Pretreatment of piggery digestate wastewater by ferric-carbon micro-electrolysis under alkalescence condition
Abstract Due to the low COD/TN ratio, piggery digestate wastewater is non-biodegradable and pathogenic; its advanced treatment is becoming a wide-spread environmental concern. In this study, the process of Fe-C micro-electrolysis was applied to pretreat piggery digestate wastewater. Fe-C micro-elect...

| 520 | |a Abstract Due to the low COD/TN ratio, piggery digestate wastewater is non-biodegradable and pathogenic; its advanced treatment is becoming a wide-spread environmental concern. In this study, the process of Fe-C micro-electrolysis was applied to pretreat piggery digestate wastewater. Fe-C micro-electrolysis was confirmed effectively to enhance biodegradability of the piggery digestate wastewater. Response surface methodology (RSM) was employed to study the interactions between factors and optimize operating parameters. The optimum conditions for Fe-C micro-electrolysis were found to be 150 g/L of dosages of Fe-C particles, 6 L/h of aeration rate and 9 h of hydraulic retention time at pH 7.6, respectively. Under these conditions, the obtained chemical oxygen demand (COD) removal efficiency was 52.62%, and the ratio of BOD/COD increased from 0.13 to 0.285, which showed improvement of biochemical property. Furthermore, SEM analysis indicated the surface configuration of Fe-C particles. More important, this process could effectively pretreat the piggery digestate wastewater and avoid the generation of secondary pollution. | ||

In this study, the process of Fe-C micro-electrolysis was applied to pretreat piggery digestate wastewater. Fe-C micro-electrolysis was confirmed effectively to enhance biodegradability of the piggery digestate wastewater. Response surface methodology (RSM) was employed to study the interactions between factors and optimize operating parameters. The optimum conditions for Fe-C micro-electrolysis were found to be 150 g/L of dosages of Fe-C particles, 6 L/h of aeration rate and 9 h of hydraulic retention time at pH 7.6, respectively. Under these conditions, the obtained chemical oxygen demand (COD) removal efficiency was 52.62%, and the ratio of BOD/COD increased from 0.13 to 0.285, which showed improvement of biochemical property. Furthermore, SEM analysis indicated the surface configuration of Fe-C particles.

In this study, the process of Fe-C micro-electrolysis was applied to pretreat piggery digestate wastewater. Fe-C micro-electrolysis was confirmed effectively to enhance biodegradability of the piggery digestate wastewater. Response surface methodology (RSM) was employed to study the interactions between factors and optimize operating parameters. The optimum conditions for Fe-C micro-electrolysis were found to be 150 g/L of dosages of Fe-C particles, 6 L/h of aeration rate and 9 h of hydraulic retention time at pH 7.6, respectively. Under these conditions, the obtained chemical oxygen demand (COD) removal efficiency was 52.62%, and the ratio of BOD/COD increased from 0.13 to 0.285, which showed improvement of biochemical property. Furthermore, SEM analysis indicated the surface configuration of Fe-C particles. More important, this process could effectively pretreat the piggery digestate wastewater and avoid the generation of secondary pollution.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Piggery Digestate Wastewater</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Ferric-carbon Micro-electrolysis</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Response Surface Methodology</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Alkalescence Condition</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Wan, Jinbao</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Huang, Xueping</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Wu, Rongwei</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Liang, Kun</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">The Korean journal of chemical engineering</subfield><subfield code="d">Seoul : Inst., 1984</subfield><subfield code="g">34(2017), 9 vom: 24.

Pretreatment of piggery digestate wastewater by ferric-carbon micro-electrolysis under alkalescence condition |
| abstract |
Abstract Due to the low COD/TN ratio, piggery digestate wastewater is non-biodegradable and pathogenic; its advanced treatment is becoming a wide-spread environmental concern. In this study, the process of Fe-C micro-electrolysis was applied to pretreat piggery digestate wastewater. Fe-C micro-electrolysis was confirmed effectively to enhance biodegradability of the piggery digestate wastewater. Response surface methodology (RSM) was employed to study the interactions between factors and optimize operating parameters. The optimum conditions for Fe-C micro-electrolysis were found to be 150 g/L of dosages of Fe-C particles, 6 L/h of aeration rate and 9 h of hydraulic retention time at pH 7.6, respectively. Under these conditions, the obtained chemical oxygen demand (COD) removal efficiency was 52.62%, and the ratio of BOD/COD increased from 0.13 to 0.285, which showed improvement of biochemical property. Furthermore, SEM analysis indicated the surface configuration of Fe-C particles. More important, this process could effectively pretreat the piggery digestate wastewater and avoid the generation of secondary pollution. © Korean Institute of Chemical Engineers, Seoul, Korea 2017 |
