Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and more specifically to a farming system for the on-site resource utilization of domestic wastewater. Background Technology

[0002] Most rural domestic sewage is discharged directly into rivers or underground through pipes without treatment. Untreated sewage carries nutrients such as nitrogen, phosphorus, and potassium. Random discharge not only causes eutrophication and ecological pollution of water bodies, but also wastes valuable resources needed for agricultural production.

[0003] In the prior art, there are some devices applied to rural domestic sewage treatment. For example, Chinese invention patent application number CN202410738825.7 discloses a rural domestic sewage treatment device and its usage method. In this application, sewage is treated by filtration, which can quickly remove some solids from the sewage during the treatment process. However, in rural domestic sewage, the solids are mostly usable nutrients, such as food scraps, and some other substances, such as silt or plastic fragments. If all the solids are filtered out, these solid nutrients will generally be wasted and cannot be effectively utilized.

[0004] Based on this, this application proposes a farming system for the on-site resource utilization of domestic sewage, which can effectively utilize solid nutrients in domestic sewage while also effectively removing other solid substances. Summary of the Invention

[0016] A further technical solution involves an opening on the upper side of the filter box, with a support rod in the center of the opening. Both sides of the filter box opening have mesh doors for sealing the opening, with one side of each door hinged to the edge of the opening. The traction rope of the traction machine is connected to the support rod. A flushing pump is installed on the outside of the collection box, with its outlet inside the collection box and its inlet inside the treatment tank. The lower half of the connection is sealed with a filter screen. A third telescopic rod is horizontally installed on the side of the collection box away from the treatment tank. The telescopic end of the third telescopic rod passes through a through hole into the collection box and is connected to a vertically positioned sleeve inside the collection box. A fourth telescopic rod is installed at the upper end of the sleeve, with its output shaft facing downwards. An adjusting block is slidably connected inside the sleeve.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: By setting up a filter screen box, domestic sewage can first enter the filter screen box when entering the first treatment tank. After being filtered by the filter screen box, solid matter is filtered out inside the filter screen box. By setting up a stirring tube, when the piston is moved by the first telescopic rod, the elastic membrane will move in the direction of the piston's movement. This allows the elastic membrane to stir the active sludge at the bottom of the first treatment tank, so that the active sludge can enter the filter screen box during the stirring process. In this way, the active sludge can biologically treat food residues and other substances in the filter screen box, gradually decomposing them. After decomposition, the active sludge can flow out of the filter screen box under the action of the stirring tube. The substances that the active sludge cannot decompose will continue to remain in the filter screen box. This can effectively utilize food residues and other fixed substances and avoid waste.

Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0036] Figures 1 to 14 The image shows an embodiment of the present invention.

[0037] Example 1:

[0038] A farming system for on-site resource utilization of domestic sewage includes a treatment tank 101, a fertilizer tank, and a planting greenhouse 301. The treatment tank 101 contains a treatment pool 103. An inlet pipe 106 connected to the treatment pool 103 is located on the side of the treatment tank 101. A filter screen box 107 is located inside the treatment pool 103, and the inlet pipe 106 and the filter screen box 107 are internally connected. Activated sludge is located inside the treatment pool 103. A stirring pipe 108 is installed on the side of the treatment tank 101, with one end of the stirring pipe 108 placed inside the treatment pool 103. An elastic membrane 109 is installed at the opening of the stirring pipe 108. A piston 110 is slidably mounted inside the stirring pipe 108, along with a first telescopic rod 111 for driving the piston 110. The treatment pool 103 is connected to the first inlet pipe 209 of the fertilizer tank via a third connecting pipe 114. The fertilizer outlet pipe 214 of the fertilizer tank is connected to the water supply pipeline of the planting greenhouse 301. The water supply pipeline of greenhouse 301 includes drip irrigation pipes, circulating water pipes, and irrigation pipes. Drip irrigation pipes are used for drip irrigation in ordinary planting areas, circulating water pipes are used for nutrient solution recycling in soilless cultivation areas, and irrigation pipes are used for irrigation in paddy fields when planting rice or crops with high water requirements.

