Description

  The present invention relates to a rinser drainage recovery device for recovering drainage from a rinser installed in an aseptic filling facility such as a soft drink, and more particularly, an apparatus particularly suitable for recycling a rinser drainage having a relatively low pollutant concentration. And so on.

  In aseptic filling equipment such as soft drinks, a container to be filled with a beverage is sterilized and washed with an apparatus called a rinser, and then a separately heat-sterilized beverage is filled in a sterile state by a filling machine. In this rinser, a container is sterilized with a sterilizing agent containing a peroxide such as hydrogen peroxide or peracetic acid, and then the container is rinsed with sterile water. The water used in the rinser is safe and high quality water equivalent to the raw water of soft drinks, that is, “drinkable water” defined by the Food Sanitation Law, and is suitable for washing after ultra-high temperature sterilization in aseptic water production equipment Sterile water cooled to temperature is used.

  Here, in general, in a rinser of a beverage aseptic filling facility, a beverage container is continuously sterilized and rinsed in conjunction with a beverage filling machine. For this reason, waste water containing peroxides such as hydrogen peroxide and peracetic acid is continuously discharged from the rinser. The kind and concentration of pollutants in the waste water from the rinser (rinser waste water) vary depending on the method of sterilization and rinsing with the rinser.

For example, Patent Document 1 discloses a conventional technique for treating the rinser drainage containing the peroxide. In the treatment apparatus described in Patent Document 1, peracetic acid-containing water is treated as follows to obtain reusable treated water.
1) Peracetic acid-containing wastewater is passed through an activated carbon tower to reduce peracetic acid to acetic acid.
2) The activated carbon effluent is passed through a cation exchange column to remove the cation of the counter ion of acetic acid.
3) The effluent from the cation exchange column is passed through the anion exchange column to remove acetic acid produced by reduction of peracetic acid and acetic acid derived from raw water.
As another technique described in Patent Literature, there has been proposed a treatment apparatus that removes acetic acid-containing water generated by the decomposition of peracetic acid with a reverse osmosis membrane (see, for example, Patent Literature 2).

JP 2001-129564 A (page 2-3, FIG. 1) JP 2001-170657 A (page 3-5, FIG. 1)

  According to the technique described in Patent Document 1 above, the counter ion of acetic acid derived from reduction of peracetic acid and acetic acid derived from raw water is removed by a cation exchange column and acetic acid by an anion exchange column, respectively. There are advantages that low-conductivity and high-quality treated water can be obtained, and the amount of drainage is small. However, in the technique described in Patent Document 1, equipment necessary for the regeneration of the cation exchange tower, the anion exchange tower, and the cation / anion exchange resin occupies about 50% of the equipment installation area, and the processing equipment becomes large. End up. In addition, it is necessary to neutralize the regenerated waste liquid and to manage the acid and alkali of the regenerant, which complicates operation management.

  On the other hand, the reverse osmosis membrane processing apparatus described in Patent Document 2 has a slightly smaller installation area than the ion exchange apparatus described in Patent Document 1. In addition, since no regenerant is used, there is an advantage that chemical management is unnecessary. However, the acetic acid-containing water produced by the decomposition of peracetic acid has a water temperature of around 40 ° C., contains acetic acid as a nutrient source for bacteria, and has a high dissolved oxygen concentration. It is inevitable that the permeable membrane is blocked. Therefore, it is necessary to regularly clean the reverse osmosis membrane treatment apparatus to ensure the flow rate of the permeated water, and the operation management becomes complicated.

  Thus, in the peroxide-containing rinser wastewater recycling apparatus having a desalination apparatus such as a conventional ion exchange processing apparatus or reverse osmosis membrane processing apparatus, the proportion of the demineralization apparatus is large, and Operation management was also complicated. However, from the viewpoint of effective use of water resources and reduction of the load on the water environment by reducing the amount of wastewater, the necessity of collecting rinser wastewater from aseptic filling equipment is increasing.

The present invention has been made in order to solve the technical problems as described above, and the object of the present invention is to provide a wastewater recovery device that has a smaller installation area and easier operation management than the conventional device. It is to provide.
Another object of the present invention is to provide a recycling apparatus for peroxide-containing rinser wastewater that is excellent in economy and the like, for treating and recovering the rinser wastewater containing peroxide into the rinser.

