Conventional aerobic treatment of swine wastewater, which generally contains 4500–8200 mg L−1 of organic matter, is energy-consuming. The aim of this study was to assess the application of scaled-up microbial fuel cells (MFCs) with different capacities (i.e., 1.5 L, 12 L, and 100 L) for removing organic matter from swine wastewater. The MFCs were single-chambered, consisting of an anode of microbially reduced graphene oxide (rGO) and an air-cathode of platinum-coated carbon cloth. The MFCs were polarized via an external resistance of 3–10 Ω for 40 days for the 1.5 L-MFC and 120 days for the 12L- and 100 L-MFC. The MFCs were operated in continuous flow mode (hydraulic retention time: 3–5 days). The 100 L-MFC achieved an average chemical oxygen demand (COD) removal efficiency of 52%, which corresponded to a COD removal rate of 530 mg L−1 d−1. Moreover, the 100 L-MFC showed an average and maximum electricity generation of 0.6 and 2.2 Wh m−3, respectively. Our findings suggest that MFCs can effectively be used for swine wastewater treatment coupled with the simultaneous generation of electricity.

Organic Matter Removal

Lindane is a chlorinated pesticide known for its toxicity and persistence in the environment. Recently, it has been proposed that soil microbial fuel cell technology (SMFC) could be applied to enhance the removal of organic matter, phenol, and petroleum hydrocarbon in contaminated soil with simultaneous electricity output. Yet, there is no information on the application to remediation of soils polluted with pesticides. The purpose of this research was to evaluate the biodegradation of lindane with simultaneous electricity generation in an electrobiochemical slurry reactor (EBCR). The EBCR was inoculated with a sulfate reducing inoculum acclimated to lindane, it was further characterized, and batch operated for 30 day at room temperature. No external carbon source was supplemented in the experiment 1; the substrate was the soluble natural organic matter (NOM) of the soil. In the experiment 2 the EBCR was supplemented with a stock solution of sucrose: sodium acetate: lactate to give a final concentration of 2g COD/L in the reactor. Results from electrochemical impedance spectroscopy characterization in the EBCR (Experiment 1) showed that the equivalent circuit had a high anodic resistance R1=2064 Ω, cathodic resistance R3 = 192 Ω; and electrolyte/membrane resistance R2 = 7?, totaling a relatively high overall internal resistance Rint of 2263 Ω. During the batch operation, the EBCR showed a 30% lindane removal efficiency along with a maximum volumetric power of 165 mW m-3.This value compared favorably with results corresponding to sediments microbial fuel cells that are used to power weather monitoring systems. The organic matter removal was very high (72% as soluble COD, NOM) whereas the coulombic efficiency was low (5.4%). The latter, although, was higher than values reported for microbial fuel cells that degraded leachate-like effluents. In Experiment 2 of the EBCR both cell characteristics and performance significantly improved. The internal resistance as determined by polarization curve was 102 Ω when the two-electrode sets were connected in parallel. During the batch operation, the EBCR showed a 78% lindane removal and a maximum power volumetric of 634 mW m-3, the organic matter removal was 76% and coulombic efficiency was 15%. Finally, it can be concluded that our EBCR showed a high lindane removal capability and mixing of the slurry phase was associated to improvement of bioremediation and electricity performances of the device.
