Description

Monitoring system for ballast water of a ship by a quantitative analysis}

The present invention is installed by inserting a conical filter for condensing the microorganisms contained in the ballast water into the sampling tank, the lower side of the sampling tank is installed a sensing chamber for storing the extract water concentrated microorganisms through the filter, On the lower side of the sensing chamber, a microbial detector capable of measuring the distribution of microorganisms and the number and killing of microorganisms is installed, and a portion of the ballast water supplied to the filter is distributed to a concentrated filtration tank and a raw water storage tank, while in the concentrated filtration tank. By concentrating even microorganisms of microscopic size that cannot be concentrated in the filter of the sampling tank and storing the ballast water in which the microorganisms are not removed, the raw water storage tank, together with the individual quantitative analysis of the concentrated microorganisms in the filter of the sampling tank The basic sample is the ballast water of the raw water storage tank. Through the quantitative analysis using the filtered water of the concentrated filtration tank instead of the microbial extract water as a control, the quantitative analysis and monitoring system of the ship's ballast water was able to measure the distribution and population of various microorganisms contained in the ballast water more quickly and accurately. It is about.

In general, ballast water is installed on both sides of the bottom of a ship so that the ship can be prevented from being out of balance when the cargo is unloaded from the vessel or when the vessel is operated in a state where the amount of cargo loaded on the vessel is very small. Means freshwater or seawater for buoyancy adjustment to be filled in the ballast tank.

Such ballast water contains various microorganisms such as pathogenic bacteria and plankton contained in freshwater or seawater filled with ballast water. Therefore, if it is discharged into the water of another region without any treatment, serious marine pollution And the destruction of ecosystems.

Based on this situation, in 1996, in the United States, the national invasive species law was enacted, requiring the management and control of the ballast water by stipulating the exotic species as the intruder. In Australia, the quarantine law was amended to import the ballast water As well as direct quarantine.

On the other hand, the International Maritime Organization (IMO) concluded an international agreement in February 2004, and from 2009, the ship was required to install the necessary equipment for the sterilization and purification treatment of ballast water sequentially. In case of violation, Of the total number of vessels.

Accordingly, various techniques for treating ship ballast water have recently been developed, and a representative example thereof is sterilization and purification treatment of ballast water using ozone (O ₃ : 0 ₃ ). In addition, Ballast water purifiers have been developed or are under development.

Since the ballast water purification device mounted on the vessel as described above undergoes land test and on-board test in accordance with the standards of the International Maritime Organization (IMO) and the Ministry of Land, Transport and Maritime Affairs, and then the certificate of approval is carried on the ship. In addition, a system is needed to monitor whether the ballast water treated by the ballast water purification system complies with the emission standards set by the International Maritime Organization and the Ministry of Land, Transport and Maritime Affairs.

As a representative example of the sampling system for monitoring the ballast water as described above, as described in Korean Patent Publication No. 2010-103487 (published date: September 27, 2010), to concentrate the microorganisms contained in the ballast water And a sampling system in which a conical filter is inserted into a sampling tank, and a storage container for storing extract water in which microorganisms are concentrated through a filter is installed at a lower side of the sampling tank.

According to the conventional sampling system as described above, the microorganisms are trapped on the inner surface of the filter in the process of introducing and discharging the ballast water through the sampling tank, and thus by rinsing to wash off the microorganisms trapped on the inner surface of the filter. The extract water for the sample is stored in the storage container, and the above operation is repeated several times to obtain the required amount of extract water, and then the storage container is separated from the sampling tank to measure the distribution or population of microorganisms contained in the extract water. You can do it.

However, the conventional sampling system as described above separates the storage container in which the sample water is stored from the sampling tank and transports the storage container to a laboratory equipped with measuring equipment, and then distributes or populations of microorganisms contained in the sample water. Since the back to be measured in the laboratory, there was a problem that unnecessary time and manpower was wasted in monitoring the ballast water.

In particular, during the time that the sample extract water is stored in the storage container through several repetitive processes, there is a problem in that the distribution or population of microorganisms contained in the extract water cannot be measured in real time. In addition, since it is not possible to accurately determine whether or not the killing of microorganisms, it is difficult to determine whether the killed microorganisms are caused by a purification device or other external factors.

