A complex treatment of agricultural waste including the following major steps: anaerobic fermentation of suitable waste, cogeneration of the obtained biogas and growth of microalgae consuming the CO(2) from biogas and flue gas was verified under field conditions in a pilot-scale photobioreactor. The growth kinetics of microalgae Chlorella sp. consuming mixture of air and carbon dioxide (2% (v/v) of CO(2)), or flue gas (8-10% (v/v) of CO(2)) was investigated. The results obtained in the pilot photobioreactor were compared with results previously measured in laboratory photobioreactors. The field tests were performed in a pilot-scale outdoor solar-bubbled photobioreactor located at a biogas station. The pilot-scale photobioreactor was in the shape of a flat and narrow vertical prism with a volume of 300 L. The microalgae growth rates were correlated with empirical formulas. Laboratory analyses of the produced microalgae confirmed that it meets the strict EU criteria for relevant contaminants level in foodstuffs. Utilization of flue gases from cogeneration therefore was not found to be detrimental to the quality of microalgal biomass, and may be used in these types of bioreactors.
在一个中试规模的光生物反应器中，在现场条件下验证了包括以下主要步骤的农业废物综合处理方法：适合废物的厌氧发酵、所获得沼气的热电联产以及消耗沼气和烟道气中 CO2 的微藻生长。研究了消耗空气和二氧化碳混合物（2%（v/v）CO2）或烟道气（8-10%（v/v）CO2）的微藻小球藻的生长动力学。在中试光生物反应器中获得的结果与以前在实验室光生物反应器中测量的结果进行了比较。现场测试在位于沼气站的户外太阳能鼓泡光生物反应器中进行。中试光生物反应器呈扁平窄垂直棱柱形，体积为 300 升。微藻生长速率与经验公式相关。对所产微藻的实验室分析证实，它符合食品中相关污染物水平的严格欧盟标准。因此，发现热电联产烟道气的利用不会对微藻生物质的质量造成损害，并且可以在这些类型的生物反应器中使用。
