项目摘要

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.

如果过量污染湖泊，饮用水井，溪流和湿地，氮是主要营养物质之一。大多数营养物质来自人类活动以及市政和家庭污水系统。废水处理厂需要去除氮等养分，然后才能将其排放到水体之前。这项研究研究了使用生物犯罪生物膜技术从家用废水中去除氮。目前，在包括泻湖和废水稳定池在内的几种市政废水应用中，生物货币技术已经成功。具体而言，它显示出降低氨水和生物氧气需求水平的能力，其成本较低，从传入的废物流和寒冷的天气条件下。它的半通过操作允许使用最少的操作员监督，足迹和运营/资本成本来提高高度治疗效率。但是，随着监管机构继续更新废水限制指南，以跟上日益增长的环境问题，预计总氮的减少，不仅氨将变得越来越多。这项研究评估了一个新的机会，以更高的强度管理氮和较低的能量输入。通过了解生物反应器中总氮去除的机制，并辨别氧气递送对总氮减少的影响，主教水技术有可能通过提供综合解决方案，并具有实现未来治疗目标的能力，从而有可能在废水处理技术行业中保持竞争力。