[0039] The stirring tube 108 includes a first tube body 115 and a second tube body 116. Near the bottom of the treatment tank 103, an adjustment chamber 118 is formed by a partition 117. An adjustment hole 119 is provided on the side of the partition 117 facing the filter box 107. A mounting hole 120 communicating with the adjustment chamber 118 is provided on the side of the treatment box 101. The mounting hole 120 and the adjustment hole 119 are aligned. The first tube body 115 is placed inside the adjustment chamber 118, and the end of the second tube body 116 is installed inside the mounting hole 120. The first tube 115 and the second tube 116 are connected by a flexible connecting section 121. The end of the first tube 115 away from the second tube 116 is placed in the adjusting hole 119, and the outer side of the end is connected to the inner wall of the adjusting hole 119 by a flexible water-proof sheet 122. An adjusting ring 123 is arranged around the outer side of the first tube 115 in the adjusting cavity 118. A gap is left between the inner wall of the adjusting ring 123 and the first tube 115. Several second telescopic rods 124 facing the first tube 115 are arranged around the inner wall of the adjusting ring 123. The flexible connecting section 121 connects the first pipe body 115 and the second pipe body 116, allowing adjustment of the orientation of the pipe opening of the first pipe body 115. Multiple second telescopic rods 124 facilitate rapid adjustment, thereby agitating different positions in the treatment tank 103. This allows the activated sludge within the treatment tank 103 to move more effectively, and, driven by the elastic membrane 109, the water in the first filtration tank impacts the filter screen box 107, uniformly mixing the activated sludge and solid matter within the filter screen box 107, facilitating biological treatment. Simultaneously, the treated solid matter is filtered out of the filter screen box 107 under the impact. By installing an isolation cover 117, the regulating chamber 118 prevents the first pipe body 115, the second tank, and the regulating ring 123 from directly contacting domestic sewage.

[0040] A plurality of sliding holes 125 aligned with the first tube 115 are provided on the inner wall of the adjusting ring 123. Each sliding hole 125 contains a sliding rod 126. A second push plate 127 is provided at one end of the sliding rod 126 located inside the adjusting ring 123. A first spring 128 is sleeved between the second push plate 127 and the inner wall of the adjusting ring 123. The output end of the second telescopic rod 124 is attached to the outer wall of the first tube 115 via the first push plate 129. By omitting the first spring 128 and the sliding rod 126, the first tube 115 can be in a neutral position when the second telescopic rod 124 is not in operation.

[0041] At least one vent pipe 130 is provided at a position outside the processing box 101 for the second pipe body 116, connecting the inside and outside of the second pipe body 116. A first solenoid valve 131 is provided on the vent pipe 130 to control its opening and closing. By providing the vent pipe 130 and the solenoid valve, the piston 110... Figure 2 As shown, after moving to the right, the elastic membrane 109 moves to the right in the middle under the action of the piston 110. After moving a certain distance, the vent pipe 130 is opened by the first solenoid valve 131, so that the sewage on the left side of the elastic membrane 109 can be quickly flushed out.

[0042] One end of the inlet pipe 106, placed inside the treatment tank 103, is bent upwards to form an insertion section 132. The bottom of the filter screen box 107 is recessed to form an insertion groove 133. The bottom of the insertion groove 133 has an insertion hole 134 that communicates with the interior of the filter screen box 107. The insertion hole 134 matches the insertion section 132. A traction machine 135 for lifting the filter screen box 107 is mounted on the treatment box 101 at the toothed position of the treatment tank 103. By providing the insertion section 132 and the insertion groove 133, the filter screen box 107 can be quickly installed during vertical movement.

[0043] A pressure sensor is installed inside the stirring tube 108.

