Problems solved by technology

In addition, the measurement method of the bubble size needs to introduce the water containing the bubbles into the observation tank, and then use the camera method to collect image information for data analysis. The obtained bubble size is relatively accurate, but it cannot reflect the bubble size in the contact area in time. Limited to laboratory research, powerless for real-time monitoring in large-scale industrial applications

Embodiment Construction

[0021] The implementation of the present invention will be described in detail below in conjunction with the drawings and examples.

[0022] like figure 1 As shown, a dynamic observation and control system for air-floating microbubbles, including:

[0023] A bubble dynamic test device composed of a beam transmitter 3, a metering tank 2 and a photodiode receiver 1 arranged in the air flotation area 18; the metering tank 2 is a cuboid with a fixed volume, and the gas produced by passing through a unit volume in a unit time is measured. The pulse signal is used to represent the number of bubbles, and the density of the bubbles can be obtained. If the volume of the contact area is known, the total number of bubbles can be calculated.

[0024] The pressure relief valve gas meter 13 arranged on the pressure tank 19;

[0025] The air flotation gas meter 10 and the oxidation gas meter 8 are respectively installed on the two paths separated from the outlet of the ozone generator 9; t...

Abstract

The invention discloses a dynamic observation and regulating system for air floatation microbubbles. The dynamic observation and regulating system has the advantages that the light barrier type particle counting principle is utilized to monitor bubble size in real time, and the problem of time lag of traditional bubble size measuring is solved; secondary regulating of the bubble size is achieved by a bubble regulating plate, and the limitation of excessively small regulating range is solved; real-time and accurate measuring of the bubbles is achieved, and the flexibility of air floatation treatment is increased.

Description

technical field [0001] The invention belongs to the technical field of advanced sewage treatment, and in particular relates to a dynamic observation and control system for air flotation microbubbles. Background technique [0002] As an advanced treatment process for urban sewage, the ozone air flotation process combines ozone oxidation technology and air flotation separation technology to simultaneously complete demulsification, flocculation, solid-liquid separation, color removal, smell, taste, disinfection, etc. in one operating unit. multiple processes. The size of the bubbles in the air flotation process is an important factor affecting the treatment effect of the process, so the effective regulation of the size of the bubbles in the process operation is the key to improving the treatment efficiency. At present, the commonly used control method is to adjust the dissolved air pressure, which can only reflect the size of the bubbles through the size of the air pressure, b...
