Description

Technical Field

[0001] The present invention relates to the field of advanced emission reduction technology for dual-fuel marine engines, and in particular to a biodegradable sewage treatment container and method for iCER water treatment. Background Art

[0002] Ship wastewater discharge requires that indicators such as biochemical oxygen demand, suspended solids, and E. coli must meet specified limits. Traditional ship wastewater treatment methods primarily include physical sedimentation, chemical disinfection, and biodegradation. Biodegradation technology, with its advantages of high treatment effectiveness and low operating costs, has been widely used in the shipbuilding industry.

[0003] However, existing marine biodegradation systems generally suffer from unstable treatment efficiency and inadequate control of harmful gas emissions. This is especially true when used in conjunction with new shipboard iCER (internal exhaust gas recirculation) systems, as traditional wastewater treatment equipment struggles to meet the requirements of integration and intelligentization. Therefore, technological improvements and upgrades are needed.

[0004] Specifically, conventional marine sewage storage containers are typically sealed, box-like structures. Even if they incorporate biodegradation capabilities, they only serve a simple purpose of storage and initial degradation. During storage, domestic sewage, due to microbial activity, produces large amounts of harmful gases, which can harm crew health and the marine environment. Furthermore, these devices have low biodegradation efficiency, making it difficult to fully decompose organic matter and other pollutants in the sewage. Direct discharge still seriously pollutes marine ecosystems. Furthermore, currently available marine biodegradation devices primarily utilize fixed biofilm processes or activated sludge processes, typically treating sewage through multi-stage filtration and aeration biodegradation. However, these bio-filler layers have a simple structure and limited microbial attachment area, resulting in decreased treatment efficiency over time. Furthermore, existing devices generally lack intelligent control systems, preventing them from automatically adjusting operating parameters based on changes in sewage load. Consequently, over-aeration or insufficient oxygen supply often occur during actual ship operation. These issues are particularly prominent when used in conjunction with ship-based iCER systems, which consume significant energy and are complex, requiring the sewage treatment equipment to possess greater adaptability and stability. Summary of the Invention

[0005] In view of this, the present invention provides a biodegradable sewage treatment container and method for iCER water treatment to solve the problems of unstable treatment efficiency and insufficient control of harmful gas emissions in the existing marine sewage storage containers.

[0006] In a first aspect, the present invention provides a biodegradable sewage treatment container for iCER water treatment, comprising:

[0007] chassis;

[0008] A sedimentation and filtration assembly is fixedly connected to the top of the base frame;

[0009] A biodegradation mechanism is fixedly connected to the top of the base frame, and the biodegradation mechanism is in communication with the sedimentation and filtration assembly;

[0010] a gas processing device connected to the biodegradation mechanism;

[0011] The biodegradation mechanism includes a shell having a bottom fixedly connected to the base frame, an aeration mechanism provided on the shell and communicating with the interior of the shell, a back plate fixedly connected to the interior of the shell, a mounting frame fixedly connected to the back plate, and a multi-layer biological filler layer fixedly connected to the mounting frame;

[0012] The gas processing equipment includes an exhaust pipe with one end connected to the shell, a cylinder connected to the other end of the exhaust pipe, a gas filter assembly fixedly connected to the inner cavity of the cylinder, an exhaust hood connected to the gas outlet end of the cylinder, and a fan fixedly connected to the exhaust hood.

[0013] The multi-layer biological filler layer combined with the air introduced by the aeration mechanism greatly increases the contact area between microorganisms and sewage, significantly improving the degradation efficiency of pollutants and making it easier for treated sewage to meet discharge or reuse standards; the gas treatment equipment can promptly collect and purify harmful gases through the coordination of exhaust pipes, cylinders, gas filter components, exhaust hoods and fans, avoiding their accumulation in the outer shell and causing pressure increases, ensuring the safe operation of the container at normal pressure, while preventing harmful gases from polluting the environment, ensuring the stable operation of the iCER water treatment system and the safety of the marine environment.

