Optimum Reaction

Supercritical water oxidation process can effectively degrade the total nitrogen in municipal sludge. In order to obtain the optimum parameters of municipal sludge treated by supercritical water oxidation, this article selected the total nitrogen removal rate as the evaluation value, and used response surface methodology to optimize the parameters of sludge treatment by supercritical water oxidation, the parameters including temperature, pressure, residence time and oxidation coefficient. The results show that the reaction temperature, pressure and residence time exist interaction, and the influence degree of parameters is: pressure > reaction temperature > reaction retention time; The optimum reaction conditions are as follows: reaction temperature 539 °C, pressure 27 MPa, residence time 434 s, and oxidation coefficient 2.16, under these conditions, the total nitrogen decreasing efficiency can reach 74.12%.