[0044] A collection box 136 is provided on the side of the top of the treatment box 101. The collection box 136 has an opening on its upper side and is connected to the treatment pool 103 of the treatment box 101 through a connecting port 137. A guide rail 138 is mounted above the treatment box 101 and the collection box 136. A movable seat 139 is movably mounted on the guide rail 138 along its length. A moving component is provided inside the movable seat 139 to drive the movable seat 139 to move along the length of the guide rail 138. A fixing bar 140 is provided on the lower side of the movable seat 139, and an electromagnet is mounted on the fixing bar 140. An adsorption block that is magnetically connected to the electromagnet is installed on the filter box 107. A traction machine 135 is installed on the upper side of the movable seat 139. The traction rope of the traction machine 135 is connected to the filter screen box 107. A rotating mechanism for driving the guide rail 138 to rotate is installed at the end of the processing box. Two fixing bars 140 are provided, arranged parallel to each other at intervals. A first guide ring 142 is provided between the two fixing bars 140. A cantilever rod 143 is provided on the upper side of the movable seat 139 above the fixing bars 140. A second guide ring 144 is provided at the end of the cantilever rod 143 above the first guide ring 142. The traction rope of the traction machine 135 passes through the second guide ring 144 and the first guide ring 142 in sequence and is connected to the filter screen box 107. By setting up the collection box 136, it is convenient to collect non-degradable plastics or other impurities in the filter screen box 107. The collection process is as follows: When the filter box 107 needs cleaning, the traction machine 135 moves the filter box 107 upward, so that the filter box 107 is moved to the lower side of the fixing bar 140. The electromagnet attracts the adsorption block to fix the filter box 107 to the fixing bar 140. Then, the moving seat 139 moves the filter box 107 through the connecting port 137 into the collection box 136. The rotating mechanism drives the moving seat 139 to rotate along the axis of the guide rail 138, causing the filter box 107 to flip over so that the top of the filter box 107 faces downward, thus allowing the impurities inside the filter box 107 to be poured out. By setting the first guide ring 142 and the second guide ring 144, the filter box 107 can be moved upward.

[0045] The movable base 139 is provided with a drive hole 145 that passes through both the front and rear ends. The movable component includes two support bars 146 vertically arranged on opposite sides of the guide rail 138. The upper and lower ends of the two support bars 146 are respectively connected to the upper and lower walls of the drive hole 145. A rolling wheel 141 is installed on the upper side of the guide rail 138 between the two support bars 146. The rolling wheel 141 is in rolling connection with the upper side of the guide rail 138. At least two rolling wheels 141 are arranged along the length of the guide rail 138. A rack 147 is arranged on the lower side of the guide rail 138 along its length. A first gear 148 is vertically rotatably arranged on the lower side of the two support bars 146 on the guide rail 138. The first gear 148 meshes with the rack 147. A first servo motor 149 is installed on the outer side of one of the support bars 146. The output shaft of the first servo motor 149 is connected to the first gear 148 for transmission. The upper side of the guide rail 138 is convex, and the circumferential surface of the rolling wheel 141 is concave. When the movable seat 139 needs to be driven, the first servo motor 149 is activated, which drives the first gear 148 to rotate. Through the meshing relationship between the first gear 148 and the rack 147, the movable seat 139 can move linearly along the guide rail 138. The rolling wheels 141 cooperate with the first gear 148 to move along the upper and lower sides of the guide rail 138, ensuring the movable seat 139 can move stably along the guide rail 138, and preventing the movable seat 139 from deviating. By setting a protrusion on the upper side of the guide rail 138, it cooperates with the recess of the rolling wheels 141, allowing the rolling wheels 141 to move linearly along the guide rail 138.

[0046] The rotating mechanism includes a rotating box 150, a rotating cavity 151 inside the rotating box 150, a first rotating hole 152 connected to the rotating cavity 151 at a position aligned with the guide rail 138, the end of the guide rail 138 being rotatably disposed in the first rotating hole 152, a support plate 153 being vertically disposed inside the rotating cavity 151, a second rotating hole 154 aligned with the first rotating hole 152 being disposed on the support plate 153, a rotating shaft 155 being rotatably disposed inside the second rotating hole 154, one end of the rotating shaft 155 being coaxially connected to the end of the guide rail 138, and a second gear 156 being sleeved on the other end of the support plate 153 on the side away from the first rotating hole 152, a second servo motor 157 being installed inside the rotating cavity 151, a third gear 158 being installed on the output shaft of the second servo motor 157, and the third gear 158 being meshed with the second gear 156. When the movable seat 139 moves the filter box 107 into the collection box 136, the second servo motor 157 drives the third gear 158 to rotate. The rotation of the third gear 158 drives the second gear 156 to rotate, which in turn drives the rotating shaft 155 to rotate. The rotation of the rotating shaft 155 drives the guide rail 138 to rotate, thereby causing the movable seat 139 to flip over as a whole, so that the filter box 107 can rotate to the downward position.

