Description
Technical field
The invention belongs to Application of Nuclear Technology and environmental protection technical field, be specifically related to utilize Ionizing Radiation to remove the antibiotic method of sulfamido in water.
Background technology
Microbiotic plays an important role in producing in HUMAN HEALTH and fishery, livestock industry.Yet, unemployed, metabolism is residual and production process in to the microbiotic discharged in water body environment, if without suitable processing, can affect environmental ecology after entering water body.Sulfa drugs is the class synthetic Broad spectrum antibiotics that applied range, consumption are large, and wherein sulfamethazine is one of medicine of wherein commonly using the most.Its residence time in water body environment is longer, and can cause the resistance of microorganism by food chain enrichment in organism, and HUMAN HEALTH is produced to harm.Due to its refractory organics be easy to the characteristic such as migration, its existence can be detected now in surface water, underground water and soil.Therefore, study a kind for the treatment of technology of efficient, non-secondary pollution, effectively remove the sulfamido antibiotic etc in water, seem particularly important and urgent.
Traditional water and method of wastewater treatment have Physical, chemical method and biological process etc., and these traditional treatment processs can not effectively be removed the sulfamido antibiotic etc.In recent years, high-level oxidation technology becomes focus (the Wang and Xu that people pay close attention to gradually, 2012, Advanced oxidation processes for wastewater treatment:Formation of hydroxyl radical and application, Critical Reviews in Environmental Science and Technology, 42:251-325), this technology utilizes the hydroxyl radical free radical that oxidisability is very strong (OH) to carry out the organic pollutant in oxygenolysis water.But conventional advanced oxidation processes, have relatively high expectations to the potential of hydrogen of solution as Fenton method, Fenton-like method, will add Fenton reagent, easily produces secondary pollution simultaneously.And H
2o
2add, also make processing cost greatly increase.
Summary of the invention
The object of the present invention is to provide a kind of Ionizing Radiation that utilizes to remove the antibiotic method of sulfamido in water.
Ionizing Radiation is a kind of as advanced oxidation processes, can overcome many deficiencies of conventional advanced oxidation processes.It is mainly to utilize gamma ray or rumbatron to carry out irradiation to water or waste water, and under the radiation of energetic ray, water molecules generation radiolysis, produce and have than the species of high reaction activity (as e
- aq, OH etc.), they can bring into play effect separately, with pollutent, further react, and make microorganism be degraded or remove.Under neutrallty condition, the radiation chemical reaction of water can be expressed as follows:
H
2O→e
- aq+·H+·OH+H
2+H

This reaction can not need to add any chemical reagent carrying out under potential of hydrogen arbitrarily, therefore can not produce secondary pollution yet.Simultaneously, it has the advantages such as degradation efficiency is high, speed of response is fast, contaminant degradation is thorough, for removing hazardous contaminant in organic wastewater with difficult degradation thereby (as microbiotic etc.), provides new technology, has broad application prospects.
The ultimate principle that present method is removed sulfamido antibiotic medicine in water is: water molecules by irradiation can produce there is higher reactive behavior free radical (as e
- aq, OH, H etc.), the DeR of these active groups and sulfamethazine shows on three approach: capture the hydrogen on C – H key in sulfamethazine or N – H key; With the two keys of the C=C in molecule and the two key generation redox reactions of C=N; C-N key in the saboteur.And intermediate product R, RHOH that reaction produces and ROH further reaction under the effect of oxidizing substance finally is degraded to CO
