[0028] Compared with the prior art, the advantages of the present invention are:

[0029] (1) In the present invention, the filtration zone, multifunctional reaction zone, aerobic zone and sedimentation zone are arranged in a three-dimensional manner in the horizontal and vertical directions within the box body, and the various treatment zones are arranged compactly, which greatly reduces the footprint of the micro sewage treatment equipment and is more suitable for individual household sewage treatment.

[0030] (2) The present invention is provided with a multifunctional reaction zone, in which a detection unit and a control unit are provided. The working mode of the multifunctional reaction zone is intelligently adjusted based on the detection results of the chemical oxygen demand in the sewage by the detection unit. For sewage with high chemical oxygen demand, the removal of ammonia nitrogen in the sewage is further enhanced to ensure the stable removal of color and odor. For sewage with low chemical oxygen demand, the macromolecular organic matter in the sewage that is difficult to degrade is hydrolyzed into small molecules, which facilitates the biochemical reaction in the subsequent aerobic stage. As a result, the best treatment effect can be achieved for sewage with different chemical oxygen demand.

[0031] (3) Considering that it is difficult for individual users to perform regular maintenance of the present invention, which may lead to the detection unit being prone to failure or inaccurate detection, a preset mode 2 is set to automatically adjust the multifunctional treatment area to the hydrolysis and acidification function during the peak water usage period of the day, which is more convenient for users to use.

[0032] (4) The filler mechanism is set as a pendulum structure. Compared with the fixed filler mechanism in the existing technology, the pendulum structure swings with the water flow under the action of the aeration tube, strengthening the contact with the sewage and reducing the filler filling ratio. At the same time, it can diffuse the bubbles generated by the aeration tube to a wider range, thereby increasing the service area of ​​the aeration tube.

[0033] (5) The housing is configured as a double-layer structure comprising an inner shell and an outer shell, which provides a certain degree of thermal insulation for the sewage and bacterial flora inside, thereby facilitating the effective conduct of internal biochemical reactions. In addition, the water inlet and drainage pipes are both buried in the groove structure and protected by a high-strength protective portion, and the water inlet and drainage ports are provided on a fixed portion integrally formed with the base. This makes it difficult for the pipes to be damaged when subjected to external impacts such as livestock, thereby preventing sewage leakage.

[0034] In addition, the groove is set in a rectangular shape, and the back can be used as the installation surface of the filter basket and the sedimentation mechanism, further improving the compactness of the overall equipment.

[0035] (6) The bottom end of the sedimentation mechanism is inclined, and a collecting tank is provided at the bottom end of the first sedimentation tank. The sludge is collected in the collecting tank under the action of gravity instead of being dispersed throughout the first sedimentation tank, which facilitates the recovery and discharge of the sludge.

[0045] The present invention is further described in detail below with reference to specific embodiments:

[0046] As shown in FIG1 , an integrated sewage treatment machine includes a housing 1 , in which a plurality of treatment zones are arranged in a three-dimensional manner, including a filtration zone, a biochemical reaction zone, and a sedimentation zone arranged in sequence along the flow direction of the sewage.

[0047] As shown in Figure 2, the bottom of the housing 1 serves as a base, and the sidewalls are designed as a double-layer structure, including an outer shell 11 disposed on the outside, and an inner shell 12 fixed to the outer shell 11. The sewage and corresponding treatment equipment are all housed within the inner shell 12. The outer shell 11 is connected to an upper cover 13. When the upper cover 13 is closed, the interior of the housing 1 forms a sealed space. Furthermore, a hollow chamber is formed between the outer shell 11 and the inner shell 12, providing thermal insulation.

[0048] In this embodiment, the outer shell comprises a protective portion 111 and a fixed portion 112. The protective portion 111, which occupies the majority of the outer shell, is made of high-strength engineering plastic and is connected to the base and inner shell 12 via snap fasteners. Two fixed portions 112 are provided and integrally molded with the base. One fixed portion 112 has a horizontally defined water inlet, and the other has a horizontally defined water outlet. Multiple grooves 14 are defined on the outer wall of the inner shell 12. The horizontal cross-section of each groove 14 is rectangular. The water inlet and water outlet pipes, which connect the water inlet and water outlet, are embedded in the corresponding grooves 14.

