Firstly, it should be noted that the anaerobic system of the sewage plant is an important functional step in the sewage treatment process, and the operation of the whole plant is related to the sewage treatment efficiency, so the operation efficiency of the anaerobic system is an important index of the sewage treatment operation.
However, in the existing sewage treatment, the production of the sewage is unstable due to the instability of the production of a paper mill, and thus the anaerobic system of the sewage plant is frequently stopped in a planned manner. However, unstable sewage has a great influence on the operation of the anaerobic system for water treatment, and particularly, the anaerobic system has insufficient nutrition and insufficient rising flow rate, so that the anaerobic granular sludge 500 in the anaerobic tower 100 in the anaerobic system sinks and is deposited at the bottom, activity is lost, and when the anaerobic system is restarted, the operation efficiency of the anaerobic system is greatly reduced.
Specifically, the principle of the anaerobic tower 100 is as follows:
Industrial wastewater is most advanced to a mixing area at the bottom end of a reactor, fully mixed with an internal circulating sludge mixed solution of a running water slide pipe, and then fed to a granular sludge expansion bed area for biochemical degradation of ammonia nitrogen, wherein the ammonia nitrogen volume load is very high, and most of the in-water ammonia nitrogen is dissolved to cause a large amount of biogas slurry.
The biogas slurry is collected by a first-stage 3-item separation device. Because the expansion work done to the liquid state in the process of generating the biogas slurry bubbles causes the stripping effect, the mixture of the biogas slurry, the sludge and the water rises to the enterprise separation equipment at the top of the reactor along the biogas slurry lifting pipe, and the biogas slurry is separated from the sludge and guided out.
The sludge mixture enters a transition zone at the bottom end of the reactor along a sludge downslide pipe and is fully mixed with the water to enter a sludge expansion bed area, so that real internal circulation is generated. According to different structures of different ammonia nitrogen loads and different structures of the reactor, the total internal circulation flow can reach 0.5-5 times of the water inlet flow. The waste water after the solution of the expansion bed is partially added into the internal circulation, and the rest of the waste water enters the granular sludge bed area of the fine solution area according to the first-stage 3-item separation equipment to carry out the processes of dissolving residual ammonia nitrogen and producing biogas slurry, thereby improving and ensuring the quality of effluent. Because most ammonia nitrogen is dissolved, the ammonia nitrogen load of the fine solution area is lower and the yield is also lower. The biogas slurry generated in the position is collected by a two-stage three-phase separator, enters a gas-liquid separator according to a gas collecting pipe and is led out to solve the problem of the system. And after the wastewater solved by the fine solving area passes through the effect of the secondary three-phase separator, the supernatant is discharged through the water outlet area, and the granular sludge returns to the sludge bed of the fine solving area.
Therefore, it is necessary to prevent the anaerobic granular sludge 500 from sinking in the anaerobic tower 100, ensure the activity of the anaerobic granular sludge 500, and further improve the operation efficiency of the anaerobic system.
Referring to fig. 1 to 5 of the specification, the present application provides a system for improving anaerobic operation efficiency, comprising:
the anaerobic towers 100 are arranged in an array, wherein the anaerobic towers 100 are used for accommodating anaerobic granular sludge 500;

The anaerobic towers 100 are arranged in a plurality, and a plurality of anaerobic towers 100 are arranged in an array.
The first conveying device 200 is used for connecting and conducting a plurality of anaerobic towers 100 and is used for conveying anaerobic granular sludge 500 in the anaerobic towers 100 to avoid the sedimentation and accumulation of the anaerobic granular sludge 500 in the anaerobic towers 100. Further, since the anaerobic granular sludge 500 sinks to the bottom of the anaerobic tower 100 during the shutdown process, the connection position of the input end of the first conveying apparatus 200 and the anaerobic tower 100 is disposed at the lower part of the anaerobic tower 100, and the connection position of the output end of the first conveying apparatus 200 and the anaerobic tower 100 is also disposed at the lower part of the anaerobic tower 100. That is, the first transporting apparatus 200 connects the lower regions (regions where the anaerobic granular sludge 500 is deposited) of the two anaerobic towers 100.
Specifically, when the amount of sewage to be treated is reduced, a plurality of anaerobic towers 100 are not required to operate synchronously, and part of anaerobic towers 100 stop operating; the first conveying device 200 may be started at preset time intervals, and the anaerobic granular sludge 500 in one anaerobic tower 100 is transferred to another anaerobic tower 100, so as to achieve the effect of turning over the anaerobic granular sludge 500, thereby increasing the contact area of the anaerobic granular sludge 500 and avoiding the deactivation of the anaerobic granular sludge 500.
Of course, in other embodiments, when the amount of sewage to be treated increases again, the first conveying apparatus 200 may be started in advance to transfer the anaerobic granular sludge 500 in one anaerobic tower 100 to another anaerobic tower 100, so as to achieve the effect of rising the anaerobic granular sludge 500, and thus activate the activity of the anaerobic granular sludge 500 in advance.
If the anaerobic granular sludge 500 in one of the anaerobic towers 100 is excessive, the anaerobic towers 100 can be manually started to transfer the excessive anaerobic granular sludge 500 into the anaerobic towers 100 with less anaerobic granular sludge 500.

When both the first conveying device 200 and the second conveying device 300 are opened, the environments in the two anaerobic towers 100 form convection and tumble, so that the contact area of the anaerobic granular sludge 500 is increased, the anaerobic granular sludge 500 is activated rapidly, and the anaerobic granular sludge 500 is prevented from sinking.
To further enhance the effect of the rising and convection of the anaerobic granular sludge 500, according to some embodiments of the present application, referring to fig. 1 to 2 and 4 to 5 of the present application, the input end of the second conveying apparatus 300 is disposed at the bottom of the anaerobic tower 100, and the output end of the second conveying apparatus 300 is disposed at the bottom of the anaerobic tower 100.
When the anaerobic granular sludge 500 is pumped away from the bottom, the anaerobic granular sludge 500 above will move downwards, and new anaerobic granular sludge 500 will enter the anaerobic tower 100 from the side wall at a high speed, so that the anaerobic granular sludge 500 in the anaerobic tower 100 is continuously moved and turned over, and the contact area of the anaerobic granular sludge 500 is further increased. When the anaerobic granular sludge 500 is injected into the anaerobic tower 100 from the bottom, the anaerobic granular sludge 500 conveyed by the second conveying apparatus 300 will jack up the anaerobic granular sludge 500 originally placed at the bottom of the anaerobic tower 100 due to a certain speed driven by the second conveying apparatus 300, so as to realize the tumbling of the anaerobic tower 100. Further, the two anaerobic towers 100 can realize the tumbling of the anaerobic granular sludge 500 by the arrangement of the first conveying apparatus 200 and the second conveying apparatus 300.
