摘　　要：餐厨垃圾废液是餐厨垃圾处理中最重要且复杂的环节。餐厨垃圾废液包含大量油脂、淀粉类有机物,并具有高COD、SS、氨氮、富营养化潜势等特点。选取的EGSB串联A2O-AO工艺,具有操作简单,占地面积小,投入成本低,减少二次污染。EGSB反应器在常温下对餐厨垃圾废液的COD去除率在80%~90%,对SS的去除率在62%~75%。AAO-AO一体化设备对进水废液COD的去除率在89.75%~93.13之间,对进水废液NH3-N的去除率在92.51%~97.34%之间,对进水废液TN的去除率在91.42%~97.75%之间,对进水废液TP的去除率在87.50%~98.25%之间。最终出水满足《污水排入城镇下水道水质标准》(GB/T 31962-2015)。Kitchen waste water is the most important and complex part of food waste disposal. The kitchen waste water contains a large amount of fat, starch organic matter, and has the characteristics of high COD, SS, ammonia nitrogen and eutrophication potential. The selected EGSB tandem A2O-AO process has simple operation, small footprint, low input cost and reduced secondary pollution. The COD removal rate of kitchen waste water reached 80%~90% and 62%~75% of SS in EGSB reactor at room temperature. The removal rate of COD of influent waste water was between 89.75% and 93.13%, the removal rate of NH3-N of influent waste water was between 92.51% and 97.34%, the removal rate of influent waste water TN was between 91.42% and 97.75%, and the removal rate of influent waste water TP was between 87.50% and 98.25%. All of these indicators could meet “Wastewater Quality Standards for Discharge to Municipal Sewers” (GB/T 31962-2015).