[0014] In an optional embodiment, the gas filter assembly includes:

[0015] A fixing frame, fixedly connected to the inner cavity of the cylinder;

[0016] A connecting column, fixedly connected to the fixing frame on a side close to the air outlet end of the cylinder;

[0017] The filler adsorption layer, the activated carbon filter layer and the catalytic oxidation material layer are sequentially sleeved on the surface of the connecting column along a side of the connecting column close to the gas outlet end of the cylinder.

[0018] The gas filtration component purifies harmful gases layer by layer through the sequential action of the filler adsorption layer, activated carbon filter layer, and catalytic oxidation material layer, comprehensively removing all types of harmful substances and odors in the gas. The purified gas can be discharged through the exhaust hood under the action of the fan, effectively avoiding the pollution to the environment caused by the direct emission of harmful gases. At the same time, it prevents the accumulation of harmful gases in the container and causes pressure increase, ensuring the safe operation of the container at normal pressure and providing strong support for the stable operation of the iCER water treatment system.

[0019] In an optional embodiment, the aeration mechanism includes an air pump fixedly connected to the outer shell, a delivery pipe connected to the air outlet end of the air pump, an air inlet pipe connected to the air inlet end of the air pump, and a diverter pipe connected to the air outlet end of the delivery pipe, and the air outlet end of the diverter pipe passes through the outer shell and extends to its inner cavity.

[0020] The air pump draws in air through the intake pipe. After being processed by the air pump, the air enters the delivery pipe, from which it is transported to the diversion pipe. The outlet end of the diversion pipe extends into the inner cavity of the shell, directing the air into the shell. This aeration mechanism provides sufficient air around the biological filler layer within the shell. The air forms bubbles within the shell, fully contacting the sewage flowing through the multiple layers of biological filler. This provides a suitable oxygen environment for the microorganisms growing and multiplying on the biological filler layers, meeting the oxygen demand of the microorganisms to degrade pollutants in the sewage. This in turn enhances the activity and metabolic capacity of the microorganisms, improves the degradation efficiency of pollutants such as organic matter in the sewage, ensures the efficient biodegradation process, and helps the treated sewage more easily meet discharge or reuse standards.

[0021] In an optional embodiment, the sedimentation filtration component comprises:

[0022] a tank body, the top of which is provided with a water inlet pipe;

[0023] A driving member is arranged outside the tank body;

[0024] A rotating shaft, one end of which is fixedly connected to the output end of the driving member, and the other end of which passes through the side wall of the tank body and extends into the interior of the tank body;

[0025] A cleaning rack is located inside the tank and fixedly connected to the rotating shaft;

[0026] A filter mechanism is fixedly connected to the inner cavity of the tank, and the cleaning frame is in contact with the surface of the filter mechanism;

[0027] A connecting pipe, the inlet end of which is connected to the tank body;

[0028] A delivery pump is connected to the outlet end of the connecting pipe and the shell.

[0029] The water inlet pipe facilitates the smooth flow of sewage into the tank body, and the filtering mechanism can effectively intercept and filter various impurities in the sewage, reducing the processing burden of the subsequent biodegradation mechanism; the cleaning rack continuously cleans the filtering mechanism driven by the driving parts and the rotating shaft, which can prevent impurities from accumulating and clogging the filtering mechanism, maintain its filtering performance, and ensure that the filtration process is stable and efficient; the delivery pump stably delivers the filtered sewage to the outer shell through the connecting pipe, providing a suitable treatment object for the biodegradation link, thereby improving the treatment efficiency and effect of the entire sewage treatment container, and helping sewage to more easily meet the discharge or reuse standards.

[0030] In an optional embodiment, the filtering mechanism includes:

[0031] A fixing frame, fixedly connected to the tank body;

[0032] a coarse filter, fixedly connected to the fixed frame;

[0033] a fine filter, located downstream of the coarse filter and fixedly connected to the inner cavity of the tank;

[0034] a fiber filter, located downstream of the fine filter and fixedly connected to the inner cavity of the tank;

[0035] Wherein, the cleaning frame contacts the surface of the coarse filter.

