Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a biochemical tower equipped with a high-efficiency cyclone aerator and a settling tank, which can be applied to the biochemical treatment of various sewage and an application method thereof. Background technique [0002] Biological treatment is the use of microorganisms to decompose organic pollutants in sewage into carbon dioxide and water under aerobic conditions to achieve the purpose of purifying sewage. It has the advantages of simple treatment facilities, good effluent quality, low treatment cost, and environmental friendliness. It is the most commonly used sewage treatment process. The main facility of biological treatment is a biochemical tank. The traditional biochemical tank adopts a reinforced concrete structure, and the effective water depth is generally 5 to 6 meters. Due to the low rate of biodegradation reaction, the hydraulic retention time of sewage in t...
