基于城市污水资源化的跑道池培养小球藻条件优化
Optimization of culture condition for biodiesel production by Chlorella pyrenoidosa grown in municipal wastewater in open raceway ponds
摘要
Abstract
Cultivating microalgae with municipal wastewater can achieve not only treatment of waste water,but also recovery algal biofuel as energy source. Considering the similarities in principle and structure between raceway pond and oxidation ditch,this study aimed at turning the oxidation ditch into raceway pond,coupling of wastewater treatment and microalgae cultivation. This study investigated the adaptability of C.pyrenoidosa to different temperatures and pHs,and discussed the feasibility of coupling wastewater treatment and microalgae cultivation using raceway pond system. The results showed that the C.pyrenoidosa mutant strain could bear with temperature between 20℃and 40℃,and pH at the range of 5.7—9.7. Coupling wastewater treatment and microalga cultivation using the raceway pond system was feasible. The highest dry weight of C.pyrenoidosa was 0.2867 g/L,and the highest lipid yield of was up to 0.0696g/L. The water quality of effluent could consistenly meet the national emission standards. With the expansion of cultivation scale,open-pond culture technology had a great application prospect.关键词
