Description
Technical field
The invention belongs to technical field of waste water processing, and specifically disclosing a kind of handle by soda acid reduces antibiotic waste water life
The method of object toxicity.
Background technique
Antibiotic be widely used in human and animal's communicable disease prevent, treat and as animal growth promote
Agent.With the continuous growth of global antibiotic usage amount, antibiotic is making tremendous contribution for the mankind and animal health development.
As antibiotic usage is increasing, while bringing the environmental problem got worse.In production antibiotic process
In, unemployed antibiotic can be dissolved in waste water, and waste water enters in soil and water body after being discharged.Antibiotic enters
After soil and water body, potential hazard can be caused to publilc health and water environment, such as aquatic toxicity, the drug resistance of pathogenic bacteria, interior point
Secrete interference activity and genetoxic.Antibiotic in waste water cannot be effectively treated, and can cause seriously to pollute to environment.
Summary of the invention
The method for reducing antibiotic waste water bio-toxicity is handled by soda acid the purpose of the present invention is to provide a kind of, with solution
The problem of being certainly easy pollution environment containing antibiotic in waste water.
In order to achieve the above object, base case of the invention are as follows: a kind of handled by soda acid reduces antibiotic waste water life
The method of object toxicity, comprising the following steps:
(1) waste water containing antibiotic is extracted, strong acid is added into waste water and stirs 2-3h；
(2) waste water in step (1) is added alkali and adjusts PH to 6-7；
(3) waste water after extraction containing antibiotic is concentrated to give containing anti-by waste water in step (2) by extraction
The isolate of raw element；
(4) highly basic is added into the isolate of step (3) and inactivation treatment is carried out to antibiotic.
The working principle and beneficial effect of this base case is:
(1) this method processing antibiotic waste water process used in material be easy to get, using acid to wastewater treatment after, it is extra
Acid can be neutralized with alkali, will not discharge extra acid or alkali, smaller to environmental hazard；The treatment process time is short, place
It manages high-efficient；
(2) this method is easy to operate, and treatment process is less using power-equipment, consumes energy low, cost is small.
Further, in the range of adjusting PH to less than 4 after addition strong acid in step (1), standing time 2-3h.Place 2h
Afterwards, the antibiotic in waste water decomposes at most, in this way can be reduced to the toxicity of waste water minimum.
Further, waste water is heated using heater in step (1) and step (4) treatment process.To energy after waste water heating
Accelerate the inactivation speed to antibiotic, shortens the processing time.
Further, the PH of waste water is 6.5 in step (2).Waste water is adjusted to close to neutrality, reduces and contains in water
Acid, drop reduces the pollution to environment after discharge.
Further, the strong acid in step (1) is one of the concentrated sulfuric acid, concentrated nitric acid and concentrated hydrochloric acid；In step (2) and (4)
Alkali is sodium hydroxide or potassium hydroxide.Using meeting heat release when the concentrated sulfuric acid or concentrated nitric acid, certain heat effect is played to waste water, this
Sample is conducive to the antibiotic inactivation in waste water.
