The research of the effectiveness of the application of ozone for purification of sewage waters from organic pollutoin of different types
The article gives the results of theoretical and experimental research which helped to determine the criteria to evaluate the expediency of the application of ozone and also the optimum time of ozoning and ozone doze for lowering COD of sewage waters. It has been proved that some organic substances interact with ozone in diluted water solutions very slowly, but they are well oxidized with dichromate. That is why the ozoning equipment can’t be chosen in the right way if to take into consideration only the meaning of COD. The solution of this problem is to conduct tentative ozoning according to the method suggested by the authors and further data processing at the basis of the system of calculation which has been worked out. The results of the research can have practical application in the field of sewage waters purification using ozoning method.
