[0045] like Figures 1 to 9 As shown, a preferred embodiment of the present invention provides a post station system for recycling and reusing rural domestic sewage, which includes a post station module 1 and a sewage treatment module 2:

[0046] The post station module 1 includes a post station body 11, a power generation module 12, an energy storage module 13 and a water resource reuse module 14; the post station body 11 includes a plurality of building facilities and public facilities for providing services to passengers; the power generation module 12 includes a plurality of solar power generation groups 121 for obtaining solar energy; the energy storage module 13 includes a battery pack and a power distribution cabinet arranged at the post station body 11, and the energy storage module 13 is electrically connected to the water resource reuse module 14 and the sewage treatment module 2; the water resource reuse module 14 includes an irrigation component 141, a fire protection component 142 and a flushing component 143 arranged at the post station body 11;

[0047] The sewage treatment module 2 includes an integrated sewage treatment device 21, a first storage tank 22, a second storage tank 23, a third storage tank 24 and an artificial wetland 25; the integrated sewage treatment device 21 is arranged on the side of the station body 11 close to the village, and the integrated sewage treatment device obtains and treats domestic sewage from multiple villages through pipelines, and the output ends of the integrated sewage treatment device 21 are respectively connected to the first storage tank 22 and the artificial wetland 25; the first storage tank 22, the second storage tank 23, and the third storage tank 24 are all arranged underground in the station body 11, and the output end of the first storage tank 22 is respectively connected to the irrigation component 141 and the second storage tank, and the output end of the second storage tank 23 is respectively connected to the fire protection component 142, the flushing component 143 and the third storage tank 24, and the output end of the third storage tank 24 is connected to the artificial wetland 25;

[0048] The artificial wetland 25 includes a reservoir 259 and a plurality of connected and fixed installation barrels 251, the installation barrel 251 includes an outer shell 2511 and an inner shell 2512, a first cavity 2513 is formed in the middle of the inner shell 2512, a second cavity 2514, a third cavity 2515, a fourth cavity 2516 and a fifth cavity 2517 are formed between the outer shell 2511 and the inner shell 2512; the second cavity 2514, the third cavity 2515, the first cavity 2513, the fifth cavity 2517 and the fourth cavity 2516 are connected in sequence; the second cavity 2514, the third cavity 2515, the fourth cavity 2516 and the fifth cavity 2517 are all provided with filter fillers 252, and the first cavity 2513 is provided with a grading layer 253, a matrix layer 254, a soil layer 255 and a planting layer 256 from bottom to top;

[0049] An input interface 25141 and a diversion interface 25142 are provided at the bottom of the second cavity 2514. The input interface 25141 is used to connect to the integrated sewage treatment equipment and / or the third storage tank 24 to obtain sewage, and the diversion interface 25142 is used to connect to the diversion interface 25142 of other installation barrels 251; an output interface 25161 is connected to the bottom of the fourth cavity 2516, and the output interface 25161 is connected to the input interface 25141 of the second cavity 2514 of the water storage tank 259 or other installation barrels 251.

[0050] Specifically, in previous plans, sewage treatment in various villages was basically independent of each other, and there was no unified treatment site. This resulted in a large degree of dispersion of rural sewage treatment facilities, and each dispersed sewage treatment facility was often operated by the villagers themselves. Sewage treatment facilities require continuous investment in manpower, material resources, and energy, and are very dependent on external energy, as well as manpower and material investment. After a period of use, these sewage treatment facilities are often abandoned. If they are not maintained, serious blockage problems will occur, and the villagers will then return to the situation of arbitrarily discharging domestic sewage.

[0051] In the present invention, a post station can be set between multiple adjacent villages, preferably the post station is set near the national highway, connecting multiple villages through the national highway, and facilitating the passengers to rest and replenish supplies. When the post station is completed, the domestic sewage of each village can be guided to the integrated sewage treatment equipment 21 through the pipeline, wherein the integrated sewage treatment equipment 21 should be set at the rear of the post station away from the national highway, so as to avoid the integrated sewage treatment equipment 21 from affecting the post station body 11, and also facilitate the installation of other facilities at the bottom of the post station body 11. Among them, the post station body 11 can build a variety of buildings and public facilities to provide services for passengers according to planning requirements, and the power generation module 12 and the energy storage module 13 are used to provide energy for the service facilities and sewage treatment module 2 in the post station, reduce the external energy required for the post station to treat domestic sewage, and when necessary, the excess electricity can be uploaded to the power grid to subsidize the material demand and capital demand of the post station sewage treatment, reducing the dependence of the post station and the sewage treatment module 2 on external energy and materials, so that the post station can operate for a longer time, and can treat the sewage of the surrounding villages for a longer time.