As a result of intensive studies by the present inventors, the following contents have been found and the present invention has been achieved.
1) For rinser wastewater with relatively low pollutant concentration, if the peroxide in the wastewater is decomposed by the activated carbon tower, potable water that can be recycled and used in this rinser is obtained.
2) Acetic acid is the main pollutant that accumulates in the water by circulating the treated water, and the acetic acid concentration can be controlled with a TOC (organic carbon) meter or electrical conductivity meter.
3) Bacterial growth in the activated carbon tower can be suppressed by sterilizing the activated carbon tower with hot water, and acetic acid adsorbed on the activated carbon is desorbed with hot water to restore the acetic acid adsorption ability of the activated carbon.

  That is, the present invention is a rinser drainage recovery device that is connected to a rinser of an aseptic filling facility, processes wastewater discharged from this rinser, and collects and reuses it in the rinser. Understand activated carbon tower to be decomposed, cartridge filter to remove activated carbon fine particles leaking from this activated carbon tower, information on the total treated water quantity or water quality of the rinser wastewater circulating through the activated carbon tower and cartridge filter, And a control unit for controlling the discharge of the circulated and used rinser drainage to the outside of the machine.

Here, if the information on the accumulated treated water amount grasped by this control unit is the accumulated treated water amount grasped by the accumulated flow meter or the passage time grasped by the passage timer, a simple mechanism It is preferable in that drainage control can be executed.
Moreover, if the information on the water quality grasped by this control unit is a value grasped by a TOC (Organic Carbon) meter or an electric conductivity meter, depending on the grasping state of the circulated water It is excellent in that good drainage control can be performed.

Furthermore, this control unit controls the opening and closing of the drain valve that discharges the rinser drainage to the outside of the machine, and after opening the drain valve and starting the discharge of the rinser drainage to the outside of the machine, It is characterized by grasping information and closing the drain valve based on the grasped information.
Further, by further including a heat exchanger that generates hot water used for cleaning the cartridge filter and / or the activated carbon tower, for example, it becomes possible to prevent the cartridge from being blocked by pulverized coal. Acetic acid adsorbed on the granular activated carbon can be released and discharged out of the apparatus.

  On the other hand, the rinser drainage recovery system to which the present invention is applied is a treatment of aseptic filling equipment rinser for sterilizing and washing containers, a rinser drain receiving tank for receiving rinser drainage discharged from the rinser, and wastewater discharged from the rinser. Rincer drainage recovery device for recovery and reuse by the Rincer, Rincer drainage pump for supplying Rincer drainage from the Rincer drainage tank to the Rincer drainage recovery device, treated water treated by the Rincer drainage recovery device and supply water supplied And a sterile water production apparatus for sterilizing water obtained from the relay tank. The rinser waste water recovery device is used in a circulating manner through an activated carbon tower for decomposing peroxide contained in waste water, a cartridge filter for removing activated carbon fine particles leaking from the activated carbon tower, and the activated carbon tower and the cartridge filter. And a control unit for controlling the discharge of the recycled rinser drainage to the outside of the machine.

From another point of view, the present invention is a rinser drainage recovery method for treating drainage discharged from a rinser of an aseptic filling facility and recovering and recycling it to the rinser, which is included in drainage from the rinser. Information on the total treated amount of wastewater that passes through the activated carbon tower and the cartridge filter by circulating the rinser waste water through the activated carbon tower that decomposes the peroxide and the cartridge filter that removes the activated carbon fine particles leaking from the activated carbon tower, or It is characterized by grasping information on water quality and discharging the recycled rinser wastewater to the outside based on the grasped information.
Here, based on this grasped information, the drain valve is opened to discharge the rinser drainage to the outside, and the drain valve is closed based on the information on the accumulated drainage amount or the information on the water quality after the drainage valve is opened. Thus, it is possible to realize more economical recycling of the rinser drainage.

  ADVANTAGE OF THE INVENTION According to this invention, compared with the conventional apparatus, the installation area is smaller, operation management is easy, and the waste_water | drain collection | recovery apparatus excellent in economical efficiency can be provided.

