[0002] The biological activated carbon filter process has the functions of ordinary rapid filter and activated carbon adsorption, and has a good effect on removing various zooplankton in the water. As a deep treatment technology, it has been widely used in domestic water treatment systems. The filler used in the activated carbon filter is activated carbon particles, which are conducive to the adhesion and growth of zooplankton. For the post-activated carbon filter, under suitable conditions, the risk of biological leakage in the filter is extremely high. Therefore, the activated carbon filter needs to clean the filter material through periodic backwashing and disinfect the micro-animals breeding in the lower area of ​​the filter bed.

[0003] For example, when biological problems arise during the operation of the activated carbon filter, the water treatment system will use disinfectant-assisted backwashing and disinfectant to disinfect the filter, but the triggering conditions cannot be automatically determined. Manual detection is required to check if the zooplankton in the effluent from the activated carbon filter exceeds the standard, or if the operator visually observes an increase in zooplankton in the filter, emergency filter disinfection treatment is required. Therefore, the disinfection of carbon filters in existing water treatment systems urgently needs to be controlled and operated intelligently. Utility Model Content

Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

Therefore, the directional terms used are used to illustrate and understand this application, but not to limit this application. In addition, in the drawings, structures with similar or identical structures are represented by the same reference numerals.

[0025] See also Figure 1 to Figure 2 , Figure 1 A schematic diagram showing a zooplankton disinfecting device of the present application being applied to a water treatment system. Figure 1 As shown, a zooplankton disinfecting device 20 shown in an embodiment of the present application can be applied to a water treatment system 10, and the water treatment system 10 includes a carbon filter 11 for filtering water. The zooplankton disinfecting device 20 includes a monitoring device 21, a disinfecting mechanism and a control unit; wherein the monitoring device 21 is connected to the carbon filter 11, and is used to obtain the effluent of the carbon filter 11 in real time to measure the zooplankton content in the carbon filter 11; the disinfecting mechanism is used to disinfect the zooplankton in the carbon filter 11; the control unit is used to control the disinfecting mechanism to disinfect the zooplankton according to the zooplankton content.

[0026] In this embodiment, the water treatment system 10 generally includes a carbon filter tank 11 for filtering water, and the disinfecting mechanism in this embodiment can be used to perform corresponding disinfecting treatment on the zooplankton in the filter tank; it can be known that the disinfecting mechanism in this embodiment is not limited to the disinfecting of the carbon filter tank 11, but can also be used for the disinfecting of other pools or mechanisms in the water treatment system 10 according to specific usage requirements; the monitoring device 21 can be used to detect the presence and content of zooplankton in the water, such as various zooplankton, etc.; the disinfecting mechanism can be set according to the disinfecting requirements of the zooplankton concentration.

[0027] In addition, a monitoring structure is also provided at the water outlet of the carbon filter tank 11, which is used to obtain the effluent of the carbon filter tank 11 in real time and measure the zooplankton content in the effluent water in time. By measuring the zooplankton in the effluent water of the carbon filter tank 11, the zooplankton content in the effluent water can be obtained, and then the zooplankton content in the entire carbon filter tank 11 can be inferred, and the information is fed back to the control unit in real time. When the measured zooplankton content reaches the set threshold value, the disinfection condition is triggered, and then the disinfection mechanism is controlled by the control unit to start disinfecting the carbon filter tank 11.

[0028] By setting up a monitoring device 21, the zooplankton in the filter water can be monitored in real time, and the disinfection conditions can be automatically triggered and the carbon filter 11 can be disinfected according to the measured zooplankton situation, thereby realizing intelligent control of zooplankton disinfection, reducing pollution of the carbon filter, and ensuring water safety.

[0029] In an exemplary embodiment, the control unit further includes a time module, which is used to obtain the overall monitoring time of the carbon filter 11 and record the time of each disinfection of the filter; when the carbon filter 11 exceeds the set time and has not been disinfected, the control unit controls the disinfection mechanism to start disinfecting the carbon filter 11. Since the carbon filter 11 has not been disinfected for a long time, there may be too many other impurities in the filter, so the filter can be disinfected periodically by setting the time module to further ensure the cleanliness of the filter.