[0049] As shown in Figures 3 and 4, the filtration area is used to intercept larger debris in the sewage. A filter basket 2 is located within the filtration area. This basket is connected to the water inlet pipe that runs through the groove 14 and is fixed to the back of the groove 14. This basket performs preliminary filtration of the sewage. The basket 2 includes a water storage area 21 for storing sewage. The sidewalls of the water storage area 21 are contoured to the inner shell 12, and a circular filter hole 22 is vertically defined at the bottom end for overflow. A removable filter screen is installed horizontally at the filter hole 22.

[0050] As shown in Figure 3, the biochemical reaction zone is used to perform biochemical reactions on wastewater, regulating its pH and the composition and content of its compounds. The biochemical reaction zone consists of two independently arranged sections: a multifunctional reaction zone 3 and an aerobic zone 4. The multifunctional reaction zone 3 is located below the filtration zone, with its top boundary being the bottom surface of the filter basket. The aerobic zone 4 is horizontally adjacent to the multifunctional reaction zone 3, bounded by the sidewalls of the multifunctional reaction zone 3, the inner shell 12, and the bottom of the sedimentation zone. Sewage enters the multifunctional reaction zone 3 and the aerobic zone 4 sequentially from the filtration zone. The aerobic zone 4 is equipped with a packing mechanism 5 and an aeration tube 6. The outlet end of the aeration tube 6 is located at the bottom of the inner shell 12 to provide oxygen to the packing mechanism 5. As shown in Figures 5 and 6, a packing rack is located above the aeration tube 6 to attach a packing composed of various aerobic microorganisms. The packing rack adopts a pendulum-type structure, including a first packing rack 51 arranged vertically and a second packing rack 52 arranged horizontally. Among them, the two ends of the first filling rack 51 are detachably fixed to the top frame 53 and the bottom frame 54 respectively. The top frame 53 is fixed to the inner shell 12. The bottom frame 54 is larger than the top frame 53 and is suspended in the inner shell 12 under the traction of the first filling rack 51. The two ends of the second filling rack 52 are detachably fixed to the top frame 53 and the bottom frame 54. Such an arrangement facilitates the installation and disassembly of the filling rack and the subsequent operation and maintenance replacement. In addition, the suspended bottom frame 54 can swing in a small range with the flow of sewage, thereby driving the filling rack to shake, expanding the contact range with the water flow, and then reducing the filling ratio of the filler to reduce costs. At the same time, with the movement of the filling rack and the bottom frame 54, the bubbles generated by the aeration pipe 6 can be diffused to a larger range, thereby increasing the service area of ​​the aeration pipe 6.

[0051] The multifunctional reaction zone 3 is provided with a packing mechanism 5 and an aeration pipe 6 having the same structure as the aerobic zone 4. The difference is that the packing in the multifunctional reaction zone 3 is set as facultative bacteria, which can produce different biochemical reactions with sewage in an oxygen-rich environment and an oxygen-deficient environment respectively. In addition, a detection unit and a control unit are also provided in the multifunctional reaction zone 3. The control unit includes an electric control cabinet 31 and a regulating valve 32, wherein the electric control cabinet 31 is arranged in a chamber between the inner shell 12 and the outer shell 11, and is electrically connected to the upper cover plate 13 and the regulating valve 32. The regulating valve 32 is arranged on the aeration pipe 6 in the multifunctional reaction zone 3. The detection unit includes three chemical oxygen demand detectors evenly arranged at the bottom end of the multifunctional reaction zone 3. There are two sewage treatment modes preset in the control unit.

[0052] Among them, mode 1 is: three chemical oxygen demand detectors detect the chemical oxygen demand in the multifunctional reaction area 3, and transmit multiple groups of detection results to the control unit, and the control unit performs outlier processing on the received detection data and compares it with the preset value.

[0053] When the average value of the treated test data is lower than 350 mg / L, the electric control cabinet 31 controls the regulating valve 32 to open, and the aeration volume of the aeration pipe 6 increases, so that the oxygen content in the multifunctional reaction zone 3 increases, and the facultative bacteria enter the aerobic state and perform aerobic treatment, further strengthening the removal of ammonia nitrogen in the sewage, ensuring the stable removal of color and odor, and maximizing the harmless treatment of the sewage to provide nitrogen, phosphorus and other nutrients for crops.

