[0036] It should be noted that the following detailed descriptions are all illustrative and are intended to provide further explanations of the present utility model. Unless otherwise specified, all technical and scientific terms used in the present utility model have the same meanings as those commonly understood by those of ordinary skill in the technical field to which the present utility model belongs.

[0037] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present utility model. As used herein, unless the present utility model clearly indicates otherwise, the singular forms are also intended to include the plural forms. In addition, it should also be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof;

[0038] As introduced in the background art, for the problems in the prior art, in order to solve the above technical problems, the present utility model proposes a household sewage integrated collection and treatment device.

[0039] In a typical embodiment of the present utility model, referring to Figure 1 、 Figure 2 as shown, a household sewage integrated collection and treatment device includes a first housing. From one side to the other side of the first housing, a first black water treatment tank 3, a second black water treatment tank 4, a second grey water treatment tank 6, and a first grey water treatment tank 5 are arranged in sequence. A first diversion pipe 7 is arranged between the first black water treatment tank 3 and the second black water treatment tank 4, and a second diversion pipe 8 is arranged between the first grey water treatment tank 5 and the second grey water treatment tank 6;

[0040] An adsorption filter material container 10 is arranged in the second black water treatment tank, and adsorption filter material is arranged in the adsorption filter material container. The first diversion pipe is communicated with the top side of the adsorption filter material container. An oil and residue separation container 10 is arranged in the first grey water treatment tank, and the grey water inlet pipe 2 is communicated with the oil and residue separation container 11. First water passing holes are arranged at the bottom and the periphery of the oil and residue separation container 11. A filtering container 12 is arranged in the second grey water treatment tank, the top side of the filtering container is communicated with the second diversion pipe, porous adsorption filler is arranged in the filtering container, and second water passing holes are arranged at the bottom of the filtering container.

[0041] In this embodiment, the total effective volume ratio of the black water area (the first black water treatment tank and the second black water treatment tank) to the grey water area (the first grey water treatment tank and the second grey water treatment tank) is 2:1, and the residence time in the black water area is longer; the two areas separated in the black water area and the grey water area are each partitioned in a ratio of 1:1.

[0042] Among them, the bottom of the adsorption filter material container 10 is provided with openings to allow the black water to flow out; the first black water treatment tank is provided with a black water inlet pipe 1, and the black water inlet pipe is connected to the discharge pipe of the toilet in the farmer's bathroom. The black water inlet pipe is bent downward by 30 cm to ensure that the black water is not blocked by the upper floating scum when entering the device. The black water undergoes sedimentation and anaerobic fermentation in the first black water treatment tank, and finally forms floating scum floating on the upper part of the first black water treatment tank and bottom sludge sinking to the bottom. After staying for a certain period of time, the black water enters the second black water treatment tank 4 through the first diversion pipe 7. Through the adsorption filter material in the second black water treatment tank, the first diversion pipe is connected to the top side of the adsorption filter material container. After the black water flowing in through the first diversion pipe 7 passes through the adsorption filter material 10 from top to bottom, the effective removal of carbon, nitrogen, and phosphorus is achieved; the black water adsorbed by the adsorption filter material 10 enters the chamber of the entire second black water treatment tank 4 through the bottom of the adsorption filter material 10.

[0043] After the black water of the farmer is purified in the black water area, the residence time in the black water area is not less than 30 days to make the black water harmless and meet the farmland irrigation standard. The black water outlet pipe 16 provided on the first housing outside the second black water treatment tank leads to the farmer's vegetable garden for the farmer to irrigate and utilize.

[0044] Specifically, the adsorption filter material includes activated carbon, zeolite, and sulfur filler. The activated carbon, zeolite, and sulfur filler are arranged in a volume ratio of 3:1:2, and the activated carbon, zeolite, and sulfur filler are arranged in layers from top to bottom. The adsorption filter material fills the adsorption filter material container. An inlet connected to the first diversion pipe is provided on the side of the adsorption filter material container, and a plurality of third water passing holes are provided at the bottom of the adsorption filter material container.

[0045] The first housing is provided with a first limiting member on the side wall of the second black water treatment tank 4 to limit the top of the adsorption filter material container. The first limiting member is rotatable relative to the first housing; similarly, a concave portion is provided on the side of the adsorption filter material container 10, and a convex portion is provided on the side wall of the second black water treatment tank of the first housing. Preliminary limiting is achieved through the cooperation of the convex portion and the concave portion.

[0046] In this embodiment, referring to Figure 4 As shown, the oil and slag separation container 11 includes a second housing 11-1. The width of the second housing is smaller than the width of the first gray water treatment tank. The second housing has a set height. The second housing is provided with a first water passing hole, and the diameter of the first water passing hole is less than or equal to 1 mm.

[0047] The first housing is provided with a plurality of first convex portions on the side wall of the first gray water treatment tank. A first concave portion 11-2 that cooperates with the first convex portions is provided on the side of the second housing. The distance between adjacent two first convex portions is set. The second housing is preliminarily limited through the cooperation of the first concave portion and the first convex portion.

[0048] The first housing is provided with a second limiting member 11-3 on the side wall of the first grey water treatment bin to limit the top of the second housing, and the second limiting member is rotatable relative to the first housing.

