Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and more specifically, to an integrated deep wastewater treatment device. Background Technology

[0002] While existing wastewater treatment technologies and equipment have achieved significant results in large-scale urban wastewater treatment, they often face challenges for small-scale facilities, especially in rural areas, livestock farms, and remote regions. These technologies often involve large footprints, complex equipment, difficult maintenance, and inconvenient transportation. To address these issues, the market has placed higher demands on equipment capable of meeting the needs of small-scale wastewater treatment. Integrated water treatment devices, as a type of integrated and modular wastewater treatment system, are gradually becoming an effective solution to this problem. These devices typically feature small footprints, compact structures, easy installation, and stable treatment results, making them particularly suitable for wastewater treatment needs in rural areas, livestock farms, and some remote regions. Their design integrates multiple wastewater treatment processes, such as physical filtration, chemical treatment, sedimentation, and aeration, enabling effective synergy among these processes and allowing for flexible adjustments to the treatment process based on the specific characteristics of the wastewater.

[0003] However, despite the many advantages of existing integrated water treatment systems, several technical challenges remain in practical applications. These include: how to effectively integrate various wastewater treatment processes within a limited space to improve treatment efficiency and stability; how to simplify equipment operation and maintenance procedures to reduce operating costs and technical barriers; and how to ensure that treated wastewater meets prescribed discharge standards and possesses a certain degree of environmental friendliness. These issues urgently need to be addressed.

[0004] Therefore, it is necessary to propose an integrated deep wastewater treatment device to at least partially solve the problems existing in the prior art. Summary of the Invention

[0052] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement it based on the description.

[0053] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0054] Example 1:

[0055] like Figures 1-3 As shown, the present invention provides an integrated wastewater deep treatment device, comprising:

[0056] The housing 1 contains a filter chamber 4, a sedimentation chamber 6, and a micro-aeration chamber 8 connected in sequence. The filter chamber 4 is connected to a wastewater inlet valve 3, and the micro-aeration chamber 8 is connected to a drain valve 10. The lower chamber of the filter chamber 4 is set up as a control center and a dosing chamber 2. The control center and dosing chamber 2 are equipped with a dosing tank and a water quality parameter monitoring instrument. A metering valve is installed on the dosing tank and connected to a dosing pipeline. The outlet of the dosing pipeline and the detection end of the water quality parameter monitoring instrument are located in the filter chamber 4, the sedimentation chamber 6, and the micro-aeration chamber 8.

[0057] The filtration chamber 4, sedimentation chamber 6, micro-aeration chamber 8, and control center and dosing chamber 2 are separated by partitions.

[0058] Multiple dosing tanks are provided to hold flocculants, phosphorus removal agents, and nitrogen removal agents; the water quality monitoring instruments can detect parameters including COD (chemical oxygen demand), TP (total phosphorus), TN (total nitrogen), SS (suspended solids), pH (acidity / alkalinity), and DO (dissolved oxygen).

[0059] A filter plate 5 is vertically installed inside the filter chamber 4. A groove 11 is provided on the side wall of the filter chamber 4 for inserting the filter plate 5. The filter plate 5 is a portable cuboid structure and is filled with activated carbon.

[0060] A drain valve 7 for discharging settled sludge is installed below the sedimentation chamber 6. The middle part is connected to the micro-aeration chamber 8 through a drainage pipe, and a drainage pump 12 is installed on the drainage pipe.

[0061] A ring-shaped aeration pipe 9 is laid at the bottom of the micro-aeration chamber 8 for aeration of the sewage.

[0062] Based on the above-mentioned integrated wastewater deep treatment device, the integrated water treatment device is designed in detail as follows for a treatment scale of 500t / d of aquaculture wastewater:

[0063] (1) Box 1: Based on the water volume to be treated and the residence time of each treatment unit, the dimensions of box 1 are designed to be 5m long, 2.8m wide and 3.3m high.

[0064] (2) Filter chamber 4: The effective volume of filter chamber 4 is 14m³. 3 The designed residence time is 2.5 hours. Filter plate 5 is a portable rectangular prism with dimensions of 3.2m long, 0.15m wide, and 1.5m high. It is filled with activated carbon at a density of 0.7m³ per filter plate. 3 The filter plate 5 is installed inside the filter chamber 4 via the groove 11, making it easy to replace and clean.

