In embodiment, high ammonia-nitrogen wastewater with 15 cubic meters/hour (flow according to design regulating tank size variable, regulating tank capacity/flow ＞ 0.4 hour in coagulation device, such as, the water yield that in coagulation device, regulating tank can store is 6 cubes, flow is less than 15 cubic meters/hour) enter 1# regulating tank 12 from water inlet 1, open agitating device 2, open device for absorbing tail gas, process through offgas duct 22 absorption, sodium hypochlorite electromagnetic valve switch is controlled according to ORP instrument probe 5 detection display, ORP instrument is set lower than 600mV and controls to open sodium hypochlorite electromagnetic valve 3 and add sodium hypochlorite, control to close sodium hypochlorite electromagnetic valve 3 higher than 620mV, stop adding sodium hypochlorite；Simultaneously detected pH, pH instrument during reaction by pH instrument probe 6 to be set lower than 6.80 and open liquid caustic soda electromagnetic valve 4, add liquid caustic soda regulation pH, close liquid caustic soda electromagnetic valves 4 higher than 6.90；Waste water is entered 2# regulating tank 13 by 1# regulating tank 12 through apopore 7, and the stirring of agitated device 2 is mixed even；3# regulating tank 14 is flowed into again by spout hole 8, detected display by the ORP instrument probe 16 in 3# regulating tank and control sodium hypochlorite electromagnetic valve switch, this ORP instrument is set lower than 550mV and controls to open sodium hypochlorite electromagnetic valve 18 and add sodium hypochlorite, control to close sodium hypochlorite electromagnetic valve 18 higher than 580mV, stop adding sodium hypochlorite；Simultaneously detected pH, pH instrument during reaction by pH instrument probe 17 to be set lower than 6.80 and open liquid caustic soda electromagnetic valve 19, close liquid caustic soda electromagnetic valves 19 higher than 6.90；Waste water enters into 4# regulating tank 15 through apopore 9, water outlet pH is detected by pH instrument probe 11, pH instrument is set lower than 6.80 and opens liquid caustic soda electromagnetic valve 20, liquid caustic soda electromagnetic valve 20 is closed higher than 6.90, added appropriate sodium sulfite solution by sodium sulfite solution pipeline 21 entrance simultaneously, finally, by outlet 19 water outlet up to standard.(another: when regulating tank is empty, first each regulating tank to be full of clear water.)
One high-efficiency and continuous of the present invention processes high ammonia-nitrogen wastewater device and processing method operation principle is as follows:
(1) if not controlling pH, directly adding sodium hypochlorite and removing ammonia nitrogen, then there will be removal not exclusively；It is known that sodium hypochlorite is alkalescence, wastewater pH can be made to increase if directly adding sodium hypochlorite, during it practice, pH rises to about 11, reaching break, now can react rapidly, consume sodium hypochlorite, produce nitrogen, pH declines rapidly, and pH is the most violent closer to 7 reactions.PH reduce the ammonia nitrogen removed in degree visual response how many depending on, ammonia-nitrogen content is high, removal the most, pH fall the lowest；By net reaction it is: NH4 ++1.5HOCl→0.5N2↑+2.5H2O+2.5H++1.5Cl-It is also seen that；
(2) change and the pH value of electrode potential also has certain relation, and pH is the highest, and electrode potential is the lowest, and pH more low electrode current potential is the highest；Therefore, waste water is before adding sodium hypochlorite and removing ammonia nitrogen, and pH is unsuitable too high, and otherwise, sodium hypochlorite adds how many electrode potentials does not all reach 600mV, and pH value also can rise, so because this genus of sodium hypochlorite alkalescence, it will causes an endless loop, wastes medicament；
(3) experiment display pH treatment effect between 6～8 is preferable；Best results during pH=7, when pH is relatively low, contents of residual chlorine increases sharply, NH4 +-N clearance reduces, and this is mainly the by-product NCl that chlorination reaction generates3Increase and cause, byproduct of reaction NO when pH is higher3 -Increase, remaining NH4 +-N concentration raises, due to NO3 -Non-oxidative, contents of residual chlorine rises relatively slow.By effective chlorine residue and Na2SO3Mol ratio is that 2:1 adds Na2SO3, chlorine residue can be completely removed.Finding in process of the test, reacting pH requirement harshness, when pH deviation 7 is bigger, reaction is relatively slow, and is equal to when 7 be swift in response generation and cause pH rapid decrease, need to persistently supplement liquid caustic soda to maintain pH near 7；
(4) sodium hypochlorite is with the course of reaction of ammonia, and its electrode potential has respective change；Generally, copper-containing wastewater Wastewater by Electric electrode potential after addition sodium sulfide sinks copper is about-200mV, and add sodium hypochlorite in this waste water reaching electrode potential during break is 550mV-600mV；When vigorous reaction, electrode potential can rise rapidly and can reach more than 1000mV, when pH stable about 7 time, electrode potential can fall after rise to about 550mV；Therefore, in tandem reaction sequence, ORP meter can be used to control the addition of sodium hypochlorite, stop when ORP value reaches 620mV adding sodium hypochlorite, add sodium hypochlorite when ORP falls back to below 600mV；
(5) during two stage treatment, because ammonia-nitrogen content is fewer than one-level, electrode potential is arranged can be more on the low side than one-level.
Above-described embodiment is only for technology design and the feature of the explanation present invention; its object is to allow person skilled in the art will appreciate that present disclosure and to be carried out; can not limit the scope of the invention with this; all equivalence changes made according to spirit of the invention or modification, all should contain within the scope of the present invention.