[0052] Furthermore, in the present invention, after the integrated sewage treatment equipment 21 treats the domestic sewage, it will output the first treated water and the second treated water respectively, wherein the second treated water is more seriously polluted and will be discharged to the artificial wetland 25, and after deep treatment of microorganisms and aquatic plants, the first treated water is sequentially transported to the first storage tank 22 and the second storage tank 23, and finally merged into the artificial wetland 25 through the third storage tank 24. Among them, the first storage tank 22 and the second storage tank 23 are both arranged below the post station body 11, and the sewage therein is respectively used for the reuse of the irrigation component 141, the fire fighting component 142 and the flushing component 143 in the post station, so that the domestic sewage is fully reused, the reuse rate of the sewage is improved, and the waste of the first treated water is avoided. In some other embodiments, the water in the first storage tank 22 can be transported back to the village or the farm near the village after being treated again, as the domestic water and animal husbandry water of the village and the farm, so as to maximize the reuse rate of water resources. Of course, the water transported to the artificial wetland 25 is collected in the reservoir 259 after being treated by the artificial wetland 25, and the water in the reservoir 259 can also be directly used for farmland irrigation or production water in the farm, or for fishery farming. The income generated by farming can also be used to subsidize the operating consumption of the station module 1 and the sewage treatment module 2, further reducing the station's dependence on external energy materials, and ensuring that the station module 1 and the sewage treatment module 2 can operate stably for a long time.

[0053] In addition, for the assembly form of artificial wetlands, different numbers of installation barrels 251 can be connected in different ways according to actual purification needs. In one scheme, multiple purification groups in series can be set, and multiple installation barrels 251 are connected in parallel in each purification group, so as to achieve large-scale sewage purification and improve sewage treatment efficiency. In another preferred embodiment, different installation barrels 251 can be connected according to the pattern of the tree diagram, and the output interface 25161 of a single installation barrel 251 is connected to multiple lower-level installation barrels 251 through a pipeline, and the output interface 25161 of the lower-level installation barrel 251 is connected to multiple secondary installation barrels 251 through a pipeline. The installation barrels 251 at the same level are connected through the shunt interface 25142. Accordingly, in the assembly mode of the tree diagram, multiple reservoirs 259 can be set, and the amount of sewage that can be treated is larger than that of the first scheme.

[0054] Furthermore, in conventional artificial wetland schemes, with the continuous operation of artificial wetlands, artificial wetlands often have the problem of blockage. For the blockage problem, the existing technology generally backwashes or digs the wetland fillers and manually dredges, but both schemes are relatively complex and time-consuming and labor-intensive, and will affect the normal operation of sewage treatment. In the present invention, each installation barrel 251 is provided with an inner and outer double-layer structure, the inner first cavity 2513 is used as the main structure of the artificial wetland, and the four outer cavities can filter and treat the sewage entering the first cavity 2513 and the sewage discharged from the first cavity 2513, and the aggravation of the blockage state in the first cavity 2513 is avoided by multi-layer filtration. When cleaning is required, it is also possible to clean and replace the filter fillers 252 in the second cavity 2514 to the fifth cavity 2517 without digging the fillers and aquatic plants in the first cavity 2513, thereby reducing the difficulty of cleaning the artificial wetland, and the whole process is more time-saving and labor-saving, and more convenient and quick.

[0055] Among them, the setting of the diversion interface 25142 can greatly expand the applicability of the artificial wetland, and different numbers of installation barrels 251 can be connected according to actual needs, thereby improving the overall sewage treatment efficiency and treatment volume.

[0056] In some embodiments, the station body 11 includes one or more of a reception room 111, a parking lot 112, a sports field 113, an outdoor pavilion 114, street lights, and a green area 115;

[0057] The reception room 111 includes one or more of air-conditioning equipment, fresh air equipment and vending equipment. The parking lot 112 is equipped with charging piles. Monitoring equipment and environmental monitoring equipment are integrated on the lamp poles of the street lamps. The air-conditioning equipment, fresh air equipment, vending equipment, charging piles, street lamps, monitoring equipment and environmental monitoring equipment are all electrically connected to the energy storage module 13.

