During the treatment of penicillin wastewater, facultative and aerobic bacteria in intermittent aeration can effectively degrade the organic matter in the wastewater without physical and chemical pretreatment of SO 4 2- and DTAB. When the highest COD concentration of the influent is 12 000 mg/L, the load is 8 kgCOD/(m 3 ·d), and the maximum impact load is 13 kg COD/(m 3 ·d), COD removal rate can reach over 87%. The foam produced by DTAB in penicillin wastewater will not affect the normal operation of the SBR treatment plant. The foam can disappear in the aeration process, and eventually the DTAB can achieve more than 97% removal rate. Therefore, sequencing batch reactor is an ideal way to treat penicillin wastewater.