[0036] The coarse filter, fine filter and fiber filter form a three-stage progressive filtration system, which can remove impurities of different particle sizes in the sewage layer by layer, greatly reduce the impurity content in the sewage, reduce the processing pressure for the subsequent biodegradation mechanism, and improve the overall sewage treatment efficiency; the cleaning rack is in contact with the coarse filter to clean it, which can prevent the coarse filter from being blocked by intercepted impurities, maintain its filtration transparency, ensure the stability of the filtration process, eliminate the need for frequent manual cleaning, reduce maintenance costs, and allow the filtered sewage to enter the biodegradation link in a more suitable state, helping the treated sewage to meet the standards more easily.

[0037] In an optional embodiment, a support base is fixedly connected to the bottom of the cylinder, and the bottom of the support base is fixedly connected to the outer shell.

[0038] In an optional embodiment, one side of the bottom of the shell is connected to a drain pipe with a valve.

[0039] In an optional embodiment, a heater and a liquid level sensor are fixedly connected to the top of the housing.

[0040] In an optional embodiment, a control panel is fixedly connected to the surface of the shell, and an adjustment knob is provided on the surface of the control panel, and is electrically connected to the liquid level sensor and the air pump.

[0041] The liquid level sensor transmits real-time monitoring data on the sewage level inside the housing to a control panel electrically connected to it. The control panel automatically adjusts the operating parameters of the air pump, which is also electrically connected to it, based on the liquid level information. At the same time, the operator can manually adjust the equipment's operating parameters using the adjustment knob on the surface of the control panel. The effect is that the control panel receives data from the liquid level sensor and automatically adjusts the air pump, realizing intelligent equipment operation. When the liquid level is low, the air pump aeration volume is reduced or aeration is suspended to save energy. When the liquid level rises, the aeration volume is increased to meet the needs of microbial degradation. The adjustment knob allows operators to manually intervene according to the actual sewage conditions and treatment needs, ensuring that the equipment's operating parameters are adapted to different sewage treatment scenarios, improving the equipment's flexibility and controllability, ensuring the efficient and stable biodegradation process, and contributing to better sewage treatment results.

[0042] In a second aspect, the present invention further provides a sewage treatment method based on the biodegradable sewage treatment container applied to iCER water treatment, comprising the following steps:

[0043] After the sewage enters the tank, it is filtered by the sedimentation and filtration assembly, and then enters the shell;

[0044] The sewage flows through the gaps between the multi-layer biological filler layers, and at the same time, air is injected into the multi-layer biological filler layers through the aeration mechanism to provide oxygen for microorganisms to degrade pollutants;

[0045] The gas generated by the decomposition enters the cylinder through the exhaust pipe, is filtered by the gas filter assembly, and is finally discharged by the fan. BRIEF DESCRIPTION OF THE DRAWINGS

[0065] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0066] Ship wastewater discharge requires that indicators such as biochemical oxygen demand, suspended solids, and E. coli must meet specified limits. Traditional ship wastewater treatment methods primarily include physical sedimentation, chemical disinfection, and biodegradation. Biodegradation technology, with its advantages of high treatment effectiveness and low operating costs, has been widely used in the shipbuilding industry.

[0067] However, existing marine biodegradation systems generally suffer from unstable treatment efficiency and inadequate control of harmful gas emissions. This is especially true when used in conjunction with new shipboard iCER (internal exhaust gas recirculation) systems, as traditional wastewater treatment equipment struggles to meet the requirements of integration and intelligentization. Therefore, technological improvements and upgrades are needed.

