The operation of the delay tank assembly 10 in the cistern assembly 6 is described: when sewage flows into the water storage tank assembly 6, the blocking float 10-4 rises to block the water outlet 10-3 of the delay tank along with the rise of the water level, part of the sewage flows into the water receiving tank 15 of the next layer of standard layer component 3 through the delay water leakage pipe 10-8, and part of the sewage flows into the delay tank 10-2 along with the rise of the water level. The delay float 10-1 moves upwards under the action of water buoyancy, and the delay float 10-1 rotates to enable the delay ball 10-7 on the pull rod assembly 10-5 to move downwards to block the delay water leakage pipe 10-8. When the water storage tank assembly 6 discharges sewage from a full water state, the plugging float 10-4 moves downwards along with the downward movement of the water level to open the water outlet 10-3 of the delay tank, the sewage in the delay tank 10-2 is discharged, the delay float 10-1 moves downwards, the delay float 10-1 rotates to enable the delay ball 10-7 on the pull rod assembly 10-5 to move upwards, and the delay water leakage pipe 10-8 is opened.

The closing and opening of the water stop float 9-4 and the water stop float support 9-5 in the upper water tank assembly 5 or the water storage tank assembly 6 are controlled through the structure arranged in the water receiving tank 15, and the specific mode is as follows: 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 member 3 is in a water-free state, the upper tank member 2 is in a full water state.

The following is an example of the water tank part 2 being in a full water state and the uppermost standard layer part 3 being in a no water state, and the operation mode of the structure arranged in the water receiving tank 15 for closing and opening the water stop float 9-4 and the water stop float support 9-5 in the upper water tank assembly 5 or the water storage tank assembly 6 is described in detail: when the water level of the upper water tank component 2 rises gradually, sewage of the upper water tank component 2 flows into the water receiving tank 15 of the uppermost standard layer component 3 through the delay water leakage pipe 10-8, then the water receiving tank floating body 16 in the water receiving tank 15 moves upwards under the action of buoyancy along with the increase of the water amount in the water receiving tank 15, the large float 8 and the sealing disc 8-3 below the water receiving tank floating body 16 are pulled to move upwards, the standard layer water outlet 17-1 of the uppermost standard layer component 3 is opened, the sewage of the uppermost standard layer component 3 flows out, at the moment, 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. Along with the effluent of the uppermost standard layer component 3, along with the decline of the water level in the water receiving tank 15, the water receiving tank below the water receiving tank water outlet 21 floats and descends immediately, the water receiving tank water outlet 21 is opened, the stored sewage in the water receiving tank 15 can be drained completely, at the moment, the upper water tank component 2 is in a full water state, the uppermost standard layer component 3 is in a water-free state, then the uppermost standard layer component 3 drains water according to the drainage mode, namely, the upper water tank component 2 and the uppermost standard layer component 3 alternately circulate between the full water state and the water-free state.

The standard layer parts 3 on each layer are internally provided with an oxygen increasing box 18, and the oxygen increasing box 18 in the lower standard layer part 3 is positioned below the lower bottom plate combination part 17 of the upper standard layer part 3 and is used for increasing the oxygen content of the sewage of the upper standard layer part 3 after falling to the lower standard layer part 3.

The water baffle 20 is arranged between the oxygen increasing box 18 and the time-delay water leaking pipe 10-8 in the vertical direction, and the arrangement mode can avoid that sewage enters the oxygen increasing box 18 in the falling oxygen increasing process to influence the time-delay effect.

The intermittent potential energy biological sewage purifier is used for treating sewage acted by filtering equipment or anaerobic equipment, the sewage sequentially passes through the upper water tank component 2 and the plurality of layers of standard layer components 3 through the water inlet pipe 1 and flows out from the water receiving tank water outlet 21 of the last layer of standard layer component 3; when sewage passes through each layer of standard layer component 3, intermittent biochemical treatment is carried out in the biological filler 14 box in the standard layer component 3, so that the content of each index in the sewage is greatly reduced.

In order to fix the shapes of the upper water tank component 2 and the standard layer component 3 and improve the stability and the service performance of fixing the upper water tank component 2 and the standard layer component 3, cross braces are arranged on the top of the upper water tank component 2 and the top of the standard layer component 3, wherein the cross brace on the top of the standard layer component in the standard layer component 3 is marked as 13 as shown in fig. 8.

Along with the rising of the water level in the upper water tank assembly 5, the water stop float 9-4 in the upper water tank assembly 5 rises to block the floating tank 9-3, sewage enters the floating tank 9-3 from the water inlet of the floating tank assembly 9-9, along with the rising of the water level in the floating tank 9-3, the floating tank float 9-2 drives the floating tank floating frame 9-1 to move upwards, and meanwhile, the buoyancy received by the large float 8-2 is also gradually increased.

As the water level in the upper water tank assembly 5 continues to rise, the buoyancy force borne by the large float 8-2 is increased; the further rising of the water level in the floating box 9-3, the jacking force of the floating frame 9-1 of the floating box to the lever conjunction 7 is larger, until the water level rises to the set stage, the lever conjunction 7 pulls the large floating assembly 8 in the upper water box assembly 5 to rise to open the large floating water outlet 11 of the upper water box, and presses the large floating assembly 8 in the water storage box assembly 6 to fall to close the large floating water outlet 12 of the water storage box. In the process, the liquid in the balance bar 7-1 sensitively improves the opening and closing effects thereof along with the action of the lever joint 7.

As the large float assembly 8 opens the reservoir large float outlet 12, the water level within the reservoir assembly 6 gradually falls and the large float assembly 8 gradually moves downward. The sewage in the floating box combining piece 9 is drained because the water stop float 9-4 moves downwards, the small float 9-7 moves downwards to seal the water inlet on the floating box combining box 9-9, and the floating box floating frame 9-1 moves downwards gradually. Meanwhile, the delay float 10-1 seals the water leakage pipe 10-8 under the buoyancy action of sewage in the delay tank 10-2, the blocking float 10-4 moves downwards along with the downward movement of the water level to open the water outlet 10-3 of the delay tank, the sewage in the delay tank 10-2 is discharged, the delay float 10-1 moves downwards, the delay float 10-1 rotates to enable the delay ball 10-7 on the pull rod assembly 10-5 to move upwards, and the delay water leakage pipe 10-8 is opened until no sewage exists in the water storage tank assembly 6.

Sewage in the water storage tank assembly 6 enters the oxygen increasing tank 18 of the first-layer standard layer component 3 through the large floating water outlet 12 of the water storage tank, the sewage gradually flows through all components in the first-layer standard layer component 3 after the oxygen increasing effect is achieved, the sewage submerges the filler bottom pipe 19, the biological filler 14 and the oxygen increasing tank 18 along with the increase of the water level of the sewage in the first-layer standard layer component 3, the water receiving tank stops floating to seal the water receiving tank outlet 21 until the first-layer standard layer component 3 is full of water, and the water stops for 2 min. The sewage flows into a water receiving tank 15 of a second layer from a time-delay water leakage pipe 10-8 in a first layer of standard layer components 3, along with the rising of the water level of the water receiving tank 15 of the second layer, a water receiving tank floater 16 rises to drive a second layer of large floating assembly 8 to open a water outlet of the second layer of standard layer components 3, and the sewage of the second layer of standard layer components 3 flows into an oxygen increasing tank 18 of a third layer of standard layer components 3 through a lower bottom plate water outlet 17-2 of a lower bottom plate assembly 17.