[0047] The filter screen box 107 has an opening on its upper side, with a support rod 159 in the middle of the opening. Both sides of the opening are equipped with screen doors 160 for closing the opening. One side of each screen door 160 is rotatably connected to the edge of the opening via a hinge. The traction rope of the traction machine 135 is connected to the support rod 159. A flushing pump 161 is installed on the outside of the collection box 136. The outlet of the flushing pump 161 is located inside the collection box 136, and the inlet of the flushing pump 161 is located in the treatment tank 10. Inside the 3rd chamber, the lower half of the connecting port 137 is blocked by a filter screen 162; a third telescopic rod 163 is horizontally installed on the side of the collection box 136 away from the treatment box 101. The telescopic end of the third telescopic rod 163 passes through the through hole 164 into the collection box 136, and a vertically arranged sleeve 165 is connected inside the collection box 136. A fourth telescopic rod 166 is installed at the upper end of the sleeve 165. The output shaft of the fourth telescopic rod 166 is set downward, and an adjusting block 167 is slidably connected up and down inside the sleeve 165. The lower end of the adjusting block 167 is connected to a mounting plate 168 below the sleeve 165. A mounting groove 169 is recessed on the side of the mounting plate 168 facing the third telescopic rod 163. The lower side of the mounting groove 169 is open. A connecting strip 171 is rotatably connected to the mounting groove 169 via a horizontally positioned rotating shaft 170. A rubber scraper 172 is connected to the side of the connecting strip 171 facing the third telescopic rod 163. A detection device connected to the mounting groove 169 is provided on the side of the mounting plate 168 away from the mounting groove 169. A detection column 174 is installed in the mounting hole 173. A detection hole 175 is provided at the end of the detection column 174 facing the mounting groove 169. A detection block 176 is slidably installed in the detection hole 175. A pressure sensor 177 is installed at the bottom of the detection hole 175 and is connected to the detection block 176 via a second spring 178. A discharge port 179 is provided at the bottom of the collection box 136 on the side away from the treatment box 101. The discharge port 179 is sealed by a sealing door 180. The sealing door 180 is rotatably installed at the position of the discharge port 179 via a hinge, and a sealing ring is provided on the edge of the sealing door 180. The sealing door 180 is locked to the discharge port 179 by a door lock, and the sealing ring seals the gap between the sealing door 180 and the discharge port 179 to prevent water leakage. The support rod 159 can be easily fixed to the traction rope. A hinge allows the mesh door 160 to rotate around the hinge, so that when the filter box 107 is inverted, the mesh door 160 rotates and opens around the hinge, thus emptying the impurities inside the filter box 107. The frame of the mesh door 160 is made of solid metal, giving it a certain weight so that it can close tightly when upright and open smoothly when inverted.By setting up a flushing pump 161, when impurities are poured into the collection tank 136, some activated sludge is inevitably carried along. To avoid wasting the activated sludge, the flushing pump 161 flushes the activated sludge off the impurities and re-enters the treatment tank 103. After the impurities in the collection tank 136 accumulate to a certain extent, the third telescopic rod 163 drives the rubber scraper 172 to remove the impurities from the collection tank 136. In the initial state, the third telescopic rod 163 is extended, close to the filter screen 162. By shortening the third telescopic rod 163, the rubber scraper 172 moves towards the discharge port 179, thereby discharging the impurities from the discharge port 179. To prevent the third telescopic rod 163 from being unable to shorten due to excessive weight from the accumulated impurities, thus damaging the third telescopic rod 163... The resistance experienced by the rubber scraper 172 is monitored by the cooperation of the detection column 174 and the detection block 176. During the movement of the rubber scraper 172, the adjusting block 167 is pushed to compress the second spring 178, thereby increasing the pressure value monitored by the pressure sensor 177. When the pressure value increases to a certain level, the shortening of the third telescopic rod 163 will stop, thus protecting the third telescopic rod 163. At this time, by extending one end of the third telescopic rod 163 and then shortening the fourth telescopic rod 166, the rubber scraper 172 is driven to move upward, thereby increasing the distance between the lower end of the rubber scraper 172 and the bottom of the filter box 107. This reduces the amount of debris scraped away by the rubber scraper 172 during its movement, thereby reducing resistance and protecting the third telescopic rod 163. Furthermore, the pressure sensor 177 can detect whether the lower side of the rubber scraper 172 is damaged. The determination method is as follows: after the impurities are cleaned, the extension length of the fourth telescopic rod 166 is such that the intact rubber scraper 172 contacts the bottom of the filter box 107. Assuming the pressure value generated during the movement of the intact rubber scraper 172 in contact with the bottom of the filter box 107 is A, if the pressure value generated by the pressure sensor 177 is much less than A, it indicates that the lower side of the rubber scraper 172 is broken or has significant damage, preventing effective contact between the lower side of the rubber scraper 172 and the filter box 107, or preventing effective movement of impurities after contact. In this case, replacement is necessary. If necessary, the ability of the damaged rubber scraper 172 to push impurities can be increased by extending the fourth telescopic rod 166.

