on to the sample liquid after will diluting wrong.
Like this, the apparatus for automatically measuring of prior art has following problem, that is: (1) owing to be to measure D1 value and D5 value with identical mensuration mechanism, results from handwork error or directional error and in the problem of wrong dates mensuration D5 value; (2) problem of the site of storage of the special use of the sampling receptacle of the mensuration end of needs keeping D1 value; The operation of (3) stoste being diluted is the problem of other operation; (4) the operation error problem that cause, that carry out wrong sample determination of the sample liquid after will diluting through handwork when determinator is provided with; (5) in mensuration, owing to need various handworks, make the inadequate problem of robotization.
Because of these problems, also can produce the D5 value of Saturday, Sun., festivals or holidays mensuration and the operation of diluting, can not full automatic problem from taking-up operation of site of storage etc.
Summary of the invention
The present invention is in view of above-mentioned problem; A kind of stoste that only is provided with is provided, makes mensuration, the D1 pH-value determination pH of dilution, D1 value finish the whole robotizations of discharge of back container are finished in the back to mensuration, the D5 pH-value determination pH of D5 value to the keeping of container, on the correct date BOD apparatus for automatically measuring.
In order to solve above-mentioned problem; BOD apparatus for automatically measuring of the present invention possesses: the sample liquid that will measure after first value is taken care of; Measure second determinator of its second value until first determinator of the collecting storage facility of measuring second value, mensuration sample liquid first value, from collecting storage facility taking-up sample liquid; Collecting storage facility has a plurality of date framves of the keeping every day sample liquid after measuring first value; First determinator has multiplying power dilution unit that sample liquid is diluted by regulation, make standby unit in the diluted sample liquid above standby at the appointed time of dilution unit, be determined at the standby of standby unit sample liquid first value first determination unit, the sample liquid injection container that will measure at first determination unit and container is fed to the feeding unit of date frame; Second determinator has from the retrieval unit of the frame taking-up container corresponding with the date of measuring second value, from the container that is taken out by retrieval unit, extracts sample liquid, measures second determination unit of second value.
The invention effect
BOD apparatus for automatically measuring of the present invention only is provided with stoste, just can make the mensuration of dilution, first value, the mensuration of first value finish back keeping to container, on the correct date mensuration of second value, the mensuration of second value finished the whole robotizations of discharge of back container.
In addition, first determinator is different mechanisms with second determinator, thereby can prevent the mensuration day of first value and the mistaken problem of mensuration day of second value.In addition because can separated measuring first value be worth with second, so can measure simultaneously as the mensuration of the D1 value of first value with as the D5 value of second value.
Especially with each the mensuration day after having carried out first pH-value determination pH container of first pH-value determination pH end keeping sample liquid being distinguished the collecting storage facility that carries out taking care of is benchmark, and first determinator and second determinator move independently.As a result, the differentiation that only depends on collecting storage facility mensuration day of second value corresponding with the mensuration day of first value is so it is mistaken that second determinator can not will be measured day.The differentiation of collecting storage facility only depends on the mensuration day of first value, and the mensuration day of first value does not also rely on the handwork beyond the operation that stoste is set, so, there is not the possibility of the mensuration day of getting first value wrong.
These results can prevent the error measurement that the handwork error causes.
In addition, with regard to being determined under the situation of carrying out Saturday, Sun. and festivals or holidays of second value at last, also do not need handwork, second value can be measured automatically.
Certainly, need be at the container after site of storage keeping first pH-value determination pH end of special use.

(embodiment 1)
(whole summary)
At first, use Fig. 1 and Fig. 2 that the summary of the BOD apparatus for automatically measuring of embodiment 1 is described.
The BOD apparatus for automatically measuring of embodiment 1 only is provided with the sampling receptacle of sample liquids such as accommodating plant drainage or rivers and creeks water, automatically performs to measure needed all processing of BOD value, measures consequent BOD value.The BOD value is the numerical value of expression plant drainage or rivers and creeks water water quality, so getting involved the people in the operation halfway is operation, measures precision and might reduce.To this, the BOD apparatus for automatically measuring in the embodiment 1 automatically performs all process steps after the setting stoste, so nobody is the leeway that operation gets involved, can be with high-precision measuring BOD value.
