Development of Operational Enhancements for Biological Nutrient Removal to an SBR Wastewater Treatment System Using pH-ORP-T sensor

奥索尔诺致力于污水处理，拥有世界上最古老的污水处理系统之一——BioCompact®。Osorno使用的废水处理设计以前从未应用于顺序间歇反应器（SBR）工艺。该项目的目标是在组合pH-ORP-T传感器的帮助下，研究活性污泥废水处理系统中的化学和生物过程动力学。通过采用Osorno生产的智能组合pH/ORP/T传感器和SBR处理技术，Osorno将有机会通过共同发表同行评议的研究论文，扩大其在加拿大的客户群。该项目的范围是对现有的SBR处理工艺进行基准比较，通过实施混合、曝气和固定膜工艺修改，以及先进的在线测量和相关的控制系统，使用Osorno制造的组合pH-ORP-T传感器，增强营养物去除。我们将调查：1)污水处理厂的运行条件和废水性质；2)除氮、除磷的操作增强；不同SBR工艺下的曝气规划4)工艺中维持最佳pH-ORP的化学投加；5)调查实现营养物去除所需的自动化和控制。该研究项目的研究结果将为目前仅在加拿大研究型大学的实验室中发现的工艺增强提供急需的SBR处理性能基线。随着对SBR化学和生物处理动力学的具体方面的不足的进一步了解，适当的工艺改进可能会导致SBR设计升级，这将允许较小的人口中心以更具成本效益的方式改造和运营现有设施，同时满足其环境许可的排放限制。

Osorno is dedicated to wastewater treatment and is an owner of one of the oldest packaged sewage treatmentsystems in the world called BioCompact®. The wastewater treatment design used by Osorno has not previouslybeen applied to a sequencing batch reactor (SBR) process. The goal of this project is to investigate thechemical and biological process kinetics in activated sludge wastewater treatment systems, with the help ofcombined pH-ORP-T sensors. By employing the Intelligent combined pH/ORP/T sensors made by Osornounder the SBR treatment technology, Osorno will have the opportunity to expand their client base regionallyand their presence across Canada by co-publishing a peer reviewed research paper.The scope of this project is to perform a bench-scale baseline comparison of the existing SBR treatmentprocesse with enhanced nutrient removal by implementing mixing, aeration, and fixed film processmodifications together with advanced on-line measurements, and associated control system, using thecombined pH-ORP-T sensors made by Osorno. We will investigate: 1) operating conditions and wastewatercharacter at HWWTF; 2) the operational enhancements for nitrogen, phosphorus removal; the aerationprogramming under the different SBR processes 4) the chemical dosing to maintain optimum pH-ORP in theprocess; 5) Investigate the automation and controls needed to achieve nutrient removal.Findings from this research project will provide a much-needed SBR treatment performance baseline withrespect to the process enhancements that are currently only found in the laboratories of research universities inCanada. With an improved understanding of what specific aspects of SBR chemical and biological treatmentkinetics are deficient, appropriate process enhancements may result in SBR design upgrades that will allowsmaller population centres to retrofit and operate their existing facilities in a more cost effective manner, whilesatisfying their environmental license effluent limits.
