Anaerobic digestate animal effluent (ADAE) contains high N and P nutrients which need to be treated. In this study, an integrated process was proposed using a microalgae consortium of Chlorella and Scenedesmus. The system was designed for 71 m3/d (medium-sized) and 355 m3/d (large-sized) animals of ADAE. Process simulation estimated to produce 83–417 kg d-1 of microalgae biomass which can be used as further products. As much as 2 kg of animal feed and 36–180 L/d of bio-oil can be produced during the treatment of 1 m3/d of ADAE. The produced biogas can generate 247–1,217 MWh y-1 of electricity. Likewise, the process can reduce greenhouse gas emissions by 2 kg-CO2eq kg−1 of hot standard carcass weight (HSCW). This integrated system offers merits in treating ADAE as well as producing chemicals and energy with low environmental burdens.

微藻联盟在处理未稀释的厌氧沼渣动物污水中的利用和整合，以生产动物饲料、生物油和沼气


厌氧沼渣动物污水 （ADAE） 含有高 N 和 P 营养物质，需要处理。在这项研究中，提出了一种使用 Chlorella 和 Scenedesmus 的微藻财团的综合过程。该系统专为 71 m3/d（中型）和 355 m3/d（大型）的 ADAE 动物而设计。过程模拟估计可产生 83-417 kg d-1 的微藻生物质，可用作进一步的产品。在处理 1 m3/d 的 ADAE 期间，可产生多达 2 公斤的动物饲料和 36-180 L/d 的生物油。产生的沼气可以产生 247-1,217 MWh y-1 的电力。同样，该工艺可以减少 2 kg-CO2eq kg-1 热标准胴体重量 （HSCW） 的温室气体排放。这种集成系统在处理 ADAE 以及生产化学品和能源、环境负荷低方面具有优点。
