The running of resin column is as follows：
1) when system starts, feed tube 19 starts into waste water, and all imported valves of the first resin column 1 are turned off；Second
The water inlet valve of the resin column 10 of resin column 2~the tenth is opened, and water outlet tube valve is opened, and remaining valve is turned off.
2) system operation to the waste water cumulative volume for entering the resin column 10 of the second resin column the 2~the tenth reaches this 9 resin columns
When saturation adsorbs 80% (caning be controlled in 80%~95%) of cumulative volume, water inlet valve and the water outlet of the first resin column 1 are opened
Tube valve, the water inlet valve and water outlet tube valve of the second resin column 2 are closed, while open the alkali inlet tube valve of the second resin column 2
Door and alkali outlet pipe valve, alkali inlet tube and alkali outlet pipe valve are closed after alkali cleaning, open flushing water valve, closed after flushing
Flushing water valve, open acid inlet tube valve and go out acid tube valve, after pickling, close acid inlet tube and go out acid tube valve, open
Flushing water valve, the zeolite regeneration process of the second resin column 2 is completed after flushing, i.e. the first resin column 1 enters adsorbed state
When, the second resin column 2 enters non-adsorbed state.
3) after the zeolite regeneration process for completing the second resin column 2, the second resin column 2 enters adsorption process, the second adsorption column
New absorption group is formed after into adsorbed state with remaining adsorption column, still (new absorption group includes first to new absorption group for 9 resin columns
Resin column 1, the second resin column 2 and the resin column 10 of the 4th resin column the 4~the tenth, the 3rd resin column 3 exclude from absorption group, no
New absorption group is included in, is prepared to enter into reproduced state), the feed liquor cumulative volume incrementss of the absorption group reach the absorption of absorption group saturation always
Volume 20% when, open the zeolite regeneration process of the 3rd resin column 3, the elution of remaining resin post and regeneration circulate successively into
OK so that system remains that 9 resin columns are in adsorbed state, and a remaining resin column is in non-adsorbed state.
The processing water of the system is 20m3/ h, accordingly, industrial soft water enter from wash water import 15, and its flow is 1m3/
H, processing water flow are 20m3/ h, elution flow quantity are 0.5m3/ h, backwash deslagging water-carrying capacity is 0.6m3/h。
The system and method realize that waste water enters from pending liquid import 14, and industrial soft water enters from wash water import 15,
Backwash cycle is set in the controller of automatic control unit 13, and system calculates the resin ratio of operation and backwash, obtained most automatically
Excellent control mode.Water outlet after processing from the discharge for the treatment of fluid outlet 16 of system side, and eluent after mixing from another
The washing water outlet 17 of side is discharged, and eluent can be further processed.
The resin column of said system has resin to be in vacant, all resins all exist during normal operation when starting first
Operation, without the vacant time.
On water quality：The system only removes COD, and water outlet COD can be controlled by the control of adsorption time, water outlet COD controls
System is in 30~50mg/L (not including 50mg/L), satisfaction《Urban wastewater treatment firm pollutant emission standard》(GB18918-2002)
In requirement of the one-level A standards to COD, less than 50mg/L.
Embodiment 2
The present embodiment illustrates by taking 20 resin columns as an example, and remaining structure of system is identical with embodiment, to resin column according to
Secondary numbering 1-20, running situation are as follows：
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, when the wastewater volume for entering resin column reaches full
(60%~80% is can be controlled in during with adsorb cumulative volume 80%), is allowed the 20th resin column to terminate to adsorb and is entered alkali cleaning shape
State, the 4th resin column substitute enter adsorbed state, formed new absorption group (new absorption group including the 4th resin column and the 5th~
19 resin columns, the 20th resin column exclude from absorption group, are not counted in new absorption group, are prepared to enter into reproduced state), into alkali
The resin column for washing state enters backwashing 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 five kinds of absorption, alkali cleaning, backwash, pickling, backwash states 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
Handled into system, be not in that waste water is detained, the waste water COD discharged after adsorption treatment is stablized in below 50mg/L, leads to
Often in 30~50mg/L (not including 50mg/L), meet《Urban wastewater treatment firm pollutant emission standard》(GB18918-2002)
In requirement of the one-level A standards on COD.
The processing water of the present embodiment system is 100m3/ h, accordingly, industrial soft water enter from wash water import 15, and it flows
Measure as 5m3/ h, processing water flow are 100m3/ h, elution flow quantity are 2.5m3/ h, backwash deslagging water-carrying capacity is 2.5m3/h。
In summary, adsorption system of the present utility model mainly has the following effects：1st, the suction that resin column continuously circulates is realized
Attached regenerative process；2nd, by the parallel efficiency run, improve system operation of three links separation of resin regeneration so that part resin
Post is in non-adsorbed state, including alkali lye elution, acid solution elution, backwash process, and remaining resin post is in adsorbed state, alternately
Circulation, ensure that water outlet COD is stable；3rd, each monomer resin post relatively operates independently from so that system is more stable, is not influenceing
In the case that other resin columns are run, online replacing renewal remaining resin post is realized.
Above-described embodiment only illustrative principle of the present utility model and its effect are new not for this practicality is limited
Type.Any person skilled in the art can all be carried out without prejudice under spirit and scope of the present utility model to above-described embodiment
Modifications and changes.Therefore, such as those of ordinary skill in the art without departing from the essence disclosed in the utility model
