摘要：The best choice for removing COD,NH3-N and TP in eutrophic sewage (250.80 mg/L COD,20.67 mg/L NH3-N and 6.51 mg/L TP) was found to be Ceratophyllum demersum L.with aeration,Lemna minor L.at pH 7 and Ceratophyllum demersum L.with multilayer graphene oxide.Different pH values had significant effect on the physiological index of Ceratophyllum demersum L.as well as on the weight,content of carotenoid,soluble protein and vitamin E of Lemna minor L.Aeration had significant effect on the content of chlorophyll a,chlorophyll b,soluble protein and vitamin E of Ceratophyllum demersum L.,but for Lemna minor L.,it had significant effect on the content of carotenoid,soluble protein and vitamin E.Ceratophyllum demersum L.with multilayer graphene oxide was not practically applicable from the perspective of economic costs and treatment effects and use of intermittent artificial aeration might be a better strategy.
