Problems solved by technology

However, in order to solve the shortcomings of unbalanced flow and poor mass transfer capacity in the reactor, it is necessary to increase power consumption to increase the liquid flow rate in the reactor. In fact, the energy saving effect is not obvious.

Embodiment Construction

[0021] exist figure 1 In the process, the gas from the oxygen or air supply equipment passes through the gas filter (2) to remove fine particles in the gas, and after the pressure adjustment of the pressure regulating device (3) before the gas supply, it enters the aerobic pool installed in the aerobic pool ( 1) The microporous membrane oxygenation component (5) inside performs bubbling oxygenation. As the air pressure increases, oxygenation enters the process of bubble generation and expansion, and the bubbles are generated on the surface of the microporous membrane and continue to expand. Thereafter, the pressure of the air supply is used to maintain the expansion state of the bubbles, but most of the bubbles do not leave the surface of the microporous membrane, which is the bubble maintenance process. After the bubble maintenance process is carried out for a period of time, the oxygen content in the gas decreases and the carbon dioxide content increases. At this time, the ...

Abstract

A device for oxygenating water is provided. Characteristics of a microporous membrane are utilized to increase the contact area and contact time of gas and water during aeration. The oxygen utilization rate for water oxygenating is increased. Aeration power consumption is saved. The oxygenating capability is high and can meet requirements of high oxygen load in unit area.

Description

technical field [0001] The invention relates to a device for adding oxygen to water, in particular to providing dissolved oxygen for microorganisms in the process of sewage treatment. Background technique [0002] The aerobic biochemical treatment process is the main process of sewage treatment. The microbial population uses the dissolved oxygen in the water to degrade the organic pollutants in the sewage. The oxygen utilization rate of the process aeration equipment and the level of sludge concentration affect the land occupation, project investment and operation cost of the sewage treatment plant. The larger the bubbles generated by the aeration equipment, the smaller the relative gas-liquid two-phase contact area at the same aeration rate, the relative time that the bubbles stay in the liquid phase is short, and most of the oxygen escapes from the water surface with the bubbles. In recent years, in the field of sewage treatment, efforts have been made to reduce the diame...