[0065] (3) Sedimentation chamber 6: The effective volume of sedimentation chamber 6 is 19m³. 3The designed residence time is 4 hours. A dosing pipe is installed on the inner wall of sedimentation chamber 6 to add flocculants and other chemicals to promote the sedimentation of suspended solids. Two drain valves 7 are installed below for periodically discharging the settled sludge. A drain pump 12 is installed in the middle of the left side to transport the settled water to the micro-aeration chamber 8.

[0066] (4) Micro-aeration chamber 8: The effective volume of micro-aeration chamber 8 is 14m³. 3 The designed residence time is 3 hours. A ring-shaped aeration pipe 9 is laid at the bottom of the micro-aeration chamber 8, and the aeration heads are microporous aeration heads, ensuring uniform aeration and high oxygen utilization. A drain valve 10 is connected to the lower left side for discharging the treated water.

[0067] The operating steps of the aquaculture wastewater treatment device are as follows:

[0068] (1) Water intake stage: Aquaculture wastewater enters filter chamber 4 through inlet valve 3. The inlet flow rate is reasonably controlled according to the treatment capacity of the device and the amount of aquaculture wastewater generated. During the water intake process, the control center monitors the inlet water quality parameters in real time to provide a basis for subsequent treatment.

[0069] (2) Filtration stage: Wastewater is filtered through filter plate 5 in filter chamber 4. The activated carbon filled in filter plate 5 adsorbs and retains suspended solids, organic matter and some heavy metal ions in the wastewater. As filtration proceeds, the filtration effect of filter plate 5 will gradually decrease. When the water quality monitoring instrument detects that the water quality of the effluent from filter chamber 4 does not meet the requirements, filter plate 5 needs to be replaced in time.

[0070] (3) Sedimentation stage: Filtered wastewater enters sedimentation chamber 6. The control center adds appropriate amounts of flocculants and other chemicals to the sedimentation chamber 6 through the chemical addition pipe, based on the influent water quality and the water quality within the chamber. The flocculants cause suspended solids in the wastewater to coagulate into larger particles, accelerating the sedimentation process. Two drain valves 7 at the bottom of sedimentation chamber 6 are opened periodically to discharge the settled sludge, ensuring the normal operation of sedimentation chamber 6.

[0071] (4) Micro-aeration stage: The supernatant after sedimentation is transported to the micro-aeration chamber 8 via the drainage pump 12. The annular aeration pipe 9 at the bottom of the micro-aeration chamber 8 aerates the wastewater, providing sufficient dissolved oxygen for the microorganisms. Under aerobic conditions, the microorganisms decompose and transform the organic matter in the wastewater, while removing pollutants such as nitrogen and phosphorus. The control center adjusts the aeration rate and reagent dosage in real time based on the water quality parameters in the micro-aeration chamber 8 to ensure optimal wastewater treatment results.

[0072] (5) Effluent stage: The wastewater, after micro-aeration treatment, is discharged through drain valve 10. During the effluent process, water quality monitoring instruments monitor the effluent quality in real time to ensure that the effluent quality meets the relevant national or local discharge standards. If the effluent quality does not meet the requirements, the control center will adjust the treatment parameters and further treat the wastewater.

[0073] The integrated water treatment device described above effectively removes pollutants such as organic matter, nitrogen, phosphorus, and suspended solids from aquaculture wastewater. Actual operation tests show that the treated effluent meets relevant national or local emission standards, with COD removal rates exceeding 80%, TP removal rates exceeding 90%, TN removal rates exceeding 70%, and SS removal rates exceeding 95%.

[0074] Example 2:

[0075] like Figures 4-8 As shown, based on the above embodiment 1, a flat premixed dosing tank 20 is installed in the control center and dosing room 2. The premixed dosing tank 20 includes:

[0076] The first mixing chamber 21 is located at the center of one side of the premixing dosing tank 20;

[0077] Baffles 23, multiple baffles 23 are spaced apart on both sides of the inner wall of the first mixing chamber 21;

[0078] Multiple drug inlet pipes are connected to multiple drug dosing tanks respectively, and are used to deliver drug solution to the first mixing chamber 21;

[0079] Two drug outlet pipes 22 are symmetrically arranged at the ends of the first mixing chamber 21 and connected to the drug dosing pipeline.

