| 城市污水培养微藻，可在实现污水无害化处理的同时，回收生物质能源。从反应器宽度、混合方式、磁场3个方面优化了利用城市污水室外培养斜生栅藻（Scenedesmus obliquus）的培养条件。结果表明：当反应器宽度为25 cm时，斜生栅藻干重与油脂产量较高，当反应器宽度为35 cm时，斜生栅藻油脂单位面积产量较高，较宽的反应器宽度表明深圳天气有利于斜生栅藻的室外规模化培养；较优混合方式为循环泵混合，该方式下斜生栅藻油脂产量相比不加混合的空白对照组提高了78.1%；将磁场应用于微藻培养中，当磁作用面积为2S、磁场强度为40 mT时，斜生栅藻油脂产量相比于不加磁场的空白对照组进一步提高了36.7%。 |
| 英文摘要: |
| Using municipal wastewater to cultivate microalgae can achieve not only harmless treatment of wastewater but also recovery algal biofuel as energy source. The outdoor culture conditions of Scenedesmus obliquus were optimized from three aspects including width of the reactor, mixing method and magnetic field. The results showed that when the width of the reactor was 25 cm, the dry weight and the lipid yield of Scenedesmus obliquus was higher, when the width of the reactor was 35 cm, lipid yield per unit area of Scenedesmus obliquus was higher, indicating that the weather in Shenzhen was conducive to large-scale outdoor culture of Scenedesmus obliquus. When using circulating pump to mix, the lipid yield of Scenedesmus obliquus was 78.1% higher than the control group without mixing. When magnetic area was 2S and magnetic field intensity was 40 mT, the lipid yield of Scenedesmus obliquus increased by 36.7% compared with the control group without magnetic treatment. |
