Through such a design, the sealing of the reactor 1 is ensured when the water inlet pump 5 and the emptying pump 2 are not working, avoiding the backflow of sewage.

[0029] Further, in the present embodiment, the overflow hole is above the water inlet opening.

[0030] In the present embodiment, one end of the overflow pipe 3 communicates with the adjusting tank, so that the overflow sewage in the reactor 1 can be directly discharged into the adjusting tank through the overflow pipe 3, and one end of the emptying pipe 21 also communicates with the adjusting tank, through such independent installation mode, when the sewage in the reactor 1 is too much, the internal sewage is discharged at the same time, improving the discharge speed, specifically, the end of the overflow pipe 3 away from the overflow tank communicates with the adjusting tank, and the end of the emptying pipe 21 away from the emptying pump 2 communicates with the adjusting tank.

[0035] Working principle:

[0036] In a normal working state, the water inlet system and the water outlet system operate normally, under the control of the controller 41, the normal operation of the reactor 1 and the height range of the liquid level inside the reactor 1 are ensured to be between the highest liquid level and the lowest liquid level, in this state, the emptying pump 2 and the first valve 22 and the third valve 31 do not work, the water inlet pump 5 of the water inlet system and the second valve 52 work in linkage, it should be noted that when the water outlet system is the secondary sedimentation tank system 8, a normally open fourth valve 82 is arranged outside the overflow weir 81 for draining water in the secondary sedimentation tank system 8, in this state, the fourth valve 82 is in a non-working state, and the water outlet system operates intermittently; when the water outlet system is the membrane water production system 9, the water inlet pump 5 and the water production pump 92 both operate intermittently;

[0037] In the special state, for example, in case one, the water inlet pump 5 fails to normally feed water, and the water outlet system normally feeds water, as the water volume decreases, the liquid level detected by the liquid level meter 43 is lower than the minimum liquid level value, the controller 41 controls the alarm device to alarm; in the embodiment, the alarm device is an audible and visual alarm 42, which is used to remind the staff that the reactor 1 fails and needs to be handled; in case two, in heavy rain, a large amount of rainwater enters the reactor 1, causing the rainwater to continuously rise, when the liquid level meter 43 detects that the sewage liquid level height is higher than the maximum liquid level value, the controller 41 controls the water inlet system to stop working, and simultaneously opens the emptying pump 2 and the first valve 22, and closes the third valve 31, until the liquid level returns to the normal working state liquid level; after the emptying pump 2 is opened for a period of time, the liquid level information received by the controller 41 is always greater than the maximum liquid level value, and the secondary phenomenon occurs under these conditions, for example, the water inlet amount of rainwater is greater than the water outlet amount or the emptying pump 2 fails to cause the water to be unable to be drained or the first valve 22 fails to cause the adjusting tank to be full and the like, which will cause the liquid level value of the liquid level meter 43 to be greater than the maximum liquid level value, at this time, the controller 41 immediately controls the audible and visual alarm 42 to alarm, and sends a short message or a telephone alarm through the alarm module set in the controller 41, reminding the operator that the reactor 1 fails and needs to be handled immediately. In addition, it should be noted that if the water outlet system is a secondary sedimentation tank system 8, the fourth valve 82 is in a closed working state to prevent the sewage from flowing out of the overflow weir 81; in case three, the equipment is prepared to be suspended, to prevent the integrated equipment from floating up in heavy rain, before power-off, the water inlet system is opened, and the liquid level in the reactor 1 is filled to the maximum liquid level.

[0038] Further, in the embodiment, the controller 41 is provided with a display panel, through the display panel, the liquid level height and the working state of the equipment can be directly and intuitively observed on site.

[0039] Referring to Figure 2 In some embodiments, the bottom of the reactor 1 is provided with a blowdown port 7, the sewage in the reactor 1 can be completely emptied, and the dirt in the reactor 1 can be cleaned in the later stage.

[0040] In summary, in the integrated sewage treatment device in the above-mentioned embodiments of the utility model, the liquid level height in the reactor is detected by the liquid level meter arranged in the reactor, the height information detected by the liquid level meter is received by the controller, and the liquid level value pre-set in the controller is compared, and then the working states of the water inlet system, the water outlet system and the emptying pump are controlled, so that the liquid level in the reactor is ensured to be in a normal range; in addition, the utility model is also provided with an alarm device, when the liquid level value is greater than the maximum liquid level value or less than the minimum liquid level value, the alarm device alarms, reminding the operator to manually handle.
