Description

technical field

[0001] The present invention relates to a sewage treatment device, in particular to a device that organically combines activated sludge biological treatment technology with granulation fluidized bed solid-liquid separation technology, and simultaneously realizes sewage biological treatment and solid-liquid separation in one unit, capable of Efficiently remove suspended solids and organic matter in sewage, and quickly complete solid-liquid separation. The invention is applicable to urban sewage treatment, sewage treatment in living quarters, and industrial wastewater treatment, and is especially suitable for decentralized sewage treatment and reuse. Background technique

[0002] The main removal objects of sewage treatment are organic pollutants and suspended solids (SS) in water. The method of removing organic matter is generally activated sludge method, which uses microorganisms growing in sludge to degrade organic pollutants in water; the method of removin...
