[0039] In the following, only certain exemplary embodiments are simply described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present application. Therefore, the drawings and the description are considered to be essentially exemplary rather than limiting.

[0040] Figures 1-3 A structure diagram of an anaerobic device 100 according to an embodiment of the present application is shown. As shown in the figure, the anaerobic device 100 can include: Figures 1-3

[0041] Shell 110, the shell 110 has water inlet tank 116 on both sides, and the shell 110 has opening 117 on the top;

[0042] Partition 120, the partition 120 is arranged in the shell 110, and the partition 120 corresponds to one end inside the shell 110 with the water inlet tank 116;

[0043] Three-phase separator 130, the three-phase separator 130 is located at the bottom of the shell 110, the partition 120 corresponds to the three-phase separator 130, the opening 117 is located above the three-phase separator 130, and the sewage is separated by the three-phase separator 130 and then enters the shell 110 by the water inlet tank 116.

[0044] ​In the embodiment, the sewage is separated by the three-phase separator 130, then enters the shell 110 through the water inlet groove 116, and the sludge in the sewage is preliminarily adsorbed by the water inlet groove 116. The adsorbed sewage enters the three-phase separator 130 under the guidance of the partition plate 120, and the three-phase separator 130 separates the sewage into water and gas, while the sludge impurities in the sewage are deposited at the bottom of the shell 110. The gas generated after the separation of the three-phase separator 130 is transported outside the shell 110, and the water generated is transported to the opening 117 through the shell 110.

[0045] By arranging the three-phase separator 130 at the bottom of the shell 110, the gas- containing sludge-water mixture is preliminarily separated into gas and sludge-water mixture when the sewage rises in the anaerobic tank 200 and passes through the three-phase separator 130. The preliminarily separated sludge-water mixture enters the shell through the water inlet groove 116, so that the sludge in the sewage is deposited in the water inlet groove 116. The water and gas are separated by the three-phase separator 130 at the bottom of the shell 110. The water inlet of the water inlet groove 116 is guided by the partition plate 120 to avoid backflow of the water separated by the three-phase separator 130. Furthermore, the water inlet groove 116 is arranged on the shell 110 to further save the space required for sewage reaction.

[0046] As shown in Figure 1 , in an embodiment,

[0047] The partition plate 120 and the shell 110 form an included angle of 30°.

[0048] In the embodiment, the top of the three-phase separator 130 forms an included angle of 60°, and the partition plate 120 and the shell 110 form an included angle of 30° (i.e. the included angle between one end of the water inlet groove 116 in the shell 110 and the partition plate 120 is 60°). After the sewage in the water inlet groove 116 enters the shell 110, the partition plate 120 plays a certain guiding role, thereby improving the reaction efficiency of the three-phase separator 130 on the sewage.

[0049] As shown in Figures 1-3 , in an embodiment, the application further comprises:

[0050] The outer inclined plate 111 is arranged in the water inlet groove 116.

[0051] In the embodiment, the sludge in the sewage entering through the water inlet groove 116 is attached to the outer inclined plate 111 and preliminarily deposited, thereby creating good conditions for the re-deposition of the inner inclined plate 112. In addition, the inclination angle and spacing of the outer inclined plate 111 can be adjusted as needed to maximize the deposition area and deposition efficiency.

[0052] As shown inFigures 1-3 As shown in one embodiment, further comprising:

[0053] The inner inclined plate 112 is arranged in the shell, and is located above the three-phase separator 130.

[0054] In the embodiment, the organic matter remaining in the water separated by the outer inclined plate 111 is attached by the inner inclined plate 112, so that the harmful substances are removed, and the three-phase separator 130 and the outer inclined plate 111 attach the organic matter remaining in the separated water, thereby improving the efficiency of anaerobic treatment of sewage and reducing the loss of anaerobic sludge.

[0055] As shown in one embodiment, further comprising: Figures 1-3

[0056] The water collecting tank 113 is arranged in the shell 110 and is located above the inner inclined plate 112.

[0057] In the embodiment, the cross section of the water collecting tank 113 is in a “concave” shape structure, and the water separated by the three-phase separator 130 and adsorbed by the inner inclined plate 112 enters the water collecting tank 113.

[0058] As shown in one embodiment, further comprising: Figures 1-3

[0059] The water outlet pipe 114 penetrates the side wall of the shell 110 and is in communication with the water collecting tank 113.

[0060] In the embodiment, the water outlet pipe 114 is in communication with the water collecting tank 113, so that the water reacted in the three-phase separator 130 is taken out for next anaerobic or aerobic treatment.

[0061] As shown in one embodiment, further comprising: Figures 1-3

[0062] The exhaust pipe 115 penetrates the side wall of the shell 110 and is connected with the three-phase separator 130.

[0063] In the embodiment, the exhaust pipe 115 is connected with the three-phase separator 130, so that the gas generated after the sewage is separated by the three-phase separator 130 is discharged.

[0064] As shown in one embodiment, further comprising: Figure 1

[0065] The water collecting tank 113 is located at the opening 117, and the height of the water collecting tank 113 is lower than the height of the opening 117.

[0066] ​​​​In this embodiment, the height of the sump 113 is lower than the opening 117 to prevent the water processed by the three-phase separator 130 from overflowing from the opening 117 , thereby facilitating the collection of the water processed by the three-phase separator 130 through the sump 113 .

After sewage enters the bottom of the housing 201, an anaerobic reaction begins at the bottom of the housing 201, generating sludge and bubbles. The bubbles float upward and enter the bottom of the three-phase separator 130. After separation by the three-phase separator 130, the bubbles are discharged through the exhaust pipe 115 on the three-phase separator 130.

[0072] The sewage after the anaerobic reaction carries sludge and a small amount of gas, enters the shell 110 through the water inlet tank 116, adsorbs the sludge in the sewage through the outer inclined plate 111, and then adsorbs it through the inner inclined plate 112. The adsorbed sewage enters the water collection tank 113 and is finally discharged through the outlet pipe 114. The sludge on the outer inclined plate 111 and the inner inclined plate 112 is finally settled to the bottom of the outer shell 201 through the bottom of the shell 110.

[0073] Furthermore, the cross section of the three-phase separator 130 is arranged in an inverted V shape;

[0074] Furthermore, the liquid level of the sewage in the housing 201 is higher than the height of the water inlet groove 116 and lower than the height of the opening 117 on the housing 110, thereby ensuring that the sewage enters the housing 110 through the water inlet groove 116;

[0075] Sewage from the bottom of the anaerobic tank 200 enters, anaerobic reaction occurs at the bottom of the anaerobic tank 200, due to microbial reproduction and bubble generation, in the process of sewage upflow, gas and part of sludge mixture rise to the anaerobic device 100, under the action of the three-phase separator 130, the gas and sludge-water mixture is preliminarily separated, the sludge-water mixture enters the shell through the water inlet groove 116, under the action of the outer inclined plate 111 and the inner inclined plate 112 filler, the sludge-water mixture is separated, the sludge is precipitated in the shell 110, and falls to the bottom of the outer shell 201 through the partition plate 120 and the top of the three-phase separator 130 to carry out reaction again;

[0076] Compared with the prior art, the anaerobic device 100 is arranged outside the anaerobic tank 200, which is more space-saving and improves the processing efficiency.
