The aim of this work was to study the ability of using Hydrocabonoclastic native microbial and Spongiochloris sp microalgae in airlift bioreactors couples in order to restore hydrocarbons wastewater and develop the capacity of natural systems to reduce greenhouse effect through maximal control of CO gas emission in atmosphere. The kinetic parameters of CO gas fixation level and conversion it into biological material by microalgae as the biodegradation process effect in hydrocarbon have been evaluated. The result present that maximum specific growth rate μ of Spongiochloris sp was (0.87±0.04day) and the biomass productivity P was attended (1.5±0.3gLday) with maximal CO biofixation rate RCO (2.9205gLday). At 30°C and pH (7.6-7.4) the bioreactor showed a good wastewater removal efficiency (99.18%) in total hydrocarbons with COD stabilized within (1.30g/L), this result obtained suggesting that, the bioreactor applied system represented a useful strategy for maximizing CO bio-mitigation.
这项工作的目的是研究在气升式生物反应器中使用碳氢化合物分解土著微生物和海绵状微藻的能力,以恢复碳氢化合物废水,并通过最大程度地控制大气中 CO 气体排放来开发自然系统减少温室效应的能力。评估了微藻作为碳氢化合物生物降解过程的影响,将 CO 气体固定水平和转化为生物物质的动力学参数。结果表明,海绵状微藻的最大比生长速率μ为(0.87±0.04 天),生物量生产力 P 为(1.5±0.3 gL 天),最大 CO 固定率 RCO 为(2.9205 gL 天)。在 30°C 和 pH(7.6-7.4)下,生物反应器对总碳氢化合物表现出良好的废水去除效率(99.18%),COD 稳定在(1.30g/L)以内,这一结果表明,所应用的生物反应器系统代表了一种最大限度减少 CO 的有用策略。