As described above, it is difficult to accurately measure the distribution, population, and death of microorganisms contained in the ballast water in real time by the conventional sampling system, so that the ballast water purification device mounted on the ship operates at a level suitable for the emission standard. In addition, since it becomes uncertain, there is a problem that efficient feedback control of the ballast water purifier based on the monitoring result is difficult.

In addition, according to the conventional sampling system, by using a rinse mechanism installed inside the filter during the rinsing operation of washing the microorganisms trapped on the inner surface of the filter to the storage container side, the recovery of microorganisms caught in the filter network As well as not easy, microorganisms are constantly attached to the surface of the filter even during the rinsing process, which causes the rinsing operation of the filter is not smoothly performed, the clogging phenomenon of the filter often occurs, concentrated in the filter There was a problem that additional and complex monitoring of microorganisms could not be achieved.

In order to solve the above problems, the microorganism detector is installed on the lower side of the sensing chamber while the storage chamber of the sample extract water is used as the sensing chamber, and the ballast water is used by using two sampling tanks. By extracting microorganisms (animal plankton) of 50 μm or more contained in each and microorganisms (phytoplankton) of 10 μm or more from less than 50 μm in size, and storing them in a corresponding sensing chamber and monitoring them with a microbial detector, the ballast water The system for monitoring the ballast water for ships, which was able to secure various and complex data on the result of the processing, was filed by the applicant in 2011 patent application No. 19574.

However, even in the case of the monitoring system pre- filed by the applicant, the filtered water passing through the primary filter is sent to the secondary filter, so that microorganisms in the range of 10 μm to less than 50 μm that are not concentrated in the primary filter are added in the secondary filter. As a result of the concentrating, the process of obtaining the required amount of extract water from the secondary filter and storing it in the sensing chamber has a relatively long processing time and a difficult rinsing operation.

In other words, the mesh of the filter network provided in the secondary filter is formed into a very fine hole to concentrate the microorganisms of 10 μm level, so that the filtered water introduced into the secondary filter through the primary filter performs the concentration process of the microorganisms. In addition, the time taken to completely exit through the secondary filter is relatively long, and the rinsing operation of the secondary filter using the rinsing mechanism also requires longer processing time and more demanding processing than the primary filter due to the fine filtration hole. .

Therefore, it was possible to reduce the time and expense required to monitor the ballast water, and to secure various data, compared to the conventional method, but the time and cost required for the monitoring of the ballast water was unnecessarily wasted according to the application of the secondary filter. This has led to the need for improvement measures that enable faster, more accurate, more economical and more rational monitoring to be carried out, while maintaining the advantages of an earlier application.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

In the case of the quantitative analysis monitoring system 100 for ship ballast water according to the present invention, as shown in FIGS. 1 to 3, the conical filter 2 for concentrating microorganisms contained in the ballast water is also sampling tank ( It is installed on the basis of the sampling device 10 is installed in the interior of the 1, the sensing chamber (8) is installed in the lower side of the sampling tank (1) through the filter (2) to store the extraction water concentrated microorganisms do.

The upper end portion of the filter 2 is provided with an upper reinforcing frame 2a for maintaining the shape of the inlet of the filter 2 while the lower end of the filter 2 is connected to the sampling tank 1). However, it goes without saying that the filter 2 may be installed inside the sampling tank 1 by using various other methods.

The filter 2 is usually a fabric (cloth) using a material such as nylon or a non-woven filter cloth is used, but in some cases may be used to form a stainless steel metal mesh in a conical shape, to the filter (2) The size (μm) of the microorganisms to be concentrated depends on the size (Mesh) of the filtration hole provided in the filter 2, and in the present invention, the size of the microorganism (animal plankton) having the size of 50 μm or more of the filter 2 is determined. Use as a primary filter for concentration.

The sampling tank 1 is usually a cylindrical tank using stainless steel, the inlet pipe 12 of the ballast water is connected to the upper end surface of the sampling tank 1, the bottom side of the sampling tank (1) The discharge pipe 13 of the filtered water passing through the filter (2) is installed, the inlet pipe 12 is provided with a main valve 16 and a flow meter (17) for the quantitative input of ballast water.

