Description
Technical field
The invention belongs to Treatment of Industrial Water field, it is more particularly related to which a kind of nuclear power station acidic and alkaline waste water neutralizes
Discharge method and system.
Background technology
In the industries such as thermoelectricity, nuclear power, semiconductor, chemical industry, demineralized water production and condensation Water warfare are handed over using ion mostly
Method is changed, the trace impurity that spent ion exchange resin is gone in water removal, prepares the demineralized water or condensed water for reaching system process requirement.From
In sub- exchange process, during cationic, anionic exchange resin operational failure, excessive acid regeneration failure cationic ion-exchange resin, mistake are added
The alkali regeneration failure anion exchange resin of amount, therefore produce positive and negative resin regeneration waste water.PH value after waste water neutralizes meets
GB8978《Integrated wastewater discharge standard》, i.e. pH value control, could outer row in the range of 6-9.
Generally, in waste water and when, first by positive resin regenerate discharge acid waste water and negative resin regenerate discharge
Alkaline waste water is collected to neutralization pond, is thoroughly mixed, self-neutralization, then measures the pH value of waste water in neutralization pond, operations staff's root
Determine to add acid or alkali into neutralization pond according to pH value, be then stirred, survey pH value, by offeing medicine, stirring repeatedly, when pH value control
When system is in 6-9, start discharge of wastewater pump waste discharge.
In waste water N-process, soda acid dosage, mixing time etc. are all by operations staff according to measurement pH value and experience
It is determined that this generates problems with：
(1) according only to PH meter measured value, when adding soda acid by theoretical calculation, in by waste water and when pH value it is non-thread

The position of point etc. is different, necessarily causes stirring to reach well mixed time difference, along with pH value is in 6-9, adds
A small amount of soda acid, pH value have very macromutation, such as neutralize and only lean on one factor controlling of PH measured values with soda acid dosage, it is difficult to automatically
Neutralization reaches discharge standard, and majority of case is required for manual intervention, adds operations staff's workload.
(2) soda acid dosing is easily excessive, causes soda acid to neutralize repeatedly, increases chemical consumption.
(3) mixing time randomness is larger, when mixing time is long, loses time, electric energy；Mixing time deficiency, then give up
Water mixing is uneven, and soda acid does not neutralize fully, causes soda acid to add deficiency or excessive.
(4) discharge of wastewater is not up to standard, not only pollutes environment, can also corrode discharge of wastewater pipeline, irrigation canals and ditches produce potential safety hazard.
(5) partial deionization system includes multiple row equipment, and when regeneration frequency is high, each regenerative wastewater neutralizes, discharge is completed to need
To complete within a certain period of time, as neutralization pond waste water can not in limiting time in and qualified discharge, then occur below fail
Equipment can not be timely completed regeneration, desalting system is not run continuously, influence reliability of water supply.
