摘要: 以生活污水为培养液时，钝顶螺旋藻的对数期一般在第4～11天。以一沉池污水为培养基时，其氨氮的去除率达到39.3%，以二沉池污水为培养基时，其硝态氮的去除率达到53.6%，处理后的出水水质均已达到GB18918—2002生活污水排放标准的一级A类标准，可直接排放。因此，利用螺旋藻去除生活污水中的N，具有很好的应用前景。

Abstract: It is very important to study the growth of Spirulina platensis and the treatment efficiency of N, and discuss the feasibility of treating wastewater using it. The results indicated that the lg phase was 4 to 11 days . Using the pool water as the medium, the removal rate of ammonia nitrogen was 39.3% and while using effluent of the secondary settling tank as the medium, the removal rate of nitrate was 53.6%. The quality of the treated water have achieved sewage discharge GB18918—2002 class A standard, and it can be discharged directly. So, Spirulina platensis had perfect application prospect in N content wastewater treatment.
Key words: sewage wastewater; Spirulina platensis; removal rate
