Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to integrated rural wastewater treatment equipment. Background Technology

[0002] In remote villages and towns, due to the limited population, centralized sewage treatment networks are generally not accessible. Even if sewage treatment networks could extend along main roads, the costs of installing pipelines and transporting and operating long-distance sewage pumping stations are very high. Consequently, most sewage in these villages and towns currently relies on natural infiltration into the soil around houses, which is detrimental to environmental cleanliness. Common sewage treatment methods involve purifying water through processes such as filtration, sedimentation, aeration, and biofilm filtration. However, these processes are lengthy, require frequent operation by staff, and occupy large areas, making them unsuitable for rural areas. To complete the above-mentioned process flow that meets the wastewater treatment standards, a large area of ​​land is required, and then filter tanks, sedimentation tanks, and aeration tanks are constructed. This undoubtedly increases the cost of rural wastewater treatment. In addition, domestic sewage contains a large amount of suspended solids, such as food scraps, fibers, and grease. Through the sedimentation process, these solids are separated into sediments. The removal of sediments can significantly reduce the load on subsequent treatment processes. However, most rural wastewater treatment equipment currently causes secondary turbulent mixing of sediments with the upper clarified water during the sediment removal process, which is not conducive to the efficient collection of sediments in sewage. Summary of the Invention

[0003] The purpose of this invention is to provide an integrated rural sewage treatment equipment to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] An integrated rural wastewater treatment system includes a housing. The interior of the housing, from right to left, comprises an anoxic zone, an anaerobic zone, an aerated aerobic zone, a sedimentation zone, a membrane filtration zone, and an equipment room. Multiple baffles (first and second types) are fixed at equal intervals within the anoxic and anaerobic zones. An aeration mechanism is fixed within the aerated aerobic zone. A sedimentation collection module is installed within the sedimentation zone. This module includes a V-shaped plate fixedly connected to the sedimentation zone, with two collection hoppers embedded on both sides of the V-shaped plate. A release valve is fixed below the V-shaped plate. The container is connected to the release pipe by an arc-shaped pipe. A sealing block 1 and a sealing block 2 are arranged on both sides of the V-shaped plate. A drive shaft is rotatably connected to the top of the sedimentation zone. A winding roller for pulling the sealing block 1 and the sealing block 2 up and down is fixed on the outside of the drive shaft. An air-push mechanism is provided above both sides of the V-shaped plate. A water inlet pipe is connected to one end of the box and a water delivery pipe 1 is connected to one end of the water inlet pipe. The top end of the water delivery pipe 1 is connected to the anaerobic zone and the bottom end of the water delivery pipe 1 is connected to the aeration aerobic zone.

[0006] Furthermore, a return channel is fixed between the top of the aeration aerobic zone and the sedimentation zone, one end of the return channel is connected to the anaerobic zone, and a second water supply pipe is fixedly connected to the outside of the first water supply pipe.

[0007] Furthermore, one end of the second water supply pipe is connected to two fixed connecting pipes, and the membrane filtration zone and the sedimentation zone are respectively connected to the corresponding connecting pipes.

[0008] Furthermore, the aeration mechanism includes multiple longitudinal pipes fixedly connected to the bottom surface of the aerobic aeration zone, transverse pipes connecting and fixing the ends of the multiple longitudinal pipes, aeration discs being fixedly connected at equal intervals on the outer side of the transverse pipes, and an air supply pipe being fixedly connected to the outer side of one of the transverse pipes, the air supply pipe being connected to the air outlet pipe of the aeration fan between the equipment.

[0009] Furthermore, a second motor for driving the transmission shaft to rotate is fixed on the outer side of the sedimentation zone, and multiple turns of rope are wound around the outer side of the take-up roller. Both ends of the rope pass through the V-shaped plate and the arc-shaped tube and are fixedly connected to the corresponding sealing block one or sealing block two.

