Description
Technical field
The present invention relates to technical field of sewage, sulfa antibiotics minimizing technology in specially a kind of sewerage.
Background technique
Agricultural production, effluent of municipal sewage plant and sanitary sewage are the main sources of antibiotic pollution.Agriculturally, often
Addition antibiotic promotes growth of animal and prevention livestock disease in animal feed, and antibiotic medicine or metabolite are through animal
Urine and excrement discharge, are directly entered ecological environment, or enter soil by fertilization mode, enter water through the effects of rain drop erosion
Environment.Antibiotic residue brings adverse effect to aquatic ecosystem, leads to the generation of a variety of drug tolerant bacterias, also makes aquatic dynamic
Object vital movement is affected, while constituting potential threat, therefore sewage system to human health by modes such as drinking-water, food chains
The removal of antibiotic has become urgent problem to be solved in system.The sulfa antibiotics being especially widely present in sewerage, compared with
Difficult to degrade and removal.
Traditional antibiotic minimizing technology, main active sludge organism facture, chloridising, advanced oxidation processes, absorption
Method, electrochemical treatment and membrane separation process etc..Currently, high-level oxidation technology (AOP) is in sewage disposal process using more wide
General, the method for most common of them is Ozone and Fenton method, but the major defect of Ozone is that equipment investment is big, energy consumption
It is high；Fenton method during processing, if pH control is improper, is easy to generate a large amount of hydroxide precipitatings, and its solubility is urged
Agent recycling is more difficult；Absorption rule can generate new waste.
Major part processing method at present, is all difficult efficiently quickly to remove sulfa antibiotics in sewerage environmentally friendlyly, is
This, the present invention proposes sulfa antibiotics minimizing technology in a kind of sewerage, anti-effectively to solve sulfamido in sewerage
The problem of raw element pollution, human health is ensured, with more important practical significance.
Summary of the invention
Present invention aim to address in sewerage sulfa antibiotics removal process, existing restoration methods operating technology
Complexity, economic cost are high, and the problem of cannot efficiently remove sulfa antibiotics in sewage, provide sulfanilamide (SN) in a kind of sewerage
Class antibiotic minimizing technology.
To solve the above problems, sulfa antibiotics minimizing technology in a kind of sewerage, it is characterised in that: live modified
Property charcoal investment treatment tank in sulfa antibiotics in Adsorption sewage；
The modified activated carbon the preparation method comprises the following steps: washing active carbon dry, with washed repeatedly after concentrated sulfuric acid magnesium oxide/absorbent charcoal to
Neutrality is simultaneously dried, and is added concentrated sulfuric acid solution and is condensed back modification, obtains modified activated carbon；
The partial size of the modified activated carbon is 3-5mm.
Step 1: the washing active carbon method: with deionized water detergent active charcoal 3 ~ 5 times repeatedly, and in deionized water
Soaking conditions transfer ultrasound 10min ~ 15min in ultrasonic device, outwell to be put into baking oven after moisture and dry at 50 DEG C ~ 60 DEG C
It is dry.
Step 2: the magnesium oxide/absorbent charcoal method: being added concentrated sulfuric acid solution in the active carbon to after drying, and stirring 10min ~
15min keeps its fully oxidized, and 20h ~ take out solid afterwards for 24 hours and wash it to neutrality repeatedly is placed into baking oven in 50 DEG C ~ 60
It is dried at DEG C.
Step 3: the reflux method of modifying: by after drying active carbon be added concentrated sulfuric acid solution, stirring 10min ~
15min makes sulfuric acid and active carbon come into full contact with to be condensed back 1.5h ~ 2.5h under the conditions of 80 DEG C ~ 90 DEG C, takes out it after solid
It is washed repeatedly to neutrality, places into baking oven and dried at 50 DEG C ~ 60 DEG C, step 4: obtain modified activated carbon.
The concentrated sulfuric acid solution is analytical pure sulfuric acid.
The present invention has the advantage that as follows:
(1) present invention makes it have higher antibiotic absorption and fixed effect using active carbon is modified processing, and
And the method that antibiotic removes in sewerage proposed by the present invention can effectively remove antibiotic from sewerage, solve
Other pollutant residue problems in traditional sewage antibiotic treatment, the method to reduce its biological effectiveness fundamentally solve
The problem of certainly sewage antibiotic removes.
(2) raw material of the present invention easily obtains, and technology of preparing is simple to operation, and the period needed for sewage treatment is short, convenient for a wide range of
Popularization and use.
Specific embodiment
The present invention will be further described below in conjunction with the embodiments.Sulfamido in a kind of sewerage provided by the invention
Antibiotic minimizing technology, specific steps are as follows:
Sulfa antibiotics minimizing technology in a kind of sewerage of embodiment 1, with deionized water detergent active charcoal 3 times repeatedly,
