[0003] The harsh marine environment and the high electricity demands of wastewater treatment facilities severely restrict the development of marine wastewater treatment technology. Traditional treatment methods are inefficient, involve large-scale engineering projects, and are costly. Furthermore, the development of marine wastewater treatment also impacts the quality of life for people living at sea.

[0004] Therefore, designing a marine sewage treatment device that can efficiently treat sewage and simultaneously achieve its recycling is an urgent problem to be solved. Utility Model Content

[0005] The purpose of this invention is to provide a floating island-style self-purifying toilet. The innovation lies in utilizing anaerobic and aerobic biochemical reactions, along with filtration processes targeting different substances, to achieve highly efficient purification of domestic sewage, converting it into reusable drinking water. This improves sewage treatment efficiency, overcomes the technical challenges of marine sewage treatment, and achieves environmental protection. Furthermore, it enables the recycling of sewage, providing convenience for people living at sea, especially in terms of drinking water, and effectively improving the quality of life for those at sea.

[0006] To achieve the aforementioned objectives, the technical solution of this utility model is as follows: A floating island-style self-purifying toilet includes an equipment platform, an anaerobic biochemical chamber, an aerobic biochemical chamber, a control room, an MBR biofilm reactor, a primary product water tank, a secondary product water tank, an MBR product water pump, a nanofiltration booster pump, an ultrasonic automatic cleaning microfilter, a nanofiltration membrane separator, an ultraviolet sterilizer, an automatic controller, a micro-power circulation pump, and water-using equipment. The anaerobic and aerobic biochemical chambers are located on one side of the equipment platform and are connected to each other. A toilet area is formed on the side of the equipment platform opposite to the anaerobic biochemical chamber. The control room, primary product water tank, secondary product water tank, and water-using equipment are all located in the toilet area, and the control room, primary product water tank, and secondary product water tank are located on the same side of the toilet area. The control room is sandwiched between the primary product water tank and the secondary product water tank. Between the primary and secondary product water tanks; the MBR biofilm reactor is located in the aerobic biochemical chamber, and the MBR biofilm reactor is connected to the ultrasonic automatic cleaning microfilter via the MBR product water pump; the ultrasonic automatic cleaning microfilter is connected to the primary product water tank; the primary product water tank is connected to the nanofiltration membrane separator via the nanofiltration booster pump; the nanofiltration membrane reactor is connected to the ultraviolet sterilizer; the ultraviolet sterilizer is connected to the secondary product water tank; the primary and secondary product water tanks are respectively connected to the water-using equipment; the ultrasonic automatic cleaning microfilter and the nanofiltration membrane separator are respectively connected to the anaerobic biochemical chamber; the automatic controller is located in the control room, and the automatic controller is connected to the nanofiltration booster pump, the ultrasonic automatic cleaning microfilter, the nanofiltration membrane separator, the ultraviolet sterilizer, and the micro-power circulation pump.

[0007] The aforementioned process utilizes anaerobic and aerobic biochemical reactions, along with filtration techniques targeting different substances, to achieve highly efficient purification of domestic sewage, transforming it into reusable drinking water. This improves sewage treatment efficiency, overcomes the technical challenges of marine sewage treatment, and achieves environmental protection goals. Furthermore, it enables the recycling of sewage, providing convenience for people living at sea, particularly in terms of drinking water, and effectively improving the quality of life for those at sea.

[0008] Preferably, the water-using equipment includes a toilet, a handwashing water pipe, a shower, and a water heater; the toilet is connected to an ultrasonic automatic cleaning microfilter; the handwashing water pipe and the water heater are both connected to a secondary water production tank; and the shower is connected to the water heater.

[0009] In the above process, the purified water can be used for various purposes of domestic water use, thus fully realizing the recycling of domestic water.