In order to close the main valve 16 installed in the inflow pipe 12, the main valve 16 is preferably an automatic control electric valve.

The inlet pipe 12 is branched from a ballast water pipe not shown to supply ballast water to a ballast tank for ships through a ballast water purification device, and as shown in FIG. 3, a main valve 16 and a flow meter 17 are installed. It is preferable to additionally install a manual valve mechanism (V) in the inlet pipe (12) at the previous position on the basis of the position, and the main valve (16) and the flow meter (17) are important parts in terms of the operation of the system. Therefore, it is preferable to insert the inside of the device case 30 to protect it safely.

The sensing chamber 8 is connected to the lower end of the strainer 2 by a water pipe 7 having a valve mechanism V in a state of being positioned at the lower side center of the sampling tank 1, The lower end of the strainer 2 to which the water pipe 7 is connected is formed of a pipe-shaped lower end collecting part 3 for convenience of piping connection and primary collecting of extracted water.

The lower collecting part 3 is most preferably installed in the bottom side of the sampling tank 1 so as to communicate with the lower outlet of the filter 2, but the lower end of the pipe shape at the lower end of the filter 2. In a state in which the collecting part 3 is integrally formed, the lower collecting part 3 may be installed to penetrate the bottom surface of the sampling tank 1, and the inner bottom of the lower collecting part 3 is a water collecting pipe. When opening the valve mechanism V of (7), it is preferable to form it with the funnel bottom so that the sample extract water may not remain.

In FIG. 1, a drain pipe having a valve mechanism is installed to discharge the filtrate directly below the lower collecting part 3, but the sensing chamber 8 may be connected to the valve mechanism V without installing the drain pipe. In the process of separating from the collection pipe (7) together with the discharge of the filtrate can be carried out, the sensing chamber 8 is also preferably a stainless steel container, but other corrosion-resistant materials can be applied, of course to be.

The sensing chamber 8 may be formed as an empty conical container as in the prior art and a microbial detector 9 may be installed at a lower vertex of the conical sensing chamber 8 so that the sensing chamber 8 8 is most preferably included in the detection range of the microbial detector 9 and the microbial detector 9 is disposed in the sensing chamber 8 with a watertight sealing ring therebetween. In the fastening manner.

The microbial detector 9 may be used to install any kind of microorganisms in the sample water concentrated in the filter 2, that is, the distribution and population of animal plankton that is 50 µm or more, and whether or not to kill. The most preferred is a Fluorescence-activated cell sorting (FACS) module capable of continuous real-time monitoring, a dynamic light scattering (DLS) sensor, or a light emitting diode (LED) / photodiode (PD) type optical detector. It is connected to the detection monitor of a monitor room (ship room, steering room, laboratory etc.).

In addition, a method of outputting the data measured by the microorganism detector 9 to the detection monitor of the monitor room can be applied in a wide variety of ways. For example, size filtering, object extraction, It is used for object measurement, pattern matching, pattern recognition, sensor data monitoring, log data recording, calibration method, data conversion Conversion) can be included.

The microbial detector 9 is installed at the lower end of the conical sensing chamber 8 in which the extract water for the sample condensed with the microorganisms in the filter 2 is stored, and the microbial detector 9 is connected to the detection monitor of the monitor room. When connected, the extraction chamber for the sample is stored in the sensing chamber 8, so that the distribution of the microorganisms contained in the extract water, the number of individuals, and whether or not to die can be accurately measured in real time.

Therefore, the time and cost required for the sample measurement can be minimized by eliminating the troublesome operation of transporting the sensing chamber 8 to the laboratory, and the state of the microorganism can be maintained at any time in the sensing chamber 8 And more reliable data can be provided. Also, a method of rotating the conical sensing chamber 8 in a state where the conical sensing chamber 8 is inclined by a predetermined angle as in the prior art can be applied.

