THE FIELD STABILIZING METHOD OF CONTAMINATED SOIL USING CA-CP SOIL STABILIZER

摘要

PURPOSE: A calcium citrate phosphate soil stabilizer, a method for manufacturing the same, and a method for stabilizing polluted soil using the same are provided to stabilize heavy metal in the polluted soil by expediting the activity of microorganism in the soil. CONSTITUTION: A calcium citrate phosphate soil stabilizer includes 24~35 weight% of calcium chloride, 15~20 weight% of sodium phosphate, 0.5~1 weight% of ammonium nitrate, and 45~60 weight% of sodium citrate, with respect to 100 weight% of the stabilizer. Calcium citrate is formed by mixing calcium chloride and sodium citrate. Ammonium nitrate is mixed in the mixed calcium chloride and sodium citrate solution. Sodium phosphate is mixed in the mixed calcium chloride, sodium citrate, and ammonium nitrate solution.
