| 摘 要： | 试验采用了投料A2/O脱氮除磷工艺在广州市某污水处理厂进行中试,考察了不同混合液回流比及污泥回流比对投料A2/O工艺脱氮除磷的影响。结果表明,混合液回流比对COD、TP和NH3-N影响较小,对TN的去除率影响较大,系统混合液回流比为200%时,系统处理效果最佳;污泥回流比对系统整体功能的影响较大,随污泥回流比的增大,各指标的去去除率随之增大,结合处理效果和能耗情况,污泥回流比为75%时系统效果最佳。

| Abstract: | This paper intends to investigate how the ratios of return mixed liquor and return sludge affect the removals of nitrogen and phosphorus in a municipal wastewater treatment plant with A2/O process.Thus an experiment was conducted on a pilot-plant-scale installation of a series of tanks with biofilm carriers added in the aeration tank.Result indicates the mixed-liquor return ratio value has less effect on removal of COD and TP than on that of ammonia nitrogen.In general,with the sludge return ratio increasin... |
