    Abstract
  • The sequencing batch anaerobic baffled reactor (ABR, device B) was studied for treating washing wastewater of scattered piggery for its feather of intermittent discharge. The effects of COD load, washing times, influent time and temperature on the treatment performance of device B were investigated and compared with continuous operation ABR (device A). The results showed that device B was more sensitive to influent water rather than influent COD. Compared with device A, device B could afford lower COD load, while the removal rate of COD was 76.2%, 77.3%, 86.0% and 85.4%, when the average COD load was 1.03, 2.06, 1.39 and 1.82 kg/(m3·d),respectively. The treatment capacity of SB-ABR was improved by increasing the washing times to twice a day, while it had no influence by prolonging the influent time to 2 h. The performance of ABR could be seriously influenced by low temperature. The removal of COD by SB-ABR decreased from 75.8% to 60.0%, when the temperature fell from 17 ℃ to 15 ℃.
