It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0024] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0025] An embodiment of the present invention provides an environmentally friendly storage device for a railway construction camping vehicle, which includes: a box body 1; a squat toilet 11 arranged in the box body 1, and the squat toilet 11 is installed on the inner bottom wall of the box body 1; wherein a storage box 12 is installed on the inner side wall of the box body 1, and a separation component and a filter component are arranged in the storage box 12; the separation component is located on a side of the storage box 12 close to the squat toilet 11, and the solid waste and liquid in the flushing water can be separated by the separation component to achieve the function of solid-liquid separation; the filter component is located on one side of the separation component in the storage box 12, and the flushing water after solid-liquid separation can be deeply purified by the filter component to remove residual suspended matter to ensure the clarity and hygiene of the outlet water.

[0026] It should be noted that the box 1, as the external structure of the entire device, provides space to accommodate and support other components. The squat toilet 11 is set on the inner bottom wall of the box 1 for users to use the toilet. The storage box 12 is installed on the inner wall of the box 1 for collecting and treating flushing water. The separation component is located on the side of the storage box 12 close to the squat toilet 11, which separates the solid waste from the liquid in the flushing water to achieve solid-liquid separation. This helps to reduce the burden of subsequent processing steps and improve purification efficiency. The filter component is located on one side of the separation component in the storage box 12, and deeply purifies the flushing water after solid-liquid separation to remove residual suspended matter. This ensures the clarity and hygiene of the effluent, making it suitable for reuse or safe discharge.

[0027] In an embodiment of the present invention, the separation component includes a first sewage tank 2 installed on the inner wall of a storage box 12, and the first sewage tank 2 is located on a side close to the squat toilet 11, a second sewage tank 21 is installed on the side of the storage box 12 located on the first sewage tank 2, and a first water outlet is opened at the top of the first sewage tank 2 and the second sewage tank 21 on a side relatively close to each other, an intermediate tank 22 is installed on the side of the second sewage tank 21 away from the first sewage tank 2, a second water outlet is opened on the side relatively close to the second sewage tank 21 and the intermediate tank 22, and a security filter is installed in the second water outlet, a lifter 3 is installed on one side of the storage box 12, and the lifter 3 is located on a side close to the squat toilet 11, the water outlet end of the squat toilet 11 is connected to the water inlet end of the lifter 3, and the water outlet end of the lifter 3 passes through the inner wall of the storage box 12 through a pipe and is connected to the first sewage tank 2.

[0028] It should be noted that: the first sewage tank 2 is installed on the inner wall of the storage box 12, located on the side close to the squat toilet 11. The first sewage tank 2 is used to perform the initial solid-liquid separation on the flushing water, and separate the solid waste from the liquid. The second sewage tank 21 is installed in the storage box 12, located on one side of the first sewage tank 2. The second sewage tank 21 is used to perform a secondary solid-liquid separation on the supernatant after the initial separation, and further remove the residual solid particles. The first water inlet is opened at the top of the side relatively close to the first sewage tank 2 and the second sewage tank 21, which is used to connect the first sewage tank 2 and the second sewage tank 21, so that the supernatant can flow from the first sewage tank 2 to the second sewage tank 21. The intermediate tank 22: installed in the storage box 12, located on the side of the second sewage tank 21 away from the first sewage tank 2. The intermediate tank 22 is used to temporarily store the supernatant after the secondary separation, and quantitatively lift it to the biochemical tank through a water pump. The second water inlet is opened on the side relatively close to the second sewage tank 21 and the intermediate tank 22, and is used to connect the second sewage tank 21 and the intermediate tank 22. The safety filter is installed in the second water inlet, and is used to precisely filter the supernatant after the secondary separation, remove suspended matter and large particle impurities, and protect the subsequent processing equipment. The safety filter is a mature existing technology and will not be further described here. The lifter 3 is installed on one side of the storage box 12, located on the side close to the squat toilet 11. The lifter 3 is used to lift and transport toilet water and waste. The water outlet end of the lifter 3 passes through the inner wall of the storage box 12 through a pipe and is connected to the first sewage tank 2. The lifter 3 lifts the toilet water and waste to a certain height, and then transports them to the first sewage tank 2 through a pipe for initial solid-liquid separation.

[0029] In an embodiment of the present invention, the filtration assembly includes a biochemical pool 4 installed on one side of the intermediate pool 22, and a lifting pump 41 is installed on the inner top wall of the storage box 12. The input end of the lifting pump 41 extends to the bottom of the intermediate pool 22 through an inlet pipe, and the output end of the lifting pump 41 extends to the top of the intermediate pool 22 through an outlet pipe. Micro-electrolysis filler is filled in the biochemical pool 4.

[0030] It should be noted that the biochemical pool 4 is connected to one side of the intermediate pool 22 for biochemical treatment of the supernatant. The micro-electrolysis filler filled in the biochemical pool 4 produces strong oxidants such as hydroxyl radicals through micro-electrolysis, which can efficiently degrade organic matter in sewage, such as BOD5 (biochemical oxygen demand for five days) and CODcr (chemical oxygen demand). The lifting pump 41 is installed on the inner top wall of the storage box 12, and is used to lift the supernatant in the intermediate pool 22 to the biochemical pool 4. The lifting pump 41: As a key device of the filtering component, the lifting pump 41 extracts the supernatant from the bottom of the intermediate pool 22 through the water inlet pipe, and transports the supernatant to the biochemical pool 4 through the water outlet pipe. The setting of the lifting pump 41 ensures that the supernatant can enter the biochemical pool 4 smoothly and provides the necessary lifting pressure. The design of the water inlet pipe and the water outlet pipe ensures that the lifting pump 41 can efficiently extract and transport the supernatant. The water inlet pipe extends to the bottom of the middle pool 22 to ensure that sufficient supernatant can be extracted; the water outlet pipe extends to the top of the middle pool 22 to ensure that the supernatant can be transported to the biochemical pool 4.

