钝顶螺旋藻处理氨氮废水的研究

螺旋藻是一种营养丰富的新型保健食品，利用含氮废水为培养基，研究螺旋藻以NH4－N的处理效率，着重探讨利用生活污水培养螺旋藻的可行性，及其对生活污水的处理效果。研究证明，在NH4－N浓度小于40.0mg/L时，其对NH4－N的去除率最大，可达93％左右。在体积百分比生活污水为80％时，添加NaHCO38mg/L，对NH4－N的去除率达91.8%。同时对螺旋藻化学组分及含铁、锌、锰、铜、硒进行分析，生活污水培养螺旋藻，其所含有机物和氮源，可供螺旋藻生长繁殖，使废水资源化，并减少环境污染；藻粉可作为饲料添加剂，是使废水变为蛋白源的有效途径。

Study on Treating NH4-N Wastewater by Spirulina platensis

Study on treatment of NH4-N wastewater by using spirulina platensis has been conducted. When the concentration of NH4-N in wastewater was 40.5mg/l in culture of Zarrouk after 7d, NH4-N could be removed 93%, and in domestic wastewater, it could be removed about 91.3% when the volume of wastewater was 80% in culture and adding 8 mg/L of NaHCO3. In order to evaluate the availability of the algae, the chemical components of Fe, Zn, Mn, Cu and Se in spirulina platensis should be analyzed simutaneously.
