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。
It is very important to study the growth of Spirulina platensis and the treat- ment efficiency of N, and discuss the feasibility of treating wastewater using it. The re- sults 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 second- ary 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.