[0068] Specifically, conventional marine sewage storage containers are typically sealed, box-like structures. Even if they incorporate biodegradation capabilities, they only serve a simple purpose of storage and initial degradation. During storage, domestic sewage, due to microbial activity, produces large amounts of harmful gases, which can harm crew health and the marine environment. Furthermore, these devices have low biodegradation efficiency, making it difficult to fully decompose organic matter and other pollutants in the sewage. Direct discharge still seriously pollutes marine ecosystems. Furthermore, currently available marine biodegradation devices primarily utilize fixed biofilm processes or activated sludge processes, typically treating sewage through multi-stage filtration and aeration biodegradation. However, these bio-filler layers have a simple structure and limited microbial attachment area, resulting in decreased treatment efficiency over time. Furthermore, existing devices generally lack intelligent control systems, preventing them from automatically adjusting operating parameters based on changes in sewage load. Consequently, over-aeration or insufficient oxygen supply often occur during actual ship operation. These issues are particularly prominent when used in conjunction with ship-based iCER systems, which consume significant energy and are complex, requiring the sewage treatment equipment to possess greater adaptability and stability.

[0069] The following combination Figures 1 to 8 , describing embodiments of the present invention.

[0070] According to an embodiment of the present invention, on the one hand, a biodegradable sewage treatment container for iCER water treatment is provided, comprising a base frame 1, a sedimentation and filtration component 2, a biodegradation mechanism 3 and a gas treatment device 4, wherein the sedimentation and filtration component 2 is fixedly connected to the top of the base frame 1, the biodegradation mechanism 3 is fixedly connected to the top of the base frame 1, the biodegradation mechanism 3 is communicated with the sedimentation and filtration component 2, and the gas treatment device 4 is communicated with the biodegradation mechanism 3; wherein the biodegradation mechanism 3 comprises a shell 31 fixedly connected to the base frame 1 at the bottom, an aeration mechanism 32 arranged on the shell 31 and communicated with the interior of the shell 31, a back plate 33 fixedly connected to the interior of the shell 31, a mounting frame 34 fixedly connected to the back plate 33, and a multi-layer biological filler layer 35 fixedly connected to the mounting frame 34; the gas treatment device 4 comprises an exhaust pipe 41 connected to the shell 31 at one end, a cylinder 42 connected to the other end of the exhaust pipe 41, a gas filter component 43 fixedly connected to the inner cavity of the cylinder 42, an exhaust hood 44 connected to the gas outlet end of the cylinder 42, and a fan 45 fixedly connected to the exhaust hood 44.

[0071] In this embodiment, the sewage treated by the sedimentation and filtration assembly 2 enters the outer shell 31 of the biodegradation mechanism 3, and the aeration mechanism 32 introduces air into the interior of the outer shell 31. The multi-layer biological filler layer 35 provides space for microorganisms to attach and grow. Under the action of air, the microorganisms are in full contact with the sewage and degrade the pollutants in the sewage. The harmful gases generated during the biodegradation process rise to the top of the outer shell 31, enter the cylinder 42 through the exhaust pipe 41, and after being purified by the gas filter assembly 43 in the cylinder 42, they are discharged through the exhaust hood 44 under the action of the fan 45.

[0072] Among them, the multi-layer biological filler layer 35 cooperates with the air introduced by the aeration mechanism 32 to greatly increase the contact area between microorganisms and sewage, significantly improves the degradation efficiency of pollutants, and makes it easier for treated sewage to meet discharge or reuse standards; the gas treatment equipment 4 can collect and purify harmful gases in a timely manner through the cooperation of the exhaust pipe 41, cylinder 42, gas filter component 43, exhaust hood 44 and fan 45, avoiding their accumulation in the outer shell 31 and causing pressure increase, ensuring the safe operation of the container at normal pressure, while preventing harmful gases from polluting the environment, ensuring the stable operation of the iCER water treatment system and the safety of the marine environment.

