[0016] Furthermore, the integrated high-efficiency anaerobic equipment provided by the present invention has at least the following beneficial effects compared with the prior art:

[0017] Multi-stage sewage treatment is achieved through the sequential separation of a primary septic tank, a secondary septic tank, a primary anaerobic tank, and a secondary anaerobic tank within the sewage treatment shell. This design not only improves sewage treatment efficiency but also ensures the stability and compliance of effluent quality. At each treatment stage, the sewage undergoes sedimentation, decomposition, and anaerobic biological treatment, effectively removing organic matter and other pollutants.

[0024] like Figure 1 As shown, the integrated high-efficiency anaerobic equipment of the present utility design includes a sewage treatment shell 1; the inner cavity of the sewage treatment shell 1 is sequentially separated into a first-level septic tank 1.1, a second-level septic tank 1.2, a first-level anaerobic tank 1.3 and a second-level anaerobic tank 1.4; a first-level connecting pipe 2 is provided between the first-level septic tank 1.1 and the second-level septic tank 1.2, a second-level connecting pipe 3 is provided between the second-level septic tank 1.2 and the first-level anaerobic tank 1.3, and a third-level connecting pipe 4 is provided between the first-level anaerobic tank 1.3 and the second-level anaerobic tank 1.4; the first-level anaerobic tank 1.3 and the second-level anaerobic tank 1.4 are both filled with biological filler floats 5.

[0025] The equipment is mainly composed of a sewage treatment shell 1, the interior of which is divided into four main functional areas in sequence: a primary septic tank 1.1, a secondary septic tank 1.2, a primary anaerobic tank 1.3 and a secondary anaerobic tank 1.4.

[0026] Primary sewage treatment in a septic tank 1.1:

[0027] The sewage first enters the primary septic tank 1.1, where it undergoes preliminary sedimentation and decomposition.

[0028] Sewage transition primary connecting pipe 2:

[0029] The sewage after preliminary treatment flows into the secondary septic tank 1.2 through the primary connecting pipe 2.

[0030] Further breakdown of secondary septic tank 1.2:

[0031] In the secondary septic tank 1.2, the sewage continues to undergo sedimentation and further decomposition of organic matter.

[0032] Entering the anaerobic treatment secondary connecting pipe 3:

[0033] The sewage treated in the secondary septic tank 1.2 enters the primary anaerobic tank 1.3 through the secondary connecting pipe 3.

[0034] Anaerobic treatment first stage primary anaerobic tank 1.3:

[0035] In the primary anaerobic tank 1.3, the sewage comes into contact with the anaerobic microorganisms on the biological filler float 5, undergoing anaerobic biological treatment to further decompose organic matter.

[0036] In-depth anaerobic treatment three-stage connecting pipe 4:

[0037] The sewage treated in the primary anaerobic tank 1.3 enters the secondary anaerobic tank 1.4 through the tertiary connecting pipe 4.

[0038] Anaerobic treatment second stage secondary anaerobic tank 1.4:

[0039] In the secondary anaerobic tank 1.4, the sewage comes into contact with the anaerobic microorganisms on the biological filler float 5 again and undergoes more in-depth anaerobic biological treatment until it reaches the discharge standard or meets the subsequent treatment requirements.

[0040] As an embodiment, the sewage treatment housing 1 is sequentially provided with a water inlet pipe 6 connected to the primary septic tank 1.1 and a water outlet pipe 7 connected to the secondary anaerobic tank 1.4.

[0045] Preferably, the three-dimensional filter filler 11 is a block-mounted special filter mesh, which provides a larger filtering area and a more detailed filtering effect, helps to remove finer suspended matter and impurities, and improves the water quality of the outlet water.

[0046] As an embodiment, the biological filler float 5 includes a hollow sphere and the biological filler filled in the hollow sphere.

[0047] Preferably, the biological filler is one or more of volcanic rock filler, bamboo charcoal filler, and natural material filler.

[0048] These fillers have the advantages of large surface area, high porosity, corrosion resistance, and good biological stability, which are conducive to the growth and reproduction of microorganisms.

[0049] As an embodiment, the sewage treatment shell 1 is also provided with several inspection ports 1.5 adapted to the primary septic tank 1.1, the secondary septic tank 1.2, the primary anaerobic tank 1.3 and the secondary anaerobic tank 1.4, so as to facilitate operators to enter each treatment unit for maintenance and inspection.
