Problems solved by technology

However, due to the short hydraulic retention time, there will be shedding biofilm in the effluent, and the effect of the sedimentation area of ​​the separator is not ideal. We can only set a sedimentation tank outside the bed to reduce the suspended solids in the effluent

Embodiment Construction

[0010] The present invention is a kind of labyrinth biological carrier separator used for biological fluidized reactor used in airlift reactor, water and gas of general airlift reactor all enter from the bottom of reactor; The biological carrier separator 1 is composed of three layers of interlaced triangular reflective cones 6, installed in the middle of the reactor, the upper part of the reactor is an air flotation separator 2, and the surrounding area of ​​the air flotation separator 2 is a high-efficiency separation zone 3, a labyrinth carrier separator The upper and lower sides of 1 are the reactor buffer zone 4, and the lower part is the fluidized reaction zone 5. The periphery of this zone is an aerobic zone, and the middle part is an anoxic zone. The reflective cone 6 restricts the passage of the fluidized carrier 7, which is used to limit the biological carrier 7 in the suspended fluidized state to the aerobic reaction zone, preventing the biological carrier and the mi...

Abstract

The present invention belongs to sewage treating equipment and technology in environment protection and is one mazy biological carrier separator used for biological fluidizing reactor as one kind of gas stripping reactor. The mazy biological carrier separator is installed in the middle part of the reactor with one air floating separator in the upper part. The mazy biological carrier separator consists of three layers of crossed triangular reflecting cones to prevent carrier from staying on it. Through the air floating separation of suspended solid, air will overflow automatically from the efficient separating area. The said method has raised solid-liquid separating speed and improved separation effect.

Description

technical field [0001] The invention belongs to the field of sewage treatment equipment and technology in environmental protection, and in particular relates to a labyrinth biological carrier separator used in a biological fluidized reactor used in an airlift reactor. Background technique [0002] The internal circulation three-phase biological fluidized bed is a new type of fluidized reactor, which has a series of advantages such as good mixing performance, high mass transfer rate, high sludge concentration and high organic load. In addition, the height-to-diameter ratio of the biological fluidized bed is much larger than that of general wastewater biological treatment structures, and its footprint can be greatly reduced. Due to the above-mentioned characteristics of the aerobic biological fluidized bed, it has great potential for development. At present, various types of aerobic biological fluidized beds have been studied and applied in the field of wastewater treatment. ...