[0080] The working principle and beneficial effects of the above technical solution are as follows:

[0081] A premixed dosing tank 20 is installed in the control center and dosing room 2. The dosing tank delivers the liquid medicine to the first mixing chamber 21 through the inlet pipe. Multiple dosing tanks are used to hold different types of liquid medicine. The various liquid medicines are mixed in the first mixing chamber 21. When the liquid medicine flows in the first mixing chamber 21, the flow direction is frequently changed under the guidance of the baffle 23, which prolongs the residence time of the liquid medicine in the first mixing chamber 21 and improves the mixing effect. The mixed liquid medicine flows out through the outlet pipe 22. The premixed dosing tank 20 is designed with a flat structure and is placed horizontally. It can fully mix the liquid medicine during the flow process before discharge. Compared with the existing stirred tank structure, it can prevent the liquid medicine from flowing out of the tank without being fully mixed under the action of gravity, which can effectively improve the premixing efficiency of the liquid medicine. Since the separate stirred tank is eliminated, the liquid medicine does not need to be completely fed into the stirred tank for mixing, which shortens the residence time in the premixing stage and thus shortens the dosing delay time.

[0082] Example 3:

[0083] Based on the above embodiment 2, a defoaming rod 24 is provided at the center of the end of the first mixing chamber 21, and each baffle 23 has a different length to form a curved flow channel. Spikes for piercing the bubbles in the mixture are evenly arranged on the baffle 23 and the defoaming rod 24.

[0084] The working principle and beneficial effects of the above technical solution are as follows:

[0085] The baffles 23 have varying lengths, further enhancing the dispersion and mixing effect of the liquid. Due to chemical reactions or collisions, bubbles are generated in the mixed liquid. These bubbles are punctured by the spikes on the baffles 23 and the defoaming rod 24, reducing the bubble content in the mixture. This ensures stable pressure after the liquid enters the dosing pipeline, guaranteeing a stable dosing process and preventing bubbles from affecting the accuracy of dosing control.

[0086] Example 4:

[0087] Based on the above embodiment 2, the premixed dosing tank 20 also includes:

[0088] The second mixing chamber 41 is located on the other side of the premixing dosing tank 20. The liquid medicine in multiple dosing pipes is collected in the second mixing chamber 41, and a stirring mechanism is provided in the second mixing chamber 41.

[0089] A connecting pipe 42 is located at the center of the premixing dosing tank 20. One end of the connecting pipe 42 is connected to the first mixing chamber 21, and the middle part is connected to the second mixing chamber 41 through the through groove 43. The other end of the connecting pipe 42 extends out of the premixing dosing tank 20 and is connected to the pump body for injecting water into the first mixing chamber 21 and the second mixing chamber 41.

[0090] The working principle and beneficial effects of the above technical solution are as follows:

[0091] The premixed dosing tank 20 is equipped with a second mixing chamber 41. Multiple inlet pipes supply the chemical solutions into the second mixing chamber 41, where a stirring mechanism mixes the solutions. The mixed solution then flows through a channel 43 into a connecting pipe 42, and is subsequently transported to the first mixing chamber 21 for secondary mixing and defoaming. The stirring mechanism in the second mixing chamber 41 increases the fluidity of the chemical solution, improves the mixing effect, and enhances the reaction efficiency between the chemical solution and the wastewater.

[0092] One end of the connecting pipe 42 is connected to the pump body. On the one hand, the pump body replenishes clean water into the first mixing chamber 21, which helps dissolve the particles in the solution and makes it easier to adjust the mixed solution to the preset concentration to adapt to different wastewater qualities. On the other hand, when maintenance is carried out, clean water is pumped into the connecting pipe 42 through the pump body. The clean water enters the first mixing chamber 21 and the second mixing chamber 41 and flows back into the inlet pipe to achieve backwashing and cleaning of the premixed dosing tank 20, reducing the internal solution residue and attachment, preventing blockage and ensuring the accuracy of subsequent solution mixing.