[0048] Example 2:

[0049] An active fertilizer ecological tank includes a tank body 201 and a power unit 202. The tank body 201 is divided into an upper cavity 203 and a lower cavity 204 by a partition. A sludge return pipe 205 is installed in the lower cavity 204, and the upper end of the sludge return pipe 205 is connected to the bottom of the upper cavity 203. A liquid guide pipe 206 connected to the lower cavity 204 is installed in the upper cavity 203. An ejector 207 and a third water inlet pipe 208 are installed in the lower cavity 204. The power unit 202 is equipped with a first water inlet pipe 209, a second water inlet pipe 210, a filter 212, and a water pump. 213, the first inlet pipe 209 and the second inlet pipe 210 are respectively connected to both sides of the filter layer of the filter 212. The second inlet pipe 210 is connected to the inlet of the water pump 213. The outlet of the water pump 213 is connected to the ejector 207 through the first outlet pipe 211. The lower end of the sludge return pipe 205 is connected to the second inlet pipe 210. One end of the third inlet pipe 208 is placed below the water pump 213, and the other end is connected to the second inlet pipe 210. A fertilizer outlet pipe 214 connected to the upper cavity 203 is provided near the top of the tank 201. The filter 212 can effectively intercept impurities in the sewage. The filter 212 can be a self-cleaning screen. This application realizes the on-site resource utilization of agricultural sewage, turning sewage into efficient farmyard manure, which solves the problem of rural sewage treatment and provides high-quality farmyard manure for crop growth. The device utilizes a single water pump 213 to achieve aerobic aeration, anoxic mixing, and sludge return, resulting in low energy consumption and simple operation and maintenance. This fertilizer tank is specifically designed for rural wastewater resource utilization, converting wastewater into high-quality fertilizer through targeted microbial technology. It is suitable for rural settlements, small farms, and ecological parks. Targeted cultivation of aerobic microorganisms removes organic matter from wastewater, decomposing it into carbon dioxide and water. Simultaneously, it converts phosphorus in the wastewater into ionic forms easily absorbed by plants and nitrogen from nitrogen-containing organic matter into nitrate nitrogen easily absorbed by plants. The sludge from the cultivated microorganisms is fed into tank 201 for use. The resulting mixture flows through a guide pipe 206 into the upper chamber 203, where sedimentation separates the microorganisms from the water. The microorganisms then re-enter the biochemical system for further reaction. The supernatant, after disinfection, is used as a nutrient solution for hydroponic crops or for farmland irrigation, reducing fertilizer usage.

[0050] The liquid guide tube 206 includes a main liquid guide tube 215 for the water pump and a first liquid guide tube 216. The main liquid guide tube 215 for the water pump is vertically arranged in the upper cavity 203. The upper end of the main liquid guide tube 215 is close to the top of the upper cavity 203. The upper end of the main liquid guide tube 215 is open and the lower end is closed. The upper end of the first liquid guide tube 216 is connected to the main liquid guide tube 215 for the water pump, and the lower end is placed in the lower cavity 204.

[0051] A material blocking mesh 217 is installed at the lower end of the first liquid guide pipe 216. By setting up the material blocking mesh 217, small pieces of material that have not been completely decomposed can be prevented from entering the first liquid guide pipe 216, thus avoiding accumulation and blockage in the first liquid guide pipe 216 or the main liquid guide pipe 215 of the water pump.

[0052] The middle of the baffle is concave and funnel-shaped, and the upper end of the sludge return pipe 205 is connected to the upper side of the middle of the baffle. With the help of the funnel-shaped baffle, the sludge can settle in the upper cavity 203 and then gather towards the center of the baffle, which facilitates its return through the sludge return pipe 205 and back into the lower cavity 204 for biochemical reaction.

