Embodiment 1

[0038] Ordinary tap water is mixed with tetracycline to make the concentration reach 1mM, hereinafter referred to as polluted water.

[0039] Combined with the accompanying drawings in the description, add polluted water 1 and powdered activated carbon 2 into the premix tank 3, the mass ratio of powdered activated carbon to polluted water is 1:800, and in the premix tank, a mechanical stirring device 4 is used , with intermittent mechanical stirring for about 5-10 minutes every 8 hours for 36 hours. Then the premixed water and powdered activated carbon mixture 5 are passed through a 400-mesh screen 7 through a pipeline 6 with a valve, and the filtered water 8 enters a collecting tank 9 . The above treatments were all carried out at ambient temperature.

[0040] Ordinary tap water contains tetracycline up to 1mM, add powdered activated carbon according to 1 / 800 of the water quality, stir intermittently for 5-10 minutes every 8 hours, after 36 hours, the concentration of tetrac...

Embodiment 2

[0042] Ordinary tap water was mixed with tetracycline so that the concentration reached 1mM.

[0043] Processing method is with embodiment 1.

[0044] Ordinary tap water contains tetracycline up to 1mM, add powdered activated carbon according to 1 / 400 of the water mass (to investigate the treatment effect when the amount of powdered activated carbon is increased), stir intermittently for 5-10 minutes every 8 hours, continue for 36 hours, and filter through a sieve The removal rate of tetracycline concentration < 0.1μM in the water body is nearly 100%.

Embodiment 3

[0046] Ordinary tap water was mixed with tetracycline to make the concentration reach 1mM, and urea was added to make the concentration 126mg / L (to investigate the influence of common components in tetracycline antibiotics production wastewater on the treatment effect of powdered activated carbon).

[0047] Processing method is with embodiment 1.

[0048] Ordinary tap water contains tetracycline up to 1mM, and urea 126mg / L. Add powdered activated carbon according to 1 / 400 of the water quality, and stir intermittently for 5-10 minutes every 8 hours. After 36 hours, the tetracycline in the water after filtering through the screen The removal rate of element concentration <0.1μM is nearly 100%.

Abstract

The invention belongs to the field of pollution prevention and control and discloses a method for treating a water body containing tetracycline antibiotics by using powdered activated carbon. The method comprises the steps of adding powdered activated carbon and the water body polluted by tetracycline antibiotics into a container, performing treatment by using the method of intermittent churning for a proper time, and then removing powdered activated carbon from the water body. The method has the advantages of simple operation, low cost, less time consumption, wide application area, safety and friendliness to the environment, as well as adaptability to industrialized application.

Description

technical field [0001] The invention belongs to the field of pollution prevention and control, and relates to a method for treating water containing tetracycline antibiotics by using powdered activated carbon. Background technique [0002] Tetracycline antibiotics are broad-spectrum antibacterial substances isolated from the culture fluid of the actinomycetes Streptococcus aureus, etc. Has a good inhibitory effect. [0003] Because tetracyclines are highly effective and broad-spectrum, antibiotics are commonly used to kill pathogens at home and in medical institutions. In particular, there are many kinds of antibiotics used in medical institutions and they are used intensively, but the metabolism efficiency of such drugs in the human body is very low. The treatment efficiency of antibiotics is limited. Today's reliance on and misuse of antibiotics in home health care and medical settings exacerbates the leakage of these antibiotics into the environment. [0004] Tetracyc...
