In this review we explore the biotic transformations of nitrogenous compounds that occur
during denitrification, and the factors that influence denitrifier populations and enzyme …

Simultaneous nitrification and denitrification (SND) is a promising single-reactor biological
nitrogen-removal method. Activated sludge with and without iron scrap supplementation …

Abstract Nitrate‐reducing, Fe (II)‐oxidizing bacteria were suggested to couple with
enzymatic Fe (II) oxidation to nitrate reduction. Denitrification proceeds via intermediates …

A pair of Fe-C electrodes was installed in a traditional submerged membrane bioreactor
(MBR, Rc), and a novel asynchronous periodic reversal bio-electrocoagulation system (Re) …

Nitrogen pollution in source water bodies is an urgent problem faced both domestic and
foreign countries. By taking inorganic electron donors as a breakthrough and constructing a …

微生物脱氮是一种经济有效的治理水体氮污染的手段. 目前微生物脱氮过程主要有厌氧氨氧化,
硝化, 反硝化及同时硝化反硝化等. 铁是环境中普遍存在的金属元素, 也是微生物所需的重要微量 …

Industrial wastewater contained a large amount of refractory organics, and single treatment
processes had limitations. This study investigated the mechanism of refractory organics …

Removal of phosphorus from a municipal wastewater by simultaneous precipitation of iron-
hydroxy-phosphate (IHP) was investigated. The addition of Fe 3+ was performed to …

Biological removal of chromate [Cr (VI)] in the presence or absence of nitrate by granular
sludge biofilms was investigated in batch experiments and in a sequencing batch reactor …

This study aimed to investigate the ammonia removal by the consortium mainly comprising
of ammonia-oxidizing bacteria under different initial pH, temperatures and stress of heavy …