[0053] A vertically arranged suction pipe 218 is installed inside the tank 201. The upper end of the suction pipe 218 is located on the upper side of the tank 201, and the lower end passes through the upper cavity 203 and the partition in sequence, and then connects to the air inlet of the ejector 207 in the lower cavity 204. The ejector 207 is connected to a nozzle 219, which is located above the third water inlet pipe 208. By setting up the suction pipe 218, air can be drawn into the ejector 207, and after being drawn in by the water pump 213, it becomes the driving water for the ejector 207. The mixture passing through the ejector 207 forms a gas-water mixture with saturated dissolved oxygen under the action of the ejector 207.

[0054] The edge of the upper cavity 203 is connected to the top of the lower cavity 204 via an air guide tube 220, with the upper end of the air guide tube 220 positioned near the top of the upper cavity 203. By providing the air guide tube 220, air inside the lower cavity 204 can be discharged to the upper cavity 203 through the air guide tube 220 as the liquid gradually fills the lower cavity 204.

[0055] An inclined plate packing 221 is installed at the upper part of the upper cavity 203. A second liquid guide pipe 222 is horizontally arranged above the inclined plate packing 221. A liquid guide cover 223 is installed at the upper end of the main liquid guide pipe 215 of the water pump. One end of the second liquid guide pipe 222 is connected to the inside of the liquid guide cover 223, and the other end is connected to the cavity wall of the upper cavity 203. An outlet hole is provided on the lower side of the second liquid guide pipe 222. The main function of the inclined plate packing 221 is to improve the sedimentation capacity and efficiency of the upper cavity 203. The inclined plate packing 221 is mainly made of ethylene-propylene copolymer material. A sedimentation section with a reasonable sedimentation distance is set at the upper part, and the geometry is controlled at the lower part to form a stable contact sludge section at the lower part of the inclined plate. Through contact action and shallow pool sedimentation mechanism, the purpose of sludge and water separation is achieved. The inclined plate packing 221 is a multi-functional and efficient combination that is easy to install and disassemble. The inclined plate spacing is adjustable, the connection length is unlimited, and the packing support rod can be designed in various specifications and sizes to meet different parameter requirements, such as spacing and angle. By using a liquid guide cover 223 and a second liquid guide pipe 222, the mixed liquid entering the upper cavity 203 can be distributed to various positions of the inclined plate packing 221.

[0056] The cavity wall in the middle of the upper cavity 203 is configured as a frustum 229, with the diameter of the upper end of the frustum 229 being larger than the diameter of the lower end. Inclined plate packing 221 is installed on the frustum 229, and a through hole 230 is provided in the middle of the inclined plate packing 221. With the help of the frustum 229, the inclined plate packing 221 is installed at an angle, and during the sedimentation process, the sludge will gradually gather towards the center of the baffle, which facilitates the recovery of sludge.

[0057] The upper cavity 203 has an annular triangular weir trough 224 above the inclined plate packing 221. The fertilizer water outlet pipe 214 is located below the triangular weir trough 224, and the bottom of the triangular weir trough 224 is connected to the fertilizer water outlet pipe 214 through a connecting pipe 225. By setting the triangular weir trough 224, the upper clear liquid can enter the triangular weir trough 224 and then enter the fertilizer water outlet pipe 214 through the connecting pipe 225 for discharge. The discharged fertilizer water can be used as fertilizer after disinfection and sterilization.

[0058] The filter 212 has a filter chamber with a filter screen 227 as the filter layer. The filter screen 227 divides the filter chamber into an inner chamber and an outer chamber 226. The first inlet pipe 209 is connected to the inner chamber, while the second inlet pipe 210, the third inlet pipe 208, and the sludge return pipe 205 are all connected to the outer chamber 226. A sludge discharge pipe 228, which is connected to the inner chamber, is also connected to the filter chamber. By setting up the filter screen 227, sewage entering the second inlet pipe 210 can be intercepted in the inner chamber by the filter screen 227. When the filter 212 needs to be cleaned, sludge or sewage in the third inlet pipe 208 or the sludge return pipe 205 can flow back from the outer chamber 226 to the inner chamber to backwash the filter screen 227. The impurities from the backwash can be discharged through the sludge discharge pipe 228.