[0030] In an exemplary embodiment, the water treatment system 10 also includes a clean water tank 12 for storing purified water, the disinfection mechanism includes a first connecting device 24, the clean water tank 12 is connected to the carbon filter tank 11 via the first connecting device 24, and the control unit is communicatively connected to the first connecting device 24.

[0031] In some scenarios, the water treatment system 10 includes a carbon filter 11 for filtering water and a clean water tank 12 connected to the treated filter. In this embodiment, the first connecting device 24 is connected between the carbon filter 11 and the clean water tank 12, and the first connecting device 24 is connected by a control unit. The control unit controls the first connecting device 24 to control the input of the clean water tank 12, thereby using the clean water in the clean water tank to clean the carbon filter 11. It can be known that in order to ensure the effectiveness of the cleaning of the carbon filter 11 and prevent secondary pollution during the cleaning process, it is necessary to use a clean water source to clean it. In other scenarios, the first connecting device 24 can also be connected to other disinfection devices or mechanisms equipped with clean water instead of being connected to the clean water of the water treatment system 10 to achieve the disinfection of the carbon filter 11.

[0032] In one implementation of the present embodiment, the carbon filter tank 11 is connected to the clean water tank 12 via a conduit, a liquid pump for pumping water is provided on the conduit, and the control unit is connected to the liquid pump for controlling the switch of the liquid pump, and the pumping control of the clean water tank is realized by controlling the switch of the liquid pump. It is understandable that the first connecting device 24 is not limited to direct connection, but can also be an indirect connection. For example, in addition to the combination of the conduit and the liquid pump, a combination of a water intake device and a transport device can also be used. The clean water of the clean water tank 12 is obtained by the water intake device, and then the transport device is controlled by the control unit to transport the clean water to the filter tank for water flushing and disinfection, etc., as long as the transmission of clean water can be completed.

[0033] In an exemplary embodiment, the disinfecting mechanism further includes a second connecting device 25 and a first disinfecting device 22, the first disinfecting device 22 is connected to the carbon filter 11 via the second connecting device 25, and the control unit is in communication connection with the second connecting device 25. In this embodiment, the disinfecting mechanism includes other devices for disinfecting the filter, which can be connected to the filter via the second connecting device 25 to disinfect it separately, and can also be connected to the first connecting device 24 via the second connecting device 25 to achieve coordinated disinfecting of the carbon filter 11.

[0034] In one implementation of the present embodiment, the first disinfecting device 22 includes an air supply device, the second connecting device 25 includes a second conduit and a gas valve, and the control unit is connected to the gas valve for communication. When the air supply device is connected to the filter tank through the second conduit, the zooplankton in the filter tank can be disinfected by blowing air through the air supply device. The function of the air supply device is to output a certain amount of pressurized gas to achieve air-blasting disinfecting of the filter tank, and examples thereof include but are not limited to blowers, compressors, etc.

[0035] In another implementation of the present embodiment, the first disinfection device 22 includes an air supply device, the second connecting device 25 includes a second conduit and a gas valve, and the control unit is in communication connection with the gas valve. When the air supply device is connected to the first conduit in parallel through the second conduit, that is, the first conduit and the second conduit share an output end, when the control unit simultaneously controls the gas valve and the first liquid pump to open, the air supply device can mix pressurized gas into the clean water in the first conduit to output pressurized clean water with a higher pressure, thereby achieving coordinated disinfection of the carbon filter 11, and the disinfection effect is better than that of separate air flushing disinfection and water flushing disinfection.