[0093] Example 5:

[0094] Based on the above embodiment 4, the premixing dosing tank 20 also includes a premixing treatment unit, which includes:

[0095] The first pretreatment chamber 25, two first pretreatment chambers 25 are symmetrically arranged on both sides of the first mixing chamber 21. One end of the first pretreatment chamber 25 is connected to the first drug inlet tube 29, and the other end is open and connected to the second mixing chamber 41.

[0096] A rotating shaft 26 is rotatably disposed inside the first pretreatment chamber 25. The axis of the rotating shaft 26 is aligned with the drug feeding direction. A first vertical plate 27 supporting the rotating shaft 26 is disposed inside the first pretreatment chamber 25.

[0097] A stirring plate assembly, with multiple stirring plate assemblies connected to a rotating shaft 26, each stirring plate assembly includes multiple stirring plates 28 arranged circumferentially, and the stirring plates 28 in adjacent stirring plate assemblies are staggered. The liquid medicine impacts the stirring plate assembly, driving the rotating shaft 26 to rotate.

[0098] The working principle and beneficial effects of the above technical solution are as follows:

[0099] A premixing treatment unit is installed inside the premixing dosing tank 20. This unit is used to treat solutions with poor or low solubility, such as polyacrylamide solutions. A first pretreatment chamber 25 is connected to a first inlet pipe 29, which in turn is connected to a dosing tank containing the solution. The solution flows into the first pretreatment chamber 25 under the power of a pump. The flow impact and pressure of the solution drive the stirring plate assembly to rotate, which in turn drives the rotating shaft 26 to rotate. The stirring plates 28 are arranged in a staggered pattern on the stirring plate assembly, allowing for frequent changes in the flow direction of the solution and improving its fluidity. Under the stirring action, suspended particles in the solution are effectively mixed into the solution. This pretreatment process addresses the poor or low solubility of the solution by agitating it before mixing it with other solutions, preventing the precipitation of particles during the flow process, which could affect the final solution ratio and cause structural blockage.

[0100] Example 6:

[0101] Based on the above embodiment 5, the premixing unit further includes:

[0102] The first magnetic block 31 is connected to the outer end face of the stirring plate 28;

[0103] Water replenishment airbags 32 are connected to the side wall of the first pretreatment chamber 25 and correspond one-to-one with multiple stirring plate groups. The water inlet of the water replenishment airbag 32 is connected to the water supply pipeline. Multiple water outlets are provided on the upper and lower sides of the water replenishment airbag 32, and spray pipes 33 are connected to the water outlets.

[0104] The second magnetic block 34 is connected to the side of the water replenishment airbag 32 near the rotating shaft 26, and the second magnetic block 34 has the same magnetism as the first magnetic block 31.

[0105] The working principle and beneficial effects of the above technical solution are as follows:

[0106] When the premixing unit is in use, the rotating shaft 26 drives the stirring plate 28 to rotate synchronously, and the first magnetic block 31 on the stirring plate 28 rotates accordingly. As the first magnetic block 31 approaches the second magnetic block 34, it generates a repulsive force on it. The first magnetic block 31 pushes the second magnetic block 34 to move and squeezes the water replenishment airbag 32. The clean water in the water replenishment airbag 32 flows out from the outlet and is replenished into the first pretreatment chamber 25 through the spray pipe 33. When the first magnetic block 31 moves away from the second magnetic block 34, the water replenishment airbag 32 gradually returns to its original position under its own elastic force. Water in the water supply pipeline enters the water replenishment airbag 32 through the one-way water inlet valve to replenish it.

[0107] Through the above structural design, during the drug solution introduction process, water is replenished into the first pretreatment chamber 25 through the cyclic compression and expansion of the water replenishment airbag 32. This ensures that the drug solution can come into sufficient contact with water during stirring, improving the dissolution rate. Simultaneously, it prevents suspended particles from being thrown out by the stirring plate 28 and adhering to the surface, thus avoiding undissolved particles. The nozzle 33 can be bent towards one side of the stirring plate 28, simultaneously rinsing the stirring plate 28 during the water replenishment process, reducing drug adhesion and ensuring the drug dissolution rate in the solution.

[0108] Example 7:

[0109] Based on the above embodiment 5, the stirring mechanism includes:

[0110] Pulley 44 is connected to the end of rotating shaft 26, and the pulleys 44 on the two rotating shafts 26 are connected by a synchronous belt 45. The synchronous belt 45 has transmission teeth evenly arranged on its inner side.

