“…3). A previous study has verified that an ORP larger than À200 mv causes incomplete denitrification and that intermediate substances such as nitrite can accumulate in the system (Lee et al, 2000;Saliling et al, 2007).…”

“…However, in a marine anoxic denitrification system, as the denitrifiers deplete nitrate and nitrite, sulfate as the next best terminal electron acceptor can be used to produce toxic sulfide with sufficient organic electron donors as the redox potential decreases (Lee et al, 2000;Zhu et al, 2015). Besides, high carbon to NO 3 À ratios, high levels of sulfide and salinity provide favorable conditions to support dissimilatory nitrate reduction to ammonium (DNRA) over denitrification (Giblin et al, 2013), and this phenomenon as a competition to the denitrification process was widely detected in anoxic BDPs denitrification systems, especially in marine environment conditions (Chu and Wang, 2013;Shen and Wang, 2011;Zhu et al, 2015).…”

“…In a marine denitrification reactor, carbon source, the only electron donor, is competed for among several substances which play the roles of electron acceptors, such as oxygen, nitrate and sulfate (Gutierrez-Wing et al, 2012). The priority is established mainly by the energy yields, and oxygen provides the most energetic efficiency then followed by nitrate and then sulfate (Lee et al, 2000). Therefore, to solve the two problems using an anoxic PBS denitrification reactor mentioned above, a potential solution might be to apply oxygen to cut off the route of electron transport through DNRA and SRB under aerobic/anoxic operation.…”

“…Реа-лізація традиційної технології нітри-деніт-рифікації при очищенні оборотної води УЗВ супроводжується рядом характерних проблем, причини та наслідки яких дета-льно описані у роботах [1][2][3]. Попри те, що включення до схеми очищення оборотної води споруд з денітрифікації забезпечило можливість підвищити частку повторно ви-користаної води до 90-95% [4], потреба у реагентах (метанолі) створює додаткові ри-зики для риб та зумовлює зростання витрат на очищення води [5]. Використання в яко-сті джерела Карбону надлишкової біоплі-вки нітрифікаторів суттєво знижує інтенси-вність денітрифікації та спричинює додат-кове забруднення води органічними сполу-ками -продуктами розкладу біоплівки [6].…”
