摘　　要：以不同碳源(PBS、PHB和陈米)条件下的反应器为研究对象,投加PBS和PHB后,系统对NH3-N的去除效果明显,去除率分别为PBS-14.29％～96.55％和PHB-57.89％～96.55％,而投加陈米后,出水NH3-N浓度比原水有所增加,均小于《城镇污水处理厂污染物排放标准》(GB 18918-2002)一级A标准.投加PBS和PHB的TN去除效果不佳,去除率分别为-35.49％～ 69.42％和-26.12％～64.64％,而投加陈米后对TN的去除效果显著,TN去除率为33.43％～93.37％.结果表明,采用陈米作为低C/N污水生物处理中反硝化的碳源是可行的.PBS,PHB and aged rice are applied as carbon source respectively to low C/ N wastewater.NH3-N removal is obvious for the denitrification system afteradding PBS and PHB,the removal rate of NH3-N is-14.29%-96.55% and-57.89% ~ 96.55% respectively.The effluent NH3-N concentration has increased than the rawwater after adding aged rice,is less than the first grade B of Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant(GB18918-2002).The removal effect of TN is not no good after adding PBS and PHB and the removal rate is-35.49% ~ 69.42% and-26.12% ~ 64.64% respectively;however,the removal rate of TB is remarkable for the addition of aged rice and the removal rate of TN can reach 33.43% ~ 93.37%.The results show that using aged rice as a denitrification carbon source in the low C/N wastewater biological treatment is feasible.
