The stirring gas branch pipes 52 are all positioned in the biochemical tank 8, and the stirring gas branch pipes 52 are arranged on the stirring gas main pipe 51 and are communicated with the stirring gas main pipe 51. The stirring gas branch pipes 52 are located at two sides of the stirring gas main pipe 51 and are arranged in a rectangular array along the length direction of the stirring gas main pipe 51, preferably, 4 stirring gas branch pipes 52 are connected to two sides of the stirring gas main pipe 51 respectively, the stirring gas branch pipes 52 at two sides of the stirring gas main pipe 51 are symmetrically arranged, and the stirring gas main pipe 51 and the stirring gas branch pipes 52 are perpendicular to each other.

After the position of the air pressing disc 9 is fixed by using a limiting component, a gap is reserved between the air pressing disc 9 and the bottom of the biochemical pool 8, and the size of the gap is 0.5-1.5mm. Because the air pressing plate 9 can be used for exhausting air, after the air passes through the diversion pipe 14 and the air pressing plate 9, the air is exhausted from the gap between the air pressing plate 9 and the bottom of the biochemical pool 8,

illustratively, a manual valve 2 is mounted on the air supply duct for controlling the opening of the air supply duct, and the ventilation of the air supply duct can be controlled by manually closing or opening the manual valve 2. An electric aeration valve 3 is arranged on the main pipe of the aeration pipeline 6, and the ventilation of the aeration pipeline 6 can be controlled.

When stirring of sewage in the biochemical pond 8 is performed, the air supply to the stirring air pipeline 5 is controlled, and the air supply time for each time is set to be shorter, preferably, the air supply time for each time is controlled within 1 s. When the air is discharged from the air compressing disc 9, the air can impact the bottom of the biochemical pool 8, the sludge at the bottom of the pool is stirred and returns upwards, and because the air supply time is short, large-size bubbles are generated in a certain range around the air compressing disc 9, and the size of the bubbles is larger and larger along with the rising of the bubbles, so that liquid is driven to flow in a ring shape in the rising process of the bubbles, and the stirring effect is generated. After the bubbles rise to the liquid level and escape into the atmosphere, one stirring period is finished, short gas supply is carried out again, and the next stirring is carried out. The stirring of sewage in the biochemical tank 8 is carried out through the flowing of air, which is beneficial to the upward return and suspension of the deposited sludge at the bottom of the tank, thereby improving the working efficiency in the anoxic stage. And compare in mechanical stirring, do not need the waterproof problem of motor, reduced subsequent cost of maintenance.

after the fan 1 is started, air is conveyed to the biochemical tank 8 through a pipeline, in an aerobic stage, the aeration electric valve 3 is opened, the stirring electric valve 4 is closed, the fan 1 sends the air to the air supply pipeline, and then the air enters the aeration head 10 through the aeration main pipe 61 and the aeration branch pipe 62. The air is acted by the aeration head 10 to become a large amount of micro bubbles to be dispersed into the biochemical tank 8, thereby increasing the content of dissolved oxygen in the tank and improving the aerobic reaction efficiency. Because the aeration head 10 is arranged at a plurality of positions in the biochemical tank 8, air can be well diffused, the contact area of the air and the sewage in the biochemical tank 8 is large, and the dissolved oxygen in the sewage can be rapidly increased in an aerobic stage.

In the anoxic stage, the electric aeration valve 3 is closed, the electric stirring valve 4 is opened, air is finally conveyed to the air compressing plate 9 through the main stirring air pipe 51, the branch stirring air pipe 52 and the flow guide pipe 14 and is sprayed out from the small gap between the air compressing plate 9 and the tank bottom, large stirring flow is generated around the air compressing plate 9, sewage in the biochemical tank 8 is stirred through the air, and the anoxic reaction efficiency is improved. Meanwhile, the air in the air pressing disc 9 can be quickly sprayed out to stir the sludge at the bottom of the biochemical pool 8, so that the deposition at the bottom of the biochemical pool is reduced. Although the stirring process and the aeration process are both realized by air, the bubbles generated in the stirring stage are large-size and aggregation-shaped bubbles, the bubbles in the aeration process can be small-size and discrete-type bubbles, and the bubbles sprayed out from the bottom of the air compressing plate 9 in the stirring process are not easy to increase the oxygen content in the sewage, so that the stirring operation is convenient in the stage of anoxic treatment. In the stirring process, the stirring interval refers to an interval between two times of air introduction, the air supply time refers to a time when the stirring air pipe 5 and the draft tube 14 are introduced with air once, and the stirring process can be controlled by controlling the stirring interval and the air supply time.

