氧化石墨烯抑制填埋场土工布初期生物结垢
Inhibition of initial bio-clogging of graphene oxide coated geotextiles in landfills
为研究氧化石墨烯对初期填埋场土工布生物结垢的影响，采取2种不同方法改性土工布，测试了改性前后土工布的Zeta电位、接触角和抑菌性能以及模拟填埋场渗滤液的微生物群落结构，并以土工布EPS含量评估生物结垢.结果表明，改性前后土工布都具有疏水性，但表面电位存在一些差异；渗滤液微生物含有细菌Paraclostridium和古菌Methanoculleus；氧化石墨烯对渗滤液微生物表现出抑菌性，细胞死亡率比空白组更高；氧化石墨烯加入萘酚胶水进行改性明显抑制了土工布生物结垢，EPS量比空白组减少了49%.
Geotextile clogging is a common issue in landfill. Two modified methods were applied to landfill geotextiles with graphene oxide (GO) to inhibit the geotextile bio-clogging in the early stage. Different chemical and microbial properties were analysed, including zeta potential, contact angle, antimicrobial activity and microbial community. The amount of EPS was tested to evaluate the bio-clogging. The geotextile was hydrophobic after modification, but the surface charge changes in some extent. The leachate consisted of bacteria Paraclostridium and archaea Methanoculleus. GO exhibited antibacterial activity in leachate. Compared to the blank group, the geotextile coated with GO and Nafion inhibited geotextile bio-clogging, resulting in 49% decreasing of EPS.
