[0002] At present, the deep biological treatment technology combining activated sludge and biological contact oxidation process is mainly used for sewage treatment at home and abroad. Although the treated water quality can meet the standards of reused water, the aerobic process mostly adopts the method of forced aeration, which has low reoxygenation efficiency, high energy consumption and high operating costs. The Chinese patent with application number CN201620842528.8 discloses a water supply device for a potential reoxygenation sewage treatment parallel system, which pulls up the water supply pipe through a buoyancy control mechanism to drain the water into the water supply tank on the other side. Although it can achieve full automatic control without the need for special personnel management during the water supply process, its applicability is not high due to its overly complex structure.

[0048] As Figure 3 shown in the figure, a water storage tank outlet combination part 20 is provided at the bottom of the water storage tank body 3. The water storage tank outlet combination part 20 includes a clamping groove provided on the lower surface of the water storage tank body 3 and a purifier box body water outlet groove provided on the lower surface of the clamping groove. The clamping groove is provided directly below the floating box 17-1. A water storage tank outlet 20-3 is provided on the bottom plate of the water storage tank body 3 corresponding to the position of the floating box 17-1. A water storage tank sealing plate 20-2 is provided at the water storage tank outlet 20-3. A water storage tank shaft 20-1 capable of penetrating into the guide pipe is provided at the top end of the water storage tank sealing plate 20-2.

[0049] The bottom plate 20-6 of the water outlet tank of the purifier box body is provided with a number of water storage tank water spraying long holes 20-4 arranged in parallel. The lower surface of the bottom plate 20-6 of the water outlet tank of the purifier box body is provided with a water storage tank bottom plate reinforcing rib 20-5 perpendicular to the extending direction of the water storage tank water spraying long hole 20-4. The water storage tank bottom plate reinforcing rib 20-5 is used to strengthen the strength of the bottom plate 20-6 of the water outlet tank of the purifier box body and prevent the deformation of the bottom plate 20-6 of the water outlet tank of the purifier box body caused by long-term use.

[0050] The upper water tank water outlet 7 can evenly discharge the sewage in the upper water tank 2 into the water storage tank body 3, and can control the delay time of the quantitative intermittent water supply device by changing the aperture of the upper water tank water outlet 7 according to process requirements.

[0051] The larger the aperture of the upper water tank water outlet 7, the shorter the delay time of the quantitative intermittent water supply device; when the hole diameter of the upper water tank water outlet 7 is 100 mm, the delay time of the quantitative intermittent water supply device can be controlled to be about 5 min.

[0052] The quantitative intermittent water supply device is used for treating the sewage after the action of the filtration device or the anaerobic device. After the sewage passes through the water inlet pipe 1, it flows into the treatment layer of the potential energy biological sewage purifier through the upper water tank 2 and the water storage tank body 3 in sequence.

[0053] Operating principle: When the sewage is just injected into the upper water tank 2 from the water inlet pipe 1, the floating box assembly 17 drops to the lowest end due to its own gravity, thereby pulling the flexible body 10-1 of the support assembly to move to the left. The right end of the flexible body 10- of the support assembly pulls the upper water tank water outlet sealing plate shaft 9 upward and drives the upper water tank water outlet sealing plate 8 upward. At this time, the upper water tank body water outlet sealing plate 8 does not seal the upper water tank water outlet 7, and the water storage tank sealing plate 20-2 seals the water storage tank water outlet 20-3. The sewage flows from the upper water tank 2 into the water storage tank 3. As the water volume is injected, the floating box water stop float 19-2 drives the floating box water stop ball 19-1 to rise to seal the floating leakage hole 17-6, realizing the water storage function of the water storage tank body 3.

[0054] When the water level is higher than the floating box 17-1, the sewage enters the floating box assembly 17. As the water level in the floating box assembly 17 continues to rise with the entry of the sewage, the float 17-2 rises along the guide pipe, and at the same time drives the connected water storage tank shaft 20-1 to rise. The water storage tank shaft 20-1 drives the water storage tank sealing plate 20-2 to rise, thereby opening the water storage tank water outlet 20-3. The sewage in the water storage tank 3 flows through the water storage tank water outlet 20-3 through the water storage tank water spraying long hole 20-4, increases the dissolved oxygen by the way of water spraying, and flows into the treatment layer of the potential energy biological sewage purifier.

[0055] As the float 17-2 rises, the lead screw 17-3 connected to the float 17-2 rises, thereby driving the flexible body 10-1 of the bracket assembly connected to the lead screw 17-3 to move to the right. At this time, since the flexible body 10-1 of the bracket assembly moves to the right, it drives the stop block 13 to move to the right. The hanging rope on the stop block 13 pulls the right end of the rotating rod 15 to rotate upward. At this time, the stop block 13 passes over the top of the sliding member and finally falls to the right side of the sliding member and is located on the left side of the limit block 12. The maximum displacement of the stop block 13 is fixed by the limit block 12, and then the upper water tank outlet sealing plate shaft 9 drives the water tank outlet sealing plate 8 to descend, thereby sealing the upper water tank outlet 7.

[0056] Sewage continuously enters the water inlet pipe 1 and is stored in the upper water tank body 2. When the water level in the upper water tank body 2 rises to a certain level, the floating body 16 of the rotating rod floats upward, driving the right end of the rotating rod 15 to rotate downward, causing the stop block 13 to descend and move to the left. Due to the self-weight of the water storage tank sealing plate 20-2 and the floating box assembly 17, it drives the flexible body 10-1 of the bracket assembly to move downward. At this time, the upper water tank outlet sealing plate 8 moves upward along the upper water tank outlet sealing plate shaft 9 and opens the sealed upper water tank outlet 7. At the same time, the water storage tank sealing plate 20-2 seals the water storage tank outlet 20-3 under its own weight, and the water storage tank body 3 starts to store water.

[0057] As the sewage in the water storage tank body 3 is discharged, the floating box water stop float 19-2 drives the floating box water stop ball 19-1 to descend to open the sealed floating water leakage hole 17-6, so that the sewage in the floating box 17-1 of the floating box assembly 17 is discharged from the floating water leakage hole 17-6 into the water storage tank body 3 and then flows into the potential energy biological sewage purifier treatment layer through the water storage tank outlet 20-3 and the water storage tank water spraying long hole 20-4.

The content not described in detail in the specification of the present invention belongs to the well-known technology of those skilled in the art.
