First stage from 0 to the 84th hour be normal work stage, at this stage sodium ion, three parameters of pH and conductance with
Time change is steady, and wherein the reading of sodium ion is fluctuated in 0.1-0.17 μ g/L, and pH is fluctuated near 6, conductivity 0.3-0.7
μs/cm。
Second stage from the 84th hour to 108 hours from for leakage amine failure stage, pH starts obviously at 84 hours stages
Rise, water outlet becomes alkalescence, and the pH rapid increase after soda acid conversion by acidity in two hours, until reaching at 108 hours
The upper limit, after tend towards stability again；And the response of conductivity is lagged compared with pH, conductivity started obvious rising at 100 hours or so,
Conductance reading tends towards stability after 108 hours.Water outlet sodium ion started obviously to rise at 100 hours, backward with runing time
Extension, water outlet Na ion concentration incrementally increase, until rising to 0.62 μ g/L by 0.1 initial μ g/L at 108 hours.

For degree in the case where, the cation exchange resin out-of-service time that ETA is added is greater than NH3And MPH+NH3It mixes under basifier operating condition
Cation exchange resin out-of-service time, the cation exchange resin out-of-service time under ETA operating condition is about NH3Operating condition
2.93 times, it is seen then that the Wastewater Sample handled with ETA is to the destruction ratio NH of cation exchange resin3The Wastewater Sample of processing
It is small to the destruction of cation exchange resin.
It can be seen that in conjunction with Fig. 8 to Figure 10 and table 2, for APG cation exchange resin, three kinds of operating condition runing times are close,
It is followed successively by ETA, NH from long to short3、MPH+NH3Mix basifier operating condition, the concentration by basifier known to theory is higher, to sun from
The destruction of sub-exchange resin is bigger, and the out-of-service time is also faster, by Tables 1 and 2 it is recognized that while the concentration of ETA, MPH are
NH33-4 times of concentration, but under three kinds of operating conditions, the efficiency lost resin time is close, it may also be said to bright ETA, MPH+NH3Mix basifier
To the destruction ratio NH of cation exchange resin3The Wastewater Sample of processing is small to the destruction of cation exchange resin.
