The project proposes to evaluate a tertiary polishing treatment of a landfill leachate originating from an aerobic digestion process. The landfill leachate will serve as a liquid nutrient feedstock to culture microalgae, in particular Chlorella vulgaris and Dunaliella salina in a covered raceway pond type photo-bioreactor configuration. The evolved carbon dioxide from the aerobic digestion process will also serve as carbon feed to the photosynthetic microalgae. The evaluation of the process will be carried out over a period of 6 months with the help of one research assistant. An experimental raceway pond system will be constructed and investigated at Western in a configuration which simulates an on-site field environment. The effect of various parameters such as nutrient load, carbon dioxide sparging rate and loading, light intensity, temperature and pH etc. will be investigated. The aim of these studies will be to determine optimum operational parameters which maximize algal cell yield. The results will provide an integrated approach to produce clean water, capture carbon dioxide and provide value in the form of microalgae.

该项目建议对好氧消化过程中产生的垃圾渗滤液进行三次抛光处理。垃圾渗滤液将作为液体营养原料，在有盖的跑道池式光生物反应器配置中培养微藻，特别是普通小球藻和杜氏盐藻。好氧消化过程中释放出的二氧化碳也将作为光合作用微藻的碳饲料。该进程的评估将在一名研究助理的帮助下进行，为期6个月。将在WESTERN建造和研究一个模拟现场现场环境的实验跑道池塘系统。考察了营养盐负荷、二氧化碳释放率和负荷、光照强度、温度和pH等参数对培养效果的影响。这些研究的目的将是确定使藻细胞产量最大化的最佳操作参数。结果将提供一种综合的方法来生产清洁的水，捕获二氧化碳，并以微藻的形式提供价值。
