[0026] like Figure 1 As shown, the embodiment of the present invention first provides a water supply filtration system suitable for a pig farm, which is arranged in a pig farm. A water source is provided in the pig farm. The raw water in the water source can be tap water or well water. The water supply filtration system suitable for a pig farm filters and purifies the raw water in the water source. The filtered and purified water flows to various water use points in the pig farm. The water supply filtration system suitable for a pig farm includes a first coarse filtration device 1, an automatic chlorine preparation dosing device, an ultraviolet disinfection device 3 and a digital control center storing a control program. The first coarse filtration device 1, the automatic chlorine preparation dosing device and the ultraviolet disinfection device 3 are sequentially arranged along the flow direction of the raw water to be filtered and purified in the water supply filtration system suitable for a pig farm and are connected by pipelines. The automatic chlorine preparation dosing device and the ultraviolet disinfection device 3 are electrically connected to the digital control center respectively;

[0027] The raw water flows through the first coarse filtration equipment 1, the automatic chlorine preparation dosing equipment and the ultraviolet disinfection device 3, and is filtered, disinfected for the first time and disinfected for the second time in sequence to achieve three-screen process disinfection; the water supply filtration system suitable for pig farms is connected to various water use points in the pig farms through pipes, and the various water use points in the pig farms include pig farm production water and human drinking water.

[0028] The first coarse filtration device 1 includes a quartz sand filter 11 and a bag filter 12. The quartz sand filter 11 and the bag filter 12 are arranged in sequence along the flow direction of raw water inside the first coarse filtration device 1. The particle diameter that can pass through the quartz sand filter 11 is less than 100um, and the particle diameter that can pass through the bag filter 12 is less than 50um. The double-layer filtration method can more effectively capture impurities of different sizes and types, improve the filtration accuracy, and even if one layer of filtration is locally blocked or the performance is degraded, the other layer can still play a role, thereby improving the stability of filtration; during the long-term use of the quartz sand filter 11 and the bag filter 12, the filter screen may be blocked due to sand or other impurities in the raw water, thereby affecting the filtration effect of the quartz sand filter 11 and the bag filter 12, so the quartz sand filter 11 and the bag filter 12 should be backwashed once every 30 minutes.

[0029] like Figure 1-4 As shown, the chlorine preparation automatic dosing equipment includes a water tower 2 and a chlorine preparation equipment room 4. The interior of the chlorine preparation equipment room 4 is provided with a chlorine preparation dosing system 23. The outlet pipe of the water tower 2 is installed with a residual chlorine online monitor 22 and a water valve 21. The water valve 21 and the residual chlorine online monitor 22 are both electrically connected to the digital control center. The opening and closing of the water valve 21 are controlled by the digital control center. The residual chlorine online monitor 22 transmits the collected data to the digital control center. The residual chlorine online monitor 22 monitors the residual chlorine value of the water in the water outlet pipe of the water tower 2 after one disinfection. When the outlet pipe of the water tower 2 is When the residual chlorine value of the water after one disinfection in the water pipe is ≥0.3 (mg / L) and ≤2 (mg / L), the digital control center controls the water valve 21 to open, so that the water after one disinfection passes through the water tower 2 and enters the ultraviolet disinfection device 3; the output end of the chlorine preparation dosing system 23 is connected to the water inlet end of the water tower 2 through a pipe. The chlorine preparation dosing system 23 uses a chlorine preparation that can produce "hypochlorous acid" when dissolved in water for disinfection. The chlorine preparations that can be used include sodium hypochlorite and chlorine dioxide. Considering that sodium hypochlorite has better stability, sodium hypochlorite is preferably used.

[0030] As a preferred embodiment of the present invention, Figure 4As shown, the chlorine preparation dosing system 23 includes a metering pump 231, and an atomizing barrel 232 is provided at the drug outlet end of the metering pump 231. The drug outlet end of the atomizing barrel 232 is connected to the water inlet pipe of the water tower 2. The number of atomizing barrels 232 can be multiple, and multiple atomizing barrels 232 are set in series. The speed of atomization disinfection can be improved by multi-stage atomizing barrels 232; the metering pump 231 is electrically connected to the digital control center, and the metering pump 231 receives a signal from the digital control center to add sodium hypochlorite solution to the atomizing barrel 232. The digital control center performs PID adaptive control according to the residual chlorine value and the fluctuation range and fluctuation frequency of the active oxygen parameter in the atomizing barrel 232 and the water tower 2, and adjusts the amount and addition speed of the sodium hypochlorite solution added by the metering pump 231.

