Abstract

The invention discloses a dynamic adjustable river-lake oxygenation flow-pushing method and device, and relates to the technical field of the river control. The device comprises a submersible sewage pump, an ejector, a micro-nano bubble generator, a throat hose, a fluid flowmeter, a gas flowmeter and solenoid valves. The submersible sewage pump is connected with the ejector through the first solenoid valve. The ejector is connected with the throat hose. The throat hose is further provided with a first branch pipe and a second branch pipe. The first branch pipe is connected with the micro-nanobubble generator. The second branch pipe is communicated with air. The first branch pipe is provided with the second solenoid valve and the fluid flowmeter which are successively connected. The fluidflowmeter is connected with the micro-nano bubble generator. The second branch pipe is provided with the third solenoid valve and the gas flowmeter which are successively connected. The gas flowmeteris communicated with the air. The device is capable of, according to dissolved oxygen concentration of rivers and lakes, dynamically adjusting a bubble density and a bubble size, changing the flow pushing effect of the device, thereby more effectively realizing an application in the river and lake treatment.

Description

technical field [0001] The invention relates to the technical field of river management, in particular to a method and device for dynamically adjustable oxygenation and pushing of rivers and lakes. Background technique [0002] Due to its unique performance advantages, micro-nano bubbles are mainly used in the fields of oxygenation of black and odorous water, air flotation water purification, ozone disinfection, medical beauty, aquaculture and other fields, with a broad market space. In the treatment of rivers and lakes, the micro-nano bubbles can stay in the water for a long time due to the small particle size of the bubbles, so as to effectively remove organic matter, algae and other pollutants in the rivers and lakes, and realize the purification of rivers and lakes. [0003] At present, the microbubble generation technologies used in river and lake treatment mainly include dispersed air method, dissolved air release method, etc., but due to the constraints of complex equ...
