Abstract
The invention discloses a kind of processing system for removing nitrate nitrogen in industrial wastewater, including sump, coarse rack, inclined-plate clarifying basin, aeration nitrification tank, the organic rhodium catalysis polymerization reaction trough of electrion, water purifying tank, weak nitrocotton drying formation system etc..The system creativeness make use of high-energy discharge graded effect caused by high-voltage arc, nitrate ion in waste water under the conditions of this, catalytic polymerization occurs on the organic compound surface of transition metals rhodium, it is broken the ionic bond of nitrate ion in waste water and recombinates, nitrocellulose can be generated, can be collected and realizes the recycling of resource（Manufacture cinefilm, celluloid and zapon etc.）；Simultaneously as this reaction carries out in liquid matrix, therefore reaction efficiency and speed are controlled, and can be only generated weak nitrocotton, have prevented the generation of the higher strong nitrocotton of nitrogen content or collodion, so as to eliminate the risk exploded in operation.
Description
Technical field
The present invention relates to a kind of processing systems for removing nitrate nitrogen in industrial wastewater, belong at the waste water in environmental protection
Reason field.
Background technology
Nitrate nitrogen is one of major pollutants polluted to surface water and groundwater, while is also that surface water body is rich
" arch-criminal " of nutrient laden.Annual amount of nitrogen fixation is considerably beyond the nitrogen amount discharged by denitrification in the world,
So as to cause accumulation of the nitrate nitrogen in water environment, the nitrogen content for making various water bodys in nature is significantly exceeded.
At present, worldwide pollution of nitrate nitrogen is increasingly severe.For example, the PRIN research reports of Italy
Show：Although country makes great efforts to reduce the discharge of nitrate nitrogen in terms of intensive agricultural, nitrate nitrogen is still Tuscany
One of the important pollutant in area, nitrate nitrogen content is above 50mg/L in about 35% surface water body；AlabamaState,U.S.A
The river basins survey report of nearly 2 years is all pointed out：It is above in the middle part of the state with the nitrate nitrogen content in northeast major part basin
63mg/L, other area some have been even more than 112mg/L；The nitrate nitrogen content of the agricultural irrigation water of Germany 50% is
More than 60mg/L；The nitrate nitrogen content of Paris, FRA in the neighbourhood has reached 180mg/L.
The European and American areas exceeded phenomenon of water body nitrate nitrogen is so serious, and the pollution of nitrate nitrogen present situation of China's water environment is similary
It allows of no optimist.In the recent period, the monitoring materials of 77 underground water wells in Changchun are shown：The recall rate of " three nitrogen " has all reached 100%, nitre
The exceeding standard rate of hydrochlorate nitrogen all maintains higher level；Efficiency in Buildings in Tianjin Area has carried out pollution of nitrate nitrogen to 201 earth's surface water spot positions and has showed
Shape is investigated, the results showed that：The surface water body azotate pollution situation of most of industrial area and agricultural reclamation area is extremely serious.
Nitrate in water is the most stable of nitrogen compound in the nitrogenous compound of various forms under aerobic environment, also
It is decomposition product of the itrogenous organic substance through mineralization terminal stage.Nitrate toxicity itself is very low, but it enters human body
After can be reduced to nitrite, toxicity increases, and is 11 times of nitrate toxicity.At the same time, the nitrate in water environment and
Nitrite is in various itrogenous organic substances（Amine, amide, urea, guanidine, cyanamide）Under the action of, it can also form chemical stability, cause
The various N- nitrosos compounds of group of the cancer N-nitrosamine different with mutagenesis mechanism and nitrosoamide.
Existing nitrate nitrogen removal methods include：
（1）Physical removal method：Mainly include membrane separation process（It is electrodialysis, reverse osmosis）With ion-exchange etc..
（2）Chemical reduction method：It is main to include ripple metal deoxidization and catalytic reduction method etc. living.
（3）Biological decomposition method：Under anaerobic condition nitrate nitrogen as denitrifier respiratory chain terminal electron acceptor and by
It is reduced to N2O or N2Process.
Above-mentioned tradition administering method has some disadvantages, and such as investment and operating cost are high, supplies consumption is big, nitrate
Nitrogen removal efficiency is low etc..Therefore, it is necessary to break away from existing Treatment process route, new Approach of Removal of Nitrogen is createed, and then is developed
A kind of nitrate nitrogen treatment technology of new type.
The content of the invention
To solve the deficiencies in the prior art, the present invention provides a kind of processing for removing nitrate nitrogen in industrial wastewater
System, the system include sump, coarse rack, inclined-plate clarifying basin, aeration nitrification tank, the organic rhodium catalysis polymerisation of electrion
Slot, water purifying tank, weak nitrocotton drying formation system；Wherein the industrial wastewater containing nitrate nitrogen is entered by waste line and catchmented
Well, carries out centralized collection herein and preliminarily stabilised is adjusted, and the outlet of sump connects coarse rack by waste line, removes herein
Major diameter solid matter in industrial wastewater, the outlet of coarse rack connect inclined-plate clarifying basin by waste line, herein further
The insoluble matter in waste water is removed, the outlet of inclined-plate clarifying basin connects aeration nitrification tank by waste line, will be in waste water at this
Nitrogen substance be completely converted into nitrate nitrogen class, be aerated nitrification tank outlet pass through waste line connect the organic rhodium of electrion
Catalytic polymerization slot, the outlet of the organic rhodium catalysis polymerization reaction trough of electrion connect water purifying tank, water purification by waste line
The outlet in pond by waste line will pass through the system treated purification water outlet outside arrange, meanwhile, the organic rhodium catalysis of electrion
The nitrocellulose generated in polymerization reaction trough is discharged by granular material discharged mouth, and dries formation system into weak nitrocotton,
It can be recycled after weak nitrocotton drying dehydration and compression moulding；Wherein, the organic rhodium catalysis polymerization reaction trough of electrion
Outer layer covers have a groove body insulating protective layer, inside is silicon carbide ceramics structure, and the upper right quarter of reactive tank is equipped with inlet valve, left
Lower part is equipped with flowing water Valve, and groove body middle body is equipped with four carbonyl of dichloro, two rhodium porous aggregate, and packing layer lower part is connected with
Grain object floss hole, arranged on left and right sides siding center is respectively equipped with a high-voltage discharging electrode, each in reaction tank bottom arranged on left and right sides
Equipped with a stirrer paddle, industrial wastewater enters reactive tank by the inlet valve of the organic rhodium catalysis polymerization reaction trough of electrion
