Effect of Different Influent Conditions on Biomass Production and Nutrient Removal by Aeration Microalgae Membrane Bioreactor (ICFB-MMBR) System for Mariculture Wastewater Treatment
The nutrient removal and biomass production of the internal circulating fluidized bed microalgae membrane bioreactor (ICFB-MMBR) was studied under different cultivation modes, influent TOC, influent pH, and influent N/P. <i>Platymonas helgolandica tsingtaoensis</i> was used as the biolog...

| description | The nutrient removal and biomass production of the internal circulating fluidized bed microalgae membrane bioreactor (ICFB-MMBR) was studied under different cultivation modes, influent TOC, influent pH, and influent N/P. <i>Platymonas helgolandica tsingtaoensis</i> was used as the biological source. The growth of <i>P. helgolandica tsingtaoensis</i> and the removal efficiency of pollutants in the mixotrophy culture mode were improved compared with other culture modes. With the increased influent TOC, the average growth rate of <i>P. helgolandica tsingtaoensis</i> increased, and ammonia nitrogen and total phosphorus removal rate were improved. The <i>P. helgolandica tsingtaoensis</i> growth rate and nutrient removal efficiencies at the influent pH of 8 were the best among the different influent pH values. As the influent N/P ratio increased from 5 to 20, the <i>P. helgolandica tsingtaoensis</i> growth rate and pollutant removal rate increased gradually. When the influent N/P ratio was higher than 20, the <i>P. helgolandica tsingtaoensis</i> growth rate and pollutant removal rate tended to be stable and did not significantly change with the increase of influent N/P ratio. At the proper influent conditions, the high <i>P. helgolandica tsingtaoensis</i> biomass and nutrient removal efficiency could be obtained in the microalgae membrane bioreactor, which could provide a theoretical basis for the application of the system for wastewater treatment. |
