摘要

A molecular biology method, Fluorescent in situ hybridization (FISH), was used to investigate the vertical distribution characteristics of ammonia-oxidizing bacteria (AOB) quantity and the relation with oxidation-reduction potential (ORP) in the Typha latifolia constructed wetlands (CW) under three different loadings in Summer from May to September. Results showed that the quantity of the AOB decreased in the Typha latifolia CW with the increase of vertical depth, except in the root area where obvious rising was observed, and it was 2-4 times the quantity of the control. Additionally, ORP in the rhizosphere was found to be higher than other areas, which showed that Typha latifolia CW was in an aerobic state in summer when using simulated non-point sewage in rural area of Lake Taihu in China and small town combined sewage.