[0036] In an exemplary embodiment, the disinfecting mechanism further includes a third connecting device 26 and a second disinfecting device 23, the second disinfecting device 23 is connected to the first connecting device 24 or to the carbon filter 11 via the third connecting device 26, and the control unit is in communication connection with the third connecting device 26. In this embodiment, the disinfecting mechanism includes a second disinfecting device 23 for disinfecting the carbon filter 11, the second disinfecting device 23 is connected to the carbon filter 11 via the third connecting device 26 to disinfect it separately, and can also be connected to the first connecting device 24 via the third connecting device 26 to achieve coordinated disinfecting of the carbon filter 11.

[0037] In one implementation of the present embodiment, the second disinfection device 23 includes a disinfection device, the disinfection device is used to store disinfectant, the third connection device 26 includes a third conduit and a second liquid pump, and the control unit is connected to the second liquid pump. When the disinfection device is directly connected to the carbon filter 11 through the third conduit, the control unit controls the second liquid pump to pump out the disinfectant, and the disinfectant can be directly transported to the carbon filter 11 through the third conduit for disinfection and cleaning. Optionally, the disinfectant uses a sodium hypochlorite solution with a concentration of 10%. In order to meet the disinfection requirements of different scenarios, the type and concentration of the disinfectant can be set differently.

[0038] In one implementation of the present embodiment, the second disinfection device 23 includes a disinfection device, the disinfection device is used to store disinfectant, the third connection device 26 includes a third conduit and a second liquid pump, and the control unit is connected to the second liquid pump in communication. When the disinfection device is connected to the first conduit through the third conduit, that is, when the first conduit and the third conduit share an output end, after the control unit controls the second liquid pump to pump out the disinfectant, the disinfectant can be mixed with clean water through the third conduit to disinfect the carbon filter tank. When different disinfection requirements are met, the concentration of the disinfectant can be adjusted by mixing it into clean water, without the need to configure the concentration of the disinfectant separately, which is more convenient and flexible to use.

[0039] In one implementation of the present embodiment, the second disinfection device 23 includes a disinfection device, the disinfection device is used to store disinfectant, the third connecting device 26 includes a third conduit and a second liquid pump, and the control unit is connected to the second liquid pump. When the disinfection device is connected to the first conduit through the third conduit, that is, the first conduit shares an output end with the second conduit and the third conduit, after the control unit controls the second liquid pump to pump out the disinfectant, the disinfectant, clean water and air blowing can be used through the third conduit to disinfect the carbon filter 11 at the same time, so that the high-pressure liquid containing the disinfectant can be used to disinfect the filter. At the same time, through different control combinations, water flushing disinfection, water flushing disinfection with clean water and air blowing, and water flushing disinfection with disinfectant and water flushing can be achieved. Therefore, different disinfection requirements can be achieved through different control methods of the control unit.

[0040] By setting up multiple disinfection devices and connecting them in parallel through pipelines, different devices can be controlled to achieve coordinated disinfection of each disinfection device, while meeting the needs of personalization and flexibility.

[0041] In some application scenarios, such as Figure 2 As shown, the water treatment system includes an activated carbon filter for filtering water. The carbon filter is usually located at the back end of the water treatment system. The back end of the carbon filter is usually connected to a clear water pool for storing filtered clean water. The biological activated carbon filter process has the functions of ordinary rapid filter and activated carbon adsorption, and has a good effect on removing various zooplankton in the water. However, since the activated carbon filter mainly uses activated carbon particles as fillers, which are conducive to the adhesion and growth of zooplankton, for the post-activated carbon filter, under suitable conditions, the risk of zooplankton leakage in the filter is extremely high. Therefore, the activated carbon filter needs to disinfect the zooplankton breeding in the lower area of ​​the filter bed. The sword water flea online monitoring device is installed on the outlet pipe of the carbon filter, and 25L of water is automatically collected from the carbon filter every hour. The sword water flea changes in the water body are automatically measured through image recognition technology, and the cumulative sword water flea zooplankton amount is automatically calculated, and the disinfecting mechanism is controlled based on the accumulated zooplankton amount to disinfect.

