A () is filtered fluid and is filtered fluid inlet (4-3) enters from storing the left case basifacial of fluid chamber (4), at A type dividing plate (1) water flowing breach a2 (1-2), outstanding tabula a3 (1-3) and Type B dividing plate (2) water flowing breach b2 (2-2), under outstanding tabula b3 (2-3) guides, complications form electric field by capacity plate antenna, are finally filtered fluid outlet (4-4) outflow from storing top, fluid chamber right case face; Be filtered fluid when complications form electric field by capacity plate antenna, be filtered fluid intermediate ion and be attracted to the upper filtration, purification realizing being filtered fluid of electrolysis insoluble electrode (3); Capacity plate antenna applies volts DS 2-6V; Be filtered fluid by capacity plate antenna flow velocity 0.5-0.6m/min:
(b) adopt known technology to confirm in technique on electrolysis insoluble electrode absorption be filtered ion in fluid oneself saturated time, cut off the electricity supply, change valve, stop being filtered fluid and flow into; Change and input backwash fluid from storing fluid chamber (4) right case basifacial backwash fluid import (4-1); backwash fluid is at A type dividing plate (1) water flowing breach a2 (1-2); outstanding tabula a3 (1-3) and Type B dividing plate (2) water flowing breach b2 (2-2); under outstanding tabula b3 (2-3) guides; tortuous by capacity plate antenna Special composition, flow out from storing top, fluid chamber left case face backwash fluid outlet (4-2); Owing to cutting off the electricity supply; capacitive field rut disappears, and ion, from desorption electrolysis insoluble electrode (3), is carried by backwash fluid; flowing out from storing top, fluid chamber left case face backwash fluid outlet (4-2), realizing electrolysis insoluble electrode regeneration purification;
Backwash fluid is be filtered fluid by the 1-20 of capacity plate antenna flow velocity doubly by capacity plate antenna flow velocity;
C () gets back to program (a).
