Experimental Research On The Treatment Of Reusable Water By Ozonation Process

The text made research with microfiltration membrane effluent of secondary effluent, make use of ozone technique progress depth transaction. In the experiment, the physical absorption mass transfer coefficient can be used to ozone mass transfer efficiency directly. In the research of ozone oxidation mechanism, point out that ozone molecule play the main oxidation state.In the mechanism search that oxidizes in the ozone, the oxadation of molecule ozone has a main action. In the study of different influent water quality, while the influent chroma is 50, the ozone dosage is 4.1 mg/l, the contacting time is 20 min, the effluent can reach the standard, and the ozone dosage measures for the 5.7 mg/l, contacting time for 10min, the effluent also can reach the standard. When the influent chroma is 85, the best ozone dosage is 11.8mg/l, and the best contacting time is 15min. When the influent chroma is 120, the best ozone dosage is 17.7mg/l, and the best contacting time is 20min.The molecular weight of the ozone influent water organism is almost smaller than 4k. And after ozone oxadation, the ratio that small molecule organic matter also has an obvious exaltation. Joining the catalyst can strengthen the action of ozone oxadation organic matter, when TiO₂ mix with MnO₂, MnO₂ and TiO₂ everywhere and alone use by 1∶3 mixes to raise above 5%.Overall, the ozone depth transaction is effective techniques for water reuse; Use pilot experiment to imitate technical actual run - time, the experimental results have important academic significance and application value.
