Abstract

The invention discloses a bio-contact oxidation tank. The bio-contact oxidation tank comprises a tank body, the tank body comprises a biomembrane filling material, an aeration apparatus, and a sewage water inlet, and a sewage outlet channel, a diversion channel is arranged in the tank body, the diversion channel and the biomembrane filling material are isolated by a first diversion wall, the aeration apparatus and the sewage water inlet are positioned at the bottom of the diversion channel, a stratosphere is arranged at top of the diversion channel, the stratosphere is communicated with the diversion channel and the biomembrane filling material, a stirring device is arranged on the tank body, and several stirring vanes are fixedly arranged on a transmission shaft of the stirring device and are extended into the diversion channel. The bio-contact oxidation tank has good foam diffusivity, oxygen can be uniformly distributed in the tank body, the equipment reconstruction cost is low, and the failure rate is low.

Description

technical field [0001] The invention relates to a biological contact oxidation pond, which belongs to the field of sewage treatment. Background technique [0002] Modern sewage treatment technology can be divided into physical treatment, chemical treatment and biological treatment according to the treatment method. Physical treatment method, also known as mechanical treatment method. It is mainly used to separate suspended substances in wastewater. The biggest advantage of this method is that it is simple, easy to implement, effective, and very economical. Commonly used physical treatment methods are: gravity separation method, centrifugal separation method, filtration method and evaporation crystallization method. The main target of chemical treatment is soluble or colloidal pollutants in wastewater. It can not only separate polluting substances from water, but also change some polluting substances and organic substances, so it can achieve a higher degree of purificatio...