[0010] As a preferred option, the anaerobic organisms in the anaerobic biochemistry chamber are cultured using BioBV special anaerobic microbial strains produced in South Korea; and the aerobic organisms in the aerobic biochemistry chamber are cultured using BioBV special aerobic microbial strains produced in South Korea.

[0011] In the above process, the anaerobic biological treatment chamber uses a special anaerobic microbial strain from BioBV (Korea) to cultivate an anaerobic microbial activated sludge bed, which decomposes organic matter in wastewater to improve the treatment effect of aerobic biological treatment. This sludge bed is characterized by good biodegradability, good stability, and strong decomposition capacity. The aerobic biological treatment chamber uses a special aerobic microbial strain from BioBV (Korea) to cultivate an aerobic microbial activated sludge bed, which removes organic matter from wastewater and consumes nitrogen and phosphorus sources in the water body to improve the overall treatment effect of aerobic biological treatment. This sludge bed is characterized by good biodegradability, good stability, and strong removal capacity; it also has sludge digestion function, which can greatly reduce sludge production.

[0013] In the above process, the use of fiber bundle nanoporous aeration in the aerobic biochemical chamber can increase the density of aerated dissolved water and improve oxygen utilization efficiency; it can also reduce the amount of aeration supplied, thereby reducing energy consumption.

[0014] Preferably, it also includes pontoons and floating boxes; the pontoons are on the same side of the equipment platform as the anaerobic biochemical chamber; the pontoons are spaced apart around the edge of the equipment platform; and the floating boxes are embedded in the equipment platform.

[0015] In the above process, the floating box mainly serves to enhance the overall equipment platform's impact resistance and buoyancy capacity.

[0023] The technical solutions in the embodiments of this utility model will now be clearly and completely described with reference to the accompanying drawings.

[0024] Please see Figures 1-3This embodiment provides a floating island type self-cleaning toilet. This floating island-style self-purifying toilet includes an equipment platform 01, an anaerobic biochemical chamber 014, an aerobic biochemical chamber 013, a control room 011, an MBR biofilm reactor 012, a primary product water tank 07, a secondary product water tank, an MBR product water pump 06, a nanofiltration booster pump, an ultrasonic automatic cleaning microfilter 05, a nanofiltration membrane separator 04, an ultraviolet sterilizer 09, an automatic controller, a micro-power circulation pump, and water-using equipment. The anaerobic biochemical chamber 014 and the aerobic biochemical chamber 013 are located on one side of the equipment platform 01 and are connected to each other. A toilet area is formed on the side of the equipment platform 01 opposite to the anaerobic biochemical chamber 014. The control room 011, the primary product water tank 07, the secondary product water tank, and the water-using equipment are all located within the toilet area, and the control room 011, the primary product water tank 07, and the secondary product water tank are located on the same side of the toilet area. The control room 011 is sandwiched between... Between the primary product water tank 07 and the secondary product water tank; the MBR biofilm reactor 012 is located in the aerobic biochemical chamber 013, and the MBR biofilm reactor 012 is connected to the ultrasonic automatic cleaning microfilter 05 through the MBR product water pump 06; the ultrasonic automatic cleaning microfilter 05 is connected to the primary product water tank 07; the primary product water tank 07 is connected to the nanofiltration membrane separator 04 through the nanofiltration booster pump; the nanofiltration membrane reactor is connected to the ultraviolet sterilizer 09; the ultraviolet sterilizer 09 is connected to the secondary product water tank; the primary product water tank 07 and the secondary product water tank are respectively connected to the water-using equipment; the ultrasonic automatic cleaning microfilter 05 and the nanofiltration membrane separator 04 are respectively connected to the anaerobic biochemical chamber 014; the automatic controller is located in the control room 011, and the automatic controller is connected to the nanofiltration booster pump, the ultrasonic automatic cleaning microfilter 05, the nanofiltration membrane separator 04, the ultraviolet sterilizer 09, and the micro-power circulation pump.

