Description
Technical field
The utility model belongs to technical field of water treatment equipment, is related to a kind of high ammonia nitrogen desulfurization wastewater integrated treatment dress
Put.
Background technology
The principal character of desulfurization wastewater includes：1st, salt content is high, and excursion is big, typically in 30000mg/l-60000mg/
l；2nd, concentration of suspension is high, mostly in more than 10000mg/l, reaches as high as 60000mg/l；3rd, hardness is high, easy fouling, Ca2+、
SO4 2-、Mg2+Content is high；4th, corrosivity is strong, and C 1 content is high；5th, ammonia-nitrogen content is high, mostly in more than 1500mg/l；6th, water quality with
Time and operating mode and change；7th, contain each Heavy Metallic Elements composition in water quality.
The typical method of wastewater treatment of domestic current is all based on the discharge characteristics of desulfurization and dedusting waste water and is derived, for
Different types of pollutant, its respective cutting mechanisms are as follows：1) acid-base value adjusts (removal) and first adds milk of lime in waste water
Or other alkali electroless reagents are (such as：NaOH etc.), pH value is adjusted to 6～7, is that subsequent treatment process link creates good technology
Condition, while can effectively remove fluoride (products C aF in the link2Precipitation) and part heavy metal.Be subsequently adding milk of lime,
Organic sulfur and flocculant, pH is risen to 8～9, so that heavy metal is precipitated in the form of hydroxide and sulfide.2) weight such as mercury, copper
The removal precipitate and separate of metal is a kind of conventional metal separation, in addition to active metal, perhaps polymetallic hydroxide molten
Xie Du is less.Therefore desulfurization wastewater is typically using soluble hydroxide, such as NaOH (NaOH) is added, produces hydroxide and sink
Form sediment and carry out separation of heavy metal ions.It is noted that as, under different pH value, the solubility product of metal hydroxides is differed relatively
Greatly, therefore its pH value should strictly be controlled when reacting.In desulfurization wastewater is processed, between general control pH value 8.5～9.0, at this
In the range of can make some heavy metals, such as iron, copper, lead, nickel and chromium generate hydroxide precipitation.For heavy metals such as mercury, copper, typically
Using addition dissolvable sulfide such as vulcanized sodium (Na2S), to produce Hg2S, CuS etc. are precipitated, and both deposits solubility is all
Very little, the solubility product order of magnitude is 10-40～10-50Between.Vulcanized sodium is used for mercury, as long as adding less than 1mg/L, so that it may to little
Mercury generation effect in 10 μ g/L concentration.In order to improve heavy metal precipitation process, a kind of mud that well can be precipitated is prepared, typically
Trivalent iron salt such as FeCl can be used3And the flocculant of generally anion state.By above two stages for the treatment of, you can reach heavy metal
Mark discharge.There are some techniques, with Ca (OH)2Replace NaOH, while producing CaF in course of reaction2、CaSO3、CaSO4Precipitation
Thing, to separate the salts substances such as fluoride, sulphite, sulfate.
In existing desulfuration waste water treatment process, as described above, main based on chemical treatment, using coagulant precipitation work
Skill, mainly for the Ca in waste water quality2+, suspension, heavy metal processed, and have ignored the presence of high ammonia nitrogen in waste water,
Removing mode is not effectively processed to the high ammonia nitrogen in desulfurization wastewater.Desulfurization wastewater after process is directly given up with plant area other stocks

The very big impact of life, during biochemical treatment, as the high ammonia nitrogen of system is present, the first scale that sets of system is greatly increased, with
Need to be continuously replenished substantial amounts of carbon source during Shi Yunhang, cause the rising of Integral biochemical system operation cost.
Removal of the ammonia nitrogen in waste water is a difficult problem.In traditional method, biological denitrificaion method, break point chlorination method are suitable only for
Process Low Concentration Ammonia Containing Wastewater；Ion-exchange needs to regenerate resin, and the high ammonia-nitrogen wastewater that regenerated liquid is produced needs to do
Process further；Chemical precipitation method processing cost is high, and efficiency is low；Catalytic wet air oxidation requires severe reaction conditions, is not easy to
Control；Electroosmose process needs electrical energy drive, high energy consumption；Ammonia still process (stripping) or stripping technical finesse efficiency low, easily cause two
Secondary pollution.It is clear that the method for several ammonia nitrogen in waste water removings described above respectively has pluses and minuses, but these methods all have one
Fixed shortcoming and application limitation, such as processing cost are high, and condition control is strict, easily causes secondary pollution etc..

Processing unit, after what Type B film process later, the ammonia nitrogen in waste water reaches setting discharge standard, is emitted at comprehensive wastewater
Reason system carries out biochemical post processing.
Described ammonia nitrogen pre-processes A type membrane extraction device, NH_3-N treating Type B membrane extraction device, using doughnut film liquid
Phase extraction technology, the principle of AEM film deamination are as follows：
Ammonia nitrogen is balanced below existing in water：NH4 ++OH-←→NH3↑+H2O, when in waste water, PH is improved or temperature rises
When, above-mentioned balance will move right, ammonium ion NH4 +Become free gaseous state NH3.At this moment gaseous state NH3Device can be passed through
The acid that the micropore of intimal surface mutually enters film opposite side from the waste water of film side absorbs liquid phase, absorbed at once by acid solution again become from
The NH of sub- state4 +.Keep NH of the PH of waste water more than 10, in such waste water phase4 +NH will continuously be become3To absorbing liquid
Mutually migrate.Constantly decline so as to the ammonia nitrogen concentration of waste water side, until it reaches the discharge standard of setting；And acid absorbs liquid phase due to only
There are acid and NH4 +, so formed is very pure ammonium salt, and reaches certain concentration after constantly circulating, can be by
Recycle.The essence of the process is diffusion and the continuous process for absorbing, and parses and absorbs in the both sides of film while completing.By-product