Fig. 1 is the calcspar of the BOD apparatus for automatically measuring in the embodiment 1 of the present invention.Fig. 1 representes that diagrammatically the integral body of BOD apparatus for automatically measuring constitutes, the key element relation each other that expression BOD apparatus for automatically measuring possesses.Fig. 2 is the process flow diagram of the mensuration operation of the BOD apparatus for automatically measuring in the embodiment 1 of the present invention.Fig. 2 representes the operation that the BOD apparatus for automatically measuring is carried out.
As big key element, BOD apparatus for automatically measuring 1 possesses: collecting storage facility 2, and it takes in mensuration is storage container 54 as the container of the D1 value of first value; D1 analyzer 3, it is first determinator of the D1 value of mensuration sample liquid; And, analyzer 4, it is second determinator of D5 value for second value of measuring the inner sample liquid of the storage container that takes out from collecting storage facility 2 54.
Need to prove; In embodiment 1,, defined the D5 value as the example of second value though defined the D1 value as the example of first value; But, can change neatly by first value and the defined value of second value according to the bioassay standard or the step change of relevant BOD value.
Collecting storage facility 2 is distinguished the storage container 54 of accommodating the determined sample liquid of D1 value in D1 value determined every day.Therefore, collecting storage facility 2 possesses date frame 20a～20e.D1 analyzer 3 is measured the D1 value of the sample liquid of former liquid container 50 inside, and is corresponding with the date of measuring.Accommodate the storage container 54 of the sample liquid of D1 pH-value determination pH end to date frame 20a～20e supply.D5 analyzer 4 takes out the storage container 54 of the corresponding date frame of date before five days that measure day with D5 from the date frame that collecting storage facility 2 is possessed, measure the D5 value of the inner sample liquid of the storage container that taken out.D5 analyzer 4 will be fed to expression and measure the discharge frame 21 that finishes at the storage container 54 of the sky after the D5 pH-value determination pH finishes.
The D1 value is the value of sample liquid at first day soluble oxygen content, and the D5 value is the value of the soluble oxygen content of sample liquid after five days, all is the BOD value parameters needed of measuring sample liquid.The value of calculating according to D1 value and D5 value is then represented the BOD value of sample liquid water quality.
The collecting storage facility 2 that BOD apparatus for automatically measuring 1 will be taken in the storage container 54 of the determined sample liquid of D1 value is made as benchmark, and D1 analyzer 3 can move with D5 analyzer 4 separately independently of each other.Like this; It is middle that collecting storage facility 2 is installed in; And D1 analyzer 3 moves with D5 analyzer 4 independently; Thereby, collecting storage facility 2 only positively, take in storage container 54 with distinguishing, mensuration and the D5 analyzer 4 that just can carry out 3 pairs of D1 values of D1 analyzer error freely with the mensuration of the mensuration day that is associated the mensuration day of this D1 value to the D5 value.
Like this; BOD apparatus for automatically measuring 1 in the embodiment 1 is a benchmark with collecting storage facility 2; D1 analyzer 3 and D5 analyzer 4 are arranged on its both sides; At an end of collecting storage facility 2 former liquid container of accommodating stoste 50 that is provided with D1 analyzer 3 and the storage container 54 of accommodating the sample liquid of having measured D1 are managed,, the storage container 54 of accommodating the sample liquid that D5 analyzer 4 measures is managed at the other end of collecting storage facility 2; Not only can prevent the maximization of locking apparatus or equipment thus, and can carry out the mensuration of free from error BOD value.
BOD apparatus for automatically measuring 1 is for realizing aforesaid function, and D1 analyzer 3 and D3 analyzer 4 possess the unit of regulation separately.