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings.
FIG. 1 is a diagram showing an overall configuration of a rinser drainage recovery system 100 to which the present embodiment is applied. A rinser drainage recovery system 100 shown in FIG. 1 includes, for example, an aseptic filling facility rinser 10 for sterilizing and washing containers such as bottles and caps filled with beverages, and a rinser drainage recovery device for recovering and reusing the rinser drainage. 20. The rinser drainage recovery system 100 includes a rinser drainage receiving tank 11 that receives the rinser drainage discharged from the aseptic filling facility rinser 10, and a rinser drainage pump 12 that supplies the rinser drainage of the rinser drainage receiving tank 11 to the rinser drainage recovery device 20. I have. Further, the rinser drainage recovery system 100 includes a relay tank 13 that combines the treated water processed by the rinser drainage recovery apparatus 20 and the supplied makeup water. Furthermore, the aseptic water production apparatus 14 which sterilizes the water obtained from the relay tank 13 is provided.

  In the rinser drainage recovery system 100 shown in FIG. 1, the rinser drainage discharged from the aseptic filling facility rinser 10 is received in the rinser drainage receiving tank 11 and sent to the rinser drainage recovery device 20 by the rinser drainage pump 12. The rinser drainage sent to the rinser drainage recovery device 20 is processed by the rinser drainage recovery device 20 and then sent to the relay tank 13. In the relay tank 13, supplementary water is added to supplement the amount of water discharged (drained) outside the apparatus in the water changing process (described later) and the activated carbon tower cleaning process (described later) executed in the rinser drainage recovery apparatus 20. . The combined water of the treated water from the rinser drainage recovery device 20 and the supplemental makeup water to be supplemented is subjected to an ultra-high temperature sterilization process in the aseptic water production device 14, and then cooled to a temperature suitable for cleaning, and the aseptic filling equipment rinser 10 and used for rinsing containers sterilized with peroxide-containing disinfectant.

Here, the flow rate of the rinser drainage discharged from one beverage filling line is, for example, 20 to 30 m ³ / h, and the temperature is, for example, 40 to 50 ° C. The type and concentration of contaminants in the rinser drainage differ depending on the method of sterilization and rinsing in the aseptic filling facility rinser 10. For example, in the water quality of a relatively low concentration rinser wastewater, the hydrogen peroxide concentration is about 5 to 50 mg / L, acetic acid is about 0.1 to 0.3 mg / L, peracetic acid is 0.1 mg / L or less, The conductivity is about 0.2 to 0.4 mS / m at 25 ° C. and pH is about 5.5 to 7.5.

  The makeup water added in the relay tank 13 is water suitable for drinking. Examples of the water suitable for beverages include water obtained by treating activated water with activated carbon to remove residual chlorine, water obtained by treating groundwater so as to be suitable for beverages, or treating these waters with an ion exchange treatment device or a reverse osmosis membrane treatment. Demineralized water treated with an apparatus or the like is used. In particular, as demineralized water having a TOC (organic carbon) lower than that of tap water, for example, ion-exchanged water having an electric conductivity of 1 mS / m at 25 ° C. or lower is suitable for circulating water.

  FIG. 2 is a configuration diagram detailing the rinser drainage recovery apparatus 20. The rinser drainage recovery apparatus 20 to which this embodiment is applied includes a recovery raw water tank 21 for storing the rinser drainage discharged from the rinser drainage receiving tank 11, and peroxides such as hydrogen peroxide and peracetic acid in the recovered raw water. An activated carbon tower 22 to be decomposed and a cartridge filter 23 for removing activated carbon fines in the treated water by the activated carbon tower 22 are provided. Further, a heat exchanger 24 for generating hot water to be supplied to the cartridge filter 23 and the activated carbon tower 22 in the hot water washing step (described later) is provided. The activated carbon tower 22 has a granular activated carbon packed bed inside. Hydrogen peroxide and peracetic acid, which are peroxides in the recovered raw water, come into contact with the granular activated carbon. Acetic acid is decomposed into acetic acid and oxygen, respectively. The cartridge filter 23 is not limited in type as long as it can filter the activated carbon fine powder leaking from the activated carbon tower 22 and can be applied with hot water sterilization by a hot water washing step (described later). However, it is preferable that the filtration accuracy of the cartridge is about 3 μm.

