碩士 / 淡江大學 / 水資源及環境工程學系碩士班 / 99 / The high concentration nitrogen wastewater supplies microalgae with enough nutrient and suitable environment when using the microalgae treated the wastewater. The microalgae is provided with the characteristics of reproduce rapidly and quick adaptation, which have high efficiency to treat high carbon and high nitrogen concentration of wastewater. The microalgae would be a new clean energy source in this energy crisis days.
In order to find the optimum parameters of Chlorella sp. to treated wastewater, the aim of this study is to treat the high concentration of nitrate-based wastewater and observe the growth characteristics of Chlorella sp. The results indicated that the efficiency of the treatment is limited. The concentration of the nitrate nitrogen was decreased form 38 mg/L to 28 mg/L during treated time of 72 h. The removal efficiency only has 27%. But that would get the best removal efficiency and growth characteristics when the glucose was added as the carbon source. Furthermore, the removal efficiency of the nitrate nitrogen will up to 80% when the reaction obtained enough phosphorous and the reaction time was within 20 h. At this condition, the study could gain the highest specific growth rate 1.93 day-1 during 16-20 hours. Therefore, the carbon source is the main impact factor for treating the high concentration nitrate-based wastewater.