The operation mode of the cleaning device 36 is 4 hours as a cycle, and two rounds of cleaning are performed in each cycle, thereby reducing the dirt on the surface of the quartz sleeve of the UVC ultraviolet lamp 37 and avoiding the phenomenon of low UV transmittance caused by the sleeve structure.

[0032] An electromagnetic flowmeter 32 is installed at the water inlet of the housing 31. The electromagnetic flowmeter 32 is used to measure the flow of liquid entering the ultraviolet disinfection device 3, so that the digital control center can better control the disinfection process of the water after one disinfection and monitor the operating status of the ultraviolet disinfection device 3, thereby ensuring stable and safe cleaning.

[0033] A temperature sensor 33, a UV light intensity monitor 34, and a fluid UVT measurement sensor 35 are installed on the inner top wall of the housing 31; the temperature sensor 33 constantly monitors the temperature data in the ultraviolet disinfection device 3. When the temperature of the ultraviolet disinfection device 3 is not between 130°C and 140°C, it promptly sends an alarm to the digital control center and constantly monitors the temperature data and uploads it to the digital control center;

[0034] The fluid UVT measurement sensor 35 measures the UVC ultraviolet transmittance in the ultraviolet disinfection device 3. When the UVC ultraviolet transmittance is ≤90%, the digital control center controls the cleaning device 36 to clean the quartz sleeve of the UVC ultraviolet lamp 37 in time.

[0035] The UV light intensity monitor 34 reads the current irradiation intensity of the UVC ultraviolet lamp 37, which is used as the calculation value for the current disinfection dose of the ultraviolet disinfection device 3. It mainly reads flow data, cleaning control monitoring, and UV reaction chamber temperature. The data is read to facilitate the digital control center to operate the corresponding equipment;

[0036] The digital control center uses the UV lamp irradiation intensity and water flow value measured by the above device to configure the appropriate UVC ultraviolet disinfection dose in conjunction with the UVC ultraviolet lamp 37, so as to disinfect the water after one disinfection again. During the operation of the entire equipment, the actual output dose should be able to be dynamically and constantly output against the target metering, so that the actual dose output is not lower than the target set dose, preventing the waste of disinfectant due to excessive output metering, and also avoiding the phenomenon of poor disinfection effect caused by too little output disinfection dose.

[0037] In one embodiment, the ultraviolet disinfection device 3 is also connected to a UV lamp operation data monitoring device, which monitors the operating parameters of the UVC ultraviolet lamp 37, including the real-time output power of the lamp tube, the real-time current of the lamp tube, the real-time tube pressure of the lamp tube, the running time of the lamp tube, the cumulative number of starts and stops, the number of starts and stops on the day, etc. (the UV lamp operation data monitoring device has multiple embodiments in the prior art, and its specific structure is not the technical problem to be solved by the present invention) to ensure the normal operation of the UVC ultraviolet lamp 37.

The water pump in the water pump room 5 allows the water after the first disinfection to enter the ultraviolet disinfection device 3 for disinfection, and the water after the second disinfection is supplied to each water use point in the pig farm through the water pump.

[0039] like Figure 3 As shown, as a preferred embodiment of the present invention, a second water pump room water pipe 52 is further provided in the water pump room 5, and a water pump is also provided on the second water pump room water pipe 52.

A raw water barrel 41 is also provided in the chlorine preparation equipment room 4. The water inlet end of the raw water barrel 41 is connected to the water outlet end of the second water pump room water pipe 52. The raw water barrel 41 temporarily stores the raw water after the first filtration flowing from the water tower 2. The raw water after the first filtration is temporarily stored through the raw water barrel 41.

[0040] The water outlet of the raw water barrel 41 is connected to a second coarse filtration device 6, and the water outlet of the second coarse filtration device 6 is connected to a clean water barrel 42. The water outlet of the clean water barrel 42 is connected to the water inlet of the water use point in the pig farm and / or the water inlet pipe of the automatic dosing of chlorine preparations; the second coarse filtration device 6 includes a quartz sand filter and a bag filter, and the specifications of the quartz sand filter and the bag filter are the same as or different from those of the quartz sand filter and the bag filter in the first coarse filtration device respectively; the second coarse filtration device 6 set in the chlorine preparation equipment room 4 is used to perform a second coarse filtration on the raw water after the first filtration. The raw water after the second filtration is transferred through the clean water barrel 42 and then enters the water tower 2 for reaction; the raw water after the second filtration in the clean water barrel 42 can also directly enter the pig house, so that the staff can use the raw water after the second filtration to deodorize the pig house; the raw water after the second filtration in the clean water barrel 42 can also be used to make chlorine preparations, thereby avoiding the phenomenon of idling of the metering pump 231.