Illustratively, the aeration and stirring integrated device further comprises a detection mechanism and a control cabinet 11, wherein the detection mechanism comprises a solid content probe 12 and a dissolved oxygen probe 13 which are installed on the biochemical pool 8, the solid content probe 12 is used for measuring the solid content of the sewage in the biochemical pool 8, and the dissolved oxygen probe 13 is used for measuring the oxygen content of the sewage in the biochemical pool 8. Preferably, the solid content probe 12 and the dissolved oxygen probe 13 are both connected with a display table, and the data detected by the solid content probe 12 and the dissolved oxygen probe 13 inside the biochemical pool 8 can be checked through the display table. The solid content probe 12 and the dissolved oxygen probe 13 are both electrically connected with the control cabinet 11 through communication cables, and the solid content probe 12 and the dissolved oxygen probe 13 transmit a solid content signal and an oxygen content signal to the control cabinet 11. In addition, the stirring electric valve 4 on the stirring gas main pipe 51 is electrically connected with the control cabinet 11 through a communication cable, the aeration electric valve 3 on the aeration main pipe 61 is electrically connected with the control cabinet 11 through a communication cable, and the control cabinet 11 controls the opening and closing of the stirring electric valve 4 and the aeration electric valve 3 through the received solid content rate signal and the received oxygen content signal, so as to control the aeration process and the stirring process. Illustratively, the control cabinet 11 is a PLC control cabinet. Preferably, the fan 1 is provided with an adjusting switch, the adjusting switch is connected with the control cabinet 11 through a cable, and the control cabinet 11 adjusts the frequency of the fan 1 through the adjusting switch.

Referring to fig. 4, a schematic diagram of the control logic of the control cabinet 11 is shown, and the operation of the control cabinet 11 will be described in an exemplary manner with reference to fig. 4.

First, preset values of the solid content and the oxygen content need to be set. In the operation process, the solid content rate probe 12 (TS detector) and the oxygen content probe (DO detector) can transmit the real-time detected solid content rate and oxygen content of the sewage in the biochemical pool 8 to the control cabinet 11. The control cabinet 11 will compare the real-time detection result with the preset value. And the aeration process in the aerobic stage and the stirring process in the anoxic stage are respectively controlled. After the operation time t1 of the fan 1, the control cabinet 11 compares the preset values of the solid content and the oxygen content with the actual measured values: if the measured value is within +/-10% of the preset value, maintaining the existing operating parameters, otherwise, controlling the following steps:

1. in the aerobic stage, when the measured value of the dissolved oxygen is lower than the preset value of 10%, the control cabinet 11 controls the regulating switch of the fan 1 to increase the frequency of the fan 1. The air supply amount in the air supply pipeline is increased by increasing the frequency of the Roots blower, and the air circulation speed in the aeration pipeline 6 and the aeration head 10 is increased, so that the aeration amount of the aeration head 10 is increased. The frequency of the fan 1 is adjusted to increase by 5% and the operation is continued until the measured value of the dissolved oxygen meets the requirement. If the measured value of dissolved oxygen is higher than the preset value by 10%, the aeration amount is decreased by decreasing the frequency of the fan 1 to decrease the amount of air supplied per unit time. If the dissolved oxygen still cannot reach the preset value after the roots blower reaches the maximum frequency, the blockage of the aerator 10 or the failure of the blower 1 is considered.

2. In the anoxic stage, when the solid content probe 12 detects that the solid content of the sewage in the biochemical tank 8 is lower than the preset value by 10%, the stirring interval time is reduced by 5min, then the solid content is detected again after the running time T2 until the solid content reaches the preset value, if the solid content still cannot meet the requirement after the stirring time interval is adjusted to be smaller than T (T is the preset minimum stirring time interval), the stirring interval is stopped to be adjusted, the frequency of the Roots blower is increased by 5% through the adjusting switch, the solid content is detected again after the running time T3, if the difference between the preset value and the preset value is within 10% of the preset value, the parameter adjustment is stopped, and if the difference between the preset value and the preset value is not adjusted until the requirement is met, the frequency of the blower 1 is continuously adjusted. And if the solid content exceeds the preset value by 10%, increasing the stirring time interval by 5min, and detecting again after the running time t 2. If the requirement is not met, the frequency of the fan 1 is reduced by 5%, and the solid content rate value is detected again after the operation time t 3. Similarly, if the dissolved oxygen still does not reach the preset value after the maximum frequency of the blower 1 is reached, it is necessary to consider that the stirring gas pipe 5 is blocked or the blower 1 fails.

To sum up, the aeration stirring integrated device that this application embodiment provided sets up rabbling mechanism and aeration mechanism as an organic whole, carries out the air feed through same fan 1, carries out aeration and stirring respectively in good oxygen stage and oxygen deficiency stage, has improved work efficiency, has saved equipment cost and maintenance cost.