[0025] Floating island-style self-purifying toilets utilize anaerobic and aerobic biochemical reactions, along with filtration processes targeting different substances, to achieve highly efficient purification of domestic sewage, converting it into reusable drinking water. This not only improves sewage treatment efficiency and overcomes the technical challenges of marine sewage treatment, achieving environmental protection goals, but also enables the recycling of sewage, providing convenience for people living at sea, especially in terms of drinking water usage, and effectively improving the quality of life for those at sea.

[0026] The water treated by the floating island self-purifying toilet can be used for various domestic water uses, fully realizing the recycling of domestic water. In this embodiment, the water-using equipment includes a toilet, a handwashing water pipe, a shower 04, and a water heater 03; the toilet is connected to an ultrasonic automatic cleaning microfilter 05; the handwashing water pipe and the water heater 03 are both connected to a secondary water production tank; the shower 04 is connected to the water heater 03.

[0027] Anaerobic biological treatment chamber 014 and aerobic biological treatment chamber 013 respectively conduct anaerobic and aerobic biological reactions on domestic sewage. It should be noted that, in this embodiment, the anaerobic organisms in anaerobic biological treatment chamber 014 are cultured using a special anaerobic microbial strain of BioBV from South Korea; the aerobic organisms in aerobic biological treatment chamber 013 are cultured using a special aerobic microbial strain of BioBV from South Korea.

[0028] Thus, in anaerobic biological treatment chamber 014, an anaerobic microbial activated sludge bed cultivated with special anaerobic microbial strains from South Korea, BioBV, decomposes organic matter in wastewater to improve the treatment effect of aerobic biological treatment. It features good biodegradability, good stability, and strong decomposition capacity. In aerobic biological treatment chamber 013, an aerobic microbial activated sludge bed cultivated with special aerobic microbial strains from South Korea, BioBV, removes organic matter from wastewater and consumes nitrogen and phosphorus sources in the water body to improve the overall treatment effect of aerobic biological treatment. It features good biodegradability, good stability, and strong removal capacity; it also has sludge digestion function, which can greatly reduce sludge production.

[0029] Understandably, in order to increase the density of the aerated dissolved air water and improve oxygen utilization efficiency, the aeration supply should be reduced to decrease energy consumption. In this embodiment, a fiber bundle aerator 015 and an aeration fan are provided; the fiber bundle aerator 015 is installed in the aerobic biochemical chamber 013; the aeration fan is installed in the toilet area; the fiber bundle aerator 015 is connected to the aeration fan; and an automatic controller is connected to the aeration fan.

[0030] Since the floating island self-purifying toilet is located at sea, considering the marine environment, this embodiment includes pontoons 02 and floating boxes. The pontoons 02 are located on the same side of the equipment platform 01 as the anaerobic biological treatment chamber 014. The pontoons 02 are spaced apart around the edge of the equipment platform 01. The floating boxes are embedded in the equipment platform 01. The floating boxes primarily enhance the overall impact resistance and buoyancy capacity of the equipment platform 01. The pontoons 02 primarily function to automatically balance and adjust the system during wave impacts and after drainage from the product water process section, thereby ensuring the balance of the entire treatment system and enabling it to operate normally for extended periods.

[0031] Of course, the number and location distribution of the floating boxes and pontoons 02 can be determined based on the actual environmental conditions and design requirements. As long as the design can enhance the overall equipment platform 01's impact resistance and buoyancy capacity, ensure the balance of the entire processing system, and enable it to operate normally for a long period of time, it is acceptable.

[0032] Because processes such as biochemical reactions generate waste gases, these gases have a pungent odor and pollute the air, causing environmental impact. In this embodiment, a deodorizing exhaust device 08 is installed, which is connected to both the aerobic biochemical chamber 013 and the anaerobic biochemical chamber 014. The deodorizing exhaust device 08 primarily decomposes and removes odors from the waste gases during discharge, thus solving the problem of odor pollution and protecting the air environment. It should be noted that the deodorizing exhaust device 08 uses abasta plant essential oil gas as a deodorizing agent. This gas can fully react with the waste gases, decomposing them and preventing the waste gases from affecting the environment.

