1) when system starts, feed tube 19 starts into waste water, and the 1st~4 resin column is closed, the 5th~20 resin column group
Into absorption group.
2) absorption group (i.e. the 5th~20 resin column) enters adsorbed state, full when being reached into the wastewater volume of resin column
(60%~80% is can be controlled in during with adsorb cumulative volume 80%), allow the 20th resin column to terminate to adsorb and enter alkali cleaning shape
State, the 4th resin column substitute enters adsorbed state, formed new absorption group (new absorption group include the 4th resin column and the 5th~
19 resin columns, the 20th resin column is excluded from absorption group, is not counted in new absorption group, is prepared to enter into reproduced state), into alkali
The resin column for washing state enters backwash state after the completion of alkali cleaning, while the 19th resin column enters alkali cleaning state, now, inhales
Attached group of feed liquor cumulative volume reaches the 5% of absorption group saturation absorption cumulative volume, and the 3rd resin column substitute enters adsorbed state, according to
It is secondary to analogize so that absorption, alkali cleaning, backwash, pickling, five kinds of states of backwash are carried out simultaneously in different resin columns, in system
16 resin columns are kept to be in adsorbed state, remaining resin post is in non-adsorbed state (i.e. reproduced state) so that waste water is lasting
Processed into system, be not in that waste water is detained, the waste water COD stabilization discharged after adsorption treatment is led in below 50mg/L
Often in 30~50mg/L (not including 50mg/L), meet《Urban wastewater treatment firm pollutant emission standard》(GB18918-2002)
