Co-cultivation of microalgae and microbes for pollutant removal from sewage is considered as an effective wastewater treatment method. The aim of this study is to screen the optimal photoperiod, light intensity and microalgae co-cultivation method for simultaneously removing nutrients in biogas slurry and capturing CO₂ in biogas. The microalgae-fungi pellets are deemed to be a viable option because of their high specific growth rate and nutrient and CO removal efficiency under the photoperiod of 14 h light:10 h dark. The order of both the biogas slurry purification and biogas upgrading is ranked the same, that is - > -activated sludge > under different light intensities. For all cultivation methods, the moderate light intensity of 450 μmol m s is regarded as the best choice. This research revealed that the control of photoperiod and light intensity can promote the biological treatment process of biogas slurry purification and biogas upgrading using microalgal-based technology.
微藻与微生物共培养以去除污水中的污染物被认为是一种有效的废水处理方法。本研究旨在筛选最佳的光周期、光照强度和微藻共培养方法，以同时去除沼气发酵液中的养分和捕获沼气中的 CO₂。微藻-真菌颗粒由于在 14 小时光照：10 小时黑暗的光周期下具有较高的比生长速率和养分及 CO 去除效率，被认为是一种可行的选择。在不同的光照强度下，沼气发酵液净化和沼气升级的顺序相同，即 - > - 活性污泥 > 。对于所有的培养方法，450 μmol m s 的中等光照强度被认为是最佳选择。本研究表明，控制光周期和光照强度可以促进基于微藻的技术进行沼气发酵液净化和沼气升级的生物处理过程。
