Problems solved by technology
Therefore, the applicant considers to directly discharge the soluble organic matter in the aquaculture tail water into the nitrification reaction biofilter, the COD reaction biofilter and the denitrification reaction biofilter for treatment. And the temperature changes in summer and winter will lead to changes in the microbial activity in the nitrification reaction biofilter, COD reaction biofilter and denitrification reaction biofilter, so the soluble organic matter is directly discharged into the nitrification reaction biofilter, COD reaction biofiltration Pond and denitrification biofilter may cause the content of soluble organic matter to exceed the treatment upper limit of nitrification biofilter, COD reaction biofilter and denitrification biofilter, and the treated tail water still does not meet the requirements for reuse

The invention discloses a treatment device for recycling breeding tail water, which comprises a water pump, a filtering device and a protein separator which are connected in sequence, the water pump comprises a motor and a pump chamber, a protein liquid mixing pipeline is arranged between a protein liquid collecting cavity and a liquid outlet pipeline of the protein separator, and a one-way valve is arranged on the protein liquid mixing pipeline. A rotating drum with uniformly distributed blades on the inner wall is rotatably arranged on the protein liquid mixing pipeline, a first chain wheel rotatably sleeves the periphery of the rotating drum, a first cavity is formed in the first chain wheel, a heat expansion and cold contraction medium is arranged in the first cavity, a first guide hole is inwards formed in the first cavity, and a first ejector rod is arranged in the first guide hole; a first telescopic rod is arranged at the end of the first ejector rod, a first friction plate is arranged on the first telescopic rod, a first spring is arranged between the first ejector rod and the first friction plate, and the first chain wheel is in transmission with an output shaft of the motor through a chain. According to the treatment device, soluble organic matters can be proportionally mixed into culture tail water according to microbial activity.
Description
Technical field [0001] The present invention is the technology field of breeding tailwater treatment device. It is specifically a processing device for recycling of farming tailwater. Background technique [0002] Traditional aquaculture is generally discharged directly by breeding tail water, while the farming tail water contains a large amount of breeding organic feces, unpaid feed, etc. If it is discharged directly to the surrounding waters, it will endanger the ecology of the surrounding waters. [0003] With the improvement of people's requirements for environmental protection, the treatment of farming tailwater has also gradually received a wide consensus. For example, CN112209573A disclosed a breeding tailwater treatment system. The breeding tailwater treatment system includes primary filter device, protein separator, first -nitrification reaction biological filter, first COD reaction biological filter, second nitrification reaction biological filter pool , Nitrostatic rea...
