Description
Technical field
The present invention relates to a kind of new antibiotic waste water electron beam handling process, belong to Application of Nuclear Technology and medical sewage
Process interleaving techniques field.
Background technology
China is one of production of antibiotics state the biggest in the world at present, but the small scale of most of pharmacy corporation, produce work
Skill falls behind, and the water yield of pharmacy waste water and change of water quality are all very big, and intractability is higher.Conventional sewage handling process is to pharmacy waste water
In pharmaceutical intermediate, the Recalcitrant chemicals such as drug residue removal increasingly difficult, incompletely processed waste water enters rivers
Afterwards by serious oxygen consumption, destroy the self-purification capacity of natural water body, cause water quality blackening, body eutrophication, propagate pathogenic bacteria, lead to public affairs
Evil.Under the limited value of discharge standard of currently national increasingly stringent controls, production of antibiotics enterprise faces larger environmental protection pressure mostly
Power, realizes waste water low cost and effective process is extremely urgent.
The treatment technology of current antibiotic waste water mainly has physico-chemical process, bioanalysises and advanced oxidation processes.Physico-chemical process mainly wraps
Include the modes such as coagulation, precipitation, absorption, air supporting, burning, filtration, reverse osmosiss, but need to add a large amount of chemical agents so that processing
Cost improves, complex operation and easily cause secondary pollution, therefore all limits their application to a certain extent.Due to antibiotic
Waste water main component is difficult degradation poisonous organic wastewater, has certain inhibitory action to biology, needs big during the water inlet of oxygen consumption technique
Amount clear water dilution, power consumption is very big, high cost, and handling rate is low.High-level oxidation technology is produced by certain oxidation reaction to be had
The hydroxyl radical free radical (oh) of extremely strong activity, organic pollution in non-selectivity ground oxidized waste water, will be organic for macromole in waste water
Mass degradation is small organic molecule or direct mineralising is co2And h2O, has that response speed is fast, it is complete, nuisanceless, suitable to process

The catalytic efficiency of agent is not high, and the response time is long, is unfavorable for industrial applications；Electrocatalytic oxidation export license is big, still in experiment
Room conceptual phase；Fenton processes the more of application, but needs to add excessive ferrous iron, leads to later stage sludge output big, operating cost
High；Ozone oxidation has selectivity, and in water, dissolubility is low, and utilization rate is low, easily decomposes and need to now produce existing use, and high cost operates skill
Art has high demands；
(3) present treatment technology, still using the clearance of Organic substance as the foundation differentiating, lacks antibiotic waste water and processes water outlet
The detection of bio-toxicity and biological value and standard, the safe and sanitary of serious threatening environment.