As a component constituting the first main part of the monitoring system 100 according to the present invention, a sampling pipe 21 of ballast water is connected to the inlet pipe 12, and the sampling pipe 21 is a valve mechanism (V). While branched into two distribution pipes 22 having a), each distribution pipe 22 is divided into a concentrated filtration tank 23 and a raw water storage tank 26 and installed, and the concentrated filtration tank 23 and a raw water storage tank. Intake lines 25 and 27 are respectively extended from the inside of the 26, and each of the intake lines 25 and 27 are connected to the detection chamber 29 via the metered discharge pump 28. will be.

Even more preferably, the sampling pipe 21 is connected to the inlet pipe 12 at the position before the main valve 16 and the flow meter 17 is installed, as shown in the enlarged portion of FIG. The inlet side of the sampling pipe 21 is inserted into the inlet pipe 12 through the inlet pipe 12, and then the inlet pipe 12 and a predetermined length in a direction facing the inlet direction of the ballast water. It is intended to extend in parallel.

When the inlet side of the sampling pipe 21 is installed in the inlet pipe 12 in the same manner as described above, a part of the ballast water supplied to the filter 2 of the sampling tank 1 through the inlet pipe 12 is provided. It provides a more advantageous advantage in that it smoothly flows into the concentrated filtration tank 23 and the raw water storage tank 26 through the sampling pipe 21 and the distribution pipe 22, and the inlet part of the inlet is about 45 degrees. It is even more preferable to cut obliquely upward at an angle of.

In addition, a concentrated filter 24 is inserted into the concentrated filter tank 23, and the concentrated filter 24 is a microorganism having a size of 10 μm that cannot be concentrated in the filter 2 of the sampling tank 1. Phytoplankton) is a filter that can be concentrated, the inlet of the intake line 25 for the concentrated filter tank 23 is disposed in the lower portion of the outer side of the concentrated filter 24, the concentration according to the operation of the quantitative discharge pump 28 The filtered water passing through the filter 24 is supplied to the detection chamber 29.

As described above, in the monitoring system 100 of the present invention, a part of the ballast water supplied to the filter 2 of the sampling tank 1 is distributed to the concentrated filtration tank 23 and the raw water storage tank 26, and the concentrated filtration tank ( In the concentrated filter 24 of 23), the microorganism having a size of 10 μm that cannot be concentrated in the filter 2 of the sampling tank 1 is concentrated, and the ballast water in which the microorganism is not removed is stored in the raw water storage tank 26. Next, the filtered water passed through the concentrated filter 24 and the ballast water of the raw water storage tank 26 are supplied to the detection chamber 29 by the quantitative discharge pump 28.

Through the improvement of the monitoring method as described above, the microbial concentrated extract water in the filter 2 of the sampling tank 1 is used as a sample for quantitative analysis of zooplankton, while the ballast supplied from the raw water storage tank 26. Using the water as a basic sample and the filtered water passed through the concentrated filter 24 instead of the microbial extract water as a control, it is possible to measure the distribution and population of various phytoplankton contained in the ballast water by quantitative analysis.

That is, the microorganism of 50 μm or more extracted from the filter 2 of the sampling tank 1 is individually quantitatively analyzed using the microbial detector 9 in the sensing chamber 8, and the ballast supplied from the raw water storage tank 26. By measuring the number in the detection chamber 29 to calculate the microbial value of less than 50㎛, and the filtered water discharged through the concentrated filter 24 is measured in the detection chamber 29 to calculate the microbial value of less than 10㎛ On the other hand, by subtracting the microbial value of less than 10㎛ from the microbial value of less than 50㎛, the quantitative analysis of the method of calculating the microbial value of less than 50㎛ and 10㎛ or more in parallel.

By applying the quantitative analysis method to calculate the microbial value of less than 50 ㎛ and more than 10 ㎛ using the filtered water discharged through the concentrated filter 24 as a control as described above, from 10 to 50 ~ less than 50 ㎛ zooplankton The microorganisms are concentrated and extracted in the concentrated filter (24) by using the concentrated filter (24) as a secondary filter to secure various microorganism data necessary for the monitoring of ballast water, up to phytoplankton and phytoplankton of less than 10 µm. Compared to the monitoring method of the previous application, which is then measured by the microbial detector 9, monitoring in a more rapid, accurate, economical and rational manner becomes possible.

