2. Description of the Related Art Conventionally, in a water treatment apparatus that treats water to be treated such as domestic wastewater discharged from ordinary households and sewage such as industrial wastewater, a configuration is known in which the quality of treated water is constantly grasped using a water quality detection sensor. Especially for household water treatment equipment that accepts and treats domestic household wastewater, the frequency of maintenance and inspection is lower than that of factories (for example, once every four months). There is a high demand for monitoring fluctuations in water quality.
For example, Patent Document 1 below discloses a technique for transmitting water quality information detected by a sensor installed in a water treatment device to a central management device via a telephone line. According to this technology, although it is effective to continuously monitor the water quality of the water treatment device during normal operation, the transmission route of the water quality information from the sensor of the water treatment device to the central management device becomes considerably long, Moreover, there is a concern that the reliability of the water quality information may be reduced due to the occurrence of a communication failure or the like on the transmission path due to an increase in elements intervening on the transmission path. In view of this, a configuration in which a stationary display device connected to the sensor of the water treatment apparatus is installed in order to suppress the length of the transmission path as much as possible and ensure the reliability of the water quality information is conceived. However, in such a configuration using a stationary display device on site, it is effective to ensure the reliability of water quality information, but each water treatment device requires a dedicated display device. May be affected by the outdoor environment (for example, adverse effects due to corrosive gas, moisture, ultraviolet rays, etc.).

  An outline of a water quality management system 100 which is an embodiment of a “water quality management system” in the present invention is shown in FIG. 1. As shown in FIG. 1, the water quality management system 100 of the present embodiment is mainly configured by a water treatment device 101 and a water quality detection data communication unit 130. This water quality management system 100 can also be referred to as a “water treatment device” or a “water treatment system”.

  The water treatment apparatus 101 accommodates various purification treatment mechanisms in a water treatment tank (also referred to as “tank main body”) formed in a tank shape. This purification treatment mechanism is roughly divided into a contaminant removal tank 110, an anaerobic filter bed tank 112, a contact filter bed tank 114, a treated water tank 116, and a disinfection tank 118 from the upstream (left side in FIG. 1) corresponding to the order of the treatment steps.

In the water treatment apparatus 101 having such a configuration, water to be treated (also referred to as “drainage” or “sewage”) flowing into the water treatment tank through the inflow portion 102 is a contaminant removal tank 110, an anaerobic filter bed tank 112, After being sequentially purified in the contact filter bed tank 114, the treated water tank 116, and the disinfection tank 118, it is discharged to the outside of the water treatment tank through the discharge unit 103. In the present embodiment, the water to be treated in each tank and the water flowing in the process of treating the water to be treated are referred to as “water to be treated” or “water”.

  The contaminant removal tank 110 is a tank that performs a process of separating contaminants contained in the treated water from the treated water using solid-liquid separation means such as an inflow baffle (not shown). Performs liquid separation function. The anaerobic filter bed 112 is a treatment tank having a function of anaerobically treating (reducing) organic pollutants in the water to be treated. Typically, anaerobic microorganisms for anaerobically treating (reducing) organic pollutants are attached. The filter medium is filled with a predetermined amount of filter medium. This anaerobic treatment can reduce BOD and reduce sludge. The contact filter bed tank 114 is a treatment tank having a function of performing aerobic treatment and filtration treatment of water to be treated. The treatment water tank 116 is a treatment tank having a function of temporarily storing water before being transferred to the disinfection tank 118. The disinfection tank 118 is a treatment tank having a function of disinfecting water that has flowed from the treatment water tank 116. As this disinfection treatment, a chlorine disinfection treatment with a solid chlorine agent, an ozone treatment, a UV (ultraviolet ray) treatment, an electrolytic sterilization treatment, or the like can be used as appropriate. The water sterilized in the sterilization tank 118 is discharged to the outside of the water treatment apparatus 101. The contaminant removal tank 110, the anaerobic filter bed tank 112, the contact filter bed tank 114, the treated water tank 116, and the disinfection tank 118 constitute the “purification processing unit” in the present invention.

