The performance of eological floating bed (EFB) with novel carbon source (CS) and reed biochar substrate (RBS) derived from reed straw (RS) was evaluated for the advanced treatment of effluent from wastewater treatment plants (WWTPs). The average carbon releasing capacity of CS was 4.50 mg/g, and the P adsorption capacity of RBS was 0.39 mg/g. The additional CS and RBS increased the average removal efficiencies of total nitrogen (TN) and total phosphorus (TP) by 57.6% and 46.7%, respectively. Furthermore, the high-throughput sequencing results revealed significantly different microbial species richness and diversity due to the CS and RBS. Some genera related to nitrogen removal, such as Pseudomonas, Rhodobacter, Hydrogenophaga, Bradyrhizobium, Acinetobacter and Thiobacillus, were enriched in the EFB with CS and RBS. This study provided a suitable method for effectively treating low C/N wastewater such as WWTPs effluent using EFB strengthened by processed wetland plant.

强化生态浮床可对市政污水处理厂的废水进行深度处理。

评估了具有新型碳源（CS）和源自芦苇秸秆（RS）的芦苇生物炭底物（RBS）的生态浮床（EFB）的性能，用于废水处理厂（WWTP）的废水的深度处理。CS的平均碳释放能力为4.50mg / g，RBS的P吸附能力为0.39mg / g。额外的CS和RBS分别使总氮（TN）和总磷（TP）的平均去除效率分别提高了57.6％和46.7％。此外，高通量测序结果表明，由于CS和RBS，微生物物种的丰富度和多样性差异显着。与CS和RBS一起在EFB中富集了一些与脱氮有关的属，例如假单胞菌，红细菌，氢生细菌，缓生根瘤菌，不动杆菌和硫杆菌。
