[0021] Please see Figure 1-7 This utility model provides a technical solution: a cement septic tank with a three-compartment sedimentation and filtration structure. Figure 1-3 This first embodiment of the utility model includes a septic tank body 1, characterized in that: the septic tank body 1 is composed of a first mounting component 101, a second mounting component 102, and a third mounting component 103 stacked and spliced ​​together; a first partition plate 2 and a second partition plate 3 are fixedly connected inside the septic tank body 1, dividing the interior of the septic tank body 1 into three sedimentation chambers, which are, from left to right, a first sedimentation chamber 4, a second sedimentation chamber 5, and a third sedimentation chamber 6; and a septic inlet hole 7 is provided on the left side of the third mounting component 103. The third mounting component 103 has a discharge hole 8 on its right side, the first partition plate 2 has a first filter hole 9 in the middle, and the second partition plate 3 has a second filter hole 10 in the middle. The first filter hole 9 and the second filter hole 10 are used to filter feces in different sedimentation states. The connection of the first mounting component 101, the second mounting component 102, and the third mounting component 103 is a stepped structure to achieve positioning and snap-fit. The connection structure is the same, and hoisting and splicing can be easily achieved through the first mounting component 101, the second mounting component 102, and the third mounting component 103.

[0022] The volume ratio of the first sedimentation chamber 4, the second sedimentation chamber 5, and the third sedimentation chamber 6 is 2:1:3, which realizes efficient utilization of the internal space of the septic tank body 1, enables the recycling of sewage, and ensures efficient utilization of the septic tank's containment space.

[0023] Both the manure inlet 7 and the discharge outlet 8 are located at the third mounting component 103, with the manure inlet 7 being higher than the discharge outlet 8.

[0024] The first filter hole 9 and the second filter hole 10 are both located in the middle of the second mounting component 102. The first filter hole 9 and the second filter hole 10 are both inclined, and the inclination angle is 5-30 degrees, so that the clean sewage after sedimentation at the lower end can flow easily. The first filter hole 9 is lower than the second filter hole 10. The sewage and excrement are fully sedimented and filtered through the first filter hole 9 and the second filter hole 10, realizing the recycling of sewage.

[0025] The first mounting component 101 has a first snap-fit ​​groove 11 on its side, and the second mounting component 102 has a second snap-fit ​​groove 12 on its side. Both the first snap-fit ​​groove 11 and the second snap-fit ​​groove 12 are inclined structures. A snap-fit ​​block 13 is slidably connected inside the first snap-fit ​​groove 11. A pressing column 16 is inserted into the first snap-fit ​​groove 11. The upper end of the pressing column 16 abuts against the snap-fit ​​block 13, and the lower end of the pressing column 16 is flush with the outer wall of the first mounting component 101. The pressing column 16 is hollow in the middle, and two locking blocks 14 are inserted in the middle of the pressing column 16. The locking blocks 14 are triangular structures, and a rubber strip 15 is provided between the two locking blocks 14. During the splicing process of the first mounting component 101, the second mounting component 102, and the third mounting component 103, for example, the first mounting component 101 and the second mounting component 102... Both connections are stepped structures for positioning and locking. By inserting the extrusion column 16 into the first mounting member 101 below, the locking block 14 is located inside the extrusion column 16, compressing and storing force on the rubber strip 15 until the extrusion column 16 pushes up the locking block 13, which is then inserted into the second locking groove 12, thus limiting and fixing the first mounting member 101 and the second mounting member 102. At this time, the locking block 14 pops out under the action of the rubber strip 15, thereby locking the locking block 14 into the first locking groove 11. The extrusion column 16 limits and fixes the locking block 13, thus limiting and fixing the first mounting member 101 and the second mounting member 102 to each other. Cement is then injected into the middle part of the extrusion column 16 to fill and seal the interior, ensuring the sturdiness of the septic tank body 1.
