specific Embodiment approach 1

[0014] Specific embodiment one: a kind of method of removing tetracycline in water with microbial flocculant of the present embodiment, it is to carry out according to the following steps:

[0015] 1. Add microbial flocculant and coagulant aid to tetracycline water to obtain a mixed solution; wherein, the volume ratio of microbial flocculant to tetracycline water is 3:100; the volume ratio of coagulant aid to tetracycline water is 9:10000;

[0016] 2. After adjusting the pH value of the mixed solution, put it into a shaker, shake it for 0.1-90 minutes, take it out and let it stand for 5 minutes, it is completed;

[0017] Among them, the preparation process of the microbial flocculant is as follows: mix the dry powder of the microbial flocculant MFX with distilled water according to the mass-volume ratio of 1g: 480-520mL, place it on a magnetic stirrer, and obtain a microbial concentration of 2.0g / L after stirring. flocculant;

[0018] The concentration of the tetracycline wat...

specific Embodiment approach 2

[0019] Specific embodiment two: the difference between this embodiment and specific embodiment one is that the coagulant aid described in step one is CaCl with a mass fraction of 10%. 2 solution. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0020] Embodiment 3: This embodiment is different from Embodiment 1 in that ultrapure water is used as a solvent in the tetracycline water preparation process. Others are the same as in the first embodiment.

Abstract

The invention discloses a method for removing tetracycline in water by using a microbial flocculant, which relates to a method for removing tetracycline in water by using a microbial flocculant. The invention aims to solve the problem of secondary pollution in the traditional treatment method. The method of the present invention is one, adding microbial flocculant and coagulant aid in tetracycline water, obtains mixed solution; Wherein, the volume ratio of microbial flocculant and tetracycline water is 3:100; The volume ratio of coagulant aid and tetracycline water is 9 : 10000; 2. After adjusting the pH value of the mixed solution, put it into a shaker, shake it, take it out and let it stand for 5 minutes, filter it, and measure the liquid phase. The removal rate of tetracycline by the method of the invention can reach 70-80%.

Description

technical field [0001] The invention relates to a method for removing tetracycline in water by using a microbial flocculant. Background technique [0002] In the late 1990s, as a new type of pollutant in the environment, antibiotics began to attract widespread attention from foreign scholars for their environmental pollution and harm. Drugs for humans or animals are the main source of antibiotics. After the drugs are ingested by humans or animals, only a small part is actually metabolized, and most of them are excreted in the form of parent compounds or metabolites through animal feces and urine and enter the breeding wastewater Or in the surrounding water environment medium. The impact of antibiotic pollution in the water environment on human health is mainly manifested in the following two points: Pollution of drinking water and potential harm such as triple effects and intestinal flora imbalance; pollution of soil and food, and ultimately indirect harm to humans. Among ...
