Effects of loading rates and N/S ratios in the sulfide-dependent autotrophic denitrification (SDAD) and Anammox coupling system.

This study investigated the shock resistance and the stability of a novel sulfide-dependent autotrophic denitrification (SDAD) and anaerobic ammonium oxidation (Anammox) coupling process for simultaneous removal of sulfide and nitrogen-containing wastewater in a single reactor. Results show that the total nitrogen (TN) removal efficiency reached 86.7% at a nitrogen loading rate (NLR) of 1.

Enhancing degradation and biogas production during anaerobic digestion of food waste using alkali pretreatment.

Alkali pretreatment of anaerobic digestion (AD) was investigated as a strategy to degrade complex organic matter such as fats. AD of food waste (FW) with alkali pretreatment was conducted using batch assays and long-term experiments for 70 days in two reactors. The aim of this study was to compare the impact of alkali pretreatment on solubilization and biogas production and to evaluate the performance in reactors with that of the untreated FW.

Phytoremediation potential of Miscanthus sinensis for mercury-polluted sites and its impacts on soil microbial community.

Phytoremediation potential of Miscanthus sinensis and its impacts on soil microbial community and nutrients were evaluated by pot experiment at soil mercury concentration from 1.48 to 706 mg kg. The changes in biomass yield in dry mass, chlorophyll content, and SOD activity indicated Miscanthus sinensis was tolerant to higher levels of soil mercury exposure, and could grow even if at soil mercury up to 706 mg kg.

Short term performance and microbial community of a sulfide-based denitrification and Anammox coupling system at different N/S ratios.

A novel sulfide-based denitrification and Anammox process was established for simultaneous removal of nitrogen and sulfide in a UBF reactor. The effects of the N/S ratio on reactor performance were investigated under five N/S molar ratios (4.56, 2.

[Determination of three phenolic compounds in water samples by solid phase extraction with microemulsion liquid chromatography].

A method for the determination of phenol, bisphenol A (BPA), 2,4-dichlorophenol in water samples based on solid-phase extraction with microemulsion liquid chromatography (MELC) was established. The water sample was acidified, and then cleaned-up by a C18 solid phase extraction cartridge. The separation was carried out on an Inertsil C18 (150 mm x 4.