[0054] When the average value of the treated test data is higher than or equal to 350 mg / L, the electric control cabinet 31 controls the regulating valve 32 to close, and the aeration volume of the aeration pipe 6 is reduced, so that the oxygen content in the multifunctional reaction zone 3 is reduced, and the facultative bacteria enter an anoxic state, performing the hydrolysis and acidification function, and hydrolyzing the difficult-to-degrade large molecular organic matter in the sewage into small molecules, which is convenient for the biochemical reaction in the subsequent aerobic section.

[0055] Mode 2: The user presets specific time periods for peak water usage, such as morning, noon, evening, or night, on the upper cover 13, for example, 7:00-9:00 AM, 11:00 AM-1:00 PM, and 6:00-10:00 PM. When the user-preset time period arrives, the control unit controls the regulating valve 32 to close, allowing the multifunctional reaction zone 3 to enter the hydrolysis and acidification function. Conversely, outside the preset time period, the control unit controls the regulating valve 32 to open, allowing the multifunctional reaction zone 3 to perform aerobic treatment.

[0056] As shown in Figures 3 and 7, after being treated in the biochemical reaction zone, the sewage enters the sedimentation zone. The sedimentation zone is arranged at the top of the inner shell 12, above the aerobic zone 4 and at the same height as the filtration zone. A sedimentation mechanism 7 is provided in the sedimentation tank. The side wall of the sedimentation mechanism 7 is arranged in the same shape as the inner shell 12, and is connected to the drainage pipe that passes through the groove 14, and is fixed to the back of the groove 14 in close contact with the groove 14. The bottom of the sedimentation mechanism 7 serves as the top boundary of the aerobic zone 4, and the bottom of the sedimentation mechanism 7 is arranged at an angle to facilitate the deposition of solid particles. In this embodiment, three through holes are opened on one side of the sedimentation mechanism 7 for sewage to flow in. The sedimentation mechanism 7 is divided into a first sedimentation tank 71, a second sedimentation tank 72 and a third sedimentation tank 73 in sequence by partitions along the flow direction of sewage. The partitions include a first partition separating the first sedimentation tank 71 and the second sedimentation tank 72, and a second partition separating the second sedimentation tank 72 and the third sedimentation tank 73.

[0057] After a period of time, the sewage enters the first sedimentation tank 71 and separates into an upper layer of clear liquid and a lower layer of turbid liquid. A collection tank 74 is integrally fixed to the bottom of the first sedimentation tank 71. The bottom of the collection tank 74 is arranged horizontally, and the cross-section along the vertical direction forms a right-angled triangle structure. Combined with the inclined structure at the bottom of the first sedimentation tank 71, the sludge precipitated in the lower layer of turbid liquid is concentrated in the collection tank 74 under the action of gravity. A sludge discharge pipeline is also provided at the corresponding position of the collection tank 74 to facilitate the removal or recovery of the sludge. A rectangular overflow weir 77 is provided at the end of the first partition away from the collection tank 74. Under the action of laminar flow, the upper layer of clear liquid flows from the first sedimentation tank 71 through the rectangular overflow weir 77 into the second sedimentation tank 72. A drug delivery mechanism 75 is provided at the top of the second sedimentation tank 72. A slow-release chlorine tank is installed inside the drug delivery mechanism 75 to sterilize and disinfect the upper layer of clear liquid to ensure the residual chlorine index of the drainage. In addition, a particle adsorption mechanism is connected to the second sedimentation tank 72 perpendicular to the flow direction of the supernatant liquid through the adsorption mechanism fixing frame 76. After the supernatant liquid flows through the particle adsorption mechanism, the insoluble inorganic matter, organic matter, silt, clay, microorganisms and other solid substances in the supernatant liquid are further adsorbed and filtered out.

[0058] A triangular weir 78 is provided on the second partition plate. The supernatant flows from the second sedimentation tank 72 through the weir 78 into the third sedimentation tank 73. A liquid level sensor is provided on the weir 78. The sensor detects the water level passing through the weir 78 in real time and transmits this information to the electrical control cabinet 31. This sensor controls the flow of sewage into the sedimentation mechanism 7, thereby achieving a stable laminar flow rate and ensuring a good sedimentation effect.