[0111] Gear 46, the shaft of gear 46 is rotatably connected to the second vertical plate 47 inside the second mixing chamber 41, and gear 46 is meshed with the transmission gear;

[0112] A stirring impeller 48 is connected to the shaft of gear 46 and is used to stir the mixture in the second mixing chamber 41.

[0113] The working principle and beneficial effects of the above technical solution are as follows:

[0114] When the rotating shaft 26 rotates, it drives the pulleys 44 to rotate in the same direction. The synchronous belts 45 wound on the two pulleys 44 rotate accordingly. The transmission teeth on the inner side of the synchronous belts 45 mesh with the gears 46, driving the two gears 46 to rotate synchronously. The shaft of the gears 46 drives the stirring impeller 48 to rotate, thus stirring the mixture in the second mixing chamber 41. Through the above structural design, the stirring mechanism and the rotating shaft 26 are linked and driven by the power of the liquid medicine, so that the stirring process and the drug feeding process are synchronized. In addition, sufficient power can be ensured by adjusting the power of the pump body on the dosing tank, or a motor can be installed at the first vertical plate 27 to compensate for the power. Protective shells can be installed on the outside of the pulleys 44, synchronous belts 45 and gears 46 of the stirring mechanism, and the protective shells should avoid the communication ports to prevent the mixture from entering the stirring mechanism and affecting the transmission.

[0115] Example 8:

[0116] Based on the above embodiment 4, the premixed dosing tank 20 also includes a preheating treatment unit, which includes:

[0117] The preheating pipe 35 is installed on the support sleeve on the outer wall of the premixing dosing tank 20. The preheating pipe 35 forms a second pretreatment chamber 36 inside. The preheating pipe 35 has an electric heating wire heating layer on its pipe wall. The electric heating wire heating layer is electrically connected to the control center. One end of the preheating pipe 35 is connected to the second drug inlet pipe 37 and arranged close to the first drug inlet pipe 29. The other end of the preheating pipe 35 is connected to the second mixing chamber 41 through the bend pipe 38.

[0118] The filter box 39 is located on the inner wall of the second mixing chamber 41 and is used to filter out particulate matter in the liquid medicine introduced by the bend tube 38. The side wall of the filter box 39 away from the bend tube 38 is uniformly provided with filter holes.

[0119] The working principle and beneficial effects of the above technical solution are as follows:

[0120] A preheating unit is installed on the premixed dosing tank 20. This unit is used to treat solutions whose solubility is greatly affected by temperature, such as polyaluminum chloride solution. The preheating pipe 35 is connected to the second inlet pipe 37, which is connected to a dosing tank containing the temperature-sensitive solution. The solution flows into the second pretreatment chamber 36 under the power of a pump. An ambient temperature sensor detects the ambient temperature. When the temperature is lower than a preset temperature in winter, the heating element is energized, raising the overall temperature of the preheating pipe 35 and the second pretreatment chamber 36. This heat is transferred to the solution, ensuring complete dissolution of the drug without the precipitation of particulate matter. A filter box 39 filters out any precipitated particulate matter. As the solution heats up, it comes into full contact with the particulate matter as it passes through the filter box 39, causing the particulate matter to redissolve in the heated solution and enter the second mixing chamber 41.

[0121] Through the above structural design, the solubility of the drug solution is greatly affected by temperature. In view of the solubility characteristics of such drug solutions, the drug solution itself is preheated before being mixed with other drug solutions to prevent the precipitation of particulate matter due to low temperature during the flow of the drug solution, which would affect the final ratio of the drug solution and cause structural blockage.

[0122] During use, the premixed dosing tank 20 appropriately stirs or preheats the solutions in each dosing tank according to their different solubility characteristics. This solves the problem of particulate matter precipitation caused by prolonged storage or low-temperature environments, which leads to inaccurate solution ratios. The premixed dosing tank 20 ensures the solutions are in a good dissolved state before mixing, thereby guaranteeing sufficient reaction and effective wastewater treatment. Connected to the inlet pipe, the premixed dosing tank 20 requires no modification to the dosing tanks, simplifying installation and reducing costs. Furthermore, its flat design minimizes space requirements, making it ideal for small-scale wastewater treatment plants with limited space.
