an experimental study on the precipitation of calcium nitrite derived from wastewater treatment by oxidation of NOx and SO2 with ozone was performed. The effects of reaction temperature
reactant concentration
turbulence intensity on calcium nitrite precipitation efficiency were investigated by the variable-controlled method. Reaction temperature strongly influenced precipitation efficiency and optimal temperature was 80℃. Both increasing reactant concentration and turbulence intensity in the reaction process could enhance precipitation efficiency. Because double-salt precipitation was accompanied by separation of calcium hydroxide
precipitation efficiency could be improved by altering the separation conditions of calcium hydroxide.
