摘要

摘要: 针对分散养猪冲洗水间歇产生的特点,采用间歇式厌氧折流板反应器(ABR,装置B)对其进行处理,考察COD负荷、冲洗次数、进水时间和温度对处理性能的影响,并与连续运行ABR(装置A)进行对比。结果表明:与进水COD相比,装置B对进水量更敏感,且其能承受的COD负荷较装置A低,但在平均COD负荷分别为1.03、2.06、1.39和1.82 kg/(m³·d)时,对应的COD平均去除率分别为76.2%、77.3%、86.0%和85.4%;增加冲洗次数至每天2次,有利于提升装置B的处理能力;延长进水时间至2 h,对装置B的处理性能没有影响;低温严重影响ABR的性能,温度降至15 ℃以下时,装置B对COD的平均去除率由17 ℃时的75.8%降至60.0%。

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 ℃.