Collecting storage facility 2 possesses the date corresponding date frame 20a～20e determined with the D1 value; As a kind of mode, corresponding Thursday, the date frame 20e of corresponding Wednesday, the date frame 20d of corresponding Tu., the date frame 20c of corresponding Monday, the date frame 20b of date frame 20a corresponding Friday.And then collecting storage facility 2 possesses also that the BOD value calculate to finish and the discharge frame 21 that receives unwanted storage container 54.
In addition, D5 analyzer 4 possesses from the deliverying unit 43 that date frame 20a～20e takes out second determination unit that the retrieval unit 40 of storage container 54, the soluble oxygen content of measuring the sample liquid in the storage container 54 are D5 value, storage container 54 that the D5 pH-value determination pH is finished is discharged to discharge frame 21.
In addition, D1 analyzer 3 and collecting storage facility 2 can be connected with storage container 54 with removing.In addition, collecting storage facility 2 and D5 analyzer 4 can be connected with storage container 54 with removing.Feeding unit 37 is that benchmark automatically performs processing with retrieval unit 40 with collecting storage facility 2.
These unit possess each unit separately and carry out the mechanism needed machinery of processing, electricity, carry out desired operation.
(treatment step of BOD apparatus for automatically measuring)
Then, use Fig. 1, Fig. 2 that the treatment step of BOD apparatus for automatically measuring 1 is described.Fig. 2 is whole as flowcharting D1 analyzer 3, collecting storage facility 2 and the 4 whole processing of being carried out of D5 analyzer.
At first,, contain former liquid container 50, be set at former liquid container being provided with on the platform of operation 30 is set as sample liquids (stoste) such as the plant drainage of determination object or rivers and creeks water at step ST1.This former liquid container 50 is to be provided with for operation through the people, but is understood that also and can be provided with automatically through crane or conveyer.
Secondly, at step ST2, dilution unit 31 is carried out the sample liquid injection cut-back tank 51 that will be contained in former liquid container 50 and the dilution operation of diluting.The dilution operation execution through the use JISKO102:2008 (below be called " JIS standard ".) in the dilution water of defined, in cut-back tank 51, sample liquid is diluted.Dilution unit 31 based in the JIS standard fixed method sample liquid is diluted to the dilution ratio of regulation.
Then, at step ST3, standby unit 32 makes the standby container 52 that has injected sample liquid from cut-back tank 51 carry out standby through more than the stipulated times.This operation is the standby operation.In the standby operation, standby unit 32 make standby container 52 through the JIS standards carry out standby more than fixed stipulated time.Because when this stand-by time was insufficient, the D1 value was measured under inadequate diluted state, the result can calculate the BOD value with incorrect value.
Then, at step ST4, the sample liquid of D1 determination unit 33 after with standbies in the standby container 40 injects D1 and measures container 53, measures D1 value, and D1 measures container 53 and will narrate with figure at the back.This operation is the D1 mensuration operation as the first mensuration operation.D1 determination unit 33 based on the JIS standard fixed method, use known unit etc. to measure the D1 value.The D1 value of being measured is stored in the storage part of regulation as determination data, or is printed on the recording chart of regulation as determination data.
In addition, parallel with step ST1～ST4, at step ST5, by storage container feeding unit 34 supply storage containers 54.Expression has treatment step ST5 between step ST4 and step ST6 among Fig. 2, but also can be at step ST4 with pre-treatment step ST5.Generally speaking, as long as before step ST6, the sample liquid that the processing of step ST5 finishes, the D1 pH-value determination pH finishes is reloaded to be taken in employed storage container 54 to collecting storage facility 2 and gets final product.Need to prove that storage container 54 also can be supplied through manpower.Perhaps with supply storage containers 54 such as belt conveyor or cranes.
Then, at step ST6, refitting unit 35 will be contained in the sample liquid that D1 measures the determined D1 value of container 53, reload the storage container of being supplied from storage container feeding unit 34 54.This operation is the refitting operation.Storage container 54 is arranged in warehouse etc., and thereafter, the warehouse 80 that is provided with a plurality of storage containers 54 is delivered to storage container 54 the date frame 20a～20e of collecting storage facility 2.
