Liquid can be poured into the inner cavity of the balance bar 7-1 through the opening 7-4. The poured liquid The liquid is generally not larger than one-third of the inner cavity volume of the balance bar 7-1. The liquid is poured into the inner cavity of the balance bar 7-1 to adjust the sensitivity and timeliness of the lever assembly 7; the left and right ends of the balance bar 7-1 are respectively connected to the large floating assembly 8 of the upper water tank assembly 5 and the large floating assembly 8 of the water storage tank assembly 6 through a flexible body (a hanging rope in this embodiment); the floating tank combination 9 in the upper water tank assembly 5 and the floating tank combination 9 in the water storage tank assembly 6 are symmetrically arranged on the left and right sides of the lever bracket 7-3.

The small floating column 9-8 penetrates downward into the water inlet of the floating box distribution box 9-9 and blocks the water inlet. The right side of the floating box distribution box 9-9 is connected to the floating box 9-3.

[0059] When the water level in the upper water tank assembly 5 or the water storage tank assembly 6 rises, the floating box float 9-2 floats up due to the buoyancy of the water, driving the floating box float frame 9-1 to lift one end of the balance rod 7-1, thereby pulling open the large floating assembly 8 at the near end of the floating box combination 9; when the water level drops, the floating box float 9-2 drops down due to the buoyancy of the water, driving the floating box float frame 9-1 to drop down, causing one end of the balance rod 7-1 to gradually lose the lifting force, thereby causing the large floating assembly 8 at the near end of the floating box combination 9 to sink.

[0060] like Figure 6 As shown, a delay box assembly 10 is also provided in the water storage tank assembly 6, and the delay box assembly 10 includes a delay box 10-2 and a delay water leakage pipe 10-8 provided on one side of the delay box 10-2;

[0064] Describe the operation mode of the floating box assembly 9 in the upper water tank assembly 5: When the amount of sewage entering the upper water tank assembly 5 is large, the water-stop float 9-4 moves upward under the action of buoyancy to block the flowing water hole and seal the floating box 9-3; the small floating body 9-7 moves upward under the action of buoyancy, thereby driving the small floating column 9-8 to move out of the water inlet of the floating box distribution box 9-9, opening the water inlet on the floating box distribution box 9-9, and the sewage enters the floating box 9-3 through the floating box distribution box 9-9. The floating box float 9-2 in the floating box 9-3 jacks up the floating box floating frame 9-1 under the action of water buoyancy, and the balance rod 7-1 pulls up the large floating assembly 8 in the water inlet tank assembly 5, opening the large floating water outlet 11 of the upper water tank, and the sewage flows into the water storage tank assembly 6; at the same time, the large floating assembly 8 in the water storage tank assembly 6 seals the large floating water outlet 12 of the water storage tank, the water level in the water storage tank assembly 6 rises, and the water level in the upper water tank assembly 5 drops.

[0065] As the water level in the upper water tank assembly 5 drops, the water-stop float 9-4 moves downward, and the floating box 9-3 discharges water through the flowing water hole. The floating box float 9-2 then drops, driving the floating box floating frame 9-1 to drop, and the balance rod 7-1 gradually loses the top force and moves downward; at the same time, the water level in the water storage tank assembly 6 continues to rise, the large floating water outlet 11 in the upper water tank assembly 5 is closed, and the large floating water outlet 12 in the water storage tank assembly 6 is immediately opened.

[0071] The water receiving box 15 of the odd-numbered standard floor component is located directly below the delayed leakage pipe 10-8 of the upper standard floor component 2; a small amount of sewage in the water storage tank assembly 6 flows into the water receiving box 15 of the odd-numbered standard floor component through the delayed leakage pipe 10-8; the delayed leakage pipe 10-8 is periodically opened and closed by the action of water buoyancy, so that the sewage can be periodically distributed in the water storage tank combination 6 and the standard floor component 3.

