DETAILED DESCRIPTION

[0020] The present invention will be further described in detail below with reference to specific embodiments:

[0021] like Figure 1 , Figure 2 and Figure 4 As shown, a wastewater purification device includes a housing 1, with an inlet pipe 11 and an outlet pipe 12 fixed at both ends of the housing 1. The interior of the housing 1 is hollow, and wastewater enters the housing 1 through the inlet pipe 11 and flows sequentially through a buffer zone 3, anoxic zone 4, aerobic zone 5, and sedimentation zone 6 set within the housing 1. A pair of mounting plates 7 are fixed vertically inside the housing 1; one mounting plate 7 is configured as the boundary between the buffer zone 3 and the anoxic zone 4, and the other mounting plate 7 is configured as the boundary between the anoxic zone 4 and the aerobic zone 5.

[0022] Buffer zone 3 is mainly used for wastewater collection and preliminary sedimentation of large particulate impurities in the wastewater. A first guide channel 31 is provided within buffer zone 3. The first guide channel 31 is vertically oriented, with its length set at half the depth of buffer zone 3. The bottom end of the first guide channel 31 is located in the middle of buffer zone 3, allowing solid matter in the wastewater to settle at the bottom of buffer zone 3, while the top end is flush with the top of buffer zone 3. After wastewater flows into tank 1 from inlet pipe 11, it enters from the bottom end of the first guide channel 31 and then enters the anoxic zone 4 from the top end of the first guide channel 31.

[0023] The anoxic zone 4 is used for hydrolysis reactions. Through the denitrification process, the pH value of the wastewater is increased, and a portion of the BOD (biochemical oxygen demand) is removed in conjunction with nitrification. The anoxic zone 4 includes a second guide channel 41 and a first packing plate 42. The second guide channel 41 is vertically positioned, with its top corresponding to the first guide channel 31. Wastewater flowing out of the first guide channel 31 then enters the second guide channel 41. The first packing plate 42 is horizontally fixed to the mounting platform 71 on the mounting plate 7, and first packing material is attached to it. The bottom end of the second guide channel 41 extends into the bottom of the anoxic zone 4, and the first packing plate 42 is positioned higher than the first guide channel 31, allowing wastewater discharged from the second guide channel 41 to pass through the bottom end of the first packing plate 42, thus enabling the first packing material to treat the wastewater with anoxic conditions.

[0024] The sewage from the top end of the anoxic zone 4 flows into the aerobic zone 5, and the aerobic zone 5 uses the metabolic activity of aerobic microorganisms to decompose the organic matter in the sewage into inorganic matter, thereby achieving the purpose of purifying the water quality. The third flow guide groove 51 and the second filler plate 52 are included. The sewage flows into the third flow guide groove 51 from the anoxic zone 4, and the third flow guide groove 51 has a length close to that of the second flow guide groove 41. The second filler plate 52 is fixed along the horizontal direction with the mounting plate 7 and is loaded with the second filler. The second filler plate 52 is higher than the bottom end of the third flow guide groove 51, so that the sewage in the third flow guide groove 51 penetrates from the bottom of the first filler plate 42, thereby allowing the second filler to perform aerobic treatment on the sewage.

[0025] The bottom end of the second flow guide groove 41 and the third flow guide groove 51 is lower than the corresponding first filler plate 42 and second filler plate 52, which allows the sewage to flow downward in the second flow guide groove 41 and the third flow guide groove 51, and then effectively drives the dead water in the corner through the first filler plate 42, eliminating the dead zone and improving the treatment efficiency.

[0026] As shown in Figure 3 The sedimentation zone 6 is arranged in the aerobic zone 5 and is used for removing the solid suspended matter that can be precipitated in the sewage. The sedimentation zone 6 includes the first sedimentation groove 61, the second sedimentation groove 62, and the sedimentation partition plate 63. The first sedimentation groove 61 is fixed on the third flow guide groove 51 and has a common side wall with the third flow guide groove 51. The sedimentation partition plate 63 is arranged along the vertical direction and has a top end flush with the top ends of the first sedimentation groove 61 and the second sedimentation groove 62 and a bottom end located at the middle of the first sedimentation groove 61 and the second sedimentation groove 62, so that the lower part of the first sedimentation groove 61 is in communication with the second sedimentation groove 62. The first sedimentation groove 61 is provided with the overflow weir 64 in communication with the aerobic zone 5 at both ends, and the overflow weir 64 is arranged in a zigzag structure. The sewage in the aerobic zone 5 enters the first sedimentation groove 61 from the overflow weir 64. In addition, during the process of the sewage entering the second sedimentation groove 62 from the lower part of the first sedimentation groove 61, the impurities floating on the surface of the sewage are blocked in the first sedimentation groove 61 by the sedimentation partition plate 63.

[0027] The above examples are only for illustrating the technical concept and characteristics of the present application, and the purpose is to enable those skilled in the art to understand the content of the present application and implement it, and cannot limit the protection scope of the present application. For those skilled in the art, it is obvious that the present application is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present application. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and therefore all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application.
