Performance, process kinetics and functional microbial community of biocatalyzed electrolysis-assisted anaerobic baffled reactor treating carbohydrate-containing wastewater

The microbial electrolysis cell and dynamic model have been applied to improve methane production and achieve the optimal regulation of a thermophilic ABR system; the effective performance was due to a synergy effect of functional microbes.

Influence Factors Analysis of Chloronitrobenzene Degradation in Biocatalyzed Electrolysis Systems

Chlorinated nitroaromatie compounds, which are widely used for synthesis industry of chemicals, pharmacy and pesticide, are listed on the priority pollutants by EPA and Chinese MEP. In this study, we investigated biocatalyzed electrolysis systems (BESs) with a bio-cathode seeding with enriched inoculum for the degradation of a typical chlorinated nitroaromatie compound: para-Chloronitrobenzene (4-CNB). Batch test results showed that the 4-CNB (30mg/L) would be completely degraded within HRT of 30 hours with 0.5V power supplied and NaAc (1g/L) as sole carbon source. The optimum operation conditions of CNB degradation in BESs was 50mM Phosphate Buffered Saline (PBS) (pH=7) and the distance of electrode is 1cm. But the 20mM PBS and the distance of 3cm would be acceptable and economic.