[0031] In an embodiment of the present invention, a ceramic membrane pool 42 is installed on one side of the biochemical pool 4, and the biochemical pool 4 is connected to the bottom of the ceramic membrane pool 42 on a relatively close side. A first air pump 43 is installed on the inner top wall of the storage box 12. The output end of the first air pump 43 extends to the bottom of the biochemical pool 4 and the ceramic membrane pool 42 respectively through two air pipes, and a ceramic membrane bioreactor is installed at the bottom of the ceramic membrane pool 42.

[0032] It should be noted that: Ceramic membrane pool 42: installed on one side of the biochemical pool 4, used for membrane filtration treatment of sewage after biochemical treatment. The biochemical pool 4 is connected to the bottom of the ceramic membrane pool 42 relatively close to one side, ensuring that the sewage after biochemical treatment can flow into the ceramic membrane pool 42 by gravity. The first air pump 43 provides aeration to the biochemical pool 4 and the ceramic membrane pool 42 through the air pipe, and provides oxygen in the biochemical pool 4 to maintain the activity and reproduction of microorganisms, while stirring and mixing the liquid to promote full contact between microorganisms and organic matter; the turbulence of the water flow is increased in the ceramic membrane pool 42, providing additional driving force to help the liquid pass through the membrane assembly better and improve the filtration efficiency. The ceramic membrane bioreactor is an existing technology, which specifically adopts a hollow flat ceramic membrane to perform membrane permeation suction filtration treatment on sewage. The filtration pore size of the ceramic membrane is 0.1 micron, which can effectively intercept tiny particles and organic matter to ensure the clarity and sanitary safety of the effluent.

[0033] In an embodiment of the present invention, an ozone catalytic pool 44 is installed on one side of the ceramic membrane pool 42, and a suction pump 45 is installed on the inner top wall of the storage box 12. The input end of the suction pump 45 extends into the ceramic membrane pool 42 through a suction pipe, and the output end of the suction pump 45 extends into the ozone catalytic pool 44 through a suction pipe. A second air pump 46 is installed on the inner top wall of the storage box 12, and the output end of the second air pump 46 extends to the bottom of the ozone catalytic pool 44 through an ozone tube. An ozone generator is connected to the ozone tube, and the ozone catalytic pool 44 is filled with ozone filler.

[0034] It should be noted that the suction pump 45 is a key device for connecting the ceramic membrane pool 42 and the ozone catalytic pool 44. The suction pump 45 extracts treated water from the ceramic membrane pool 42 through the suction pipe and transports the treated water to the ozone catalytic pool 44 through the suction pipe. The setting of the suction pump 45 ensures that the treated water can smoothly enter the ozone catalytic pool 44 and provides the necessary suction pressure. The second air pump 46 and the ozone generator transport ozone to the ozone catalytic pool 44 through the ozone pipe. Ozone is a strong oxidant that can react with pollutants such as organic matter, bacteria and viruses in sewage to achieve deep oxidation, deodorization and disinfection. The ozone generated by the ozone generator is transported by the second air pump 46 to ensure the uniform distribution and effective utilization of ozone in the ozone catalytic pool 44. The ozone filler is filled in the ozone catalytic pool 44, which can enhance the oxidation capacity of ozone and promote the reaction of ozone with pollutants in sewage. The setting of the ozone filler improves the treatment efficiency and effect of the ozone catalytic pool 44 and ensures the hygienic safety of the effluent.

[0035] The working principle of the environmentally friendly storage device for the railway construction camping car provided by the present invention is as follows: After the user uses the squat toilet 11 to go to the toilet, the flushing water and the dirt enter the lifter 3 through the vacuum or pressure system, and the lifter 3 lifts the mixture to an appropriate height, and then transports it to the first sewage tank 2 through a pipeline for initial solid-liquid separation. In the first sewage tank 2, the solid waste is initially separated from the liquid, and then the supernatant enters the second sewage tank 21 for secondary solid-liquid separation to further remove the residual solid particles. The supernatant after the secondary separation is finely filtered through the security filter to remove suspended matter and large particle impurities, and then temporarily stored in the intermediate tank 22. The lifting pump 41 lifts the supernatant in the intermediate tank 22 to the biochemical tank 4 for subsequent treatment. In the biochemical tank 4, the supernatant is micro-electrolyzed by the micro-electrolysis filler, which effectively degrades organic matter in the sewage, such as BOD5 and CODcr. The treated sewage flows into the ceramic membrane pool 42 by gravity, and the first air pump 43 provides aeration to the biochemical pool 4 and the ceramic membrane pool 42 through the air pipe to provide oxygen, stir and prevent precipitation. The ceramic membrane bioreactor performs membrane filtration treatment on the sewage, intercepts tiny particles and organic matter, and ensures the clarity and sanitary safety of the effluent. Subsequently, the suction pump 45 pumps the treated water in the ceramic membrane pool 42 into the ozone catalytic pool 44. The second air pump 46 and the ozone generator transport ozone to the ozone catalytic pool 44 through the ozone pipe, and the ozone reacts with the pollutants in the sewage to achieve deep oxidation, deodorization and disinfection. The ozone filler further enhances the oxidation capacity of ozone and promotes the reaction of ozone with pollutants in the sewage. The effluent after ozone catalytic treatment can be recycled for flushing toilets, thereby achieving efficient utilization of water resources and environmentally friendly emissions.
