Article Synopsis
- ESDeN packed-bed systems show promise for denitrification but face challenges like biofilm growth and gas trapping, affecting performance.
- Water flush (WF) techniques can enhance denitrification rates, but their effects were not thoroughly studied until now.
- Results indicate that strategically controlling WF can significantly improve denitrification rates, with high-frequency and high-intensity flushing showing the best performance by optimizing retention time and reducing biofilm thickness.
Article Synopsis
- The Stockholm Convention classifies polychlorinated dibenzo-p-dioxins/dibenzofurans (PCDD/Fs) and dioxin-like polychlorinated biphenyls (DL-PCBs) as unintentionally produced persistent organic pollutants, commonly referred to as dioxins, linked to coke production.
- Intensive research on dioxin emissions from the coking industry remains limited, prompting the use of isotope dilution HRGC/HRMS techniques to analyze flue gas dioxin concentrations during coal heating.
- The study found that total toxic equivalents of dioxins ranged from 3.9-30.0 pg x m(-3), with higher chlorinated PCDD/Fs being the primary congeners,

Based on the requirement of National Implementation Plan for the Stockholm Convention on Persistent Organic Pollutants (NIP), six industries including pulp and paper industry have been set as the priority key sectors to implement the best available technology and best environmental practice (BAT/BEP) within a specific time for UPOPs reduction. Non-wood pulping has always played important role in virgin pulp production in China, its elemental chlorinated bleaching process has been confirmed as main source of Dioxin emission for the sector. As the signature party of Stockholm Convention and long time existing country of non-wood pulping, identification of Dioxin emission situation is significant importance to China to committee the obligation of Stockholm Convention.