[0059] The wastewater resource utilization process of the sludge tank in this application is as follows: Step S1, adding sludge containing microorganisms into the upper cavity 203; Step S2, starting the water pump 213 to draw wastewater from the first inlet pipe 209 into the filter 212. After filtration, the wastewater, mixed with the sludge left from the sludge return pipe 205, enters the lower cavity 204 through the second inlet pipe 210 and the first outlet pipe 211, and is sprayed out through the jet ejector 207 and nozzle 219; Step S3, when there is initially no liquid in the lower cavity 204, all the liquid mixed with sludge will gradually fill the lower cavity 204 to carry out aerobic biochemical reaction. As the liquid in the lower cavity 204 increases, the liquid located below the nozzle 219... As the liquid oxygen in the filter is gradually depleted, an anaerobic biochemical reaction begins. The liquid below nozzle 219 enters the outer cavity 226 of filter 212 along the third inlet pipe 208 and mixes with sewage and sludge. In step S4, after the lower cavity 204 is filled with liquid, it enters the upper cavity 203 along the first guide pipe 216, the main guide pipe 215 of the water pump, and the second guide pipe 222 for sedimentation. In step S5, when the water level in the upper cavity 203 increases to the position of the triangular weir trough 224, the upper clear water enters the triangular weir trough 224 and is then discharged through the connecting pipe 225 and the fertilizer water outlet pipe 214 for use as fertilizer water after disinfection and sterilization.

[0060] Example 3:

[0061] A plate heat exchanger is installed on the inlet pipe 106. When the temperature inside the inlet pipe 106 is too high, the heat inside the inlet pipe 106 can be absorbed by the plate heat exchanger. The other end of the plate heat exchanger is connected to the hot water storage tank unit 305 or the vertical water wall unit 306 to heat the water inside the hot water storage tank unit 305 or the vertical water wall unit 306.

[0062] A modular heat storage and temperature regulation system is installed inside the planting greenhouse 301: it consists of a bottom hot water storage tank unit 305 and a vertical water wall unit 306; the fertilizer water outlet pipe 214 is connected to the vertical water wall unit 306; the bottom hot water storage tank unit 305 is assembled from multiple precast concrete water tank modules with top openings and is laid under the greenhouse floor; the vertical water wall unit 306 is constructed vertically along the inner wall of the greenhouse or independent support by multiple modular water tanks; the bottom water tank and the vertical water wall are interconnected by pipes to form a large-scale water heat storage structure, and the circulating water (fertilizer water) inside is the carrier of heat.

[0063] For the hydroponics area, a tidal binary cultivation module is used, which is set above the bottom hot water storage tank unit 305, including:

[0064] Planting trough 307: Used to hold lightweight cultivation substrate and plant crops.

[0065] Storage trough 308: Located directly below the planting trough 307, it is directly connected to the water distribution system at the upper end of the vertical water wall unit 306 and is used to receive and temporarily store temperature-controlled and nutrient-rich circulating water.

[0066] It also includes a tidal irrigation control system: controlled by a timer and a liquid level sensor, the nutrient solution stored in the lower trough 308 is periodically pumped into the upper planting trough 307 via a water pump 309, soaking the roots and substrate, and then drained back into the lower trough by gravity, forming a "tidal" rise and fall. The liquid level sensor is installed inside the upper planting trough 307.

[0067] The bottom of the planting trough 307 is equipped with drainage holes and a drainage pipe 310. The drainage holes are fitted with anti-clogging filters. The cultivation substrate of the planting trough 307 is a mixture of coconut coir and perlite, which combines water retention, air permeability, and adsorption properties, helping to further adsorb and transform nutrients and trace pollutants in the water during tidal processes. A second solenoid valve 311 is installed on the drainage pipe 310 to control its on / off state.

[0068] Water-heat-fertilizer synergistic supply mode: Temperature-controlled circulating water enters the tidal cultivation tank as a nutrient solution carrier, providing the roots with water, suitable temperature and dissolved nutrients during irrigation.

[0069] Purification and reflux mode: After being absorbed by crops and adsorbed by the substrate, the reflux liquid has a reduced content of nutrients such as nitrogen and phosphorus, and can be partially discharged to external ecological wetlands or returned to the front end of sewage treatment to achieve deep purification of water quality and salt balance within the system.