  The rinser drainage recovery apparatus 20 includes, as various pipes, a recovered raw water introduction pipe 31 into which recovered raw water is introduced, a recovered raw water pipe 32 that connects the recovered raw water tank 21 and the activated carbon tower 22, an activated carbon tower 22, a cartridge filter 23, and the like. Activated carbon tower treated water piping 33 and cartridge filter treated water piping 34 into which treated water from the cartridge filter 23 flows. Further, the rinser drainage recovery apparatus 20 includes a water quality meter 25 such as a water quality meter with alarm (AIA) provided in the recovered raw water introduction pipe 31, a recovered raw water pump 26 provided in the recovered raw water pipe 32, and the recovered raw water pipe 32. The integrated flow meter 27 is provided. As the water quality meter 25, for example, a TOC meter or an electric conductivity meter is installed. Furthermore, in the first drain valve 28 for discharging the system water of the rinser waste water recovery system 100 to the outside of the system, and hot water passing through the cartridge filter 23 and the activated carbon tower 22 in the hot water washing step (described later). And a second drain valve (activated carbon tower hot water sterilization drain valve) 29. Moreover, the control part 50 which controls the whole rinser waste_water | drain collection | recovery apparatus 20 is provided.

The wastewater discharged from the aseptic filling facility rinser 10 and passed through the rinser drainage receiving tank 11 is received and stored in the recovered raw water tank 21 through the recovered raw water introduction pipe 31 as recovered raw water. The stored recovered raw water is sent to the activated carbon tower 22 via the recovered raw water pipe 32 by the recovered raw water pump 26. The integrated flow meter 27 is used for integrated processing water volume management up to a water changing process in a water flow process, which will be described later, integrated processing water volume management up to the activated carbon tower cleaning process, and integrated drainage volume management in the water changing process.
In the control by the control unit 50, a water flow timer can be used instead of the integrated flow meter 27, and a water flow time grasped by the water flow timer can be used. In the case of controlling by the water flow time from this water flow timer, the use of a constant flow valve makes it possible to manage the accumulated water volume with high accuracy. This constant flow valve is installed in, for example, the activated carbon tower treated water piping 33 as a water flow piping capable of measuring the accumulated treated water amount in the water flowing step and the accumulated drainage amount in the water changing step.

  As described above, the treated water in the activated carbon tower via the activated carbon tower 22 is sent to the cartridge filter 23 by the pressure of the recovered raw water pump 26. The treated water of the cartridge filter 23 is sent to the relay tank 13 through the cartridge filter treated water pipe 34 and reused. The cartridge replacement frequency of the cartridge filter 23 is, for example, about once every three months. Note that other filters can be used instead of the cartridge filter 23 as long as the filter can collect the activated carbon fine powder.

Next, the operation | movement using each component of the rinser waste_water | drain collection | recovery system 100 shown in FIG. 1 and FIG. 2 is demonstrated.
The operation of the rinser drainage recovery apparatus 20 shown in FIG. 2 is broadly divided into three processes: a water flow process, a water replacement process, and a hot water washing process. Note that the switching of these processes and the driving operation in each process can be executed by an operation from an operation panel (not shown) in addition to the automatic control by the control unit 50 shown in FIG. Hereinafter, each step will be described.

FIG. 3 is a flowchart showing the flow of the water flow process and the water change process performed by the control unit 50.
First, in the water flow process, the recovered raw water pump 26 is operated under the control of the control unit 50, the recovered raw water stored in the recovered raw water tank 21 is passed through the activated carbon tower 22 and the cartridge filter 23 in this order, and the treated water is relayed. Processing to send to the tank 13 is performed (step 101). At this time, the activated carbon tower 22 decomposes peroxides such as hydrogen peroxide and peracetic acid in the recovered raw water, and the cartridge filter 23 removes activated carbon fine powder leaking from the activated carbon tower 22. Here, the processing is divided depending on whether the method to be executed is control based on the integrated processing water amount or water quality control (step 102). The quality of the treated water from the cartridge filter 23 is, for example, 0.1 mg / L or less for hydrogen peroxide and 0.1 mg / L or less for peracetic acid. In the process using the integrated process water volume, the integrated process water volume of the water flow process is acquired by the integrated flow meter 27 (step 103). Then, it is determined whether or not the set upper limit value has been reached (step 104). When it has not reached, it returns to step 101 and water flow is continued, and when it reaches the set upper limit value, it proceeds to the water changing process after step 110.

