Ammonia-nitrogen content superelevation when regeneration, normal value are：3500ppm, can instantaneously reach 5000ppm or more, and suspended matter can also reach
50ppm, Fe content can reach 100ppm, waste water water very little, according to the different regeneration about 9~20m every time of machine set type3,
The very high 45000~75000ppm of salt content.Conventional treatment be discharged to industrial wastewater neutralize other waste water blending processing will also result in it is useless
The instantaneous content of ammonia nitrogen reaches 225ppm in water, and industrial waste water centralized treatment facility can not be processed to integrated wastewater discharge standard
Emission request (≤15ppm), it is necessary to could enter industrial wastewater treatment system General Office after first carrying out ammonia nitrogen removal processing to it
Reason.
Conventional ammonia nitrogen removal processing method has blow-off method, selective ion exchange method, break point chlorination method, biological treatment etc.,
The removal rate of wherein blow-off method ammonia is low, and producing water water quality is unable to reach the emission request of integrated wastewater discharge standard, after needing increase
Continuous treatment process, and ammonia stripping is discharged into the atmosphere, and secondary pollution is caused；Selective ion exchange method removal rate is higher, fits
Intermediate concentration ammonia-containing water is closed, but generates the high-salt wastewater containing ammonia of higher concentration, processing cost pole when ion exchange resin regeneration
It is high；Break point chlorination method is very big using sodium hypochlorite amount, and running cost is high, and when actual motion is difficult the suitable dosage of control；
Biological treatment strain in the waste water of high salinity is difficult culture.In summary common process is not suitable with regeneration water quality and quantity
Feature, there are secondary pollutions, and can not be in recycle-water ammonia nitrogen.
Chinese patent CN201711206527.X discloses a kind of condensate polishing treatment regenerative wastewater ammonia recovery system, leads to
Cross degassing film only and allow gas by characteristic, the ammonia in the other side of degassing film reaches waste water with acid come cyclic absorption ammonia
Recycling；Meanwhile making to generate more free ammonias in waste water by adding alkali and heat exchanger to heat.However by heat exchanger to waste water into
Row heating, to be recycled to steam/heat water, because of waste water salt content superelevation, micro leakage can cause steam or hot water
Pollution, need add steam/heat water processing unit, it is also necessary to increase elevator pump, so as to cause cost for wastewater treatment
Increase.