[0073] In one embodiment, Figure 7 As shown, the gas filter assembly 43 includes a fixing frame 431, a connecting column 432 and a filler adsorption layer 433. The fixing frame 431 is fixedly connected to the inner cavity of the cylinder 42, and the connecting column 432 is fixedly connected to the fixing frame 431 on the side close to the gas outlet end of the cylinder 42. The filler adsorption layer 433, the activated carbon filter layer 434 and the catalytic oxidation material layer 435 are sequentially sleeved on the surface of the connecting column 432 along the side close to the gas outlet end of the cylinder 42.

[0074] In this embodiment, when the harmful gases generated during the biodegradation process enter the cylinder 42 through the exhaust pipe 41, they will first contact the filler adsorption layer 433 on the surface of the connecting column 432. The filler adsorption layer 433 will first adsorb the large molecular impurities and some odors in the gas; the gas that has undergone preliminary treatment continues to flow and reaches the activated carbon filter layer 434. The activated carbon filter layer 434, with its rich pore structure, further adsorbs the small molecular harmful gases and residual odors in the gas; the remaining harmful gases that are difficult to adsorb will flow through the catalytic oxidation material layer 435. The catalytic oxidation material layer 435 oxidizes and decomposes these harmful gases into harmless substances through chemical reactions.

[0075] The gas filter assembly 43 can purify harmful gases layer by layer through the sequential action of the filler adsorption layer 433, the activated carbon filter layer 434 and the catalytic oxidation material layer 435, and comprehensively remove all kinds of harmful substances and odors in the gas. The purified gas can be discharged through the exhaust hood 44 under the action of the fan 45, effectively avoiding the pollution caused by the direct discharge of harmful gases to the environment. At the same time, it prevents the accumulation of harmful gases in the container and causes pressure increase, ensuring the safe operation of the container at normal pressure, and providing strong support for the stable operation of the iCER water treatment system.

[0076] In one embodiment, Figure 1 As shown, the aeration mechanism 32 includes an air pump 321 fixedly connected to the outer shell 31, a delivery pipe 322 connected to the air outlet end of the air pump 321, an air inlet pipe 323 connected to the air inlet end of the air pump 321, and a diverter pipe 324 connected to the air outlet end of the delivery pipe 322. The air outlet end of the diverter pipe 324 passes through the outer shell 31 and extends to its inner cavity.

[0077] In this embodiment, an air pump 321 draws in air through an air inlet pipe 323. The air is processed by the air pump 321 and then enters a delivery pipe 322. The delivery pipe 322 then delivers the air to a diversion pipe 324. The outlet end of the diversion pipe 324 extends into the inner cavity of the housing 31, directing the air into the interior of the housing 31. This aeration mechanism 32 can provide sufficient air around the biological filler layer 35 within the housing 31. The air forms bubbles within the housing 31 and fully contacts the sewage flowing through the multiple biological filler layers 35. This provides a suitable oxygen environment for the microorganisms growing and multiplying on the biological filler layers 35, meeting the microorganisms' oxygen needs when degrading pollutants in the sewage. This in turn enhances the activity and metabolic capacity of the microorganisms, improves the degradation efficiency of pollutants such as organic matter in the sewage, ensures the efficiency of the biodegradation process, and helps the treated sewage more easily meet discharge or reuse standards.

[0078] In one embodiment, Figures 2 to 4As shown, the sedimentation and filtration assembly 2 includes a tank body 21, a driving member 23, a rotating shaft 24, a cleaning frame 25, a filtering mechanism 26, a connecting pipe 27, and a delivery pump 28. A water inlet pipe 22 is provided at the top of the tank body 21. The driving member 23 is disposed outside the tank body 21. One end of the rotating shaft 24 is fixedly connected to the output end of the driving member 23. The other end of the rotating shaft 24 passes through the side wall of the tank body 21 and extends into the interior of the tank body 21. The cleaning frame 25 is located inside the tank body 21 and fixedly connected to the rotating shaft 24. The filtering mechanism 26 is fixedly connected to the inner cavity of the tank body 21. The cleaning frame 25 is in surface contact with the filtering mechanism 26. The inlet end of the connecting pipe 27 is connected to the tank body 21. The delivery pump 28 is connected between the outlet end of the connecting pipe 27 and the housing 31. The driving member 23 is a motor.

