Description
Technical field
The present invention relates to a kind of method for handling antibiotic waste water, belong to industrial waste water treatment.
Background technology
Antibiotic is by microorganism（Including bacterium, fungi, actinomyces）Or the animals and plants such as other height are in life process
Produced has antipathogen or a class secondary metabolite of other active materials, is that one kind can disturb other living cells to send out
The chemical substance of function is educated, it is broadly divided into aminoglycoside, Tetracyclines, quinolones, macrolide etc..It can be used for
Suppress infectious diseases, so as to ensure health.But a large amount of of antibiotic use, and make mankind's drug resistance and antibiotic in environment
In residual quantity be continuously increased.Antibiotic has high bioactivity, persistence and bioconcentration simultaneously, sends out zoonosis
Sick rate increase, causes slow poisoning.Research shows that tetracycline can suppress the synthesis of microalgae protein and the generation of chloroplaset,
Suppress the growth of microalgae, can also suppress the activity of enzyme in chloroplaset, so as to suppress the growth of plant, the root system of plant is produced compared with
Big toxicity.
Antibioticses waste water belongs to used water difficult to degradate, because its Ke Shengization≤0.3, i.e. B/C are than high, and biodegradability is strong, most saves
Can effective processing method be exactly to use biologic treating technique, i.e. the bioremediation of anaerobism+aerobic, but due to biological treatment
Limitation, that is, there is the contamination index such as quite a few COD that can not be degraded by microorganisms, can not still reach that regulation will
Ask, it is necessary to which further deep treatment is carried out to pollutant, i.e., using chemical method, the pollutants such as non-degradable COD are carried out
Mandatory exhaustive oxidation is decomposed, it is ensured that sewage can be according to environmental requirement qualified discharge.Conventional addition aluminium salt or（With）The list of molysite
Level or multistage flocculation treatment operation operation are simple, but clearance is low, it is high to invest larger, operating cost.And the sludge quantity produced
Greatly, sludge is in small, broken bits, is difficult dehydration, while to soluble organic matter removal ability.Due to containing aluminium salt in sludge, easily production
Raw secondary pollution.In addition, the device such as membrane filtration, electrodialysis, counter-infiltration and other oxidations is also because easily blocking, being difficult to safeguard pipe
Reason, without being often used.
Therefore, in order to improve the treatment effect of antibiotic sewage, developing a kind of energy-efficient new processing method turns into
Current study hotspot, has positive meaning to antibiotic technical field of sewage.