[0010] Furthermore, the air-propulsion mechanism includes an air injection pipe that is inserted and fixed to the sedimentation zone. One end of the air injection pipe is connected and fixed to a limiting pipe one and a limiting pipe two. The bottom ends of the limiting pipe one and the limiting pipe two are respectively inserted into the corresponding positions inside the receiving hopper near the arc-shaped pipe. The limiting pipe one is slidably inserted into the sealing block one, and the limiting pipe two is slidably inserted into the sealing block two.

[0011] Furthermore, the bottom end of the release pipe is connected to and fixed with a discharge pipe, the top end of the release pipe is connected to and fixed with a frustum-shaped cylinder, and an auger is rotatably connected inside the release pipe.

[0012] Furthermore, the blades of the auger are provided with mesh holes, a motor is fixed at the bottom of the sedimentation zone to drive the auger to rotate, elastic cloth strips are fixed on both sides inside the sedimentation zone, and the sealing block is fixedly connected to the corresponding elastic cloth strip.

[0013] Furthermore, the top surface of the second sealing block is an inclined surface, and two side plates are fixed inside the sedimentation zone. The inner side of the side plates is provided with a notch for embedding and fixing with the V-shaped plate.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The horizontal container-like design reduces the project's footprint and eliminates the need for investment in basic infrastructure. Depending on water volume, wastewater can be collected by village or group, reducing the cost of entering the municipal sewer system and improving rural wastewater collection rates. If water quality or quantity changes, simply adding more containers solves the problem, avoiding secondary investment. Compared to structured wastewater treatment systems, the low-cost integrated wastewater treatment container reduces the professional requirements for personnel. Furthermore, the option to add an intelligent control module further reduces the professional requirements for operators. Therefore, the design and development of the low-cost integrated horizontal wastewater treatment container solves the problems of high investment costs and insufficient professional operation and maintenance, while the modular treatment method addresses the issue of low wastewater collection rates.

[0016] 2. The bottom of the anoxic zone and the anaerobic zone are connected. The anoxic zone is equipped with several anaerobic zone baffles, baffles 1 and 2. Baffles 2 are higher than baffles 1, and there is a gap between the bottom of baffles 2 and the box. Water entering one side of baffles 2 from the water supply pipe 1 will flow from its bottom to the position between baffles 1 and baffles 2, and then flow through baffles 1 to another space. The baffle guiding technology facilitates the formation of granular activated sludge flocs.

[0017] 3. The V-shaped plate design facilitates the collection of sediment along its surface into the hopper. A vibrating motor can be installed on the outside of the sedimentation zone to allow the sediment on the V-shaped plate to fall quickly into the hopper. The drive shaft rotates the winding roller to wind up the rope on one side of the V-shaped plate. The rope pulls the sealing block one and sealing block two down into the hopper, making it easy to push the collected sediment through the arc-shaped pipe to the release pipe. The auger inside the release pipe rotates to facilitate the transport of the sediment out.

[0018] 4. By wrapping the middle of the rope around the outside of the take-up roller multiple times, and pulling the two ends of the rope to the sealing blocks (including sealing block one and sealing block two, both of which are floatable on the water surface), when the take-up roller rotates and pulls one rope, the other rope is released by rotation. The rope in the pulling state has a downward reaction force on the drive shaft, and the rope in the released state, under the buoyancy of the float, pulls the take-up roller to rotate in the direction of rotation and winding, which can offset part of the reaction force on the drive shaft and help reduce the energy consumption of motor two.

