Simultaneous boron (B) removal and electricity generation from domestic wastewater using duckweed-based wastewater treatment reactors coupled with microbial fuel cell

摘要: Boron removal from water environment is a critical issue for scientific spotlight because its wastewater difficult and costly with conventional treatment method. Herein, an innovative, cost effective attractive method which depends on duckweed-based systems coupled microbial fuel cell reactor (DWWT-MFC) was investigated B-polluted domestic simultaneous electricity generation the first time in eco-technological study. Lemna gibba L. selected as model duckweed species, different reactors were also designed to identify mechanisms are dominant B DWWT-MFC matrix. achieved 71% experiment period, plant effect matrix recorded 37.7 ± 4.92% (F = 2.543, p < 0.05). However, supplementary aeration effects determined negligible. Average maximum voltage output found 1.47 V, power density 34.8 mW/m2 at current of 43.9 mA/m2 aeration. Moreover, 84%, 81% 76% COD, NH4+ PO43- efficiencies, respectively. grew well anode chamber average biomass yield 218 43 g/m2 total chlorophyll (a+b) concentration 30.2 mg g-1, indicates that anolyte not toxic growth. Consequently, it can be suggested environmental experts may use efficient treat produce bioelectricity.
