中文摘要 | 藻類處理廢水需要相當大的空間,因而使其在傳統廢水處理上的應用受到限制。 影響藻類對污染物去除效率的主要因素為反應器內的生物質量,故維持藻類成長效率最大並 減少藻類在出流水中損失為設計反應系統的重要因子。本研究利用照光的生物膜反應槽,以 經馴化的藻類 (Chlorella sp., Oscillatoria sp.) 處理合成廢水中的營養分 (氮、 磷 ) 和重金屬 (鈣、銅 )。此反應槽結構密實 (減少土地利用率 )、照光效率高、供藻類生長的 表面積大、每單位面積生物質量高、且處理效率佳。初步研究結果發現:此反應槽對含無機 營養分及部份重金屬物種的廢水具有良好的處理潛能。 |
英文摘要 | The application of traditional processes in which algae are used to treat wastewater is often limited due to the large space requirements. Since the removal of pollutants using algae depends mainly on the algal biomass within a reactor, it is important to design a system which maximizes the growth efficiency of algae, as well as reduce algal losses in the effluent. In this paper, an irradiance-driven biofilm reactor which uses acclimatized algae (Chlorella sp., Oscillatoria sp.) to removal nutrients (N, P) and heavy metal (Cadmium, copper) from synthetic wastewater is reported. The reactor is compact (low land utilization), has high irradiation efficiency, large surface area for algal growth, high biomass per unit area and high treatment efficiency. From the preliminary results, the reactor shows high potential in treating wastewater containing inorganic nutrients and some species of heavy metals. |
