Description
Technical field
The utility model belongs to environmental protection and resource technical field of industrial sewage treatment, concretely relates to a kind of high saliferous
The processing system of organic wastewater.
Background technique
Greasy chemical wastewater, using gleditsia sinensis as raw material produce acidification oil discharge waste water in the grease containing high concentration, total phosphorus,
COD, ammonia nitrogen, pH value are about 2.0 or so, and for salt content up to 5~6% (being sulfate), such waste water is very difficult.Usually
There are two types of processing methods for this kind of waste water: first is that evaporation, but do not there is desired solution to remove dope after evaporation.If carrying out dangerous waste disposition
There are too high etc. reasons of processing cost, enterprise does not consider substantially；Second is that carry out biochemical treatment, due to this waste water B/C ratio be 0.4~
0.45, it is easier to biochemistry, so conventional treatment method is materialization+biochemical treatment.
But since this kind of waste water salinity is high, using in materialization+biochemical processing method, sulfate radical in waste water ion pair is biochemical
It is very unfavorable to handle.To remove the sulfate ion in waste water to greatest extent, it is all made of lime neutralisation at this stage, pH value is transferred to
10 to 11 (the appropriate excess of lime of being subject to), then carry out coagulating sedimentation.But by the salinity in above-mentioned processed waste water still 2%
Left and right, in order to not influence subsequent biochemical processing, especially anaerobism (IC reaction), using tap water to the waste water into IC reaction tower into
It goes and rushes dilute method, the dilution ratio of tap water and raw water guarantees that the concentration of sulfate radical in waste water ion exists generally in 3~4:1
For 7000mg/L hereinafter, be likely to maintain the operation of subsequent IC reaction tower substantially, such mode can handle waste water COD effect only 70%
Left and right, processing load is only 3-5kgCOD/m3D, it is very low.And since sulfate ion is still in this kind of mode processed waste water
It is excessively high, granule sludge is not formed after longtime running substantially, causes anaerobic bacteria to generate a large amount of hydrogen sulfide, inhibits the life of methane backeria
It is long, cause subsequent IC reaction tower vulnerable to impact, fluctuation of service, sludge poisoning and mortality, are commonly called as " collapsing tower " frequent occurrence
Phenomenon.Therefore IC reaction tower loses treatment effect (occurring within substantially every 3 months or so primary) substantially, seriously affect at sewage
Reason.And the processing capacity for restoring IC reaction tower again seriously affects enterprise's production generally at 1 month to 2 months or so, it is serious
If cause enterprise's stop work and production, it is very serious to business impact.

Since the hole of the diatomite of brewery is high, there are unique more hollow structures, be the good carrier of sludge growth, contain
Saccharomycete be again anaerobic bacteria growth catalyst, in IC reaction tower sludge can rapid flourish within a short period of time,
Reach the treatment effect of IC reaction tower with most fast speed, and due to weight of diatomite itself and mutual cohesion effect
Fruit, so that anaerobic sludge generates graininess, to improve the removal effect of COD.
More hollow structures of diatomite make germs collect, once the impact of the high-salt wastewater of sulphate-containing ion occurs,
Shock resistance effect can be played using the effect of the protective film outside diatomite, and due to diatomite under same volume
Porosity is big, increases apparent solid volume, to handle being greatly improved for load.With IC reaction tower runing time
Extend, the microorganism inside diatomite produces part Halophiles, to ensure that the subsequent stable operation of IC reaction tower.
