Characterizing BioCord fixed film technology for total nitrogen removal

氮是主要营养物质之一，如果过量污染湖泊、饮用水井、溪流和湿地。大多数营养物质来自人类活动，并通过市政和家庭污水系统。污水处理厂被要求在将氮等营养物质排放到水体之前将其去除。本研究采用BioCord生物膜技术去除生活污水中的氮。目前，BioCord技术已在几个城市污水处理应用中取得成功，包括泻湖和废水稳定塘。具体地说，它显示了在寒冷天气条件下，以较低的成本从流入的废水中减少氨和生物需氧量的能力。其半被动操作可实现高处理效率，同时将操作员监督、占地面积和运营/资本成本降至最低。然而，随着监管机构不断更新排放限制指南，以跟上日益增长的环境问题，预计减少总氮，而不仅仅是氨氮，将变得越来越可取。这项研究评估了以更高的强度和更低的能量投入管理氮素的新机会。毕晓普水务技术公司通过了解BioCord反应器内的总氮去除机制，并了解氧气输送对总氮减少的影响，通过提供能够满足未来处理目标的全面解决方案，有潜力保持在废水处理技术行业的竞争力。

Nitrogen is one of the primary nutrients if in excessive amount pollute lakes, drinking water wells, streams, and wetlands. Most nutrients come from human activities and through municipal and home sewage systems. Wastewater treatment plants are required to remove nutrients such as nitrogen before their discharge to water bodies. This research investigates using BioCord biofilm technology to remove nitrogen from domestic wastewater. Currently, the BioCord technology has been successful in several municipal wastewater applications, including lagoons and wastewater stabilization ponds. Specifically, it has shown an ability to reduce levels of ammonia and biological oxygen demand at a lower cost from incoming waste streams and during cold weather conditions. Its semi-passive operation allows for high treatment efficiencies with minimal operator oversight, footprint, and operational/capital costs. However, as regulatory bodies continue to update effluent limit guidelines to keep up with growing environmental concerns, it is anticipated that reductions of total nitrogen, not just ammonia will become increasingly desirable. This research evaluates a new opportunity to manage nitrogen at a higher intensity and lower energy input. By understanding the mechanisms of total nitrogen removal within the BioCord Reactor and discerning the effect of oxygen delivery on total nitrogen reductions, Bishop Water Technologies has the potential to remain competitive in the wastewater treatment technology industry by providing a comprehensive solution with an ability to meet future targets for treatment.
