(54) REPAIRING PROCESS METHOD OF SEWAGE WATER OZONATION (57) The invention relates to wastewater treatment by ozonation. The purpose of the invention is to increase the degree of purification and decrease the flow rate by increasing the accuracy of the adjustment. The method includes changing the current supply of the ozonizer and the flow rate of air supplied to it, depending on the water flow and the concentration of ozone in the exhaust gas. The novelty in the process is that the pressure of the ozone-air mixture in the reactor is changed by varying the wastewater flow rate depending on the residual concentration of oxidizable compounds at the outlet of the reactor. 1 PC.

The invention relates to the purification of wastewater by ozonization and can be used in sewage treatment plants and installations that use ozone in an oxidizing agent.

The purpose of the invention is to increase the degree of purification and reduce the consumption of ozone by increasing the control accuracy. The drawing shows a scheme for implementing a method for regulating the process of ozonization of wastewater.

The method is carried out as follows.

Sewage water through line 1 through flow meter 2 is fed to ejector 3, where it is replaced with an ozone-air mixture and the resulting ozone-water emulsion through pump 4 is sent to a water ozonation reactor 5, made in the form of a column equipped with a spray gun 6 and with a submerged nozzle 7. The liquid level in the reactor is maintained below the nozzle by a vacuum pipe 8. Purified purified water is discharged through line 9.

Air through the pipeline 1 o is fed to the ozone generator 11, from the outlet of which the ozone-air mixture is fed to the mixing with waste water to the ejector 3. The exhaust gas is discharged by means of a plunger 8 through the residual ozone thermo-catalytic decomposition apparatus 12 and the exhaust pipe 13. (

The regulation of the ozonation process is carried out as follows. The residual concentration of oxidizable compounds in the treated water. at the outlet of the reactor 5, the content analyzer oxidizes 1x compounds 14, the signal from which is fed to the regulator 15 of the ratio of the concentration of ingredients, recorded by

The lattice 17 of the initial ozone concentration, the residual ozone concentration sensor 18 and the flow meter 2 feed the input unit to the operation unit 19, which calculates the required supply current and the flow rate of air supplied to the ozone generator 11. With the help of 1o of the Transformer 20 and the air metering unit 21, the voltage and the flow rate of the feed gas are simultaneously scaled.