  The set value of the integrated treated water amount determined in step 104 can be determined as follows, for example. For example, suppose that the increase in TOC due to acetic acid is 0.2 mg / L when used as sterile water once in the aseptic filling equipment rinser 10 in the system of the rinser drainage recovery system 100. At this time, if the drinking water quality (tap water quality standard) is 5 mg / L, the water held in the system can be circulated and used 25 times by the aseptic filling equipment rinser 10 before reaching 5 mg / L. it can. Therefore, in such a case, the upper limit value of the integrated processing water amount setting is 25 times the in-system water amount. Since the quality of the recovered raw water fluctuates at the actual set value, it is preferable to set a value smaller than this set upper limit for safety. Here, the system water means the aseptic filling equipment rinser 10, the rinser drain receiving tank 11, the recovery raw water tank 21, the activated carbon tower 22, the cartridge filter 23, the relay tank 13, the relay tank 13, and the sterile water production in the rinser drain collection apparatus 20. In addition to the device 14, it means water held in communication piping including various pumps and valves. Thus, it becomes possible to implement | achieve favorable waste_water | drain recycling, without complicating the whole control by controlling based on the information regarding an integrated processing water amount.

  On the other hand, when the water quality control is executed in step 102, the indicated value of the water quality meter 25 such as a TOC meter or an electric conductivity meter installed in the recovered raw water introduction pipe 31 is acquired (step 105). The control unit 50 determines whether or not the acquired value has reached a preset upper limit value (step 106). When it has not reached, it returns to step 101 and water flow is continued, and when it reaches the set upper limit value, it proceeds to the water changing process after step 110. When a TOC meter is used for the transition from the water flow process to the water change process, the upper limit value of the TOC meter is based on the quality of drinking water, for example, 5 mg / L, which is the standard for tap water quality, and is safe. A value smaller than this is set in consideration. Moreover, when an electrical conductivity meter is used for the transition from the water flow process to the water replacement process, the correlation between the TOC of the system water and the electrical conductivity is measured, and the upper limit value of the electrical conductivity meter is For example, the electrical conductivity is equivalent to TOC 5 mg / L. The actual upper limit value is, for example, 0.5 to 0.7 times the upper limit value in consideration of the fact that the electrical conductivity is not a direct water quality index such as TOC and safety. . By performing the control based on the information on the water quality, it becomes possible to perform the drainage control including the water changing process described later in a state where the water quality of the circulated water is almost accurately grasped.

  As described above, the measuring devices used for the transition from the water flow process to the water change process include the integrating flow meter 27, the water flow timer, the TOC meter, and the electrical conductivity meter, and one of these measuring devices is used. That's fine. However, it is also possible to combine the step (step 103 and step 104) of the integrated processing water amount and the step (step 105 and step 106) of water quality control shown in FIG. That is, a total flow meter 27 or a water flow timer and a TOC meter or an electric conductivity meter are used in combination as the water quality meter 25, and the water flow from the water flow process is determined by the signal from the measuring device whose indicated value reaches the set value first. It is also effective to configure so as to shift to a replacement process.

  Next, the water change process after step 110 is demonstrated. In the water change process, first, the first drain valve 28 is opened, and the system water is discharged outside the apparatus (step 110). At this time, the recovered raw water pump 26 is activated, and the water in the apparatus is discharged out of the apparatus from the drain valve installed in the activated carbon tower treated water pipe 33 (step 111). In addition, the 2nd drain valve 29 which is the activated carbon tower hot water sterilization drain valve installed in the collection | recovery raw water piping 32 can also be used for drainage. However, the drainage from the first drain valve 28 after passing through the activated carbon tower 22 is preferable in order to make the subsequent wastewater treatment unnecessary. Here, the process differs depending on whether the control method by the control unit 50 is control based on the accumulated drainage amount or water quality control (step 112). In the control based on the accumulated drainage amount, for example, a water amount 1.5 to 2.0 times the retained water amount in the system is discharged outside the apparatus. The control unit 50 observes the integrated flow meter 27 and acquires the integrated drainage amount (step 113). Then, it is determined whether or not the acquired accumulated drainage amount has become a preset value stored in the memory (step 114). If the set value has not been reached, the flow returns to step 111 to continue draining. When the predetermined amount of water is discharged, the first drain valve 28 (or the second drain valve 29) is closed (step 117), the recovery raw water pump 26 is stopped, the water changing process is completed, and the flow process is started. To do. On the other hand, when water quality control is performed in step 112, the value of the water quality meter 25 including a TOC meter and an electrical conductivity meter is acquired, and the quality of the recovered raw water is measured (step 115). Then, it is determined whether or not the value of the water quality meter 25 has become a preset value stored in the memory (step 116). When it has not reached, it returns to step 111 and a water change process is continued. When the TOC and electrical conductivity of the recovered raw water reach the respective set values, the water change process is terminated, and the process proceeds to step 117 and then proceeds to the water flow process. In addition, the set value at the end of the water changing process of the TOC meter or the electrical conductivity meter is set to a value of about 1.5 times the TOC of the makeup water and the electrical conductivity, for example.

