- W2132776278 abstract "Ozone can be used in treatment of industrial recycling cooling water. In order to guide practice more efficiently, the dynamics equation of ozone decomposition in recycling cooling water was established. The research deducted mathematical model of the decomposition. It is that: -d[O <sub xmlns:mml=http://www.w3.org/1998/Math/MathML xmlns:xlink=http://www.w3.org/1999/xlink>3</sub> ]/[O <sub xmlns:mml=http://www.w3.org/1998/Math/MathML xmlns:xlink=http://www.w3.org/1999/xlink>3</sub> ]dt = k' <sub xmlns:mml=http://www.w3.org/1998/Math/MathML xmlns:xlink=http://www.w3.org/1999/xlink>1</sub> [OH <sup xmlns:mml=http://www.w3.org/1998/Math/MathML xmlns:xlink=http://www.w3.org/1999/xlink>-</sup> ] + k <sub xmlns:mml=http://www.w3.org/1998/Math/MathML xmlns:xlink=http://www.w3.org/1999/xlink>2</sub> [OH <sup xmlns:mml=http://www.w3.org/1998/Math/MathML xmlns:xlink=http://www.w3.org/1999/xlink>-</sup> ] <sup xmlns:mml=http://www.w3.org/1998/Math/MathML xmlns:xlink=http://www.w3.org/1999/xlink>x</sup> [COD <sub xmlns:mml=http://www.w3.org/1998/Math/MathML xmlns:xlink=http://www.w3.org/1999/xlink>Cr</sub> ]. Then experiment water of different concentrations multiple was confected, adjusted alkalinty with NaHCO <sub xmlns:mml=http://www.w3.org/1998/Math/MathML xmlns:xlink=http://www.w3.org/1999/xlink>3</sub> , ozone of different concentrations was led into, ozone decomposition rate was mensurated. When pH was 8.0, 8.5, 9.0, 9.5 and COD <sub xmlns:mml=http://www.w3.org/1998/Math/MathML xmlns:xlink=http://www.w3.org/1999/xlink>Cr</sub> was 1, 3, 6, 7 mg/L, the interrelated data was determined. The dynamics equation of ozone decomposition at the experimental condition is: -d[O <sub xmlns:mml=http://www.w3.org/1998/Math/MathML xmlns:xlink=http://www.w3.org/1999/xlink>3</sub> ]/[O <sub xmlns:mml=http://www.w3.org/1998/Math/MathML xmlns:xlink=http://www.w3.org/1999/xlink>3</sub> ]dt = 75460times[OH <sup xmlns:mml=http://www.w3.org/1998/Math/MathML xmlns:xlink=http://www.w3.org/1999/xlink>-</sup> ] +4.990times[OH <sup xmlns:mml=http://www.w3.org/1998/Math/MathML xmlns:xlink=http://www.w3.org/1999/xlink>-</sup> ] <sup xmlns:mml=http://www.w3.org/1998/Math/MathML xmlns:xlink=http://www.w3.org/1999/xlink>0.228</sup> [COD <sub xmlns:mml=http://www.w3.org/1998/Math/MathML xmlns:xlink=http://www.w3.org/1999/xlink>Cr</sub> ]. Analysing the mathetics model, we can see that affecting decomposition factors are not only [OH <sup xmlns:mml=http://www.w3.org/1998/Math/MathML xmlns:xlink=http://www.w3.org/1999/xlink>-</sup> ], but also COD <sub xmlns:mml=http://www.w3.org/1998/Math/MathML xmlns:xlink=http://www.w3.org/1999/xlink>Cr</sub> in water, include the microbe, organic compound, reductive inorganic compound and so on. In practical using, it should monitor water quality continuously or intermittently, adjust ozone quantity according to the pH and COD <sub xmlns:mml=http://www.w3.org/1998/Math/MathML xmlns:xlink=http://www.w3.org/1999/xlink>Cr</sub> in the water, at the same time, it also should control COD <sub xmlns:mml=http://www.w3.org/1998/Math/MathML xmlns:xlink=http://www.w3.org/1999/xlink>Cr</sub> of the system so that it can ensure treatment effect." @default.
