Abstract
The invention relates to a method for removing antibiotics in water by using UV/H2O2 combination. The method comprises: adding persulfate into pretreated waste water at first to obtain a mixed solution, then adjusting the pH value of the mixed solution by using acid liquor or alkali liquor, then carrying out first irradiation on the mixed solution after pH adjustment by using ultraviolet light of 200-300nm, and after the first irradiation, adding hydrogen peroxide in to the mixed solution and carrying out second irradiation by using ultraviolet light of 300-400nm at the same time to finally obtain water without antibiotics. The process provided by the invention for degrading the antibiotics in waste water not only is high in degradation rate, high in degradation efficiency and good in degradation effect, but also is low in raw material cost and nontoxic in byproduct, and can effectively control the concentration of the antibiotics in water, and data show that the degradation rate of the degradation process provided by the invention to the antibiotics in the waste water reaches 92-98%.
Description
Technical field
The invention belongs to water-treatment technology field, be specifically related to one and utilize UV/H
2o
2antibiotic method in combined removal water.
Background technology
Antibiotic medicine in water body environment is more and more subject to people's attention, their main source and pharmaceutical wastewater through not exclusively process and in biological sludge residues of antibiotics discharge or be released into surface water, thus contaminate environment water body, in addition, muck runoff is also occur antibiotic main source in water body.In recent years, at home, detect all to some extent in Europe and the sewage of the U.S. and surface water, concentration reaches nanogram and often rises to microgram and often rise the residues of antibiotics in water surrounding, and in water body after enrichment concentration can increase hundred times.
Even if the microbiotic in water body also can impact ecotope and HUMAN HEALTH when low concentration: the resistance that can promote microorganism in environment on the one hand, the enable effective antibiotics dosage killing bacterium constantly increases, and along with the enrichment of food chain, this resistance finally can be transferred in the microbe of harmful to human; In drinking water source, the raising of antibiotic concentration will constitute a threat to the biological safety of tap water on the other hand, especially tap water Biological Pretreatment unit and sewage core biological processing unit.
At present, both at home and abroad in water, especially antibiotic removal is mainly or rely on conventional aerobic, anaerobism or anaerobism adds aerobic bioremediation in tap water, but due to the resistance that microbiotic has, biological treatment mode cannot be played a role, after process, drinking water standard can not be reached completely.
Summary of the invention
In order to solve the problems referred to above that prior art exists, the invention provides that a kind of degradation rate is fast, degradation efficiency is high and good degrading effect utilize UV/H
2o
2antibiotic method in combined removal water.
The technical solution adopted in the present invention is:
One utilizes UV/H
2o
2in combined removal water, antibiotic method, comprises the steps:
(1) mixed with pretreated waste water by persulphate: add persulphate to pretreated waste water, the mass ratio of described persulphate and pretreated waste water is 1:500-1:1200, carries out stirring 60-90min, obtains mixing solutions;
(2) pH is regulated: the pH value of step (1) described mixing solutions is adjusted to 6-8, the mixing solutions after adjusted pH;
(3) utilize UV-light first time to irradiate water body: temperature be 60-80 DEG C, under stirring velocity is the condition of 100-150r/min, utilize the mixing solutions 30-60min after 200-300nm ultraviolet irradiation step (2) described adjustment pH, obtain the mixing solutions after first time treatment with ultraviolet light;
(4) utilize UV-light second time to irradiate water body: temperature be 20-50 DEG C, under stirring velocity is the condition of 200-250r/min, mixing solutions after step (3) described first time treatment with ultraviolet light adds hydrogen peroxide, and utilize 300-400nm UV-irradiation 30-60min, obtain removing antibiotic water in water.
In step (1), in described pretreated waste water, antibiotic concentration is 20-200mg/L.
In step (1), in described pretreated waste water, microbiotic is the mixture of one or more in penicillin, amoxycilline Trihydrate bp, Ciprofloxacin, Ofloxacine USP 23, Roxithromycin, clarithromycin, Amikacin, amphotericin, Sulphadiazine Sodium, tetracyclines and chloromycetin.
In step (1), described persulphate is Sodium Persulfate and/or Potassium Persulphate.
In step (1), the speed of carrying out described stirring is 260-350r/min.
In step (2), carry out the adjustment of described pH under agitation, described stirring velocity is 150-200r/min.
In step (2), use H
+concentration is acid solution and/or the OH of 1-50mol/L
-concentration is the adjustment that the alkali lye of 1-50mol/L carries out described pH.
Described acid solution is the mixture of one or more in perchloric acid, chloric acid, chlorous acid, hypochlorous acid, and described alkali lye is sodium hydroxide solution and/or potassium hydroxide solution.
In step (2), described pH value is regulated to be 6.5-7.5.
In step (4), the concentration of described hydrogen peroxide is 3-30wt%, and the ratio of the volume of the mixing solutions after the interpolation volume of described hydrogen peroxide and described first time treatment with ultraviolet light is 1:100-1:1000.
Beneficial effect of the present invention is:
Of the present inventionly utilize UV/H
2o
2antibiotic method in combined removal water, by first adding persulphate in pretreated waste water obtains mixing solutions, recycling acid solution or the pH of alkali lye to mixing solutions regulate, 200nm-300nm UV-light is first utilized to carry out first time irradiation to the mixing solutions after adjustment pH afterwards, after completing first time UV-irradiation, in mixing solutions, add hydrogen peroxide and utilize the UV-light of 300-400nm to carry out second time simultaneously and irradiate, finally obtain removing antibiotic water in water, technique of the present invention is degraded to microbiotic in waste water, not only degradation rate is fast, degradation efficiency is high, good degrading effect, and raw materials cost is low, by product toxicological harmless, effectively can control antibiotic concentration in water, data show, degradation technique of the present invention to degradation rate antibiotic in waste water up to 92-98%.
