Abstract

This study evaluates the removal of COD and nitrogen from poultry wastewater in photobioreactors. Cell growth, the effect of light intensity (3200, 9800, and 12000 lux) and air flow (1.6, 3.2, and 4.8 L min−1) as a source of CO2 in bold basal medium and wastewater with different concentrations of COD were evaluated. The growth kinetics were modeled by using the Gompertz model and logistic model for both culture media. COD removals of up to 95% were achieved, and poultry wastewater was found to be a viable growing medium for Chlorella vulgaris. Finally, the wastewater met Mexican standards, and biomass was obtained with products valued as lipids (3.2 g lipid/100 g biomass) and proteins (342.94 mg L−1). The culture was found to have a dilatory behavior, and the rheological models of Ostwald de Waele, Ostwald de Waele linealized and Herschel Bulkley were utilized, showing a laminar behavior.

在用微藻小球藻培养的光生物反应器中去除家禽加工厂废水中的碳和氮

摘要

本研究评估了光生物反应器中家禽废水中 COD 和氮的去除情况。细胞生长、光照强度(3200、9800 和 12000 勒克斯)和气流(1.6、3.2 和 4.8 L min -1)作为 CO 2来源的粗体基础培养基和具有不同 COD 浓度的废水的影响是评估。通过对两种培养基使用 Gompertz 模型和逻辑模型来模拟生长动力学。实现了高达 95% 的 COD 去除率,并且发现家禽废水是小球藻的可行生长培养基。最后,废水符合墨西哥标准,获得的生物质产品价值为脂质(3.2 g 脂质/100 g 生物质)和蛋白质(342.94 mg L -1)。发现该培养物具有延缓行为,并利用 Ostwald de Waele、Ostwald de Waele linealized 和 Herschel Bulkley 的流变模型,显示出层流行为。
