Problems solved by technology

[0003] The inventor noticed that the liquid level of the biochemical pool is higher than the liquid level of the regulating pool in most cases. According to the principle of fluid mechanics, the fluid tends to flow from a place with high pressure to a place with low pressure. Therefore, in the method of the related art, When the air is supplied, it is easy to cause the gas to flow concentratedly to the regulating tank with low pressure, resulting in the unstable gas supply of the biochemical tank

Abstract

The invention provides an air supply control method, method and device for a wastewater station, and relates to the technical field of industrial wastewater treatment. The wastewater station comprises an adjusting tank and a biochemical tank, and a first air duct communicated with the adjusting tank and a second air duct communicated with the biochemical tank are connected in parallel. The system comprises: a liquid level sensor configured to collect liquid level information of the adjusting tank; the flow meter is configured to collect air volume information of the first air duct; the control valve is arranged in the first air duct; the controller is configured to control the opening degree of the control valve to be gradually increased under the condition that the liquid level, determined according to the liquid level information, of the adjusting tank is higher than a first preset liquid level, so that air from the fan enters the adjusting tank and the biochemical tank through the first air duct and the second air duct respectively; and under the condition that the air volume, determined according to the air volume information, of the first air duct reaches the preset air volume, the opening degree of the control valve is controlled to be kept unchanged.

Description

technical field [0001] The disclosure relates to the technical field of industrial wastewater treatment, in particular to an air supply control system, method and device for a wastewater station. Background technique [0002] In consideration of energy saving and consumption reduction, in related technologies, the air supply pipes of the biochemical pool and the regulating pool of the wastewater station can be connected in parallel, so that air can be supplied to the biochemical pool and the regulating pool at the same time. Contents of the invention [0003] The inventor noticed that the liquid level of the biochemical pool is higher than the liquid level of the regulating pool in most cases. According to the principle of fluid mechanics, the fluid tends to flow from a place with high pressure to a place with low pressure. Therefore, in the method of the related art, When the air is supplied, it is easy to cause the gas to flow concentratedly to the regulating tank with l...