In the present embodiment, the water quality detection sensor 120 is immersed in the sterilization tank 118. The water quality detection sensor 120 is configured as a water quality detection sensor having a function of detecting (measuring) the quality of water before being disinfected and discharged. The water quality detected by the water quality detection sensor 120 includes pH, DO (dissolved oxygen), turbidity, transparency, SS (suspended suspended solid amount), BOD (biochemical oxygen demand), ultraviolet light (UV). One or more of absorbance and the like can be mentioned. This water quality detection sensor 120 corresponds to the “water quality detection sensor” in the present invention. Moreover, the water treatment apparatus 101 provided with this water quality detection sensor 120 comprises the "septic tank with a sensor" in this invention.
In the present embodiment, the water purified on the upstream side of the sterilization tank 118 is sterilized in the sterilization tank 118, thereby preventing the biofilm from adhering to the water quality detection sensor 120. . According to such a configuration, it is possible to prevent accurate water quality detection from being hindered due to biofilm adhesion to the detection unit of the water quality detection sensor 120.

The water quality detection data communication unit 130 is mainly composed of the relay box 140 and the communication terminal 150. The water quality detection data communication unit 130 may be configured by adding a central monitoring device 160 and a display 170 described later to the relay box 140 and the communication terminal 150.
The relay box 140 relays the water quality detection sensor 120 and the communication terminal 150. The relay box 140 is disposed outside the water treatment tank for convenience in FIG. 1, but is preferably disposed at the upper part in the water treatment tank. In the present embodiment, the connector 124 attached to the cable 122 of the water quality detection sensor 120 is configured to be connected to the connector 144 attached to the cable 142 of the communication terminal 150 by the relay box 140. Accordingly, the water quality detection data (detection information) detected by the water quality detection sensor 120 is transmitted to the communication terminal 150 via the cable 122, the relay box 140, and the cable 142.

  Further, the water quality detection sensor 120 is configured to be detachable from the connector 144 by a connector 124 of the cable 122. According to this configuration, in the event of a failure of the water quality detection sensor 120, the water quality detection sensor 120 can be disconnected from the connector 144 at the connector 124 and connected to another water quality detection sensor 120 to perform sensor replacement work. Is done.

  The communication terminal 150 is configured as a terminal that performs wireless communication with a centralized monitoring device (also referred to as “data management device” or “data server”) 160. This communication terminal 150 is installed outside the water treatment tank of the water treatment apparatus 101. This communication terminal 150 corresponds to the “communication terminal” in the present invention. The centralized monitoring device 160 is installed at a location separated from the water treatment device 101, and is configured as a device that concentrates water quality management (water quality monitoring) of a plurality of water treatment devices. The centralized monitoring device 160 is equipped with various processing functions such as data calculation processing, data storage processing, data display processing, and data printing processing. This centralized monitoring device 160 corresponds to the “monitoring device separated from the water treatment tank” in the present invention.

  Accordingly, the water quality detection data transmitted from the water quality detection sensor 120 to the communication terminal 150 is transmitted to the centralized monitoring device 160 by radio. Thereby, the water quality detection data by the water quality detection sensor 120 is appropriately processed and collected by the centralized monitoring device 160 and used for water quality management. If necessary, the communication between the communication terminal 150 and the centralized monitoring device 160 may be configured to be performed by a wired system (for example, a method using a telephone line or an optical cable) instead of the wireless system.

  In the present embodiment, during the normal operation of the water treatment apparatus 101, the water quality detection data detected by the water quality detection sensor 120 is continuously collected and monitored by the centralized monitoring apparatus 160, while at the time of maintenance inspection, It is configured to use a portable display device (display device 170 to be described later) that can check water quality detection data as needed on site and is easy to carry.

  Especially for household water treatment equipment that accepts and treats domestic wastewater, the frequency of maintenance and inspection is lower than that of factories (for example, once every four months). There is a high demand for monitoring fluctuations in water quality. Therefore, as in the present embodiment, by adopting a configuration in which the water quality before being discharged to the outside of the water treatment tank is constantly monitored by the water quality detection sensor, the state of the treatment performance of the water treatment apparatus 101 is grasped. For example, it is possible to quickly cope with the case where the processing performance deteriorates. As a result, the water quality before being discharged out of the water treatment tank can be maintained and managed in a desired state, and water quality management in consideration of the environment becomes possible. Further, the centralized management in the centralized monitoring device 160 is particularly effective for water quality management (water quality monitoring) of a water treatment device that is widely spread, such as a household water treatment device.

  Here, regarding a specific configuration of the water quality detection data communication unit according to the portable display device, first to third embodiments will be described with reference to the drawings.