[0058] Specifically, under normal circumstances, the main body of the post station 11 needs to include a reception room 111, a parking lot 112, a sports field 113, an outdoor pavilion 114, street lights, and multiple green areas 115 and other building facilities, wherein the reception room 111 can be divided into a rest area, a sales area, and a toilet, and the rest area is equipped with air conditioning equipment and fresh air equipment to provide the most comfortable environment for passengers, convenient for passengers to rest, and the rest area can also be closed and a separate charging plan can be made to facilitate the operation of the subsidized post station, and the sales area can be placed with vending machines, or manual sales, and the income can also be used to subsidize the operation of the post station; and the parking lot 112 can be equipped with charging piles, which can replenish the energy of the new energy vehicles of the passengers, facilitating the travel of the passengers, and the charging of the charging piles can also be used to subsidize the operation of the post station. Of course, it should be noted that the electric energy of the energy storage module 13 is preferentially supplied to the sewage treatment module 2. Under the condition of ensuring the normal operation of the sewage treatment module 2, the excess electric energy will be used and sold to maintain and subsidize the normal operation of the post station.

[0059] In some embodiments, multiple solar power generation groups 121 are respectively arranged on the top of the reception room 111, the ceiling of the parking lot 112, the ceiling of the sports field 113, the top of the outdoor pavilion 114, and the top ground of the integrated sewage treatment equipment 21, and the solar power generation group 121 is electrically connected to the energy storage module 13.

[0060] Specifically, multiple solar power generation groups 121 are respectively arranged on the tops of different buildings of the station body 11, which can better and more fully collect solar energy to supply the operation of the station and reduce the station's dependence on external energy. In some embodiments, the solar power generation group 121 can rotate according to the different angles of sunlight to obtain more solar energy to meet the station's usage needs and power storage needs. The integrated sewage treatment equipment 21 is buried underground, and solar panels can be installed in batches on its upper part to fully utilize the land area to obtain solar energy. Only the maintenance entrance of the integrated sewage treatment equipment 21 needs to be left.

[0061] In some embodiments, the power generation module 12 further includes a first hydropower generation group 122 and a second hydropower generation group 123;

[0062] The first hydropower generation group 122 includes a water collection tank 1221, a drainage pipe 1222 and a first turbine generator 1223. The water collection tank 1221 is arranged on the top of the reception room 111 or the roof of the parking lot 112 or the roof of the sports field 113 or the top of the pavilion. The drainage pipe 1222 is used to connect the water collection tank 1221 with the third storage tank 24. The first turbine generator 1223 is arranged at the bottom of the drainage pipe 1222.

[0063] The second hydropower generation group 123 includes a second turbine generator 1231 , which is disposed in a drainage channel 1232 from the third storage tank 24 to the artificial wetland 25 .

[0064] Specifically, under normal circumstances, the power generation of the solar panel group is very unstable and often depends on the weather conditions. When the weather conditions are bad, the solar panel group can obtain less sunlight, especially in the case of many rainy days, the power generation efficiency of the power generation module 12 is low, and it is difficult to meet the use needs of the post station. Therefore, the present invention is provided with a first water conservancy power generation group 122 and a second water conservancy power generation group 123, wherein the first water conservancy power generation group 122 is provided with a plurality of groups according to the number of buildings of the post station body 11. When it rains, especially when it rains heavily, when rain falls on buildings such as the reception room 111 and the parking shed, the rain flows along the ridge toward the edge of the building, and then falls into the water collection tank 1221. Under the convergence of the water collection tank 1221, the rain flows into the drain pipe 1222. The falling of the rain drives the first turbine generator 1223 in the drain pipe 1222 to rotate, thereby being able to continuously generate electricity to make up for the energy gap that the solar power generation group 121 cannot generate electricity on rainy days. Similarly, in the case of heavy rain, the water in the third storage tank 24 overflows and flows through the drainage channel 1232 toward the artificial wetland 25. The flowing water will drive the second turbine generator 1231 in the drainage channel 1232 to rotate, thereby generating electrical energy to supplement the energy storage device. The greater the amount of rainwater, the higher the power generation efficiency of the second turbine generator 1231.

