Detailed Description
When the aeration device in the prior art is operated in daily life, the aeration rate is generally required to be adjusted by manually adjusting the frequency of the fan and the opening of the valve according to the sewage quantity, the sewage quality and the measured dissolved oxygen value in the sewage. Because of different actual treatment capacities, the liquid level heights of the wastewater treatment production lines are difficult to be completely consistent, and the water pressure at the outlet of the air pipe is changed due to the change of the liquid level heights, so that the air flow rate of each aeration point is different, and finally, the dissolved oxygen is suddenly high or low. Too high dissolved oxygen not only reduces the sewage treatment effect, but also wastes electric energy; and too low dissolved oxygen can not achieve the effect of purifying the wastewater. In order to cope with the sudden high and low change of the dissolved oxygen, operators need to frequently and manually adjust the air supply quantity of the fan and the air valves of each production line, and the method not only needs to consume a great deal of labor cost and time cost, but also has the problem of time lag.
