Description
technical field [0001] The invention relates to the technical field of environmental protection, in particular to a cyclone sewage separation device and a sewage treatment method. 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, the natural environ...
