in addition, when the blanking rod 43 moves to a certain position, as the blanking rod 43 is of a stepped design, as shown in fig. 6, one end of the blanking rod 43 is of a convex block design, the outer side of the convex block is in contact with the inner wall of the fixed pipe 42, the blanking rod 43 is in sealing connection with the blanking groove 45, at the moment, the additive in the storage tank 41 flows out through a gap between the blanking groove 45 and the blanking rod 43 and is blocked by the convex block, so that the additive amount required to be added can be automatically calculated according to the moving height and the moving distance of the floating plate 39, nutrient substances consumed in the membrane biological reaction tank 2 can be compensated, the microbial environment in the membrane biological reaction tank 2 is suitable, and the sewage treatment efficiency is improved;
the method adopts the moving distance of the floating plate 39 to measure and calculate the sewage filtering amount, so that the sewage amount can be intuitively recorded, the additive amount required for supplementing nutrient substances can be automatically calculated through the sewage amount, on one hand, the workload is saved, the working efficiency is improved, on the other hand, the additive amount variable is automatically controlled through the sewage variable, and the sewage filtering amount is closely related to each other, so that the design is ingenious and convenient;
after sewage is conveyed to the inside of the membrane biological reaction tank 2 through the conveying pipe 37, the floating plate 39 moves reversely, and then the blanking rod 43 is driven to move reversely through a linkage relation, and the blanking rod 43 moves to a certain position, the bump cannot block additives, the additives are added to the inside of the membrane biological reaction tank 2, and nutrient substances consumed by microorganisms are supplemented;
in the process that the floating plate 39 ascends through buoyancy, when the floating plate 39 drives the connecting rod 44 to move, the connecting rod 44 not only drives the blanking rod 43 to move, but also drives the air supply pipe 52 to move, when the air supply pipe 52 moves to a certain position, the communicating groove 55 on the air supply pipe 52 is communicated with the air outlet pipe, at the moment, part of air enters the air supply pipe 52 through the communicating groove 55, enters the blanking rod 43 through the air supply pipe 52, enters the membrane biological reaction tank 2 through the blanking rod 43, oxygen can be supplemented to the membrane biological reaction tank 2, a certain nutrient substance is provided, the living environment of microorganisms is more suitable, and therefore, a certain nutrient substance can be provided for the microorganisms initially before additives are added, and the efficiency of sewage treatment is improved; after the sewage in the membrane biological reaction tank 2 is discharged, when the sewage in the regulating tank 1 enters the membrane biological reaction tank 2, at the moment, the connecting rod 44 moves reversely to seal the communication groove 55 and the air outlet pipe again, and at the moment, the additive is added into the membrane biological reaction tank 2, so that the excessive nutrient substances of microorganisms can be avoided, the growth of the microorganisms cannot be promoted, and the living environment of the microorganisms is influenced;
in addition, after the blower 51 is started, the blower 51 is communicated with the regulating tank 1 through the ventilation pipe 54, so that the air in the regulating tank 1 can be driven to flow, peculiar smell is removed, and a good working environment is provided.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