[0019] 5. First, use rope traction to block the receiving hopper on one side of the V-shaped plate with the sealing block. Then, use an external rod-like tool to block the floating sealing block to the receiving hopper on the other side of the V-shaped plate. Next, use an external air pump to supply air to the air injection pipe. The airflow enters the sealed receiving hopper and the inside of the arc-shaped pipe, which facilitates the thorough flushing out of the sedimentation zone inside the arc-shaped pipe. At this time, the auger can be rotated in the reverse direction to squeeze the sediment into the frustum-shaped cylinder, so that the water remaining in the sediment can flow away through the release pipe first. Then, rotate the auger in the forward direction to concentrate and transport the sediment out. Attached Figure Description

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example 1

[0032] Please see Figure 1-10In this embodiment of the invention, the integrated rural sewage treatment equipment includes a housing 100. The housing 100 contains, from right to left, a hypoxic zone 110, an anaerobic zone 120, an aerobic zone 130, a sedimentation zone 140, a membrane filtration zone 150, a clear water zone 160, and an equipment room 170. Multiple baffles 121 and 122 are fixedly installed at equal intervals inside the hypoxic zone 110 and the anaerobic zone 120. An aeration mechanism 200 is fixed inside the aerobic zone 130. A sedimentation collection module 300 is installed inside the sedimentation zone 140. The sedimentation collection module 300 includes a V-shaped plate 310 fixedly connected to the sedimentation zone 140. Two receiving hoppers 320 are embedded and fixed on both sides of the V-shaped plate 310. A release pipe 330 is fixed below the 0. An arc-shaped pipe 331 is fixed between the receiving hopper 320 and the release pipe 330. A blocking block 340 and a blocking block 350 are arranged on both sides of the V-shaped plate 310. A drive shaft 400 is rotatably connected to the top of the sedimentation zone 140. A winding roller 410 for pulling the blocking block 340 and the blocking block 350 up and down is fixed on the outside of the drive shaft 400. An air-push mechanism 500 is set above both sides of the V-shaped plate 310. A water inlet pipe 600 is fixedly connected to one end of the box 100. A water delivery pipe 610 is fixedly connected to one end of the water inlet pipe 600. The top end of the water delivery pipe 610 is connected to the anaerobic zone 120, and the bottom end of the water delivery pipe 610 is connected to the aerated aerobic zone 130.

[0033] Specifically, the anoxic zone 110 is connected to the bottom of the anaerobic zone 120. The anoxic zone 110 contains several anaerobic zone 120 baffles 121 and 122. Baffle 122 is higher than baffle 121, and there is a gap between the bottom of baffle 122 and the housing 100. Water entering from the water supply pipe 610 onto one side of baffle 122 flows from its bottom to the area between baffle 121 and baffle 122, and then submerges the baffle. The sediment flows from 121 to another space. The baffle plate guide technology facilitates the formation of granular flocs from activated sludge bacteria. By arranging V-shaped plates 310 at the bottom of the sedimentation zone 140, the sediment falling onto the surface of the V-shaped plates 310 is collected inside the receiving hopper 320. The drive shaft 400 rotates the winding roller 410 to wind up and release the rope 411, so that the sealing blocks on both sides of the V-shaped plates 310 can alternately seal the receiving hopper 320, which facilitates the centralized transportation of sediment.

[0034] like Figure 2 and Figure 5As shown, in this embodiment, a return channel 131 is fixed between the top of the aeration aerobic zone 130 and the sedimentation zone 140. One end of the return channel 131 is connected to the anaerobic zone 120. A second water supply pipe 620 is fixedly connected to the outside of the first water supply pipe 610. The return channel 131 is used to pump the water from the sedimentation zone 140 to the anaerobic zone 120 for treatment. The first water supply pipe 610 is connected to the anaerobic zone 120 from a high position to facilitate the supply of water to the anaerobic zone 120. The second water supply pipe 620 is used to supply water to the membrane filtration zone 150 for membrane filtration.

[0035] like Figure 2 As shown, in this embodiment, one end of the water supply pipe 620 is connected to two fixed connecting pipes. The membrane filtration zone 150 and the sedimentation zone 140 are respectively connected to the corresponding connecting pipes, so as to facilitate the delivery of water to the membrane filtration zone 150 and the sedimentation zone 140.