[0033] Understandably, due to the harsh marine environment, effective rainproofing, sun protection, cooling, UV protection, and wave resistance are required for the equipment platform 01 and its equipment facilities. In this embodiment, a protective cover is provided; the protective cover is installed on the equipment platform 01.

[0034] This embodiment provides the following specific implementation method: Domestic sewage enters the anaerobic biological treatment chamber 014 through the manhole, where anaerobic biological reactions occur, decomposing the organic matter in the sewage. After passing through the anaerobic biological treatment chamber 014, the sewage enters the aerobic biological treatment chamber 013 for aerobic biological reactions, further decomposing the organic matter. After the aerobic biological reactions, the sewage is filtered through the MBR biofilm reactor 012. The sewage filtered through the MBR biofilm reactor 012 is then pumped by the MBR permeate pump 06 into the ultrasonic automatic cleaning microfilter 05 for further filtration. After filtration, the filtered water is stored in the primary permeate tank 07 for toilet flushing.

[0035] The MBR permeate pump 06 is designed using a 24V micro-power diaphragm pump with an operating power of 30W, reducing power consumption while achieving the function of micro-power. The ultrasonic automatic cleaning microfilter 05 uses a sintered titanium filter element and is equipped with an online continuous ultrasonic cleaning function. This design eliminates the need for backwashing and a backwash water source, ensuring a clog-free operation, long-term high efficiency, and improved treatment and purification effects.

[0036] In addition, the wastewater in the primary product water tank 07 is connected to the nanofiltration membrane separator 04 via a nanofiltration booster pump, allowing the wastewater to be filtered in the nanofiltration membrane separator 04. Here, the nanofiltration membrane separator 04 mainly removes pollutants larger than nanometers from the water, as well as E. coli, calcium and magnesium ions, and other salts, thereby ensuring the quality of the treated water purification and the safety of the recycled water. Only water that has passed through the nanofiltration membrane separator 04 can be used as a source of domestic water. For example, it can be heated by the water heater 03 and then used as bath water through the shower 04, or it can be used for washing hands and other purposes after passing through the handwashing pipe. It can be recycled to obtain fresh water, thus solving most of the fresh water shortage problem.

[0037] Of course, before being used as a source of drinking water, the water filtered by the nanofiltration membrane separator 04 needs to be disinfected by a UV sterilizer. Here, the UV sterilizer primarily disinfects and sterilizes the nanofiltration product water to ensure the safety of the recycled water. This UV sterilizer is powered by 24V and consumes 15W, making it a low-power device, and is made of 304 stainless steel.

[0038] The recycled water after passing through the UV sterilizer 09 will be stored in the secondary product water tank as storage water for the recycled water.

[0039] Throughout the process, all power systems are connected to an automatic controller, which provides unified control and management to achieve efficient purification and circulation. This automatic controller can be a PLC industrial controller, or other types of control devices and equipment.

[0040] In addition, in order to achieve efficient control by the automatic controller, monitoring and data acquisition instruments and facilities will be set up at key process equipment or data acquisition points to provide accurate data for the automatic controller to make efficient control responses. These instruments and facilities include online COD detectors, turbidity detectors, conductivity detectors, and pH meters.

[0041] In summary, the floating island self-purifying toilet provided in this embodiment utilizes anaerobic and aerobic biochemical reactions, along with filtration processes targeting different substances, to achieve highly efficient purification of domestic sewage, converting it into reusable drinking water. On one hand, this improves the treatment effect of domestic sewage, overcoming the technical challenges of marine sewage treatment and achieving environmental protection goals. On the other hand, it enables the recycling of domestic sewage, providing convenience for people living at sea, especially in terms of drinking water usage, and effectively improving the quality of life for people living at sea.

[0042] The described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
