钛酸盐纳米材料和斜生四链藻协同处理农村生活污水的效应研究

摘要：

当前我国农村生活污水治理形势依然严峻.藻类和纳米材料结合可以有效地处理生活污水,探究纳米材料对生活污水中藻类的影响十分重要.基于钛酸盐纳米材料的调控,研究斜生四链藻处理生活污水的效应.结果表明,低质量浓度钛酸盐纳米材料添加到生活污水中后,斜生四链藻细胞经过6 d的适应期,表现出一定的生长促进作用,在10 d的培养过程中藻细胞增长了近97%.在质量浓度0.1 g/L的添加下,钛酸盐纳米材料对藻类生物量增长的影响最大,在0.2 g/L的添加质量浓度下,藻细胞生长受到抑制.

At present,the situation of rural domestic sewage treatment in China is still grim.The combination of algae and nano materials can effectively treat domestic sewage.Therefore,it is very important to understand the impact of nano materials on algae in domestic sewage.Based on the regulation of titanate nano materials,the effects of Tetrastreptococcus obliquus on domestic sewage treatment are studied.The results showed that low concentrations of titanate nano materials showed the growth promoting effect after a 6-day adaptation period,the algal cells increased by 97%after 10 d.Titanate nano materials had the greatest impact on the growth of algae biomass at the concentration of 0.1 g/L.The growth of algae cells was inhibited at the concentration of 0.2 g/L.
