氮形态对钝顶螺旋藻深度除氮性能的影响
|
Abstract:
摘要： 研究合成二级出水中不同氮形态(氨氮、亚硝氮、硝氮、尿素)对钝顶螺旋藻生长及除氮性能的影响。结果表明,钝顶螺旋藻在氮形态不同的模拟二级出水中均可生长并有效去除其中的氮。当二级出水中的氮源分别为氨氮(质量浓度为29.3 mg/L)、硝氮(28.3 mg/L)、亚硝氮(28.6 mg/L)、尿素(29.1 mg/L)时,处理5 d后,总氮的质量浓度分别降至3.5、6.8、4.6、4.0 mg/L。二级出水中75%以上的氮被微藻同化积累在藻体内,仅4%~10%以气态氮形式被去除。为二级出水中氮的深度处理提供了理论依据,为微藻培养提供新方案。
Abstract: The effects of different nitrogen species(ammonium, nitrite, nitrate, urea)in synthtic secondary effluent on Spirulina platensis growth and nitrogen removal performance was explored. The results showed that Spirulina platensis could grow and effectively remove nitrogen in secondary effluent. After 5 d treatment, concentration of total nitrogen(TN)were decreased to 3.5, 6.8, 4.6, and 4.0 mg/L, respectively, when the nitrogen species were ammonium(29.3 mg/L), nitrite(28.3 mg/L), nitrate(28.6 mg/L)and urea(29.1 mg/L). More than 75% of TN was assimilated in microalgae biomass, and only 4%~10% of TN was removed as gaseous nitrogen. This study provided a theoretical basis for further treatment of nitrogen in secondary effluent, and meanwhile, offered a new solution for microalgae cultivation
