Fig. 2 is the process chart of lithium battery electrolytes cask washing waste water of the present invention.
Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.Based on this
Embodiment in invention, the every other reality that those of ordinary skill in the art are obtained under the premise of not making creative work
Apply example, broadly fall into the scope of protection of the invention.
As depicted in figs. 1 and 2, the processing method of a kind of bright lithium battery electrolytes cask washing waste water of the present invention, including
Following steps：
Step S1, Waste Water Centralized will be cleaned in regulating reservoir；In this step, it is provided with to automatically control in described regulating reservoir and be
Tank level control system in system.And automatic control system adopts EWS series of high efficiency sewage treating machine, by the PLC side of automatically controlling
Formula fully automatic operation controls.
Step S2, the waste water in regulating reservoir is carried out with secondary chemical coagulating kinetics, as follows respectively：
The first order is to feeding lime breast in fluoride waste, and reaction principle is as follows：
2F-+Ca2+-->CaF2↓,
10Ca2++6PO4 3-+2OH--->Ca10(OH)2(PO4)6↓.
The second level is that coagulant PAC aluminium salt is added in waste water, after the complexation of Al3+ and F- and aluminium salt hydrolysis
, there is the effects such as a series of exchange physical absorption, simultaneously in second level reaction tank by salt adding acid in the flocculate precipitate producing
Or nitric acid recalls to PH to normal, calcium present in water and fluorine continuing with carrying out the second secondary response sedimentation, thus realize to fluorine from
The removal of son.
Al3++3F--->AlF3↓,
Ca2++F--->CaF↓.
Step S3, the waste water after precipitation process is introduced to hydrolysis acidification pool and is hydrolyzed acidification；
Step S4, again the waste water after hydrolysis acidification is introduced to contact-oxidation pool and carries out Aerobic Process for Treatment；
In this two steps, because this sewage main component is technique waste water, less than 0.3, biodegradability is or not B/C ratio
Good, therefore should adopt hydrolysis acidification unit to improve B/C ratio, then Aerobic Process for Treatment be carried out using contact oxidation technology.This two list
Unit is and uses biological treatment, that is, utilize the metabolism of microorganism in water, the organic pollution in degradation water, reaches net
Change water quality, eliminate the purpose of pollution.Its reaction expression can be expressed as：
Organic substance+a`O2+ N+P → a (neoblast)+CO2+H2O+ can not biologicallydegraded effluent,
Cell+b`O2→CO2+H2O+N+P+ residual cell residue.
Because the COD concentration of technique waste water is higher, leading portion should adopt anaerobic technique.Current anaerobic technique mainly has
UASB, AC, anaerobic fluidized bed, regulation anaerobism etc..UASB, AC and anaerobic fluidized bed technique are higher to the clearance of COD, but technology
Have high demands, incubation time is long, typically for up to 6-12 month, do not meet the requirement of this technique.The effluent quality of this technique requires not
Height, it is therefore possible to use the method that anaerobism is adjusted, arranges anaerobism filler in regulating reservoir, anaerobism and regulating reservoir is combined into one
Body, it is possible to reduce capital expenditure and floor space, reaches the purpose killed two birds with one stone.
Novel combination type filler is set in biological contact oxidation pond, by the aeration oxygen system in automatic control system
Oxygen supply Aeration fan carry out oxygen supply.Here automatic control system adopts EWS series of high efficiency sewage treating machine, by PLC certainly
Dynamic control mode fully automatic operation controls.
Therefore be equipped with EWS high-effective microorganism sewage disposal technology, by means such as chemomorphosises, filter out multiple to sewage
Middle difference pollutant have efficient degradation power efficient microorganism species, after optimized combination, in conjunction with sewage treatment process, then throw in
To different sewage processing unit, thus improving its sewage treating efficiency.
The step S5 and then waste water after Aerobic Process for Treatment is entered to after sedimentation tank and intermediate pool MBR pond carry out MBR
Biological film process；Here, being supplied by the oxygen supply Aeration fan of the aeration oxygen system in automatic control system in sedimentation tank
Oxygen, and it is provided with the tank level control system in automatic control system in intermediate pool, with effective control liquid level.
In order to more effectively cut down pollutant, it is further added by one MBR film biological treatment, film in the end of catalytic oxidation
Biological treatment has sludge concentration height, high treating effect and the feature going out aqueous suspension bottom, increases MBR work in biological processing unit
Skill, in conjunction with EWS high-effective microorganism sewage disposal technology, makes sewage be purified.
Step S6, finally by MBR biology film process after waste water be introduced to after clear water reserviors discharge, so may insure lithium electricity
The indices of pond electrolyte cask washing wastewater effluent reach emission request.
In addition, in above-mentioned several steps, i.e. described secondary chemical coagulating kinetics, hydrolysis acidification pool, catalytic oxidation
The mud producing in pond and sedimentation tank processes the outward transport in mud cake through sludge filter press after entering sludge-tank.
The processing method of the present invention bright lithium battery electrolytes cask washing waste water, by EWS high-efficient sewage processing unit at sewage
During reason, all using automatic control technology, can according to the conditions such as water quality, water temperature change adjust automatically operational factor it is ensured that
Effluent quality, realizes Wastewater Treatment Intelligent.This process structure is compact, take up an area few, economical operation, and shock resistance concentration ability is strong,
Treatment effeciency is high, and management and maintenance is convenient, high degree of automation, and the properties of equipment all meet relevant requirement.Similar with other
Type equipment compares, and has following main feature：
1st, surrounding is no affected, mud yield is few, noise is less than the regional standard of two classes.
2nd, Automatic Control, without professional's management.
3rd, easy and simple to handle, easy to maintenance, technique is new, effect good, long service life.
4th, equipment also can need special arrangement with landform by standard arrangement.
It is specific to the actual water quality of this sewage treatment project, water yield fluctuation greatly；The features such as operational management complex operation is loaded down with trivial details,
After this technology, the inconvenience brought because of factors such as management, Operation and Maintenances can be reduced further, make sewage disposal system
System more stable operation, thus reduce operating cost.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all essences in the present invention
Within god and principle, any modification, equivalent substitution and improvement made etc., should be included within the scope of the present invention.
