Abstract

The invention discloses an integrated cyclone air flotation device which comprises integrated outer cylinder and inner cylinder, wherein the inner cylinder is arranged in the outer cylinder; an annular cavity is formed between the outer cylinder and the inner cylinder; the annular cavity is communicated with a water inlet and a gas inlet of the outer cylinder; a gas-water releaser for transforming a gas-water mixture in the inner cylinder into microbubbles is arranged in the annular cavity; a residue collection tank or an oil collection tank for collecting the floating residue or floating oil gathered on the annular cavity is arranged at the upper end of the inner cylinder; a residue discharge pipe or an oil discharge pipe is arranged in the inner cylinder; and the upper end of the residue discharge pipe or the oil discharge pipe is communicated with the residue collection tank or the oil collection tank, and the lower end is communicated with a residue discharge port of the outer cylinder. The invention also discloses a sewage treatment method. The integrated cyclone air flotation device disclosed by the invention has simple structure and high integration degree and can efficiently realize solid-liquid separation and wastewater purification while the energy consumption is low.

Description

technical field [0001] The invention specifically relates to an integrated swirling air flotation device and a sewage treatment method, belonging to the technical field of environmental protection. Background technique [0002] With the rapid development of the national economy and the improvement of people's consumption levels, the discharge of urban sewage and industrial wastewater is increasing day by day, especially the growth rate of the discharge of major pollutants in industrial wastewater has exceeded the growth rate of the gross national product, destroying the The balance between national economic growth and ecological environment protection restricts the development of industrial civilization. According to statistics, high-pollution and high-discharge industries, such as chemical industry, papermaking, petroleum, and electric power, discharge 40 billion tons of wastewater into natural water bodies every year. If the discharge continues to grow without treatment, t...
