摘要：
A novel filter-type constructed wetland was constructed by combining plastic fillers and mineral fillers for secondary effluent treatment. Findings showed that TN, TP and COD removal in the constructed wetland with composite fillers (CFCW) was 3.9%, 8.0% and 3.5% higher than that of constructed wetland with ordinary gravel fillers (CW) in the stable phase, respectively. CFCW showed better pollutants removal when dealing with higher influent concentrations and hydraulic loading. The main functional bacteria in two systems were significantly different (p < 0.05). Composite fillers could change the dominant genera, enhance genera activity and increase genera quantity. Denitrification (e.g., Pseudorhodobacter, Zoogloea, Pseudarthrobacter), nitrification (e.g., Devosia, Nitrospira), heterotrophic nitrification-aerobic denitrification (e.g., Paracoccus) and partial denitrification (e.g., g__Simplicispira) in CFCW provided diverse nitrogen metabolism pathways, resulting in higher nitrogen removal. The novel filter-type constructed wetland is suitable for the advanced treatment of sewage treatment plant effluent with enhanced pollutants removal and exuberant microorganisms.
