Deep nitrogen removal is difficult due to inefficient organic carbon sources in tail water from sewage treatment facilities. Microbial fuel cell integrated with constructed wetlands (MFC-CWs) filled high density polyethylene (HDPE) as the biocarriers were for deep denitrification of water, and was compared MFC CW. The influences electrode gap hydraulic retention time (HRT) on well electricity generation performance investigated. It found that appropriate extension might enhance chemical oxygen demand (COD) removal, MFC-CW got highest at 25 cm. Extending HRT promoted denitrification, resulting an initial increase followed by a subsequent decrease power performance. maximum attained 1.95 mW/m2 2 d. microbial abundances upper cathode systems higher, growth metabolisms microorganisms enhanced MFC-CWs. Saccharimonadales SBR1031 dominant genera, which removal. results provide reference study synchronous HDPE bio-fillers.

The aim of this study was to evaluate the effect a solid slow-release carbon source (3-hydroxybutyrate-co-3-hydroxyvalerate, PHBV) on heterotrophic and sulfur autotrophic cooperative denitrification (HAD) aquaculture wastewater. Batch tests were carried out analyze different PHBV/S volume ratios in range 30–70% synthetic wastewater under short hydraulic retention time (HRT). performance HAD process showed that NO3−-N removal increased with an increase ratio. When ratio reached 70%, average concentration effluent 0.38 mg/L stable phase. variation pH alkalinity value residual above 7.03 57.63 at 50%. Based relationship between sulfate generation nitrate PHBV/S, analysis proportion (HD) autotraophic (SAD) enhanced 50%, competition for substrates occurred 70%.
