Carbon dioxide gas floatation treatment system for coal chemical industrial wastewater

ActiveCN104909420AImprove the separation effectIncreased mixing contact surface
The invention discloses a carbon dioxide gas floatation treatment system for coal chemical industrial wastewater. The carbon dioxide gas floatation treatment system for coal chemical industrial wastewater comprises a conditioner and a gas floatation device, wherein the conditioner takes carbon dioxide as a gas source; and the gas floatation device is connected with the conditioner by a pipeline. According to the invention, by taking original waste carbon dioxide as a gas source, after the carbon dioxide is dissolved in water, wastewater is converted into acidic wastewater, and the PH value of the wastewater is adjusted, so that the original alkali wastewater is converted into acidic wastewater, thereby greatly improving the separation effect of subsequent gas flotation; and because carbon dioxide is taken as a gas source, the increasing of a COD value and the occurrence of bubbles caused by the fact that air as an air source easily oxidizes organic pollutants in wastewater, are avoided, so that the biodegradability of the wastewater is reduced. Because carbon dioxide is difficult to be dissolved in water, the gas source increases the pressure, and a disc-type jet aerator (a patent of our company) is applied for increasing a mixed contact surface, so that an effect of increasing the solubility is achieved, therefore, the carbon dioxide gas floatation treatment system for coal chemical industrial wastewater disclosed by the invention effectively improves the removal rate of oil materials in wastewater, and the introduction of other harmful ions is avoided.