[0036] like Figure 4 As shown, in this embodiment, the aeration mechanism 200 includes multiple longitudinal pipes 210 fixedly connected to the bottom surface of the aerobic aeration zone 130. Transverse pipes 220 are fixedly connected between the ends of the multiple longitudinal pipes 210. Aeration discs 230 are fixedly connected at equal intervals on the outer side of the transverse pipes 220. An air supply pipe 240 is fixedly connected to the outer side of one transverse pipe 220. The air supply pipe 240 is connected to the air outlet pipe of the aeration fan in the equipment room 170. The aeration fan supplies air to the multiple longitudinal pipes 210 and the transverse pipes 220, so that the aeration discs 230 can continuously aerate over a large area.

[0037] like Figure 7 and Figure 8 As shown, in this embodiment, a second motor 420 for driving the transmission shaft 400 to rotate is fixed on the outer side of the sedimentation zone 140. Multiple turns of rope 411 are wound around the outer side of the take-up roller 410. Both ends of the rope 411 pass through the V-shaped plate 310 and the arc-shaped tube 331 and are fixedly connected to the corresponding blocking block 340 or blocking block 350. Both ends of the rope 411 have branch ropes, so that one end of the rope 411 can simultaneously pull the blocking block 340 and the blocking block 350. Both the blocking block 340 and the blocking block 350 can float in the water.

[0038] like Figure 7 As shown, in this embodiment, the bottom end of the release pipe 330 is connected to and fixed with the discharge pipe 333, and the top end of the release pipe 330 is connected to and fixed with a frustum-shaped cylinder. The inside of the release pipe 330 is rotatably connected with an auger 332. When the auger 332 rotates in one direction, the sediment can be moved upward, and the water can be flowed away through the mesh of the auger 332 to separate water and sediment. When the auger 332 rotates in another direction, the sediment can be transported out through the discharge pipe 333.

[0039] like Figure 7As shown, in this embodiment, the blades of the auger 332 have mesh openings. A motor 142 for driving the auger 332 to rotate is fixed to the bottom of the sedimentation zone 140. Elastic cloth strips 141 are fixed to both sides inside the sedimentation zone 140. The sealing block 350 is fixedly connected to the corresponding elastic cloth strip 141. Refer to the instruction manual. Figure 7 During the downward movement of the second sealing block 350, the second sealing block 350, along with the elastic cloth belt 141, changes from a horizontal state to an inclined state, which facilitates the pouring of the sediment collected on the surface of the elastic cloth belt 141 onto the top of the second sealing block 350, making it convenient for the subsequent collection hopper 320 to collect the sediment. The mesh-like auger 332 facilitates water filtration, and the discharge pipe 333 is equipped with a valve inside, which can block the discharge pipe 333 if sediment is not discharged.

[0040] like Figure 9 As shown, in this embodiment, the top surface of the sealing block 350 is an inclined surface, and two side plates 143 are fixed on the inner side of the sedimentation area 140. The inner side of the side plate 143 is provided with a notch 1431 for embedding and fixing with the V-shaped plate 310. The inclined surface at the top of the sealing block 350 facilitates the sediment to be guided and transported along the inclined surface to the upper part of the receiving hopper 320 on the V-shaped plate 310. The notch 1431 allows the V-shaped plate 310 to be installed without gaps with the inner side of the box 100, preventing the sediment from falling below the V-shaped plate 310.

[0041] In practice, the inlet pipe 600 transports domestic wastewater to the transmission pipe 610, which then enters the anaerobic zone 120. The transmission pipe 610 uses a cascading inlet method to enter the anaerobic zone 120. The inlet of the anaerobic zone 120 is close to the outlet of the sludge return channel 131. The anaerobic zone 120 is equipped with several baffles, using baffle guidance technology to form granular activated sludge flocs. The anoxic zone 110 is connected to the bottom of the anaerobic zone 120. The anoxic zone 110 is equipped with several baffles, using baffle guidance technology to further disperse the activated sludge flocs. The sludge flocs form granular particles. The first compartment in the anoxic zone 110 is equipped with a nitrification liquid return outlet. Then, the water is pumped to the aerobic zone 130, which is connected to the uppermost layer of the anoxic zone 110. The aerobic zone 130 is equipped with an aeration mechanism 200 and an MBBR biofilm zone. The aerobic zone 130 can be equipped with modular biofilm modules installed in the aerobic zone to form an MBBR aerobic contact oxidation unit area module. Then, the wastewater is pumped to the sedimentation zone 140 for static sedimentation. The settled water is then transported to the membrane filtration zone 150 for filtration to obtain clean water.

