Along with the continuous inflow of water flow into the first-layer potential energy biological sewage purification box body 1 in the first-layer potential energy biological sewage purification box body 4-1, the water level in the first-layer potential energy biological sewage purification box body 1 rises, the plugging float 9-4 of the delay box assembly 9 rises to plug the delay box water outlet 9-3, sewage enters the delay box 9-2, and the delay float 9-1 seals the water leakage pipe 9-7 under the action of sewage buoyancy in the delay box 9-2.
The water level in the first-layer potential energy biological sewage purifying box body 1 continuously rises, and the floating box water stop ball 3-6 of the floating box assembly 3 floats along with the floating box water stop floating body 3-7 to block the water outlet 3-8 of the floating box.
The water level in the first-layer potential energy biological sewage purifying box body 1 continuously rises, sewage enters the floating box body 3-4 of the floating box assembly 3, along with the rising of the water level in the floating box body 3-4, the floating 3-3 rises along the guide pipe, meanwhile, the purifier box body water outlet sealing plate 8-2 is driven to rise, the purifier box body water outlet 8-3 is opened, the sewage in the first-layer potential energy biological sewage purifying box body 1 (odd-layer potential energy biological sewage purifying box body) flows through the purifier box body water outlet 8-3 through the purifier box body long hole 8-6, dissolved oxygen is increased in a water splitting mode, DO reaches 6mg/L, and the sewage flows into the purifier box body one zone 4-1 on the right side of the second-layer potential energy biological sewage purifying box body 2 (even-layer potential energy biological sewage purifying box body).
The water level in the first-layer potential energy biological sewage purifying box body 1 is lowered, the plugging float 9-4 is moved downwards to open the water outlet 9-3 of the delay box, sewage in the delay box 9-2 is discharged, the delay float 9-1 is rotated to enable the delay ball 9-6 on the pull rod assembly 9-5 to move upwards, the sewage flows into the floating box assembly 3 in the second-layer potential energy biological sewage purifying box body 2, the floating 3-3 is lifted along the guide pipe along with the rising of the water level of the floating box body 3-4, the purifier box body water outlet sealing plate 8-2 is driven to rise at the same time, the purifier box body water outlet 8-3 is opened, the sewage in the first-layer potential energy biological sewage purifying box body 1 flows through the purifier box body water outlet 8-3 to be discharged through the purifier box body water long hole 8-6, and accordingly the purifier box body water outlet 8-3 of the second-layer potential energy biological sewage purifying box body is controlled to discharge water.
The water level in the first-layer potential energy biological sewage purifying box body 1 continuously descends, the floating box water stop floating body 3-7 descends with the floating box water stop ball 3-6 to open the sealed floating box water outlet 3-8, so that sewage in the floating box body 3-4 in the floating box assembly 3 is discharged into the purifier box body three region 4-3 of the first-layer potential energy biological sewage purifying box body 1 from the floating box water outlet 3-8 and flows into the purifier box body one region 4-1 of the second-layer potential energy biological sewage purifying box body 2 through the purifier box body water outlet 8-3 and the purifier box body long hole 8-6. And sewage enters the third-layer potential energy biological sewage purifying box body through the second-layer potential energy biological sewage purifying box body in the same mode, and finally flows through the potential energy biological sewage purifying box bodies in each layer in sequence.
Further, between the potential energy biological sewage purifying box bodies of two adjacent layers, the potential energy biological sewage purifying box bodies of the lower layer can control the water inlet and the water outlet of the potential energy biological sewage purifying box bodies of the upper layer, and the potential energy biological sewage purifying box bodies of the lower layer are specifically:
When the upper potential energy biological sewage purification box body starts to inject water into the lower potential energy biological sewage purification box body in a large quantity through the long hole 8-6 of the purifier box body, the blocking ball 10-1 closes the blocking ball water leakage pipe 10-3 by means of self weight, the blocking ball control float 10-6 is subjected to buoyancy along with the rising of the water level of the lower potential energy biological sewage purification box body, so that the blocking ball 10-1 is driven to open the blocking ball water leakage pipe 10-3, and the upper potential energy biological sewage purification box body starts to inject water into the floating box body 3-4 of the floating box assembly of the lower potential energy biological sewage purification box body slowly through the blocking ball water leakage pipe 10-3. At this time, the upper potential energy biological sewage purifying box body is injected with a large amount of water to the lower upper potential energy biological sewage purifying box body through the long hole 8-6 of the water, and simultaneously, the upper potential energy biological sewage purifying box body is slowly injected into the floating box body 3-4 of the floating box assembly in the lower upper potential energy biological sewage purifying box body through the plugging ball water leakage pipe 10-3, and the two water injection modes have the time difference required to control the stay on the process design requirement, and the time difference can be adjusted by changing the relative position of the plugging ball control float 10-6 fixed at the lower end of the plugging ball connecting rod 10-2.
After the water level of the floating box body 3-4 of the lower potential energy biological sewage purifying box body floating box assembly rises to a set height, the floating box body 3-3 rises along the guide pipe and drives the purifier box body water outlet sealing plate 8-2 to rise, the purifier box body water outlet 8-3 is opened, sewage in the potential energy biological sewage purifying box body 1 passes through the purifier box body water outlet 8-3, and flows into the lower potential energy biological sewage purifier from the purifier box body water splitting slot 8-6.