(First embodiment)
2 and 3 show a water quality management system 100 including the water quality detection data communication unit 130 according to the first embodiment. In particular, FIG. 2 shows a state of the water treatment apparatus 101 during normal operation, and FIG. 3 shows a state of the water treatment apparatus 101 during maintenance inspection.

  In the water quality detection data communication unit 130 shown in FIG. 2, when the water treatment device 101 is in a normal operation, the connector 124 on the water quality detection sensor 120 side and the connector 144 on the communication terminal 150 side are connected (connected). Set to In this setting state where the connector 124 is connected to the connector 144, a transmission path from the water quality detection sensor 120 to the centralized monitoring device 160 via the communication terminal 150 is established. This transmission path constitutes the “first transmission means” in claims 1 and 2. On the other hand, the connector 124 on the water quality detection sensor 120 side is disconnected from the connector 172 on the display 170 side, and the transmission path from the water quality detection sensor 120 to the display 170 is blocked.

  The connector 124 on the water quality detection sensor 120 side here corresponds to the “sensor-side connector” in claim 2, and the connector 144 on the communication terminal 150 side corresponds to the “communication terminal-side connector” in claim 2. The connector 172 on the display 170 side corresponds to the “display device side connector” in claim 2. Although not described in detail, each of these connectors has a known connector structure (connection structure), and enables transmission of information between one side and the other side connected by the connector. .

  With such a set state, the quality of water discharged from the water treatment device 101 during normal operation can be collected and monitored continuously by the centralized monitoring device 160 or continuously at regular intervals. It becomes possible. In this setting state, the information “detected by the water quality detection sensor during normal operation of the water treatment device in the normal operation of the water treatment device is continuously transmitted to the monitoring device separated from the water treatment tank via the first transmission means”. A first step of continuously collecting information on the quality of the water transmitted and thereby discharged outside the water treatment tank by the monitoring device is performed.

  On the other hand, in the water quality detection data communication unit 130 shown in FIG. 3, the connector 124 on the water quality detection sensor 120 side is disconnected from the connector 144 on the communication terminal 150 side during the maintenance inspection of the water treatment apparatus 101, The display 170 is connected to the display 170. That is, the connector 124 on the water quality detection sensor 120 side is detachable not only from the connector 144 on the communication terminal 150 side but also to the connector 172 on the display unit 170 side. In this setting state where the connector 124 is connected to the connector 172, a wired transmission path from the water quality detection sensor 120 to the display 170 is established. This transmission path constitutes "second transmission means" in claims 1 and 2. On the other hand, the connector 124 on the water quality detection sensor 120 side is disconnected from the connector 144 on the communication terminal 150 side, and the transmission path from the water quality detection sensor 120 to the centralized monitoring device 160 is blocked. As a result, the water quality detection data is output to the display unit 170, and the water quality detection data and related information are displayed on the display unit 174. That is, in this embodiment, each transmission path in the first transmission unit and the second transmission unit can be selected exclusively or alternatively.

  With such a setting state, it is possible to appropriately check the quality of water discharged from the water treatment apparatus 101 at the time of maintenance and inspection at the site. In this setting state, the information “detected by the water quality detection sensor at the time of inspection of the water treatment device is transmitted to the portable display device via the second transmission means, and thereby the water treatment tank. A “second step of confirming the information on the quality of the water discharged to the outside by displaying it on the display device” is performed.

  The display unit 170 is configured as a single display unit including at least a display unit 174 that displays water quality detection data and information related thereto, and an operation unit 176 that performs key operations related to display on the display unit 174. The display 170 used for portable use is preferably configured to be rechargeable or battery-driven. This display 170 corresponds to the “portable display device” and the “single display” in the present invention. If necessary, an audio output function and a print output function can be further added to the display 170.

