/ Biological nutrient removal process increased the removal efficiency of nitrogen phosphorus and enhancing the hydraulic capacity through the refining unit process of the mixed liquor suspended solid in return line
The present invention relates to a biological nutrient desalination / wastewater treatment method and a treatment system thereof, in which an activated sludge refining system is provided in a return line to increase nitrogen removal efficiency and treatment capacity. In the internal return line, And the sludge and desorption liquid are separated from the sludge and the desorption liquid to supply the desorption liquid to the anoxic tank. In the outer conveyance line, the sludge and desorption liquid are separated from the desorption liquid supplied from the sedimentation tank, Tearing section is provided. In addition, the inner transfer line between the first desorption unit and the non-oxygen storage tank is provided with a desorption unit for removing bubbles contained in the desorption liquid and vibrating the water. The desorption unit is provided in a water tank for entering and leaving the desorption liquid, And an ultrasonic wave generator that vibrates the water. Therefore, the effluent of the environment useful for the anoxic tank is supplied by the first desorbing portion, and the sludge useful for the anaerobic tank is supplied by the second desorbing portion. Therefore, the effect of the sewage treatment is increased, and the water tank is vibrated, Can be smoothly discharged to the outside.
