Integrated brownfield subsurface remediation technology development

由于城市基础设施的中断，城市中心内许多被碳氢化合物污染的地下场地无法挖掘，因此，公司通过确保有足够的氧气(O2)、磷(P)，有时还有氮气来进行碳氢化合物降解，从而刺激现场碳氢化合物的降解。然而，这一相对简单的目标具有挑战性，因为当碳氢化合物被降解时，O2和P会迅速耗尽，修复工作陷入停滞。联合鸡舍有限公司(FCL)已经开发了一套技术来避免这种补救停滞：即替代P物种、低分子有机酸(LMOA)和真菌。然而，这些方法中的每一种都是单独开发的，而且还不是一致有效的。FCL已与萨斯喀彻温省应用科学技术研究所(SIAST)和萨斯喀彻温省大学(S大学)合作开发综合棕地地下修复技术。基于NSERC Engage项目，FCL已与萨斯喀彻温省大学和SIAST接洽，以满足他们的科学和技术需求。由西西里亚诺领导的S大学团队，已经获得了两项国家环境研究委员会的资助，研究土壤中的真菌和LMOA以及

Many hydrocarbon contaminated subsurface sites within urban centers can not be excavated because of disruption to the city's infrastructure and thus, companies stimulate degradation of hydrocarbons onsite by insuring that there is sufficient oxygen (O2), phosphorus (P), and occasionally nitrogen, for hydrocarbon degradation. However, this relatively simple goal is challenging because O2 and P are rapidly depleted when hydrocarbons are degraded and remediation 'stalls'. Federated Coop Limited (FCL) has developed a suite of technologies to avoid this remediation stall: namely, alternative P species, low molecular weight organic acids (LMOA) and fungi. However, each of these approaches was developed in isolation and is not yet consistently effective. FCL has partnered with the Saskatchewan Institute of Applied Science and Technology (SIAST) and the University of Saskatchewan (U of S) to develop an integrated brownfield subsurface remediation technology. Based on a NSERC Engage project, FCL has approached the University of Saskatchewan and SIAST to address their scientific and technical needs. The U of S team led by Siciliano, has had two NSERC grants investigating fungi and LMOA in soil as well as