According to the water quality management system 100 of the present embodiment, the transmission means for transmitting the information detected by the water quality detection sensor 120 to the centralized monitoring device 160, and the information detected by the water quality detection sensor 120 are portable. By providing a transmission means for transmitting to the display unit 170, water quality detection information is continuously collected by the centralized monitoring device 160 during normal operation, and water quality management is performed. It is reasonable because the water quality can be confirmed by the portable display 170 in order to ensure reliability.
In particular, by using a portable (portable) display 170, the display for displaying the water quality detection data can be used for a plurality of water treatment devices, and the display is installed on the site. Since it is not a mold, the display device is not adversely affected by outdoor environments such as corrosive gas, moisture, and ultraviolet rays. In addition, since information detected by the water quality detection sensor 120 may be transmitted to the centralized monitoring device 160 as it is during normal operation and subjected to arithmetic processing, there is no need to add an arithmetic processing unit to the on-site terminal. No display part is required. In addition, when the contents of the arithmetic processing unit are modified or changed, the update work is complicated with the on-site stationary display, but it is updated by using a portable display as in this embodiment. The work can be simplified.
Further, when the display 170 is connected to the water quality detection sensor 120, the number of elements interposed on the transmission path between the display 170 and the water quality detection sensor 120 can be reduced. It is possible to improve the reliability of water quality information.

Here, FIG. 4 shows a situation where the operator W performs maintenance and inspection of the plurality of water treatment apparatuses 101 using a single portable display 170.
As shown in FIG. 4, in the water quality management system 100 of the present embodiment, a plurality of water treatment apparatuses 101 (four in total in FIG. 4) are configured to be installed in a plurality of predetermined regions, respectively. Each water quality information in the water treatment apparatus 101 is individually displayed on a single indicator 170 at the installation location of each water treatment apparatus 101. Therefore, when performing maintenance and inspection of a plurality of water treatment apparatuses 101 (in the “second step” in the present invention), the operator W carries a single indicator 170 and each water treatment apparatus 101. It is possible to check the water quality information in the water treatment apparatus 101 with a single indicator 170 while visiting the installation locations. Further, in this case, each transmission path in the first transmission means and the second transmission means can be selected exclusively or alternatively, and at the time of maintenance inspection of a plurality of water treatment devices 101, By selecting the transmission path in the second transmission means and performing only the display output to the single display 170, the output to the centralized monitoring device 160 can be omitted, which is reasonable.

(Second Embodiment)
5 and 6 show a water quality management system 200 including the water quality detection data communication unit 230 of the second embodiment. In particular, FIG. 5 shows a state of the water treatment apparatus 101 during normal operation, and FIG. 6 shows a state of the water treatment apparatus 101 during maintenance inspection.

  As shown in FIGS. 5 and 6, the water quality detection data communication unit 230 of the second embodiment is the same as the water quality detection data communication unit 130 of the first embodiment, and the communication terminal 150 further includes a connector 152. The connector 152 can be attached to and detached from the connector 172 on the display 170 side.

  In the water quality detection data communication unit 230 shown in FIG. 5, the connector 124 on the water quality detection sensor 120 side and the connector 144 on the communication terminal 150 side are set to be connected (connected). In this setting state where the connector 124 is connected to the connector 144, a transmission path from the water quality detection sensor 120 to the centralized monitoring device 160 via the communication terminal 150 is established. This transmission path constitutes "first transmission means" in claims 1 and 3. On the other hand, the connector 172 on the display 170 side is disconnected from the connector 152 on the communication terminal 150 side, and the transmission path from the water quality detection sensor 120 to the display 170 is blocked.

  Here, the connector 152 on the communication terminal 150 side corresponds to the “communication terminal side connector” in claim 3, and the connector 172 on the display 170 side corresponds to the “display device side connector” in claim 3. . Although not described in detail, each of these connectors has a known connector structure (connection structure), and enables transmission of information between one side and the other side connected by the connector. .

  With such a set state, the quality of water discharged from the water treatment device 101 during normal operation can be collected and monitored continuously by the centralized monitoring device 160 or continuously at regular intervals. It becomes possible. In this setting state, the information “detected by the water quality detection sensor during normal operation of the water treatment device in the normal operation of the water treatment device is continuously transmitted to the monitoring device separated from the water treatment tank via the first transmission means”. A first step of continuously collecting information on the quality of the water transmitted and thereby discharged outside the water treatment tank by the monitoring device is performed.

  In contrast, in the water quality detection data communication unit 230 shown in FIG. 6, the connector 124 on the water quality detection sensor 120 side and the connector 144 on the communication terminal 150 side are connected at the time of maintenance and inspection of the water treatment apparatus 101. In this state, the connector 172 on the display 170 side and the connector 152 on the communication terminal 150 side are connected (connected). In this setting state in which the connector 172 is connected to the connector 152, a wired transmission path from the water quality detection sensor 120 to the display 170 is established. This transmission path constitutes "second transmission means" in claims 1 and 3.