[0079] In this embodiment, sewage in the iCER water treatment system flows into the tank body 21 through the water inlet pipe 22 at the top of the tank body 21. The driving member 23 drives the rotating shaft 24 and the cleaning frame 25 fixed to the rotating shaft 24 to rotate inside the tank body 21. The cleaning frame 25 contacts the surface of the filter mechanism 26 in the inner cavity of the tank body 21 and cleans the filter mechanism 26 during the rotation process. The sewage flows through the filter mechanism 26 in the tank body 21. After being filtered by the filter mechanism 26, it is transported to the housing 31 through the connecting pipe 27 under the action of the delivery pump 28. The effect is that the water inlet pipe 22 facilitates the smooth flow of sewage into the tank body 21, and the filtering mechanism 26 can effectively intercept and filter various impurities in the sewage, reducing the processing burden of the subsequent biodegradation mechanism 3; the cleaning frame 25 continuously cleans the filtering mechanism 26 driven by the driving member 23 and the rotating shaft 24, which can prevent impurities from accumulating and clogging the filtering mechanism 26, maintain its filtering performance, and ensure that the filtering process is stable and efficient; the delivery pump 28 stably delivers the filtered sewage to the outer shell 31 through the connecting pipe 27, providing a suitable treatment object for the biodegradation link, thereby improving the treatment efficiency and effect of the entire sewage treatment container, and helping sewage to more easily meet the discharge or reuse standards.

[0080] Furthermore, the filtering mechanism 26 includes a fixed frame 261, a coarse filter screen 262, a fine filter screen 263 and a fiber filter screen 264. The fixed frame 261 is fixedly connected to the tank body 21, the coarse filter screen 262 is fixedly connected in the fixed frame 261, the fine filter screen 263 is located downstream of the coarse filter screen 262 and is fixedly connected to the inner cavity of the tank body 21, and the fiber filter screen 264 is located downstream of the fine filter screen 263 and is fixedly connected to the inner cavity of the tank body 21; wherein, the cleaning rack 25 is in contact with the surface of the coarse filter screen 262.

[0081] After the sewage enters the tank body 21, it first flows through the coarse filter 262 in the fixed frame 261. The coarse filter 262 intercepts larger particles of suspended matter in the sewage. The sewage then flows to the fine filter 263 located downstream of the coarse filter 262. The fine filter 263 further filters medium-sized particles of impurities. The sewage then continues to flow to the fiber filter 264 downstream of the fine filter 263. The fiber filter 264 intercepts tiny particles and colloidal substances. During the sewage filtration process, the cleaning rack 25 contacts the surface of the coarse filter 262 to continuously clean the coarse filter 262.

[0082] In this filtering mechanism 26, the coarse filter 262, the fine filter 263 and the fiber filter 264 constitute a three-stage progressive filtering system, which can remove impurities of different particle sizes in the sewage layer by layer, greatly reduce the impurity content in the sewage, reduce the processing pressure for the subsequent biodegradation mechanism 3, and improve the overall sewage treatment efficiency; the cleaning rack 25 is in contact with the coarse filter 262 for cleaning, which can prevent the coarse filter 262 from being blocked by the intercepted impurities, maintain its filtration transparency, ensure the stable filtration process, and eliminate the need for frequent manual cleaning, thereby reducing maintenance costs and allowing the filtered sewage to enter the biodegradation link in a more suitable state, helping the treated sewage to meet the standards more easily.

[0083] In one embodiment, Figure 1 As shown, the bottom of the cylinder 42 is fixedly connected to the support base 5, and the bottom of the support base 5 is fixedly connected to the shell 31.

[0084] The support base 5 is provided to fixedly connect the bottom of the cylinder 42 to the outer shell 31 through its own structure, thereby providing a stable support for the cylinder 42 and enabling the cylinder 42 to maintain a stable position during operation of the equipment.

