Abstract

The invention discloses a circular-oxygenation biochemical device which comprises a biochemical reaction tank, wherein the biochemical reaction tank is provided with a water inlet, a decanting device and a sludge discharge port, and an aerating system is laid on the bottom; a guide system and a grid plate are fixedly arranged in the biochemical reaction tank; the guide system comprises suspended guide plates and a top hood; the guide plates are arranged along the upstream and downstream direction; the two guide plates in each pair are faced with each other, and the distance becomes larger from top to bottom; the cross section of the top hood is in an inverted V shape, the top hood is covered above the guide plates, and the top end of each guide plate is positioned in the lower edge of the top hood; the grid plate is arranged in the direction perpendicular to the upstream and downstream direction, and positioned on the downstream of the guide plates; and sewage enters the biochemical reaction tank through the water inlet and is aerated by the aerating system to obtain the mixed solution, the mixed solution is stood to precipitate, and the upper water is flocculated by the regenerant on the grid plate and discharged out of the biochemical reaction tank through the decanting device. The circular-oxygenation biochemical device has the advantages of more thorough biochemical reaction, more sufficient precipitation and higher effluent water quality.

Description

technical field [0001] The invention belongs to the field of sewage treatment, and in particular relates to a circulating oxygenation biochemical device. Background technique [0002] The current conventional treatment methods for rural domestic sewage include biological contact oxidation + constructed wetland, biological turntable + constructed wetland, trickling filter + constructed wetland, biogas digester + drip aeration + constructed wetland, membrane bioreactor (MBR), aerated biological Filter (BAF) + constructed wetland, etc. These treatment processes basically use the physiological characteristics of microorganisms and artificial engineering technology measures, and adopt advanced treatment of constructed wetlands. Constructed wetlands occupy a large area, are easily affected by pests and diseases, are troublesome to manage, labor-intensive to regenerate fillers, and the biochemical process of the ecosystem is extremely unstable, resulting in poor sustainable perfor...