As a result, the water quality detection data is output to the display unit 170, and the water quality detection data and related information are displayed on the display unit 174. With such a setting state, it is possible to appropriately check the quality of water discharged from the water treatment apparatus 101 at the time of maintenance and inspection at the site. In this setting state, the information “detected by the water quality detection sensor at the time of inspection of the water treatment device is transmitted to the portable display device via the second transmission means, and thereby the water treatment tank. A “second step of confirming the information on the quality of the water discharged to the outside by displaying it on the display device” is performed.
On the other hand, the transmission path from the water quality detection sensor 120 to the centralized monitoring device 160 is maintained as in the normal operation. Therefore, the quality of the water discharged from the water treatment device 101 can be continuously collected and monitored continuously by the centralized monitoring device 160 or at regular intervals.

According to the water quality management system 200 of the present embodiment, the worker W uses a single portable display 170 to connect a plurality of water treatment devices 101 as in the water quality management system 100 of the form shown in FIG. Maintenance inspection is possible. In this case, transmission means for transmitting the information detected by the water quality detection sensor 120 to the centralized monitoring device 160, and transmission means for transmitting the information detected by the water quality detection sensor 120 to the portable display 170. By combining these, water quality detection information is continuously collected by the centralized monitoring device 160 during normal operation to manage the water quality, and at the time of maintenance inspection, a portable display is provided to ensure the reliability of the water quality detection information. It is reasonable because the water quality can be confirmed by the vessel 170.
In particular, by using a portable (portable) display 170, the display for displaying the water quality detection data can be used for a plurality of water treatment devices, and the display is installed on the site. Since it is not a mold, the display device is not adversely affected by outdoor environments such as corrosive gas, moisture, and ultraviolet rays. In addition, since information detected by the water quality detection sensor 120 may be transmitted to the centralized monitoring device 160 as it is during normal operation and subjected to arithmetic processing, there is no need to add an arithmetic processing unit to the on-site terminal. No display part is required. In addition, when the contents of the arithmetic processing unit are modified or changed, the update work is complicated with the on-site stationary display, but it is updated by using a portable display as in this embodiment. The work can be simplified.
Further, the operation is simplified because the connector 124 on the water quality detection sensor 120 side is not required only by attaching / detaching the connector 172 on the display 170 side to the connector 152 on the communication terminal 150 side.
Furthermore, since the connector 152 to which the connector 172 on the display 170 side is connected is provided in the communication terminal 150 installed outside the water treatment tank, the operation for connecting the connector 172 on the display 170 side to the connector 152 becomes easy.

In this setting state where the connector 124 is connected to the connector 144, a transmission path from the water quality detection sensor 120 to the centralized monitoring device 160 via the communication terminal 150 is established. This transmission path constitutes "first transmission means" in claims 1 and 4. On the other hand, the indicator 170 is in a preparation state where the start switch or the like is turned off or is separated from the communication terminal 150, and the transmission path from the water quality detection sensor 120 to the indicator 170 is blocked.

  With such a set state, the quality of water discharged from the water treatment device 101 during normal operation can be collected and monitored continuously by the centralized monitoring device 160 or continuously at regular intervals. It becomes possible. In this setting state, the information “detected by the water quality detection sensor during normal operation of the water treatment device in the normal operation of the water treatment device is continuously transmitted to the monitoring device separated from the water treatment tank via the first transmission means”.

The display 170 is maintained around the communication terminal 150 with the start switch and the like turned on. In this set state, a wireless transmission path from the water quality detection sensor 120 to the display 170 is established. This transmission path constitutes "second transmission means" in claims 1 and 4.

As a result, the water quality detection data is output to the display unit 170, and the water quality detection data and related information are displayed on the display unit 174. With such a setting state, it is possible to appropriately check the quality of water discharged from the water treatment apparatus 101 at the time of maintenance and inspection at the site. In this setting state, the information “detected by the water quality detection sensor at the time of inspection of the water treatment device is transmitted to the portable display device via the second transmission means, and thereby the water treatment tank. A “second step of confirming the information on the quality of the water discharged to the outside by displaying it on the display device” is performed.
On the other hand, the transmission path from the water quality detection sensor 120 to the centralized monitoring device 160 is maintained as in the normal operation. Therefore, the quality of the water discharged from the water treatment device 101 can be continuously collected and monitored continuously by the centralized monitoring device 160 or at regular intervals.
