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

Osorno致力于污水处理，是世界上最古老的成套污水处理系统之一BioCompact®的所有者。Osorno使用的废水处理设计以前没有应用于序批式反应器（SBR）工艺。本课题的目的是利用pH-ORP-T组合传感器研究活性污泥法污水处理系统的化学和生物过程动力学。通过采用Osornounder SBR处理技术制造的智能组合pH/ORP/T传感器，Osorno将有机会通过共同发表同行评审的研究论文来扩大其区域客户群和在加拿大的业务。该项目的范围是对现有SBR处理工艺进行实验室规模的基线比较，通过实施混合，曝气，和固定膜工艺的修改与先进的在线测量，以及相关的控制系统，使用组合的pH-ORP-T传感器由Osorno。我们将调查：研究了污水处理厂的运行条件和污水特性，研究了污水处理厂脱氮除磷的运行强化措施，研究了不同SBR工艺下的曝气程序，研究了维持最佳pH-ORP的投加量，研究了不同SBR工艺下的运行效果。5）研究实现营养物去除所需的自动化和控制。本研究项目的结果将提供一个非常-所需的SBR处理性能基线相对于目前只在加拿大研究型大学的实验室发现的过程增强。随着对SBR化学和生物处理动力学哪些具体方面存在缺陷的进一步了解，适当的工艺增强可能会导致SBR设计升级，这将使较小的人口中心能够以更具成本效益的方式改造和运行现有设施，同时满足其环境许可证的排放限制。

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.
