Beschreibung
Zusammenfassung:	The invention discloses a multi-stage sewage treatment device, and belongs to the technical field of environmental protection. The device comprises a filtering part, a biodegradation box, an aerobic biological part, an anaerobic biological part and a purifying part, the filtering part is connected with the biodegradation box through a pipeline, the aerobic biological part and the anaerobic biological part are both arranged in the biodegradation box, the aerobic biological part is located above the anaerobic biological part, and the purifying part is located above the anaerobic biological part. The purification part is connected with the biodegradation box through a pipeline. According to the device, the pressure on sewage is changed by water-gas conversion in the filtering part, the vertical separation of filtered water and sludge is accelerated, and the aerobic biological part is conveyed by a spiral blade, so that aerobic microorganisms are quickly proliferated in eddy current rich in nutrient substances an
