The flow field is reconstructed by mechanical rotation, and the kinetic energy of the fluid is replaced by centrifugal shear, thereby improving the separation efficiency, reducing the circulation flow rate, and reducing the power consumption of the pump. The shear force of the waste liquid is perpendicular to the membrane surface, which improves the efficiency of stripping the contamination layer. The waste liquid flowing through the liquid inlet assembly 45 enters the inner cavity of the fixed tube 42, and is driven by the motor 44 to rotate the driving gear 441, so that the driving gear 441 rotates the ceramic membrane assembly 491 through the meshing gear ring 493, so that the liquid entering the ceramic membrane assembly 491 no longer flows horizontally, but flows tangentially, thereby increasing the shear force of the waste liquid; Next, through the mutual cooperation between the water pump 47, delivery pipe assembly 46, filter assembly 49, nozzle 48, motor 44 and drive gear 441, the device can make the ceramic membrane assembly 491 filter and clean at the same time, reduce the probability of clogging of the ceramic membrane assembly 491, and improve the filtration efficiency of the device; the waste water is extracted from the inner cavity of the water tank 41 by the water pump 47 and delivered to the nozzle 48 through the delivery pipe assembly 46, and sprayed to the surface of the rotating ceramic membrane assembly 491 through the nozzle 48, so as to achieve the purpose of filtering and cleaning the ceramic membrane assembly 491.

Any technician familiar with this technical field, within the technical scope disclosed by the present invention, can make equivalent replacements or changes to a high-ammonia nitrogen wastewater resource recovery device and its inventive concept according to the technology of the present invention, which should be covered by the scope of protection of the present invention.