[0065] In some embodiments, the irrigation assembly 141 includes a first water pump 1411 disposed in the first storage tank 22, the output end of the first water pump 1411 is connected to an irrigation pipeline 1412, the irrigation pipeline 1412 is laid in the green area 115, and the irrigation pipeline 1412 is provided with an irrigation nozzle corresponding to the green area 115;

[0066] The firefighting assembly 142 includes a second water pump 1421 disposed in the second storage tank 23. The output end of the second water pump 1421 is connected to a firefighting pipeline 1422. The firefighting pipeline 1422 is laid on the top of the reception room 111, the parking lot 112 and the sports field 113. The firefighting pipeline 1422 is provided with a firefighting nozzle and a monitoring probe.

[0067] The flushing assembly 143 includes a third water pump 1431 disposed in the second storage tank 23. The output end of the third water pump 1431 is connected to a flushing pipeline 1432. The flushing pipeline 1432 is used for flushing the ground and building facilities in the post station.

[0068] The first water pump 1411 , the second water pump 1421 , and the third water pump 1431 are all electrically connected to the energy storage module.

[0069] Specifically, according to demand, the first water pump 1411 will draw water from the first storage tank 22 every day for irrigation of flowers, plants and trees in each green area 115 in the station to ensure the stability of the green environment in the station, and avoid the trouble and cost of manual irrigation, so that the green plant environment in the station can be automatically maintained in a good state. When it rains, the first water pump 1411 will not start to reduce energy consumption. The fire-fighting pipeline 1422 is installed on the top of each building in the post station, and detects the fire situation through monitoring probes. When a fire occurs, the second water pump 1421 will start quickly to draw water from the second storage tank 23 and spray it to the fire point through the fire sprinkler, so as to curb the spread of the fire. Of course, under normal circumstances, fires will not easily occur, so the water in the second storage tank 23 is also used for sanitary water in the post station, mainly for flushing and cleaning the main buildings and roads in the post station to keep the post station clean and tidy. The flushing pipeline 1432 can be connected to a hose to flush various locations in the post station. Furthermore, when the fire cannot be contained by the fire sprinkler alone, the hose can also be connected to the flushing pipeline 1432, and then the output end of the hose can be aimed at the fire point to achieve more efficient fire extinguishing. Furthermore, due to the particularity of the second storage tank 23, the water in the first storage tank 22 needs to be discharged into the second storage tank 23 for storage in a timely manner after treatment to ensure that the water level in the second storage tank 23 is always above the preset water level. Accordingly, the second storage tank 23 is much larger than the first storage tank 22.

[0070] In some embodiments, the water resource recycling module 14 further includes a water heater assembly 15 disposed in the station body 11, the input end of the water heater assembly 15 is connected to the second storage tank 23, and a reverse osmosis water purification device 151 is disposed in the water heater assembly 15. Specifically, the station often needs to provide passengers with water of drinking quality, especially hot water, so the water heater assembly 15 is disposed in the reception room 111 of the station, and the water heater assembly 15 directly obtains water resources from the second storage tank 23, and further performs reverse osmosis filtration on the obtained water resources to ensure that the water output by the water heater assembly 15 reaches drinking quality and meets the drinking needs of passengers.

[0071] In some embodiments, a primary filtering device 26 is provided between the first storage tank 22 and the second storage tank 23;

[0072] The third storage tank 24 includes a storage tank body and a water collection channel 241. The water collection channel 241 is arranged on the ground of the station body 11 and is used to collect surface water of the station body 11 to the storage tank body. The storage tank body is provided with a fourth water pump 242. The output end of the fourth water pump 242 is connected to the first storage tank 22 through a pipeline.

[0073] Specifically, since the water in the first storage tank 22 and the second storage tank 23 is used in different directions, a primary filtering device 26 needs to be installed between the two storage tanks to treat the water quality. Of course, a first sewage filter processor 28 is also installed between the integrated sewage treatment equipment 21 and the first storage tank 22.

[0074] In addition, a water collection channel 241 is set on the ground of the station body 11, and rainwater can be collected into the third storage tank 24 on rainy days. On the one hand, the third storage tank 24 can be flushed, and all the water in the third storage tank 24 can be flushed into the artificial wetland 25. On the other hand, more rainwater can be collected to increase the flow rate and flow rate of water in the drainage channel 1232, thereby improving the power generation efficiency of the second turbine generator 1231. Of course, the flushing water output from the flushing pipeline 1432 can also be collected in the third storage tank 24 through the water collection channel 241 for reuse, which fully avoids the waste of water resources.

