Embodiment 1
[0044] A process for treating tetracycline antibiotic wastewater, comprising a pretreatment step and an anaerobic / aerobic treatment step;
[0045] The pretreatment step uses iron-carbon micro-electrolytic ceramsite as a filler for electrolytic treatment; the particle size of the iron-carbon micro-electrolytic ceramsite is 5-7cm, and the particle density is 1200-1400kg / m 3 , bulk density 850kg / m 3 , the packing height is 100cm, the hydraulic retention time is 4h, and the gas-water volume ratio is 5:1;
[0046] The described anaerobic / aerobic treatment step is to carry out anaerobic treatment and aerobic treatment successively to the wastewater after the pretreatment step, and the anaerobic treatment uses fly ash ceramsite as filler, and the particle diameter of fly ash ceramsite is 15-20mm, particle density 850-950kg / m 3 , bulk density 400kg / m 3 , the height of the filler is 100cm; the aerobic treatment uses sludge ceramsite as the filler, the particle size is 5-10mm, and th...
