摘要: Abstract It investigated the nitrogen removal performance and abundances of functional genes in rhizosphere non-rhizosphere when vertical flow constructed wetland (VFCW) was used to treat brackish eutrophic water. The results demonstrated that both total (TN) ammonia (NH4-N) efficiencies decreased with salinity increasing from 0.05% 1.0%. However, efficiency nitrate (NO3-N) remained more than 93%. found by quantitative real-time polymerase chain reaction (qPCR) amoA, nosZ, napA, nirK nirS were greater at salinities 0.05%, 0.5% As increased, abundance amoA reduced. indicated inhibited growth oxidizing bacteria (AOB) further hindered nitrification, which resulted deterioration TN performance. highest 1.0% salinity. denitrifying might adapt stress, guaranteed high NO3-N efficiency.
