ABR/DAT-IAT工艺处理食品废水

Application of ABR and DAT-IAT Technology in Treatment of Food Wastewater

采用折板厌氧反应器(ABR)/好氧间歇曝气系统(DAT-IAT)处理食品废水,处理规模为800 m3/d。实际运行结果表明,当ABR的HRT为24 h时,系统出水水质可达到《肉类加工工业水污染物排放标准》(GB 13457—1992)的一级标准。

The combined process of anaerobic baffled reactor （ABR） and demand aeration tank- intermittent aeration tank （DAT-IAT） to treat food wastewater with a capacity of 800 m^3/d. The actual operation results show that when the HRT of ABR is 24 h, the final effluent meets the first class criteria specified in Discharge Standard of Water Pollutants for Meat Packing Industry （ GB 13457 - 1992 ）.