[0070] It also includes a photovoltaic power generation unit, whose output is used to power the circulating pump, tidal irrigation pump and controller in the system, thus realizing a closed loop in the energy section.

[0071] The system innovatively couples waste heat recovery from sewage, water body heat storage and temperature regulation with tidal irrigation technology, realizing "using water to carry heat, using water to carry fertilizer, and applying heat and fertilizer together", so that water, heat and fertilizer resources are highly coordinated in time and space, maximizing utilization.

[0072] Efficient and safe utilization and secondary purification of nutrients in wastewater:

[0073] The tidal dual cultivation system greatly optimizes the oxygen supply in the root zone through periodic immersion and drainage, avoiding the root zone hypoxia and salinization problems that may be caused by traditional sewage irrigation, and significantly improving the crop's nutrient absorption efficiency.

[0074] The cultivation substrate and the well-developed plant root system together form a "living biological filter" that further absorbs, adsorbs, and degrades the remaining nutrients and organic matter in the reflux liquid, achieving deep purification and quality improvement of wastewater treatment plant effluent and reducing the environmental risks of direct discharge.

[0075] It exhibits exceptional climate adaptability and production stability: the massive modular heat storage system effectively mitigates diurnal and seasonal temperature differences, creating a stable root zone temperature environment for the tidal cultivation system, making it particularly suitable for year-round production of high-value-added crops in cold and high-altitude regions.

[0076] Highly modular and intelligent: Both the heat storage body and the cultivation trough use standardized prefabricated components, supporting rapid construction; the intelligent system realizes unified decision-making for environmental control and water and fertilizer management, reducing management complexity and labor costs.

[0077] The system combines economic and ecological benefits: it significantly reduces or even eliminates the heating and fertilizer costs of greenhouses, and generates multiple revenues through the production of high-quality agricultural products, the sale of green electricity, and potential wastewater treatment services (purifying effluent), thus realizing a new model of three-industry integration of "wastewater treatment + clean energy + green agriculture".

[0078] Example 4: System construction and core component installation.

[0079] A waterproof membrane and insulation layer are laid on a leveled and compacted foundation. Precast concrete water tank modules (2m × 1m × 0.4m) are hoisted and assembled to form the bottom hot water storage tank. Vertical water wall modules are constructed along the north side of the greenhouse. Subsequently, a steel frame is erected above the bottom water tank, and tidal binary cultivation troughs are installed. Each cultivation trough unit is 1.5m long and 0.6m wide, with a lower trough volume of approximately 50L. Coconut coir and perlite are mixed in a 7:3 volume ratio and then filled into the upper trough.

[0080] Example 5: Water-Heat-Fertilizer Co-operation Process. Wastewater effluent (approximately 15°C) is transferred to the internal clean circulating water via a heat exchanger. During the day, the intelligent controller pumps the heated circulating water (approximately 20°C) into a heat storage tank. When the tidal irrigation cycle is triggered, the circulating water carrying heat and nutrients is first injected into the distribution pipes at the top of the vertical water wall, flowing by gravity into the lower tanks of each tidal cultivation unit. Once the lower tank level reaches the set value, the tidal pump starts, rapidly pumping nutrient solution at approximately 20°C into the upper tank, fully immersing the substrate and roots for 3-5 minutes, before draining it back into the lower tank. This process not only provides water and nutrients such as N, P, and K, but the warm irrigation solution also directly raises the root zone temperature, promoting nutrient absorption and microbial activity.

[0081] Example 6: Nutrient Utilization and Water Purification Effect. Taking lettuce cultivation as an example, in the system, pretreated domestic sewage effluent is used as a nutrient source. After one growth cycle (30 days), monitoring data shows:

[0082] The absorption and utilization rate of nitrogen and phosphorus by crops is about 25%-35% higher than that of traditional drip irrigation.

[0083] The total nitrogen (TN) and total phosphorus (TP) concentrations of the reflux liquid discharged from the tidal system are reduced by 40%-60% compared to the influent, and the chemical oxygen demand (COD) is reduced by more than 30%.

[0084] The refluxed liquid can be safely used to irrigate non-edible crops or returned to the upstream of wastewater treatment plants, effectively reducing the subsequent treatment load.

More specifically, various variations and modifications can be made to the components and / or layout of the subject matter combination within the scope of the disclosure, drawings, and claims.