[0072] The operation of the delay tank assembly 10 in the water storage tank assembly 6 is described as follows: when sewage flows into the water storage tank assembly 6, as the water level rises, the blocking float 10-4 rises to block the delay tank outlet 10-3, and part of the sewage flows into the water receiving box 15 of the next standard layer component 3 through the delay leakage pipe 10-8. As the water level rises, part of the sewage flows into the delay tank 10-2. The delay float 10-1 moves upward under the buoyancy of the water, and the delay float 10-1 rotates to move the delay ball 10-7 on the pull rod assembly 10-5 downward to block the delay leakage pipe 10-8. When the water storage tank assembly 6 discharges sewage from a full water state, as the water level moves down, the blocking float 10-4 moves down to open the delay box outlet 10-3, the sewage in the delay box 10-2 is discharged, the delay float 10-1 moves down, and the delay float 10-1 rotates to move the delay ball 10-7 on the pull rod assembly 10-5 up, opening the delay leakage pipe 10-8.

[0073] The closing and opening of the water stop float 9-4 and the water stop float bracket 9-5 in the upper water tank assembly 5 or the water storage tank assembly 6 are controlled by the structure arranged in the water receiving box 15. The specific method is: if the uppermost standard layer component 3 is in a full water state, the upper water tank component 2 is in a water-free state; if the uppermost standard layer component 3 is in a water-free state, the upper water tank component 2 is in a full water state.

[0074] The following takes the example where the upper water tank component 2 is in a full water state and the uppermost standard layer component 3 is in a water-free state, and describes in detail the operation mode of the structure arranged in the water receiving box 15 to close and open the water-stopping float 9-4 and the water-stopping float bracket 9-5 in the upper water tank assembly 5 or the water storage tank assembly 6: when the water level of the upper water tank component 2 gradually rises, the sewage of the upper water tank component 2 will flow into the water receiving box 15 of the uppermost standard layer component 3 through the delayed leakage pipe 10-8. As the water amount in the water receiving box 15 increases, the water receiving box float 16 in the water receiving box 15 moves upward under the buoyancy, pulling the large float 8 and the sealing plate 8-3 under the water receiving box float 16 to move upward, opening the standard layer water outlet 17-1 of the uppermost standard layer component 3, and the sewage of the uppermost standard layer component 3 flows out. At this time, the upper water tank component 2 is in a water-free state, and the uppermost standard layer component 3 is in a full water state. As the sewage from the uppermost standard layer component 3 flows out and the water level in the water receiving box 15 drops, the water receiving box water stop float provided below the water receiving box outlet 21 drops immediately, opening the water receiving box outlet 21, and the stored sewage in the water receiving box 15 is drained. At this time, the upper water tank component 2 is in a full water state, and the uppermost standard layer component 3 is in a dry state. Then, the uppermost standard layer component 3 is drained according to the aforementioned drainage method, that is, the upper water tank component 2 and the uppermost standard layer component 3 alternate between a full water state and a dry state.

[0075] An oxygenation box 18 is provided in each standard layer component 3. The oxygenation box 18 in the lower standard layer component 3 is located below the lower bottom plate combination 17 of the upper standard layer component 3, and is used to increase the oxygen content of the sewage in the upper standard layer component 3 after it falls to the lower standard layer component 3.

[0076] The water baffle 20 is located between the aeration box 18 and the delayed leakage pipe 10-8 in the vertical direction. This arrangement can prevent sewage from falling into the aeration box 18 during the aeration process and affecting the delay effect.

[0077] The intermittent potential energy biological sewage purifier of the present invention is used to treat sewage after being acted upon by filtering equipment or anaerobic equipment. The sewage passes through the water inlet pipe 1 in turn through the upper water tank component 2 and several layers of standard layer components 3, and flows out from the water outlet 21 of the water receiving tank of the last layer of standard layer components 3; when the sewage passes through each layer of standard layer components 3, it will undergo intermittent biochemical treatment in the biological filler 14 box in the standard layer component 3, thereby greatly reducing the content of various indicators in the sewage.

[0078] In order to fix the shapes of the upper water tank component 2 and the standard layer component 3 and improve the stability and performance of the upper water tank component 2 and the standard layer component 3, the top of the upper water tank component 2 and the top of the standard layer component 3 are both provided with cross braces, wherein, Figure 8 As shown, the top cross brace of the standard floor component in the standard floor component 3 is marked as 13.

[0079] Operation principle: The case where there is no water in the water tank assembly 5 is taken as an example for introduction. At this time, the water storage tank assembly 6 and the even-numbered standard layer component 3 are full of water, and the odd-numbered standard layer component 3 is empty.