In other words, in the case of the prior application, a relatively long processing time and a demanding rinsing operation were required in the process of obtaining the required amount of extracted water from the concentrated filter 24 and storing it in the sensing chamber. By using coarse filtrate as a control, the extraction of microorganisms, which require a relatively long time, and the difficult rinsing required for them are eliminated.

In addition, since the rinsing mechanism of the filter 2 is provided only inside the sampling tank 1, and there is no need to install a separate rinsing mechanism inside the concentrated filtration tank 23, the configuration of the concentrated filtration tank 23 is very simple. Of course, since the plumbing equipment for supplying the rinsing water can be built much simpler than in the case of the previous application, it can greatly contribute to the reduction of time and cost according to the equipment of the monitoring system 100. will be.

In the monitoring system 100 according to the present invention, the detection chamber 29 for measuring the microorganisms in the ballast water discharged from the raw water storage tank 26 and the filtered water discharged from the concentrated filtration tank 23 is a microorganism of the sensing chamber 8 Of course, the detector mechanism of the various methods as mentioned in the section describing the detector 9 can be used, as well as the detection chamber 29 in the same manner as the sensing chamber 8 to form the distribution and population of microorganisms and It is also possible to monitor the killing in real time.

However, the difference is that the microorganism detector 9 for the sensing chamber 8 of the primary filter 2 measures the zooplankton of 50 μm or more, whereas the detection chamber 29 includes the ballast water and the filtered water. The phytoplankton of less than 50 μm or less than 10 μm is measured so that the phytoplankton can detect the number of chlorophyll (chlorophyll) in the body for photosynthesis, etc. This applies.

In addition, the quantitative discharge pump 28 is installed in a 2-way method so that the correct amount of the ballast water and the filtration water used as the basic sample and the control to each detection chamber 29, if necessary, quantitative discharge pump Instead of (28), it is also possible to install a motor pump controlled by a flow meter in the intake lines 25 and 27, and any device or apparatus capable of quantitatively supplying ballast water and filtered water may be used.

On the other hand, the filtered and ballast water stored in the concentrated filtration tank 23 and the raw water storage tank 26 may be supplied to the detection chamber 29 by a pumping method, and if necessary, the concentrated filtration tank 23 and the raw water storage tank ( Using the drain pipes 23a and 26a installed at the bottom of 26), the ballast water and the filtered water samples are directly collected, and then the existing method of transporting the sample to the monitor room equipped with the experimental apparatus is also applicable.

In FIG. 4, the structures of the concentrated filter tank 23 and the raw water storage tank 26 are shown in more detail. The concentrated filter 24 installed inside the concentrated filter tank 23 also includes the filter 2 of the sampling tank 1. It is installed in the conical shape using the same material as), and the filter support (24a) for firmly mounting the concentrated filter 24 inside the concentrated filter tank 23 is installed at the upper end of the concentrated filter (24). .

The strainer support (24a) with a function to firmly support the concentrated filter (24), the ballast water introduced from the distribution pipe (22) to flow over the interior of the concentrated filter tank (23) without passing through the concentrated filter (24) The partitions that block, that is, the reinforcement borders and flanges for the water line, also play a role.

In addition, the raw water storage tank 26 is a cylindrical storage tank of the empty state, a plurality of pipes along the height direction of the raw water storage tank 26 in the intake line 27 inserted into the raw water storage tank 26. The type inlet is provided, which is to discharge the ballast water stored in the raw water storage tank 26 evenly at various positions without biasing the specific position.

In other words, if only one inlet is formed in the intake line 27 inserted into the raw water storage tank 26, only the ballast water of a specific portion adjacent to the inlet is taken as a sample, so that the standard sample is uniform throughout the ballast water. Since it is difficult to obtain, by forming a plurality of inlets in the intake line (27) inserted into the raw water storage tank (26), to obtain an even standard sample throughout the ballast water stored in the raw water storage tank (26) will be.

