Abstract

The invention discloses an activated sludge biomembrane composite sewage treatment device, which comprises a stirrer, a biological carrier component and a biological carrier bracket. The stirrer is asubmersible stirrer, and the stirrer is arranged at the bottom of a sewage tank. the biological carrier component is fixed on the biological carrier bracket at an interval of 150 mm-220 mm. The biological carrier bracket is arranged in the sewage tank. The top of the biological carrier bracket is 1.0 m-1.4 m away from the top of the sewage tank, and the bottom of the biological carrier bracket is0.6 m-1.0 m away from the bottom of the sewage tank. Under the action of the stirrer, on the one hand, the activated sludge is suspended in the sewage, and on the other hand, the activated sludge canbe filled into gaps of the biological carrier to form a biomembrane by layer-by-layer covering, so that the biomembrane and the suspended activated sludge coexist in the sewage, and the impact load resistance and the pollutant degradation capability of the device are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to an activated sludge biofilm composite sewage treatment device and a treatment method. Background technique [0002] Biological sewage treatment methods include activated sludge method and biofilm method. [0003] Activated sludge method: refers to the method of mixing activated sludge and sewage, maintaining a certain concentration of dissolved oxygen and suspended microorganisms in the reactor through aeration and stirring, and using the metabolism of microorganisms to remove organic pollutants in water. Divided into anaerobic activated sludge method, anoxic activated sludge method and aerobic activated sludge method. Anaerobic activated sludge method: the dissolved oxygen mass concentration is generally less than 0.2mg / L, and its main functions are hydrolytic acidification, methane production, phosphorus release, etc.; anoxic activated sludge method: the d...