[0042] The disinfection mechanism includes a blower and a disinfection tank containing disinfectant. A connecting pipe is connected between the clean water tank and the carbon filter tank. The connecting pipe has an output end and three input ends. The output end is connected to the carbon filter tank, and the three input ends are respectively connected to the clean water tank, the blower and the disinfection tank. The clean water tank is used for water flushing and disinfection of the carbon filter tank, the blower is used for air flushing and disinfection, and the disinfection tank is used for disinfection and disinfection. Since the pipes of the clean water tank, the blower and the disinfection tank are connected in parallel, the various devices can be combined for disinfection and disinfection, so as to realize air-water flushing and disinfection, disinfection and disinfection by water flushing, etc. In order to realize the control of the disinfection mechanism, corresponding devices are provided at each input end of the connecting pipe for controlling the input of each disinfection device, wherein a liquid pump is provided on the connecting pipe between the clean water tank and the carbon filter tank, another liquid pump is provided on the connecting pipe connected to the disinfection tank, and a valve is provided on the connecting pipe of the blower. Each liquid pump and valve can be controlled by a control unit.

[0043] According to the different cleaning intensity and cleaning effect of zooplankton in the filter bed according to the disinfection level of the carbon filter, and considering that zooplankton should not block the filter and cause the filter to overflow, the bioaccumulation measured by the sword water flea online monitoring device is graded. For example, the first level is 50 zooplankton per 100 liters of water, and the second level is 80 zooplankton per 100 liters of water. By grading the zooplankton content, the disinfection needs in different situations can be met according to different grading conditions and combined with corresponding control methods. A specific control method such as Figure 3 As shown, when the filter tank runs for a certain period of time and reaches the preset disinfection cycle but the accumulated biomass of the carbon filter tank has not reached the first-level setting value, the liquid pump of the clean water tank and the valve of the blower are opened to achieve air flushing disinfection, air-water flushing disinfection, and water flushing disinfection of the carbon filter tank. When the operation time of the carbon filter tank reaches the preset cycle or the accumulated amount of biomass in the filter tank effluent reaches the first-level setting value, the liquid pump of the clean water tank, the blower valve and the liquid pump of the disinfection tank are opened to disinfect and disinfect the carbon filter tank, and air flushing disinfection, air-water flushing disinfection and disinfection with the addition of disinfectant to assist water flushing. When the accumulated amount of biomass in the filter tank effluent suddenly increases to reach the second-level setting value, the liquid pump of the clean water tank and the liquid pump of the disinfection tank are opened, and the disinfectant solution is started for emergency disinfection. After completing the above disinfection, the accumulated amount of zooplankton in the carbon filter tank is recalculated. When the above disinfectant assists in water flushing disinfection of the carbon filter tank, the disinfectant is a 10% concentration of sodium hypochlorite solution. The disinfection time is generally 600s. When the above disinfectant solution is used to soak the pool and disinfect the filter, the disinfectant is a 10% concentration of sodium hypochlorite solution, and the soaking time is 3 hours.

[0044] An embodiment of the present application also provides a water treatment system 10, and the zooplankton disinfecting equipment 20 in the above embodiments applies the water treatment system 10, and the water treatment system 10 includes a clean water tank 12 and a carbon filter tank 11; in addition, the water treatment system can also include at least a sand filter tank and an ozone contact tank, and the sand filter tank, the ozone contact tank, the carbon filter tank and the clean water tank are connected in sequence.

[0045] Compared with the related art, the present application monitors the zooplankton in the filter pool water in real time by setting up a monitoring device, and can automatically trigger the disinfecting conditions according to the measured zooplankton situation and control the corresponding disinfecting device to disinfect the target pool, thus realizing the intelligent disinfecting of zooplankton and timely solving various zooplankton excess problems, thereby improving the cleanliness of the pool and ensuring water safety. In addition, by setting up multiple disinfecting devices to disinfect the pool, the disinfecting needs in various scenarios can be met, and the disinfecting devices can be connected in parallel to achieve the coordinated disinfecting of multiple disinfecting devices, which can achieve better disinfecting effects and have better flexibility.
