  • 摘要: 研究了分别以葡萄糖和乙酸钠为碳源时多点交替进水阶式A2/O(CMICAO)工艺氮磷的去除效果,以及在不同进水C/N比时各进水量分配对脱氮除磷效果的影响。结果表明,在相同的进水COD浓度下,乙酸钠比葡萄糖更适合作为碳源,更能提高脱氮除磷效率。以葡萄糖为碳源时,COD为200mg/L、C/N比为5、缺氧池与厌氧池进水配比为1:2时,出水COD、TN、氨氮和TP浓度分别为28.5、10.8、2.1和0.5mg/L,均达到国家一级A排放标准。若采用葡萄糖作为碳源,投加量以使进水C/N比为5~7.5为宜,外加碳源时缺氧池与厌氧池进水分配比可统一采用1:1。
    Abstract: Effects of glucose and sodium acetate as carbon source on nitrogen and phosphorus removal efficiency were researched for CMICAO process. The influence of water distribution with different carbon/nitrogen (C/N) ratios on the system performances was investigated. Higher nitrogen and phosphorus removal efficiency was achieved when sodium acetate was as carbon source instead of glucose. When using glucose as carbon source and COD was 200 mg/L, C/N ratio was 5 and water distribution of anoxic tank and anaerobic tank was 1:2, effluent concentrations of COD, TN, NH4+-N and TP were 28.5, 10.8, 2.1 and 0.5 mg/L, respectively, meeting the Grade A Standard. When using glucose as carbon source, C/N ratio should be controlled between 5~7.5 and water distribution of anoxic tank and anaerobic tank can be kept at 1:1.
