“…However, the generation of leachates is a critical issue of this landfill. Leachate is commonly generated from precipitation, surface run-off, and infiltration of groundwater percolating through the landfill [1,2]. Landfill leachate contains large amounts of organic and inorganic compounds, nutrients, chemical pollutants and heavy metals such as Pb, Ni, Cd, Cr, etc.…”

Purpose A bioelectricity producing system was configured by connecting to a microbial electrolysis cell producing hydrogen, in which both systems were without mediator, to treatment the landfill leachate of the and generate bioelectricity and hydrogen. Methods The anode electrode was made with MWCNTs polyscale coating on graphite felt and the cathode electrode with activated carbon coating on carbon cloth. In the MFC-MEC coupled system, the electrodes were connected in series using copper wire. The system was set up in a fed-batch mode and the landfill synthetic leachate was injected into the anode MFC-MEC chamber as fuel. ResultsIn MFC, the highest voltage, current density and power density were 1114 mV, 44.2A/m 3 and 49.24 W/m 3 , respectively. The maximum of the coulombic efficiency system was 94.10%. The highest removed COD, NH 4 -N and P was 97.38%, 79.56% and 74.61%, respectively. In the MEC, the maximum of voltage input, current density and power density was 1106 mV, 43.88 A/m 3 and 48.54 W/m 3 , respectively. The maximum coulombic efficiency system was 125.54%. Also the highest removed COD, NH 4 -N and P was 97.46%, 78.81% and 76.25%, respectively. The highest biogas production rate and its yield were 39 mL/L.d, and 0.0118 L/g CODrem, respectively. Conclusion This study found that the MFC-MEC coupled system had promising potential for strong wastewaters treatment, such as the leachate of landfill; and the in-site use of generated electricity and the production of useful fuels such as biogas.

Here, heterogeneous ternary metal oxide CdO:TiO 2 :ZnO (coded as CTZ0, CTZ1, CTZ2, CTZ3, CTZ4) nanocomposites are synthesized by a sol-gel precipitation method for the advanced oxidation process (AOP) under visible light. The structure, texture, and surface morphology of heterogeneous nanocomposites are identified by X-ray diffraction, high-resolution transmission electron microscopy, and field emission scanning electron microscopy, respectively, while the optical property is investigated by UV-vis spectrophotometry. Furthermore, mixed phases such as anatase and rutile TiO 2 , cubic CdO and hexagonal ZnO, as well as a mixture of morphology, viz., nanorod, nanoflakes, cluster, and aggregation of particles are observed concurrently for sample CTZ3. The reflectance of heterogeneous CdO:TiO 2 :ZnO nanocomposites is recorded in the visible wavelength range from 400 to 800 nm and optical bandgap is varied from 1.91 to 2.20 eV for samples CTZ1-CTZ4. The effect of weight load 5 g L −1 of heterogeneous nanocomposites is evaluated for degradation of organic dyes at neutral pH and obtains the highest efficiency for sample CTZ3 as 99.6% and 99.4% in methyl orange and methylene blue, respectively. Both biological oxygen demand and chemical oxygen demand values are reduced followed by AOP increasing the number of pollutant molecules for absorption in the mixture.