[0042] Example 2

[0043] Based on Example 1, in order to fully clear the sediment inside the arc-shaped tube 331 and promote the discharge of material from the discharge tube 333.

[0044] like Figure 6 As shown, in this embodiment, the air-push mechanism 500 includes an air injection pipe 510 that is inserted and fixed to the sedimentation zone 140. One end of the air injection pipe 510 is connected and fixed to a limiting pipe 1 520 and a limiting pipe 2 530. The bottom ends of the limiting pipe 1 520 and the limiting pipe 2 530 are respectively inserted into the corresponding positions of the receiving hopper 320 near the arc-shaped pipe 331. The limiting pipe 1 520 is slidably inserted into the sealing block 1 340, and the limiting pipe 2 530 is slidably inserted into the sealing block 2 350.

[0045] Specifically, the shape of the sealing block is the same as the internal shape of the receiving hopper 320, which makes it easy for the sealing block to be fully inserted into the receiving hopper 320. The limiting tubes, including limiting tube one 520 and limiting tube two 530, enable the sealing block to move stably in the vertical direction, sealing the floating sealing block into the receiving hopper 320 on the other side of the V-shaped plate 310. Then, an external air pump is used to supply air to the air injection pipe 510. The airflow enters the receiving hopper 320 and the arc-shaped pipe 331 in the sealed state, which makes it easy to fully flush out the sedimentation zone 140 inside the arc-shaped pipe 331. At this time, the auger 332 can be rotated in the reverse direction to squeeze the sediment into the frustum-shaped cylinder, so that the water remaining in the sediment can flow away through the release pipe 330 first. Then, the auger 332 is rotated in the forward direction to concentrate and transport the sediment out.

[0046] In this invention, in order to achieve process modularization and equipment integration, the overall equipment process scheme is conceived and preliminarily designed, including anaerobic, anoxic, and aerobic process treatment zones:

[0047] (1) The first anaerobic zone is 120, in which raw sewage and phosphorus-containing sludge returned from the secondary sedimentation tank enter simultaneously. The main function of this tank is to release phosphorus, which increases the concentration of P in the sewage. Dissolved organic matter is absorbed by microbial cells, which reduces the concentration of BOD5 in the sewage. In addition, some of NH3-N is removed due to cell synthesis, which reduces the concentration of NH3-N in the sewage, but the NO3-N content does not change.

[0048] (2) In the anoxic zone 110, denitrifying bacteria use organic matter in the wastewater as a carbon source to reduce a large amount of NO3-N and NO2-N brought into the return mixed liquor to N2 and release it into the air. Therefore, the BOD5 concentration decreases, the NO3-N concentration decreases significantly, while the phosphorus concentration changes very little.

[0049] (3) In the aerobic zone, organic matter is biochemically degraded by microorganisms, and organic nitrogen continues to decrease. It is ammonified and then nitrified, which causes the NH3-N concentration to decrease significantly. However, as the nitrification process increases the NO3-N concentration, P also decreases at a relatively fast rate due to the excessive uptake by polyphosphate bacteria.

[0050] Equipment Room 170: Equipment Room 170 includes supporting equipment (inlet lift pump, aeration blower, air lift blower, product water pump, backwash pump, dosing system) and electrical control system. The supporting equipment is required for the process of treating rural domestic sewage with this product.

[0051] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0052] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
