Background

In the papermaking industry, a large amount of wastewater is generated in pulping, pulp washing and papermaking processes in the papermaking process. At present, biological degradation or chemical agent treatment is mostly adopted in a treatment method aiming at papermaking wastewater, and organic substances and tiny suspended matters in the wastewater are eliminated through the degradation of biological enzymes and biological fungi or the flocculation and sedimentation of chemical agents. The biological method adopts a process of combining aerobic treatment and anaerobic treatment, so that the dissolution of oxygen in the wastewater needs to be enhanced by adopting an aeration mode. At present to the aeration of papermaking waste water, the mode that adopts aeration head, aeration pipe or aeration dish usually carries out dissolved oxygen operation, and above-mentioned aeration structure often causes the aeration head to block up because free calcium and short-staple content are more in the papermaking waste water in the use easily, reduces the aeration effect of waste water for waste water.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The aeration device for treating high-concentration paper-making industrial wastewater shown in fig. 1 to 3 comprises a rectangular aeration tank 1, at least one aeration device 2 horizontally arranged at the bottom of the aeration tank 1, and guide column sets 11 with the number matched with that of the aeration devices. In detail, the guide column set comprises two guide columns 111 which are symmetrically arranged and clamp two ends of the aeration device, and is used for limiting the rotation of the aeration device (preventing the aeration device from toppling) and guiding the lifting track of the aeration device. As shown in fig. 3, the detailed structure of the aeration device 2 comprises an aeration pipe group 21 formed by connecting a plurality of aeration heads 211 in series in sequence, and the aeration pipe group is horizontally laid between the guide column groups 11.
