SYSTEM FOR RECOVERING PHOSPHORUS AND NITROGEN INTO WHICH DUAL AIR FLOTATION TYPE CRYSTAL-FORMING VESSEL AND CRYSTAL-RECOVERING APPARATUS CAPABLE OF GRAIN-SIZE SEPARATION ARE INTRODUCED, AND METHOD FOR RECOVERING PHOSPHORUS AND NITROGEN USING SAME

摘要

The present invention relates to a system capable of simultaneously recovering phosphorus and nitrogen by introducing a dual air flotation type crystal-forming vessel for simultaneously providing macro bubbles and micro bubbles and a crystal-recovering apparatus capable of grain-size separation, and a method for recovering phosphorus and nitrogen using the same.