[0075] Furthermore, the fourth water pump 242 arranged in the storage tank body of the third storage tank 24 can pump the water in the third storage tank 24 into the first storage tank 22 when there is insufficient water resources in the first storage tank 22 or the second storage tank 23, thereby ensuring normal water use in the first storage tank 22 and the second storage tank 23. Of course, the output end of the fourth water pump 242 is also connected to the second sewage filter processor 29.

[0076] In some embodiments, the second cavity 2514, the third cavity 2515, the fourth cavity 2516 and the fifth cavity 2517 are disposed around the first cavity 2513;

[0077] A first partition 257 is provided between the second cavity 2514 and the third cavity 2515. The top height of the first partition 257 is lower than the top height of the inner shell 2512, so that the sewage in the second cavity 2514 can overflow into the third cavity 2515.

[0078] The inner shell 2512 is provided with a water inlet 25121 on the side wall facing the third cavity 2515, and the top height of the water inlet 25121 is lower than the top height of the first partition 257, so that the sewage in the third cavity 2515 can overflow into the first cavity 2513;

[0079] The side wall of the inner shell 2512 facing the fifth cavity 2517 is provided with a water outlet 25122, and the water outlet 25122 is provided at the bottom of the side wall of the inner shell 2512, so that the sewage in the first cavity 2513 can flow into the fifth cavity 2517;

[0080] A second partition 258 is provided between the fifth cavity 2517 and the fourth cavity 2516 , and the top height of the second partition 258 is lower than the top height of the inner shell 2512 , so that the sewage in the fifth cavity 2517 can overflow into the fourth cavity 2516 .

[0081] Specifically, in actual use, the sewage in the integrated sewage treatment equipment or the third storage tank or other installation barrel 251 enters the second cavity 2514 of the installation barrel 251 through the pipeline. Since the input interface 25141 is arranged at the bottom of the second cavity 2514, with the continuous input of sewage, the sewage spreads upward from bottom to top in the second cavity 2514, and gradually passes through the filtering filler 252 in the second cavity 2514 to complete the preliminary filtration of the sewage. When the height of the sewage is higher than the first partition plate 257, the sewage in the second cavity 2514 overflows into the third cavity 2515; the sewage first flows along the vertical direction toward the bottom of the third cavity 2515 at the edge of the third cavity 2515, and then spreads upward from the bottom to complete the second filtration of the sewage. As the amount of sewage in the third cavity 2515 increases, the water level gradually reaches the water inlet 25121, and the sewage in the third cavity 2515 flows into the third cavity 2515 through the water inlet 25121. The sewage enters the first cavity 2513; after entering the first cavity 2513, it is processed from top to bottom by the aquatic plants in the planting layer 256 and the microorganisms in the soil layer 255, and then passes through the matrix layer 254 and the grading layer 253 downward in turn to complete the third filtration treatment of the sewage, and then the sewage enters the bottom of the fifth cavity 2517 through the outlet 25122; the sewage spreads upward from bottom to top in the fifth cavity 2517, and passes through the filter filler 252 in the fifth cavity 2517 to complete the fourth filtration treatment of the sewage, and then the sewage overflows into the fourth cavity 2516 through the second partition 258, and the sewage moves downward from top to bottom in the fourth cavity 2516, and passes through the filter filler 252 in the fourth cavity 2516 to complete the fifth filtration treatment of the sewage, and finally the sewage passes through the output interface 25161 connected to the bottom of the fourth cavity 2516, and the treated sewage is discharged to other installation barrels 251 at the lower level or directly to the water storage tank 259.

[0082] It should be noted that, in some specific embodiments, a transition chamber 2518 is separated in the third cavity 2515, and the transition chamber 2518 is arranged between the second cavity 2514 and the third cavity 2515, and a transition port 25181 is provided at the bottom of the transition chamber 2518 to communicate with the bottom of the third cavity 2515; under this structure, the sewage overflowing from the second cavity 2514 will first flow into the transition chamber 2518, and then flow into the bottom of the third cavity 2515 through the transition port 25181. Finally, the sewage is completely filtered from bottom to top in the third cavity 2515, thereby preventing impurities and dirt from being filtered in the upper part of the third cavity 2515 and then being carried out by the sewage accumulated from bottom to top.

