A, open the upper emulsion inlet control valve (3) of emulsion input pipe connecting (25), need purifying and emulsifying liquid after y-type filter (2), to enter emulsion input pipe connecting (25), open respectively pH adjusting agent dosing pump (5), rust-preventive agent dosing pump (11) and sterilant dosing pump (13), adjust pH adjusting agent volume pump (4), rust-preventive agent volume pump (10) and sterilant volume pump (12) are to the amount needing, pH is adjusted to medicament, rust-preventive agent medicament and bactericidal agent add emulsion input pipe connecting (25), open ozonizer (14) and regulate ozone flow by regulating ozone to adjust valve (18), by regulating air adjustment valve (16) to regulate air flow quantity, start multiphase medium pump (19) having mixed pH adjusting agent, rust-preventive agent and sterilant, and and suck in the emulsion suction pump that the need of ozone and air purify, delivering to line mixer (24) mixes, ozone and air are after multiphase medium pump (19), gaseous tension maintains within the scope of 0.3-0.5Mpa, ozone and air intake gas volume below 6% of emulsification liquid measure for needing to purify, pH adjusting agent, rust-preventive agent and sterilant have been mixed, and and suck the emulsion that the need of ozone and air purify and enter hybrid reaction inner core (41), at hybrid reaction inner core (41) through traverse baffle (26) baffling, be mixed with the microbubble and the assorted oil in emulsion, floating oil, fine particle thing, microorganism secretion liquid formation greasy filth and bubble complex body that after the emulsion decompression that ozone and air need purify, discharge, the density of complex body is less than 1, complex body floats to emulsification liquid level top becomes oil slick slag, and microorganism is killed by ozone, triphase separator (42) is collected oil slick slag, and the material that part can not float falls into shell and hybrid reaction inner core (41) bottom, by evacuated tube (38), regularly discharges,

In B, hybrid reaction inner core, liquid level rises gradually, after purifying, emulsion flows into scavenging solution collecting region (C) from hybrid reaction inner core upper port, the oil slick slag that constantly accumulation raises is collected vent pipe (28) through triphase separator (42) tapered tip oil slick mud and is discharged to the collection of oil slick mud disengaging zone (D), at oil slick mud, collect also disengaging zone (D) oil slick slag and carry out further separation, after purifying, emulsion is sunken to oil slick mud and collects also bottom, disengaging zone (D), through row's emulsion pipe (30), enter emulsion and use system, top oil slick slag floats cake tube (30) by row and discharges; After portion's perforation collector tube (33) at the end, scavenging solution collecting region (C) will purify, emulsion emulsion vent pipe (35) after purifying enters emulsion and uses system.
