Embodiment 1
[0024] A method for repairing tetracycline drug-contaminated wastewater, the steps are as follows:
[0025] (1) Pass the soil through a 20-mesh sieve after air-drying, and burn it at 600° C. for 15 minutes to obtain a restoration agent; the soil type is cinnamon, and the main clay minerals are kaolin and montmorillonite;
[0026] (2) Place the restorative agent prepared in step (1) in the contaminated wastewater with a concentration of 0.5 mg / L of tetracyclines (oxytetracycline, chlortetracycline, doxycycline and tetracycline exist simultaneously), and the repair is completed in 6 hours; The ratio of the quality of the restoration agent to the volume of the polluted wastewater is 1:1000g / mL.
Embodiment 2
[0028] A kind of repairing method to quinolones polluted waste water, the steps are as follows:
[0029] (1) Pass the soil through a 15-mesh sieve after air-drying, and burn it at 500° C. for 30 minutes to obtain a restoration agent; the soil type is cinnamon, and the main clay minerals are kaolin and montmorillonite;
[0030] (2) placing the restorative agent prepared in step (1) at a concentration of 0.8 mg / L quinolone antibiotics (ofloxacin, enrofloxacin, ciprofloxacin and norfloxacin exist simultaneously) polluted wastewater In 6h, the restoration is completed; the ratio of the mass of the restoration agent to the volume of the polluted wastewater is 1:1200g / mL.
Embodiment 3
[0032] A kind of repairing method to quinolones polluted waste water, the steps are as follows:
[0033] (1) Pass the soil through a 20-mesh sieve after air-drying, and burn it at 600° C. for 15 minutes to obtain a restoration agent; the soil type is fluvo-aquic soil, and the main clay minerals are kaolin and montmorillonite;
[0034] (2) placing the restorative agent prepared in step (1) at a concentration of 0.3 mg / L quinolones (ofloxacin, enrofloxacin, ciprofloxacin and norfloxacin exist simultaneously) polluted wastewater In the process, the restoration was completed in 5 hours; the ratio of the mass of the restoration agent to the volume of quinolone drug-contaminated wastewater was 1:900g / mL.