Even more preferably, a plurality of pipe-shaped inlets are formed along the height direction of the water intake line 27 inserted into the raw water storage tank 26, and the length and length thereof from the lower side to the upper side of the raw water storage tank 26 are increased. The diameter is formed to be small, and each inlet tip and the inlet tip of the intake line 25 for the concentrated filtration tank 23 is also cut inclined upward at an angle of about 45 degrees.

When the inlet port of the intake line 27 for the raw water storage tank 26 is formed in the above manner, the suction force generated in the quantitative discharging pump 28 can act almost uniformly for each inlet port, and the position of each inlet port. It can also be arranged at different positions along the height direction, providing a further advantage in terms of obtaining even standard samples.

In the drawing, three inlets formed of a lower inlet 27a, an intermediate inlet 27b, and an upper inlet 27c along the height direction of the intake line 27 are installed, and as the number of inlets increases, Although advantageous in terms of obtaining a standard sample, there is a disadvantage in that the production and installation of the intake line 27 is difficult, it is preferable to apply an appropriate number of inlets in accordance with the capacity of the raw water storage tank (26).

In addition, drain pipes 23a and 26a provided with a valve mechanism V are provided at the lower ends of the concentrated filtration tank 23 and the raw water storage tank 26, and separate tanks as shown in FIGS. 2 and 3 are provided. It is installed adjacent to the device case 30 of the sampling device 10 by using the table 31, and, if necessary, the water level level sensor is installed inside the concentrated filtration tank 23 and the raw water storage tank 26 to distribute the pipe ( Note that it is also possible to automatically control the valve mechanism V of the 22 and the drain pipes 23a and 26a.

On the other hand, in Figures 2 and 3, the auxiliary tank 26 'is additionally installed together with the concentrated filtration tank 23 and the raw water storage tank 26, the auxiliary tank 26' is also sampling piping (21) In addition to the sampling pipe 21 is installed by another distribution pipe 22 branching from the other side, while not shown drain pipe with a drain valve is installed at the bottom of the tank.

The auxiliary tank 26 'further stores a predetermined amount of ballast water, and if necessary, drains the ballast water into a drain pipe so that the auxiliary tank 26' can be used for measurement of bacteria or another sample. In this way, the intake line can be extended to connect with another measuring device capable of measuring bacteria.

The concentrated storage tank 23, the raw water storage tank 26 and the auxiliary tank 26 'is also preferably manufactured using a stainless steel material such as SUS 316 excellent in corrosion resistance, and excellent adhesion and chemical resistance In addition, it is also possible to manufacture using a synthetic resin, for example, acetal, etc., which can produce a sealed container having no assembled surface or a seamless.

Still another aspect of the present invention is a rinsing mechanism for rinsing the filter 2 and a rinsing pipe in the form of a ring surrounding the filter 2, as shown in FIG. 1 more clearly as an improvement of the rinsing method. A plurality of 6 nozzles are arranged over the height direction of the filter 2, while a plurality of washing nozzles 4 are provided on the inner circumferential surface of each of the rinsing pipes 6, thereby providing a rinsing mechanism.

In addition, the rinsing pipe 6 is connected to the washing water injection pipe 15a extending from the rinsing pump 15 to supply the filtered or fresh water to the washing water, and each of the rinsing pipes 6 is connected to the pipe 5. By forming the washing water injection passage communicating with each other by, the washing water supplied from the rinsing pump 15 through the washing water injection pipe 15a is sprayed to each washing nozzle 4 to perform the rinsing operation of the filter 2. It becomes possible.

The rinse operation is performed by injecting filtered water onto the surface of the filter 2 to perform concentration of the microorganisms through the lower collecting section 3. The flow of ballast water into the sampling tank 1 → the concentration of microorganisms in the filter 2 And discharging the filtered water → storing the filtered water → rinsing (two to three times) the filter 2 using the filtered water and storing the extracted water in the sensing chamber 8 → final drainage of the filtered water constitutes one cycle, Is repeated several times.

When the rinsing operation of the filter 2 is performed in a state in which a plurality of ring-shaped rinsing pipes 6 provided with the cleaning nozzles 4 are arranged on the outer side of the filter 2 along the height direction as described above, The washing water injected from the nozzle 4 drops the microorganisms attached to the inner surface of the filter 2 from the surface of the filter 2 and the microorganisms thus removed fall along the inner space of the filter 2 to the bottom collecting part 3, So that an ideal sampling operation can be realized.