Then, at step ST7, plug sealing unit 36 will be filled in sealing to the peristome of the storage container 54 of accommodating the sample liquid that the D1 pH-value determination pH finishes.This operation is the plug sealing process.Plug sealing unit 36 possesses not shown robot arm, and the peristome of itself and storage container 54 is as one man set stopper 54a, stopper 54a is pressed into peristome fills in sealing.Because of the effect of sealing plug, the storage container 54 of accommodating the sample liquid that the D1 pH-value determination pH finishes can not receive the influence of outside atmosphere gas, and when measuring the soluble oxygen content after a few days, the result of mensuration only depends on storage container 54 inside (being sample liquid itself).The storage container 54 of having filled in sealing in collecting storage facility 2 during keeping, only consume by the contained microorganism of sample liquid etc., taken care of down at the state that soluble oxygen content is changed.
Then, at step ST8, the storage container 54 that feeding unit 37 will be filled in good seal is fed to collecting storage facility 2.This operation is the supply operation.Collecting storage facility 2 possesses the date frame 20a～20e corresponding with the date of determined D1 value.Feeding unit 37 is supplied storage container 54 to date frame 20a～20e corresponding with the date of determined D1 value.
Then, at step ST9,2 pairs of storage containers of being supplied by feeding unit 37 54 of collecting storage facility are taken care of at the appointed time.This operation is the keeping operation.

(supply operation)
Then, supply operation etc. is described.
At first, refitting unit 35 sample liquid that will accommodate the mensuration container 52 of the sample liquid that the D1 pH-value determination pH finishes reloads storage container 54.This operation is as shown in Figure 5.Storage container 54 is collecting storage facility 2 used containers when taking in, and is provided with and carries through storage container supply operation 34.Refitting unit 35 reloads this storage container of bringing 54 with the sample liquid that the D1 pH-value determination pH finishes from measuring container 53.
The storage container 54 that refitting finishes is coupled with stopper at plug sealing unit 36.Through the plug sealing, the sample liquid in the storage container 54 is taken care of in collecting storage facility 2, thereby can not receive externalities.
The supply operation uses feeding unit 37 to collecting storage facility 2 supply storage containers 54.
At this, collecting storage facility 2 possesses the date corresponding date frame 20a～20e determined with the D1 value.The mensuration day of the corresponding D1 value of date frame 20a is the situation on Monday; The mensuration day of the corresponding D1 value of date frame 20b is the situation on Tu.; The mensuration day of the corresponding D1 value of date frame 20c is midweek situation; The mensuration day of the corresponding D1 value of date frame 20d is the situation on Thursday, and the mensuration day of the corresponding D1 value of date frame 20e is the situation on Friday.Need to prove that in the present situation, usually, Saturday and Sun. are off-day, collecting storage facility 2 shown in Figure 1 does not possess the date frame on corresponding Saturday and Sun..Certainly, collecting storage facility 2 also can also possess the date frame on corresponding Saturday and Sun..In addition, collecting storage facility 2 also possesses the discharge frame 21 of (calculating that the is the BOD value finishes) storage container 54 of discharging the end of D5 pH-value determination pH.
As shown in Figure 7, D1 analyzer 3 moves (perhaps, feeding unit 37 moves) to the direction with the throughput direction quadrature of collecting storage facility 2, to the determined corresponding date frame supply storage container 54 of date of D1 value.Fig. 7 is the synoptic diagram of the relation of date frame and D1 analyzer and the D5 analyzer of expression in the embodiment 1 of the present invention.
Feeding unit 37 is to measuring the storage container 54 that day corresponding date frame supply is collected in warehouse 80 with D1.At this moment, D1 analyzer 3 or feeding unit 37 move relative to the throughput direction of collecting storage facility 2, and thus, feeding unit 37 date frame supply corresponding with the mensuration day of D1 value in date frame 20a～20e is collected in the storage container 54 in the warehouse 80.For example, be under the situation on Monday in the D1 pH-value determination pH day of having measured the D1 value, feeding unit 37 is as shown in Figure 7 to date frame 20a supply storage container 54.
