【摘要】：生物碳是农业废弃生物质经裂解制备的富含有机碳和矿物质、结构复杂的碳材料。生物碳已被广泛应用于促进植物生长、增强环境生态修复,但是关于生物碳浸出液对水生生物的影响的研究还十分少。采用不同温度制备的生物碳的滤出液培养小球藻,研究不同滤出液对小球藻生长的影响。研究结果表明,随着生物碳裂解温度的升高,小球藻的生长逐渐变差:300℃生物碳滤出液培养小球藻的生物质总量最高,其次是500℃,最差的是700℃。另外,通过对滤出液成分的分析,发现影响小球藻的主要因素是滤出液的有机碳含量和p H。随着生物碳制备温度的升高,溶出的有机碳含量减少和p H升高,抑制了藻类的生长。
[Abstract]:Biological carbon is a kind of carbon material which is rich in organic carbon and minerals and has complex structure. Biological carbon has been widely used to promote plant growth and enhance environmental ecological remediation, but there are few studies on the effects of biocarbonate on aquatic organisms. Chlorella vulgaris was cultured in the filtrate of biological carbon prepared at different temperatures to study the effect of different filtrate on the growth of Chlorella vulgaris. The results showed that with the increase of biological carbon pyrolysis temperature, the growth of Chlorella microphylla gradually became worse. The biomass of Chlorella vulgaris cultured in biofiltration solution at 300 鈩，
