Continuous purification separation separates online each pollutant using in emulsion, selected by each separative element exist
During purifying various pollutants, new pollutant is not introduced, it is ensured that the original composition of emulsion does not change,
Realize circularly purifying and the continuous use of emulsion；
The ozone generated using ozone generator is sucked before the second transfer tube, is controlled by pressure, improves ozone in breast
Change the concentration in liquid, a large amount of micro-bubbles are generated by depressurizing release, promote bactericidal effect, and can be with oil slick, miscellaneous oil and tiny
Suspended matter collides to form wadding grain and bubble complex and be removed, and can to emulsion progress iterative cycles purification, in addition,
For ozone generator, effect is very good, and does not introduce any chemical substance, therefore it will not be to emulsion for the sterilizer used
Secondary pollution is generated with ambient enviroment, working environment can also be improved；
It, can be very tiny particles content and colloid pollution object in emulsion, by electrocoagulation using electrocoagulation separation means
Effect forms larger particles, then forms bubble wadding grain complex by ozone air-float and be removed, simultaneously, moreover it is possible to put on emulsification
