微绿球藻对环境变化适应性较强，若用沼液培养既能节约成本，又可以避免沼液所含N、P导致水体富营养化。论文主要研究在微藻培养过程中，高温灭菌、盐度、pH值以及沼液稀释倍数等因素对微藻生长及N、P去除率的影响。研究表明，高温灭菌使TN、TP降低，对微藻生长不利；较高的pH值对生长不利，而且盐度为5％0时，微藻呈现负增长趋势。使用原沼液直接培养，体积分数为20％时，微藻生长最优，此时N、P去除率分别为71．96％和72．40％。TP去除率最高的是100％的沼液培养。去除率为80．63％，TN去除率最高的是40~,6的沼液培养，去除率为82．74％。

Nannochloris oculata has good adaptability to the environment changes. If use biogas slurry to cultivate, it can be efficient and avoid the eutrophieation lead by N and P. This paper try to study,during the cultivating process of microalgae,how sterilization, salinity, pH value and dilution ratio influence the grow condition and removal-rate of N, P. We found that high temperature sterilization make TN, TP reduee, has disadvantage the microalgae growth. High pH value in growth disadvantage, and when salinity is 5 ‰, microalgae present negative growth trend. Through this experiment, we have discovered that when culturing with biogas slurry directly and adding 4 times of distilled water, the grow condition is superior. At this time, the removal-rate of TN and TP are 71.96% and 72.40% respectively. The highest removal-rate of rip is 80.63% when cultivating with 100% percent biogas slurry, the highest removal rate of TN is 82.74% when cultivating with 40% pereent of the biogas slurry.