[0085] It enhances the stability of the overall structure of the gas treatment equipment 4, especially when the ship may encounter complex environments such as bumps and vibrations during navigation, and can effectively prevent the cylinder 42 from shaking or displacing, ensuring the sealing and stability of the connection parts such as the exhaust pipe 41 and the cylinder 42, and the cylinder 42 and the exhaust hood 44, ensuring the continuous and stable progress of the gas treatment process, and avoiding the leakage of harmful gases due to the shaking of the cylinder 42.

[0086] In one embodiment, Figure 1As shown, a drain pipe 6 with a valve is connected to one side of the bottom of the housing 31. Once the sewage within the housing 31 of the biodegradation mechanism 3 has been treated and meets the standards, the operator can open the valve on the drain pipe 6 to allow the treated sewage to exit the housing 31 through the valve. The valve allows for flexible control of the opening and closing of the drain, allowing the operator to adjust the timing and amount of drainage based on actual conditions, ensuring that only qualified sewage is discharged and preventing the direct discharge of substandard sewage. The drain pipe 6 provides a channel for the treated sewage to exit the equipment smoothly, enabling its discharge or reuse, and ensuring the integrity of the entire sewage treatment process.

[0087] In one embodiment, Figure 1 As shown, a heater 7 and a liquid level sensor 8 are fixedly connected to the top of the shell 31. The heater 7 can heat and adjust the internal environment of the shell 31 of the biodegradation mechanism 3, and the liquid level sensor 8 monitors the sewage level in the shell 31 in real time and transmits the monitored data to the relevant control system. Among them, the heater 7 can provide a suitable temperature environment for the microorganisms in the shell 31, especially under low temperature conditions, to avoid the decrease in microbial activity due to excessively low temperature, thereby ensuring the efficient progress of the biodegradation process; the liquid level sensor 8 monitors the liquid level in real time, so that the control system can automatically adjust the equipment operating parameters according to the liquid level information, such as reducing the aeration volume to save energy when the liquid level is low, and increasing the aeration volume to meet the degradation needs of microorganisms when the liquid level rises, thereby realizing intelligent regulation of equipment operation, improving energy utilization efficiency and the stability of sewage treatment, and helping the entire sewage treatment container to better adapt to the operating requirements of the iCER water treatment system.

[0088] Furthermore, a control panel 9 is fixedly connected to the surface of the housing 31 . An adjustment knob is provided on the surface of the control panel 9 , and the control panel 9 is electrically connected to the liquid level sensor 8 and the air pump 321 .

[0089] The liquid level sensor 8 transmits the real-time monitoring data of the sewage level in the housing 31 to the control panel 9 electrically connected to it. The control panel 9 automatically adjusts the operating parameters of the air pump 321, which is also electrically connected to it, based on the liquid level information. At the same time, the operator can manually adjust the equipment operating parameters through the adjustment knob on the surface of the control panel 9. The effect is that the control panel 9 receives the data from the liquid level sensor 8 and automatically adjusts the air pump 321, realizing the intelligent operation of the equipment. When the liquid level is low, the aeration volume of the air pump 321 is reduced or aeration is suspended to save energy. When the liquid level rises, the aeration volume is increased to meet the needs of microbial degradation. The adjustment knob facilitates the operator to manually intervene according to the actual sewage situation and treatment needs, ensuring that the equipment operating parameters are adapted to different sewage treatment scenarios, improving the flexibility and controllability of the equipment, ensuring the efficient and stable progress of the biodegradation process, and contributing to better sewage treatment results.