[0083] In addition, the filter fillers 252 in the second cavity 2514 to the fifth cavity 2517 all include multiple filler layers, the size of the filter particles of the fillers in each filler layer is different, and the arrangement of the filler layers of the filter fillers 252 in the second cavity 2514 to the fifth cavity 2517 is different, and the arrangement of the filler layers is determined according to the flow direction of the sewage. In a specific embodiment, the filter fillers 252 in the second cavity 2514 to the fifth cavity 2517 all include a primary filter layer 2521, a secondary filter layer 2522 and a tertiary filter layer 2523, and the particle sizes in the primary filter layer 2521, the secondary filter layer 2522 and the tertiary filter layer 2523 are successively reduced, that is, the particle size in the primary filter layer 2521 is the largest, the gap is also the largest, and the filtering effect is the worst, while the particle size in the tertiary filter layer 2523 is the smallest, the gap is also the smallest, and the filtering effect is better. Then in the second cavity 2514, the third cavity 2515 and the fifth cavity 2517, the distribution of the packing layers from bottom to top is the primary filter layer 2521, the secondary filter layer 2522 and the tertiary filter layer 2523, while the distribution of the packing layers from bottom to top in the fourth cavity 2516 is the third filter layer, the second filter layer and the first filter layer.

[0084] Furthermore, after the installation barrels 251 at each level in the artificial wetland treat the domestic sewage, the water will eventually be discharged into the corresponding reservoir 259, and the output end of the reservoir 259 is connected to the irrigation ditch of the farmland. The reservoir 259 can be used as a pond for fishery farming, or it can be connected to the irrigation ditch for irrigation of farmland, and it can also be connected to animal husbandry for water supply for animal husbandry. In special locations, it can also be connected to rivers for water storage and flood discharge. Among them, irrigation water and fishery farming can generate income to subsidize the stable operation of the post station module 1 and the sewage treatment module 2.

[0085] In addition, multiple rows of protective forests can be planted between the artificial wetland 25 and the post station to block the line of sight and ensure the beauty of the overall environment of the post station.

[0086] In some embodiments, the water resource recycling module 14 includes a sanitary component 16, which also includes a fifth water pump 161 arranged in the second storage tank 23. The output end of the fifth water pump 161 has a sanitary water pipeline 162. The sanitary water pipeline 162 is arranged in the bathroom of the reception room 111. The output end of the sanitary water pipeline 162 is connected to the integrated sewage treatment equipment 21.

[0087] Specifically, the water used in the bathroom in the reception room 111 can use the water resources in the second storage tank 23, but the drainage of the bathroom is different from others. The drainage of the bathroom needs to be discharged into the integrated sewage treatment equipment 21, and then processed by the first sewage filter processor 28 before it can be discharged into the first storage tank 22.

[0088] In some embodiments, the sewage treatment module 2 further includes a pretreatment facility 27, which is arranged near each village, and the output end of the pretreatment facility 27 is connected to the integrated sewage treatment equipment 21 through a pipeline. The pretreatment facility 27 can collect domestic sewage from each village and pre-treat the collected domestic sewage, thereby reducing the processing pressure and processing energy consumption of the integrated sewage treatment equipment 21, and ensuring that the integrated sewage treatment equipment 21 can operate for a long time and stably.

[0089] In summary, the embodiment of the present invention provides a station system for recycling and reusing rural domestic sewage. By setting up multiple storage tanks, it can fully reuse the treated domestic sewage, avoiding the waste of the first treated water. At the same time, the second treated water generated can be discharged into the artificial wetland 25 and can also be used for farmland irrigation and fishery breeding. The generated income can be used to subsidize the operation of the station module 1 and the sewage treatment module 2. The various power generation devices of the power generation module 12 in the station module 1 can also meet the energy consumption of the sewage treatment module 2, and can also generate excess electricity for sale to subsidize the operation of the station and the sewage treatment module 2. While ensuring the long-term and stable operation of the sewage treatment work, it can also reduce the dependence of the station module 1 and the sewage treatment module 2 on external energy and resources, thereby reducing its overall operating cost.

[0090] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