In addition, feeding unit 37 also can directly be fed to date frame 20a～20e with storage container 54, and is as shown in Figure 7, also can with the state supply in the collector warehouse 80.
In addition, the mensuration day of D1 value is under the midweek situation, and feeding unit 37 is to date frame 20c supply storage container 54.
Like this, feeding unit 37 moves to vertical direction or horizontal direction relative to collecting storage facility 2 on one side, measures the storage container 54 of accommodating the sample liquid of D1 pH-value determination pH end day to the date frame supply corresponding with the mensuration day of D1 value Yi Bian distinguish each.
0130 collecting storage facility 2 can be distinguished the mensuration day of each D1 value sampling receptacle 30 is taken care of.
(keeping operation)
Then, the keeping operation is described.
0132 collecting storage facility 2 is last at the date frame 20a～20e corresponding to mensuration day of D1 value with storage container 54, in fixing environment stipulated time certainly down.Its stipulated time can be cultivated the sample liquid that is diluted.In addition, the five day time of defined describes in the JIS standard though the stipulated time is set at, and also can suitably change.
(taking-up operation)
Then, describe taking out operation.
The date frame 20a～20e of collecting storage facility 2 has the conveyer function separately, and the storage container 54 of D1 analyzer 3 supplies constantly moves to the end of D5 analyzer 4 sides from the end of D1 analyzer 3 sides.Through moving, the storage container 54 of accommodating the sample liquid of D1 pH-value determination pH end moves closer to D5 analyzer 4, makes D5 analyzer 4 take out storage containers 54 easily.
Take out in the operation, retrieval unit 40 takes out storage container from the date frame.At this, be decided to be the date behind five days of mensuration day of D1 value the mensuration day of D5 value.For example, the mensuration day of D1 value is under the situation on Monday, and the sample liquid that is housed in this storage container 54 need be measured analyzer D5 value on Friday.
Therefore, retrieval unit 40 in date frame 20a～20e, the date frame corresponding with the date before five days mensuration days of D5 value take out storage container 54.The mensuration day of D5 value is under the situation on Friday, retrieval unit 40 from five days before corresponding date frame 20a on Monday take out storage container 54.
Expression has this appearance among Fig. 7.With D1 analyzer 3 likewise, D5 analyzer 4 (retrieval unit 40) can move to the direction relative to the throughput direction quadrature of collecting storage facility 2.Through moving of orthogonal directions, retrieval unit 40 moves to the position of the date frame that needs, and takes out storage container 54 from the date frame.At this moment, retrieval unit 40 from five days mensuration days of D5 value before frame of pairing date on date take out storage container 54, so, needn't worry to get wrong the mensuration day of D1 value and with it the D5 value of correspondence mensuration day and calculate the BOD value.
(D5 measures operation)
Then, D5 being measured operation describes.
Measure operation at D5, D5 determination unit 41 is measured the soluble oxygen content of the sample liquid in the storage container 5 that is taken out by retrieval unit 40, i.e. D5 value.
Fig. 8 is the synoptic diagram that the D5 in the expression embodiment 1 of the present invention measures operation.Fig. 8 representes to be moved in D5 measures container by the storage container 54 that retrieval unit 40 takes out, and utilizes D5 determination unit 41 to measure the state of the D5 value of sample liquid.
The D5 that is sent to D5 determination unit 41 by the sample liquids in the storage container 54 of retrieval unit 40 taking-ups successively measures container 55.Fig. 8 representes to be sent to successively from storage container like this state of the D5 mensuration container 55 of D5 determination unit 41.
In addition, D5 analyzer 4 possesses the Kai Sai mechanism of the stopper 54a that opens storage container 54.Utilize this Kai Sai mechanism, D5 analyzer 4 is opened the stopper 54a of storage container 54, just can take out the sample liquid that is housed in wherein.
