ABSTRACT
Photobioreactor is deemed to be one of limiting factors for the commercial application of wastewater treatment based on microalgae cultivation. In this study, a novel Flat-Plate Continuous Open Photobioreactor (FPCO-PBR) was developed to treat piggery biogas slurry. The operation parameters, microbial stability and nutrient recovery potential of FPCO-PBR were investigated. Results showed that the appropriate influent mode for FPCO-PBR was multi-point or spraying mode. The optimal hydraulic retention time and interval time for biomass harvesting of FPCO-PBR were both 2â¯d. Nitrogen and phosphorus recovery rate were 30â¯mgâ¯L-1â¯d-1 and 7â¯mgâ¯L-1â¯d-1 respectively under optimal operating parameters. Microbial diversity remained relatively stable in FPCO-PBR. Biomass production rate of FPCO-PBR was 0.47â¯gâ¯L-1â¯d-1 under optimal operating parameters. The revenue generated from biomass was estimated to be 15.06â¯$â¯kg-1, which means that treating one ton of wastewater can generate $â¯7.08 in revenue.
