The present invention relates to a phosphorus returning system for reducing the load in current water: which mixes the current water of digested supernatant and desorption filtrate treated in a wastewater treatment system with magnesium hydroxide and caustic soda (sodium hydroxide) in a line mixer for easily producing phosphorus precipitates in the current water, adjusting the pH concentration by purifying the current water, and precipitating and removing phosphorus in the current water in an optimum condition inside a phosphorus returning reaction tank; remarkably reduces the phosphorus and nitrogen load on the current water inside the phosphorus returning reaction tank; and stirs the current water and a coagulant for coagulating and smoothly precipitating using bubbles generated from a bubble spraying port of the phosphorus returning reaction tank. |