At this, the soluble oxygen content analyzer of the assay method identical type of the known technology that 41 uses of D5 determination unit and D1 determination unit are used is measured the D5 value.In addition, when the D5 pH-value determination pH finished, D5 determination unit 41 was discarded sample liquid in drain tank 411.As a result, it is empty that D5 measures container 55 changes.
In addition, D5 determination unit 41 is measured the sample liquid of the storage container 54 of the frame taking-up of corresponding date on date before five days mensuration days of the D5 value of taking out with retrieval unit 40.Retrieval unit 40 relative collecting storage facility 2 vertical moving, the date frame from needs takes out storage container automatically simultaneously.Therefore, D5 analyzer 4 is on Saturday or such off-day on Sun., also only takes out the storage container 54 that has prepared at collecting storage facility 2 from the date frame of correspondence, so, the mensuration of D5 value is failed.That is, on the working day from MONDAY to FRIDAY, operating personnel only set the former liquid container 50 of accommodating stoste at D1 analyzer 3, thereafter, measure operation until D5 and all can carry out automatically.As a result, can measure the D1 value and the D5 value of sample liquid based on the combination on correct date.
That is, D1 measures operation need measure the D1 value of sample liquid arbitrary day of MONDAY to FRIDAY, and BOD apparatus for automatically measuring 1 needs and must measure the D1 value on these all dates.About this point, after BOD apparatus for automatically measuring 1 is provided with the sample liquid as stoste, carry out the mensuration of D1 value automatically.And then, supply storage container 54 automatically from any of mensuration day on the corresponding date of trend and D1 value frame 20a～20e.
On the other hand, D5 analyzer 4 since be automatically from five days mensuration days of D5 value before corresponding date frame take out storage container 54, so the mensuration day that just is the D5 value is that Saturday or Sun. are also no problem, D5 mensuration operation also can be measured the D5 value.
According to above situation; Collecting storage facility 2 with date frame 20a～20e of mensuration day of possessing each D1 value that can distinguishing assay D1 value is a benchmark; D1 analyzer 3 moves with D5 analyzer 4 independently of each other; Thus, no matter off-day such as Saturday or Sun., BOD apparatus for automatically measuring 1 can be measured the BOD value.
Therefore, can correctly measure the BOD value of sample liquid.In addition, collecting storage facility 2 is carried out taking in of storage containers and from the correct transfer to the mensuration of D5 value of the mensuration of D1 value, so BOD apparatus for automatically measuring 1 can have both the high efficiency of operating efficiency and operating area.
When D5 determination unit 41 is measured the D5 value, the D5 value is stored in storage part as determination data.
In addition, D5 determination unit 41 calculates according to D5 value and D1 value, calculates the BOD value.The water quality of this BOD value representation sample liquid.With the D5 value likewise, D5 determination unit 41 is stored in storage part with the BOD value or is printed on the recording chart.That is, D5 determination unit 41 also possesses the BOD computing unit 42 that calculates the BOD value.
(discharge operation)
In addition, Fig. 8 representes that also empty storage container 54 is to discharging the state that frame 21 is discharged.
It is identical with date frame 20a～20e to discharge frame 21, also possesses transport sector, the storage container 54 of the sky that is received along the prescribed direction conveying warehouse 80 of this empty storage container 54 (or collect).Carry through this, operating personnel can be transferred to matting etc. with the storage container 54 of the sky that should discharge.
(Kai Sai mechanism)
Kai Sai mechanism utilizes lever principle that stopper is opened.That is, Kai Sai mechanism has arm, makes the fulcrum pushing and the part that be connected of storage container 54 with plug 54a of this arm, and arm and this fulcrum are as one man launched, and thus, Kai Sai mechanism opens stopper.Certainly, Kai Sai mechanism also can possess the parts beyond the arm and utilize lever principle to open it, and utilizes the structure beyond the lever principle also can stopper be opened.
Utilize this Kai Sai mechanism, D5 analyzer 4 can be really and is easily opened the stopper 54a of storage container 54.