Next, the hot water cleaning process will be described.
There are two major hot water cleaning processes. The first hot water washing step is a step of washing the cartridge filter 23 with hot water. The supplied hot water washing water is heated by the heat exchanger 24 to become hot water, which is introduced into the cartridge filter 23 through a hot water supply valve (not shown) attached to the cartridge filter treated water pipe 34, and activated carbon tower The water is discharged from the first drain valve 28 attached to the treated water pipe 33 to the outside of the apparatus. This first hot water washing step is performed about once per day to prevent the cartridge filter 23 from being blocked by pulverized coal.

The second hot water cleaning step is a step of performing hot water cleaning of the cartridge filter 23 and the activated carbon tower 22. In this second hot water cleaning step, the same hot water as that used in the first hot water cleaning step is introduced into the cartridge filter 23 from a hot water supply valve (not shown) attached to the cartridge filter processing water pipe 34. To do. Further, this hot water is introduced into the activated carbon tower 22 from the bottom of the activated carbon tower 22 through the activated carbon tower treated water pipe 33, and a second drain valve (activated carbon tower hot water sterilization drain valve attached to the recovered raw water pipe 32 is used. ) The product is discharged from the device 29. The frequency of the second hot water washing step is determined by the concentration of the acetic acid component brought from the aseptic filling equipment rinser 10, but in the case of a low concentration, it is performed once per week. In this second hot water washing step, acetic acid adsorbed on the granular activated carbon of the activated carbon tower 22 is desorbed and discharged out of the apparatus, so that the acetic acid adsorption capacity of the granular activated carbon is recovered and the increase in TOC of the system water is suppressed. The water change frequency can be reduced. For this reason, as the hot water washing water supplied to the rinser drainage recovery apparatus 20, demineralized water having a lower component concentration than clean water, for example, ion exchange treated water having an electric conductivity of 1 mS / m at 25 ° C. or less is preferable.
In the first hot water washing step and the second hot water washing step, hot water of 60 to 90 ° C. can be applied. In order to perform effective washing, hot water discharged after hot water washing is used. It is preferable to maintain the temperature at 80 ° C. or higher for about 30 minutes.

  As described above in detail, in the present embodiment, the treatment by the activated carbon tower 22 and the cartridge filter 23 and the water quality meter 25 such as the cumulative amount of water treated by the cumulative flow meter 27, the water flow timer, or the TOC meter / electric conductivity meter. By controlling the water quality, the rinser drainage containing peroxide can be treated into potable water, collected in the aseptic filling equipment rinser 10 and reused. Further, by washing the cartridge filter 23 and the activated carbon tower 22 with hot water, it becomes possible to recover the acetic acid adsorption ability of the activated carbon in addition to the suppression of bacterial growth in the apparatus, and to reduce the frequency of disposal of the system water. it can. And according to this Embodiment, the peroxide containing waste_water | drain discharged | emitted from the aseptic filling equipment rinser 10 can be stably processed with the activated carbon tower 22 and the cartridge filter 23, is compact, and operation management is easy. A more economical rinser drainage recovery device 20 can be realized. This makes it possible to save water resources by reducing the amount of water used and to reduce the load on the water environment by reducing the amount of drainage.

  The present invention can be applied to, for example, a rinser drainage recovery apparatus for an aseptic filling facility, a rinser drainage recovery system provided with a rinser, and the like.
