项目摘要
Liquid waste is one of the main outcomes for many construction sites, such as direction drilling, tunneling, and hydro excavation. Reducing the current cost of liquid waste and improving the safety of these sites is important to mitigate greenhouse gases (GHGs) emissions and minimize transportation cost. MetaFLO is one of the leading providers of innovative, environmentally friendly chemistry and unique reagent delivery systems for the treatment and solidifications of liquid waste streams. MF002 and MF006 are proprietary reagent blends containing surface crosslinked sodium polyacrylate (super absorbent polymer), that immobilize the water in the liquid waste streams. Under the Anaerobic digestion of the waste, various complex chemical bonds may form acids and start damaging the superabsorbent polymer. Therefore, it is important to understand the mechanisms of Anaerobic Digestion (AD) on MetaFLO reagents in different liquid waste streams. The proposed project will be used to resolve and determine a new strategy to apply MetaFLO products into different liquid waste sites. This will be achieved using a lab-scale AD system to understand the potential degradation of MF002 and MF006 under different biological loading rates and the effect of environmental parameters (i.e. nutrient composition and concentration, pH, and the strength of ionic interactions) on the solid waste biodegradation.

液体废物是许多建筑工地的主要产物之一,例如定向钻孔、隧道和水力挖掘。降低目前的液体废物成本并提高这些场地的安全性对于减少温室气体排放和最大限度地降低运输成本至关重要。MetaFLO是创新、环保化学和独特试剂输送系统的领先供应商之一,用于处理和固化废液。MF 002和MF 006是含有表面交联聚丙烯酸钠(高吸水性聚合物)的专有试剂混合物,可将液体废物流中的水溶解。在废物的厌氧消化下,各种复杂的化学键可能形成酸并开始破坏高吸水性聚合物。因此,了解MetaFLO试剂在不同液体废物流中的厌氧消化(AD)机制是重要的。拟议项目将用于解决和确定将MetaFLO产品应用于不同液体废物场地的新策略。这将使用实验室规模的AD系统来实现,以了解MF 002和MF 006在不同生物负荷率下的潜在降解以及环境参数(即营养成分和浓度、pH值和离子相互作用强度)对固体废物生物降解的影响。拟议项目将用于解决和确定将MetaFLO产品应用于不同液体废物场地的新策略。这将使用实验室规模的AD系统来实现,以了解MF 002和MF 006在不同生物负荷率下的潜在降解以及环境参数(即营养成分和浓度、pH值和离子相互作用强度)对固体废物生物降解的影响。
