摘要
对以亚硝态氮为电子受体的同步脱氮除磷技术的影响因素进行了研究,分别考察了亚硝态氮最大抑制浓度、碳氮比、碳磷比、pH值等因素对氮和磷去除效果的影响,结果表明,亚硝态氮的最大抑制浓度为150 mg/L,COD∶NO2-N∶P最佳质量比大致为100∶7.69∶2,最佳pH值为7.39±0.2,此时磷的去除率接近100%.
This paper investigates some influential factors of synchronization nitrogen and phosphorus removal biological method which uses nitrite as electron acceptor. These influential factors separately include the nitrite maximal inhibitory concentration, the carbon and nitrogen scale, the carbeon and phosphorus scale, pH value and so on. The results indicated that the nitrite maximal inhibitory concentration is 150 mg/L. The prime proportion of COD： NO2 - N： P is 100： 7.69 ： 2. The prime pH value is 7.39 ± 0.2. Under these condition, The phosphorus removal efficiency appoachs 100%.
