The method for degrading antibiotics by using microbial flora in the embodiment comprises the following steps:
step one, sewage containing antibiotics is injected into the pretreatment tank 1 through a water injection port, harmful substances in the sewage are adsorbed and neutralized by an activated carbon layer, then the sewage enters the lower layer of the pretreatment tank 1 through an activated carbon layer 2, and solid impurities are retained on the upper layer of a filtering device.
Step two, pumping the filtered sewage into a microbial degradation tank by using a water pump, and then sequentially staying in degradation chambers added with microbial floras for degrading different antibiotics;
in this example, the first degradation chamber is filled with microbial flora of bacillus and flavobacterium, and is used for degrading B-lactam ring antibiotics;
a microbial flora consisting of acinetobacter, bacillus subtilis and nocardiaceae bacteria is added into the second degradation chamber, and degradation is carried out on macrolide antibiotics;
the third degradation chamber is filled with pleurotus citrinopileatus, human ochrobactrum and microzyme to form a microbial flora; degrading tetracycline antibiotics;
the fourth degradation chamber is added with proteobacteria antibiotics to degrade the sulfanilamide antibiotics.
The sewage stays in different degradation chambers for 7-14 days respectively in sequence, during the stay period of the sewage, according to the habits of microbial flora degradation in the degradation chambers, the temperature of the sewage is adjusted by a heating plate so as to be suitable for the reaction of the microbial flora, and the sewage is aerated by an aeration pipe, in the embodiment, the sewage is stirred by a motor and a stirring rod at a speed of 200-300 r/min for 8-16h every day.
Because the degradation chambers are sequentially arranged from top to bottom, the transfer of the sewage among the degradation chambers can be realized by opening the electromagnetic valves among the degradation chambers by utilizing the gravity of the sewage.
In other embodiments of the invention, the degradation chambers may be increased or decreased for different types of antibiotics in different wastewater sources, and microbial populations matching the target antibiotics may be added.
Step three: and after the second step is completed, directly discharging the sewage with the pH value meeting the discharge standard according to the pH value measured by the sewage, and injecting the sewage with the pH value not meeting the discharge standard into the first degradation chamber again to repeat the second step until the sewage reaches the standard. The retention time of the degradation can be adjusted according to the specific condition of the sewage.
In addition, after the filtration in the first step is completed, the activated carbon layer and the impurities retained thereon may be taken out together and pulverized, and then the pulverized activated carbon layer may be mixed with the furnace dust and the fly ash.
The furnace dust is the fusion product after coal burning, contains the oxide of a large amount of silicon, magnesium, calcium, aluminium, iron, and the furnace dust has porous structure, can adsorb the pollutant in the impurity, and the impurity influences local environment bacterium's drug resistance if directly abandoning easy polluted environment, and harm is very big, can adsorb, react, neutralize the harmful substance in the impurity through the furnace dust.