[0090] According to an embodiment of the present invention, on the other hand, a sewage treatment method is provided, which is used in a biodegradable sewage treatment container for iCER water treatment, comprising the following steps:

[0091] After the sewage enters the tank 21, it is filtered by the sedimentation filter assembly 2, and then enters the housing 31;

[0092] The sewage flows through the gaps between the multi-layer biological filler layers 35, and at the same time, air is injected into the multi-layer biological filler layers 35 through the aeration mechanism 32, providing oxygen for the microorganisms to degrade pollutants;

[0093] The gas generated by the decomposition enters the cylinder 42 through the exhaust pipe 41 , is filtered by the gas filter assembly 43 , and is finally discharged by the fan 45 .

[0094] Specifically, this embodiment provides a specific implementation method:

[0095] In the iCER water treatment system, sewage from the water treatment unit first flows into the tank body 21 through the water inlet pipe 22. The interior of the tank body 21 is composed of a three-stage filtration system consisting of a coarse filter 262, a fine filter 263, and a fiber filter 264. The sewage flows from top to bottom under the action of gravity. The coarse filter 262 intercepts larger suspended particles, the fine filter 263 further filters medium-sized particle impurities, and the fiber filter 264 intercepts tiny particles and colloidal substances. During this process, the driving member 23 drives the rotating shaft 24 and the cleaning frame 25 to rotate. The elastic scraper on the cleaning frame 25 is in close contact with the coarse filter 262, continuously removing attached impurities, maintaining the filter transparency, and preventing clogging. The filtered sewage passes through the connecting pipe 27 and, under the action of the delivery pump 28, flows steadily into the outer shell 31.

[0096] After the sewage enters the outer shell 31, it flows through multiple layers of biological filler layers 35 in sequence. The gaps between adjacent biological filler layers 35 form water flow channels, allowing the sewage to fully contact the biological filler. At the same time, the air pump 321 inhales air through the air inlet pipe 323. After the impurities are filtered out by the air filter, the air enters the inner cavity of the outer shell 31 along the delivery pipe 322 and the diversion pipe 324, and is finally sprayed out from the nozzle 325 in a dispersed manner. The sprayed air forms a large number of tiny bubbles in the sewage, which are evenly distributed around the biological filler layer 35, providing sufficient oxygen for microorganisms. In a suitable oxygen environment, the biological filler layer 35 is made of porous polymer material. Its unique porous structure provides a huge specific surface area, providing sufficient attachment space for microorganisms, allowing a large number of microbial flora to grow and reproduce on its surface. These microbial flora include a variety of microorganisms with different metabolic functions, achieving the degradation and purification of pollutants in the sewage.

[0097] During the biodegradation process, the decomposition of organic matter in the sewage will produce harmful gases. These harmful gases rise to the top of the container and enter the cylinder 42 through the exhaust pipe 41. The gas filter component 43 in the cylinder 42 purifies the harmful gases. The filler adsorption layer 433 first adsorbs large molecular impurities and some odors. The activated carbon filter layer 434, with its rich pore structure, further adsorbs small molecular harmful gases and residual odors. The catalytic oxidation material layer 435 oxidizes and decomposes the remaining difficult-to-adsorb harmful gases into harmless substances through chemical reactions. The purified gas is discharged from the equipment through the exhaust hood 44 under the action of the fan 45 in the exhaust hood 44, avoiding the accumulation of harmful gases in the container and causing pressure increase, ensuring the safe operation of the equipment at normal pressure, and preventing harmful gases from leaking and polluting the environment.

[0098] The liquid level sensor 8 monitors the sewage level in real time and transmits the data to the control panel 9. The control system automatically adjusts the equipment operating parameters based on the liquid level information: when the liquid level is low, the aeration volume of the air pump 321 is reduced or aeration is suspended to save energy. When the liquid level rises, the aeration volume is increased to meet the needs of microbial degradation. In addition, the operator manually and accurately adjusts the equipment operating parameters, such as aeration intensity and gas treatment progress, according to the actual sewage situation and treatment requirements through the adjustment knob on the control panel 9, to realize the intelligent operation of the equipment and ensure that the ship's sewage is treated efficiently and stably.

[0099] Although the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention. Such modifications and variations are all within the scope defined by the appended claims.