In order to more efficiently perform the rinsing operation of the filter 2 as described above, a plurality of tension cylinders 18 on the upper periphery of the sampling tank 1 are attached to the sampling tank 1. It is installed vertically downward based on the fixed cylinder bracket (1a), the piston rod (18a) of the tension cylinder 18 is connected to the upper reinforcing frame (2a) portion of the filter (2).

Accordingly, during the rinsing operation of the filter 2, the tension cylinder 18 may be operated to spray the washing water to the outer surface of the filter 2 while pulling the filter 2 upward. The microorganisms adhered to the surface of the filter 2 are highly eliminated while the filter 2 made of cloth is prevented from being deformed into the interior by the injection pressure of the washing water or its shape is deformed. As it is made smoothly, not only the rinsing operation of the filter (2) but also the final washing operation of the filter (2) using fresh water can be performed quickly and accurately.

Even more preferably, a plurality of ring-shaped rinsing pipes 6 surrounding the filter 2 are arranged over the height direction of the filter 2, with each rinsing pipe 6 being connected to the surface of the filter 2. Spaced at regular intervals so as to be arranged in the same conical shape as the filter (2).

When the respective rinsing pipes 6 are arranged in the same conical shape as the filter 2 as described above, the cleaning nozzles 4 provided for each of the rinsing pipes 6 and the outer surface of the filter 2 are located at the same distance The injection pressure of the washing water is evenly distributed from the upper end side to the lower end side of the strainer 2, so that the washing operation and the final washing operation can be performed more smoothly.

In the above case, the washing water in which the upper side rinsing pipes 6, except for one to two rinsing pipes 6 disposed on the lower side of each rinsing pipe 6, communicate with each other by the connecting pipes 5. In order to form an injection passage, one to two rinse pipes 6 arranged on the lower side are formed as separate washing water injection passages separated from the upper rinsing pipe 6, and then the rinsing pump 15 It is also possible to extend the two washing water injection pipes 15a provided with the valve mechanism V to be connected to the upper rinsing pipe 6 and the lower rinsing pipe 6, respectively.

When the supply of the washing water through the upper side rinsing pipe 6 and the lower side rinsing pipe 6 is made to be the same in the above-described manner, all of the valve mechanisms V provided in the two washing water inlet pipes 15a are opened, It is also possible to perform a rinsing operation on the entire surface of the filter 2 and to open only the valve mechanism V of the washing water inlet 15a for the lower side rinsing pipe 6, And can be independently performed.

Therefore, it is possible to separately perform the rinse operation at the lower end of the strainer 2 where the microbes are adhered in a large amount and the processing load becomes relatively large, while the supply of the wash water through only the corresponding site can be performed independently. Therefore, the rinsing operation at the lower end of the strainer 2 can be performed quickly and efficiently, thereby enhancing the concentration performance of the microorganism.

The rinsing pipe 6 is arranged at a certain interval along the height direction of the filter 2 and the lower rinsing pipe 6 It is preferable to separate the cleaning nozzles 4 in the order of 7, 6, 5, 4, and 3 in the order of the number of the cleaning nozzles 4 and the number of the cleaning nozzles 4 Can be changed arbitrarily according to the dimensions and the capacity of the filter (2).

In addition, the tension cylinder 18 is installed at a total of three places by the cylinder bracket (1a) fixed to the upper end side of the sampling tank (1), which is the tensile force of the cylinder that pulls the filter 2 upwards It is to be distributed evenly over the upper reinforcing frame (2a) of the filter (2), it is preferable to install at least two places in accordance with the size or capacity of the filter (2).

Meanwhile, the wash water supplied to the rinsing pipe 6 and the washing nozzle 4 via the washing water injection pipe 15a stores the filtered water discharged through the filter 2 and the discharge pipe 13 in the filtered water storage tank 19. A, it is preferable to use this in the rinsing operation of the filter (2) by pumping it with a rinsing pump (15), the final washing operation of the filter (2) is a fresh water (fresh water) stored in the fresh water storage tank (19 ') rinsing pump ( It is preferable to use by pumping 15).