[0080] The large floating assembly 8 in the upper water tank assembly 5 blocks the large floating water outlet 11 of the upper water tank. At this time, the floating box combination 9 in the upper water tank assembly 5 is located at the lowest end, the large floating assembly 8 in the water storage tank assembly 6 opens the large floating water outlet 12 of the water storage tank, and the floating box combination 9 in the water storage tank assembly 6 is located at the top. The delay ball 10-7 of the delay box assembly 10 seals the delay leakage pipe 10-8.

[0081] As the water level in the upper water tank assembly 5 rises, the water stop float 9-4 in the upper water tank assembly 5 rises to seal the floating box 9-3, and the sewage enters the floating box 9-3 from the water inlet of the floating box distribution box 9-9. As the water level in the floating box 9-3 rises, the floating box float 9-2 drives the floating box float frame 9-1 to move upward. At the same time, the buoyancy of the large float 8-2 is gradually increased.

[0082] As the water level in the upper water tank assembly 5 continues to rise, the buoyancy of the large float 8-2 increases; as the water level in the float box 9-3 further rises, the floating frame 9-1 exerts a greater force on the lever combination 7, until the water level rises to the set stage, the lever combination 7 pulls the large float assembly 8 in the upper water tank assembly 5 upward to open the upper water tank large float outlet 11, and presses the large float assembly 8 in the water storage tank assembly 6 downward to close the water storage tank large float outlet 12. In this process, the liquid in the balance bar 7-1 will sensitively improve its opening and closing effects with the action of the lever combination 7.

[0083] As the large floating assembly 8 opens the large floating outlet 12 of the water storage tank, the water level in the water storage tank assembly 6 gradually decreases, and the large floating assembly 8 gradually moves down. The sewage in the floating tank assembly 9 is discharged due to the downward movement of the water stop float 9-4, and the small float 9-7 moves down to seal the water inlet on the floating tank distribution box 9-9, and the floating frame 9-1 of the floating tank gradually moves down. At the same time, the delay float 10-1 seals the leakage pipe 10-8 under the buoyancy of the sewage in the delay box 10-2. As the water level moves down, the blocking float 10-4 moves down to open the delay box outlet 10-3, and the sewage in the delay box 10-2 is discharged. The delay float 10-1 moves down, and the delay float 10-1 rotates to make the delay ball 10-7 on the pull rod assembly 10-5 move up, opening the delay leakage pipe 10-8 until there is no sewage in the water storage tank assembly 6.

[0084] The sewage in the water storage tank assembly 6 enters the oxygenation box 18 of the first standard layer component 3 through the large floating outlet 12 of the water storage tank. After the oxygenation, the sewage gradually flows through various components in the first standard layer component 3. As the sewage water level in the first standard layer component 3 increases, the sewage submerges the filler bottom pipe 19, the biological filler 14, and the oxygenation box 18. The water stop float of the water receiving tank will seal the water receiving tank outlet 21 until the first standard layer component 3 is full of water, and stay for 2 minutes. The sewage flows into the second layer of the water receiving tank 15 through the delayed leakage pipe 10-8 in the first standard layer component 3. As the water level of the second layer of the water receiving tank 15 rises, the water receiving tank float 16 rises and drives the second layer large floating assembly 8 to open the outlet of the second layer of the standard layer component 3. The sewage in the second layer of the standard layer component 3 flows into the oxygenation box 18 of the third layer of the standard layer component 3 through the lower bottom plate outlet 17-2 of the lower bottom plate combination 17.

[0085] As the water level of the second standard floor component 3 drops, the water receiving box stop float opens the water receiving box outlet 21, and the delay float in the delay box assembly below the water receiving box 15 seals the leaking pipe under the buoyancy of the sewage in the delay box. As the water level moves down, the blocking float moves down to open the delay box outlet, and the sewage in the delay box is discharged. The delay float moves down, and the delay float rotates to move the delay ball on the pull rod assembly upward, opening the delay leaking pipe and draining the sewage in the water receiving box 15. After the sewage in the second standard floor component 3 is drained, the large floating assembly 8 in the second standard floor component 3 closes the outlet of this layer.
