| 摘 要： | 本文以无机氨氮废水为进水,乙酸钠为有机碳源,研究颗粒污泥CANON反应器中不同C/N水质条件下,反应器内的脱氮性能和N_2O释放情况,为探索合适的C/N比在高效脱氮的同时实现N_2O释放减量化提供理论依据.结果表明,C/N在0～2. 0范围内,随C/N的提高,TN去除率和去除负荷基本呈现逐渐升高的趋势,C/N=0时TN在7h内去除量为56. 50mg·L~(-1),去除率达到49. 00%,C/N=2. 0时,TN在7h内去除量最高为71. 42 mg·L~(-1),TN去除率最高为59. 52%,但是其中CANON对于脱氮的贡献逐渐下降,反硝化作用对于系统脱氮的贡献逐渐上升.当C/N=2. 0时,ΔNO_3~--N/ΔTN=0. 086,CANON对于系统脱氮的贡献仅为51. 48%,反硝化对系统脱氮的贡献为48. 52%. C/N在0～2. 0范围内,N_2O释放量和释放比例随进水C/N增加而降低,C/N=0时,N_2O释放量和释放比例最高,分别为3. 60 mg和2. 13%; C/N=2. 0时N_2O释放量和释放比例最低且分别为1. 61 mg和0. 75%.
