Background
A fluidized bed bioreactor is a simple, robust, flexible and compact process for the treatment of wastewater. MBBR in different configurations has been successfully used to remove BOD5Oxidizing ammonia nitrogen and removing nitrogen. The MBBR process uses special bio-carriers as biofilm carriers, which can be suspended in the reactor by aeration turbulence, liquid reflux or mechanical mixing. The biological carrier used at present is mainly hollow cylinder, the diameter of the biological carrier is about 25-27mm generally, and the thickness of the biological carrier is about 10 mm. In the production process, the bio-carrier mainly goes through the processes of heating, extruding, passing through a die, shaping, cooling, drawing and cutting, and the thickness of the bio-carrier is mainly controlled by the drawing speed and the cutting speed.
However, in the actual production process, problems such as 'slipping' of the traction equipment, blockage of a die gap, water inflow of the sizing equipment and the like often occur, which causes temporary interruption of the production line of the continuous production, but at the moment, the cutting equipment still runs, so that at the beginning of the production line interruption, the cutting equipment can cut products with relatively thin thickness and incomplete shapes. The products are not enough in thickness and size and incomplete in shape, and easily pass through the biological carrier interception net in the actual use process, enter a subsequent treatment system, block subsequent equipment and influence the normal operation of the process. Therefore, how to realize the screening of the unqualified biological vectors has important significance.
In response to the problems in the related art, we propose a screening apparatus for biological vectors.