[0049] In this embodiment, the filtering container 12 includes a third housing, the volume of the third housing is smaller than the volume of the second grey water treatment bin where it is located. The third housing is along the height direction of the first housing. The first housing is provided with multiple second convex portions on the side of the second grey water treatment bin, and the side of the second housing is provided with second concave portions that cooperate with the second convex portions.

[0050] In this example, the filtering container contains porous adsorption filler. The porous adsorption filler includes gravel and activated carbon, and is mixed in a ratio of 2:1. The porous adsorption filler can have a particle size of 3-5 cm and a pore size of 5-30 nm. Both too small and too large pore sizes are not conducive to the adsorption of substances.

[0051] The first housing is provided with a third limiting member on the side wall of the second grey water treatment bin to limit the top of the third housing, and the third limiting member is rotatable relative to the first housing.

[0052] It should be noted that the structures of the first limiting member, the second limiting member, and the third limiting member are all the same. Specifically, they are all limiting plates. The limiting plates are installed on the inner wall of the first housing through pin shafts. When the corresponding components need to be taken out, the limiting plates are flipped to the vertical state, and the corresponding components can be taken out conveniently. When the components are put back, the limiting plates are flipped to the horizontal state.

[0053] In addition, both the first diversion pipe and the second diversion pipe are T-shaped. The T-shaped diversion pipe can ensure the passage of liquid while facilitating observation.

[0054] The grey water inlet pipe 2 passes through the first housing and enters the first grey water treatment bin to communicate with the top side of the oil separation and residue separation container 11. The household grey water discharged from the farmer's kitchen and other wash basins is connected through the grey water inlet pipe 2. The grey water inlet pipe 2 directly leads into the oil separation and residue separation container 11. The animal and vegetable oils in the grey water accumulate in the upper part of the oil separation and residue separation container 11, while other vegetable leaves, rice dregs, sediment, and sundries sink to the bottom of the oil separation and residue separation container 11. The grey water after effective oil separation and residue separation enters the first grey water treatment bin 5 through the first water passing holes at the bottom and the lower part of the periphery of the oil separation and residue separation container 11. The grey water enters the second grey water treatment bin 6 from the second diversion pipe 8, and the grey water after passing through the porous adsorption filler enters the chamber of the second grey water treatment bin 6. After the grey water of the farmer is purified in the grey water area, it meets the reuse standard and exits from the grey water area outlet pipe 17 connected to the second grey water treatment bin. The farmer can use it for courtyard cleaning with tools or introduce it into the small garden green belt of the farmer to irrigate various green plants.

[0055] The first housing is provided with a first opening at the top of the first black water treatment tank for maintaining the first black water treatment tank. The first housing is provided with a second opening at the top of the second black water treatment tank. The adsorption filter container 10 can be taken out and replaced through the second opening, and the second black water treatment tank can be maintained. The first housing is provided with a third opening at the top of the first grey water treatment tank and the second grey water treatment tank. The third opening is communicated with both the first grey water treatment tank and the second grey water treatment tank. The oil separation and residue removal container can be taken out from one side of the third opening for residue cleaning and animal and vegetable oil cleaning; the filter container can be taken out from the other side for cleaning or replacing the porous adsorption filler;

[0056] Openable covers are provided at the first opening 13, the second opening 14 and the third opening 15. The covers at the first opening and the second opening are circular covers. The first housing is provided with a top protruding part at each opening. Some covers can be threadedly connected to the top protruding part, and some covers can be buckled at the corresponding openings. After opening the covers corresponding to each opening, the flipping limit member is flipped to take out the corresponding components.

[0057] In addition, an overflow valve is provided between the second black water treatment tank and the second grey water treatment tank. The overflow valve is an existing valve. When it is necessary to mainly utilize the black water, the overflow valve 9 is opened, and the treated grey water is introduced into the second black water treatment tank through the overflow valve 9 to supplement the water volume for black water utilization and reduce the concentration of black water utilization, and more sufficient black water utilization is carried out through the black water area outlet pipe 16.

[0058] Reference Figure 3 As shown, black water area outlet pipes 16 and grey water area outlet pipes 17 are provided on both sides of the first housing. According to the different layouts of the sewage discharge pipes of each household, it is possible to flexibly select to discharge water from one side. When one side is selected as the black water area outlet pipe 16 and the grey water area outlet pipe 17, the reserved outlets on the other side can be directly blocked, which is convenient and flexible. This setting method can ensure that the black water inlet pipe 1 and the grey water inlet pipe 2 will not cross with the two black water area outlet pipes 16 and grey water area outlet pipes 17 during actual construction applications, which is beneficial for use.

[0059] Considering the seasonality or periodicity of water utilization in farmers' planting, the black water area outlet pipe 16 and the grey water area outlet pipe 17 are both set in the form of three-way joints and equipped with two ball valves. Usually, the ball valves for black water utilization and grey water utilization are always open. When the farmers do not need to use the water, the other two ball valves can be opened, and the ball valves for utilization are closed, so that the collected and treated black water and grey water can be introduced into the service well of the conventional sewage collection network.

[0060] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