To this end, in the monitoring system 100 of the present invention, the tank case 20 having the filtered water storage tank 19 and the fresh water storage tank 19 'is disposed at the bottom of the sampling tank 1, and the discharge pipe of the filtered water ( 13 is extended to the filtered water storage tank 19 in a state connected to the bottom of the sampling tank 1, the two washing water suction pipes (15b) extending from the rinsing pump (15) with a valve mechanism (V) Separately inserted into the filtered water storage tank 19 and the fresh water storage tank 19 'are installed.

In addition, the filtered water storage tank 19 and the fresh water storage tank 19 'are inserted into the water tank case 20 in a state partitioned by the partition wall 19a, and the fresh water storage tank 19' has an efficient filter ( 2) a heater not shown for heating the fresh water is installed for the washing operation, and if necessary, the drain pipe 20a is installed to discharge the filtered water and the fresh water stored in the corresponding water tank, and the filtered water storage tank 19 The overflow pipe 20b is connected and installed in the upper part of ().

As shown more clearly in FIG. 3, the overflow pipe 20b is installed in two pipes, while one overflow pipe 20b passes through the valve mechanism V to the filtered water storage tank 19. When the two overflow pipes 20b are applied in this manner, the two pipes 20b can be quickly and smoothly discharged to the filtered water storage tank 19 while simplifying the pipe structure. Can be discharged.

Using the water tank case 20 provided with the filtration water storage tank 19 and the fresh water storage tank 19 'as an integrated unit at the lower portion of the sampling tank 1 as described above simplifies the piping installation and the overall installation volume of the system. Although it is advantageous in terms of reducing the volume, when the spatial condition is not allowed, the tank case 20 including the filtrate storage tank 19 and the fresh water storage tank 19 'is separated from the sampling tank 1 and sampled, as in the case of the previous application. It can also be installed in the place away from the tank 1.

In this case, the drainage pipe 13 of the filtered water extends from the bottom surface of the sampling tank 1 to a place where the watertight case 20 is installed, and the rinsing pump 15, the washing water inlet 15a and the washing water feeding inlet 15b May also be installed so as not to be exposed to the outside from the inside of the sampling device 10, or may be installed in a state exposed to the outside of the sampling device 10.

Finally, an overflow tank 11 having a height lower than that of the filter 2 is provided between the sampling tank 1 and the rinsing pipe 6, and the overflow tank 11 and the sampling tank 1 are provided. On the bottom surface of the sampling tank 1 corresponding to the auxiliary discharge pipe 14 extending to the filtered water storage tank 19 side is connected.

If the overflow tank 11 having a lower height than the strainer 2 and opening at the upper end is provided between the sampling tank 1 and the rinsing pipe 6 as described above, The space between the sampling tank 1 and the overflow tank 11 is a buffer that can buffer the difference in the flow rate even if there is a slight difference in the natural discharge flow rate of the filtered water through the discharge pipe 13 Space.

Therefore, even if the ballast water above the reference value (contents of the sampling tank) is excessively supplied to the sampling tank 1 within a short time due to a malfunction of the flow meter 17 installed in the inlet pipe 12, the filtered water passing through the filter 2 Since the first flow into the buffer space over the overflow tank 11 and then discharged through the auxiliary discharge pipe 14, unless the large amount of ballast water exceeding the total volume of the buffer space is not supplied excessively, the filter (2) Filtered water does not flow back to the inside of the filter (2).

As described above, since the filtered water passing through the filter 2 flows back to the inside of the filter 2, the situation of diluting the ballast water can be effectively blocked by the overflow tank 11, The reliability of the measured data can be further improved by excluding another factor that gives an error to the measurement data such as the distribution or the number of the microorganisms involved.

Like the sampling tank 1, the overflow tank 11 also preferably uses a stainless steel material, and minimizes the resistance according to the surface tension, so that the filtered water can be discharged to the buffer space as much as the excess ballast water flow rate. Preferably, the upper end of the overflow tank 11 is formed with a toothed portion, and the height of the overflow tank 11 is preferably about 4/5 of the height of the filter 2.
