  Abstract:

  Municipal sludge was pretreated by hydrothermal carbonization method, and phosphorous was extracted from the sludge hydrothermal carbon by sulfuric acid method. Considering the release of calcium, iron and aluminum, the effects of sulfuric acid concentration, leaching time and liquid-solid ratio on the phosphorus extraction performance was investigated. The forms of phosphorus in hydrothermal carbon were mainly Ca-P and Mg-P, which were conducive to the extraction and utilization of phosphorus. The leaching rates of phosphorus and related metals showed an overall increasing trend with the increase of sulfuric acid concentration. Long leaching time led to the formation of calcium sulfate crystals in the solution, and reduced the leaching rates of phosphorus and calcium. The leaching rates of iron and aluminum increased with the increase of leaching time. However, the leaching time was longer. The liquid-solid ratio affected the leaching performance of phosphorus and related metals by influencing the contact area between hydrothermal carbon and acid. When the sulfuric acid concentration was 0.5 mol/L, leaching time was 120 min and liquid-solid ratio was 50 mL/g, the maximum leaching rate of phosphorus from hydrothermal carbon was 93.8%, and the leaching rates of calcium, iron and aluminum was 70.4%, 54.5% and 65.8%, respectively.
