Various anthropogenic activities worsen climate conditions and cause water scarcity. As result, many studies have been conducted using microalgae to address these problems. Chlorella vulgaris is known to thrive in different type of environmental condition, making it beneficial for utilization. The objectives of this research were to combine the use of domestic wastewater (DWW) while at the same time inject CO₂ in order to analyze C. vulgaris’ ability to perform CO₂ uptake and wastewater treatment. Industrial CO₂ gas cylinder was used to supply CO₂ into the airlift photobioreactor (PBR) containing 40% and 60% DWW. C. vulgaris was inoculated into the biosystem and cultivated for 7 days. The results show that C. vulgaris can grow under high CO₂ supply conditions and used DWW as a nutrient source. The efficiency of pollutant absorption, such as ammonia, phosphate, MBAS ranges from 82.28% to 98.91%. However, its productivity is still low, and the organic matter (BOD and COD) treatment in DWW is not yet optimal.

普通小球藻的二氧化碳吸收和生活废水处理

各种人类活动使气候条件恶化并导致水资源短缺。因此，许多研究都使用微藻来解决这些问题。普通小球藻众所周知，它可以在不同类型的环境条件下茁壮成长，使其有利于利用。本研究的目的是结合使用生活废水 (DWW)，同时注入 CO ₂以分析普通念珠菌' 进行CO ₂吸收和废水处理的能力。使用工业CO ₂气瓶将CO ₂供应至含有40％和60％DWW的气升式光生物反应器(PBR)中。普通念珠菌接种到生物系统中并培养7天。结果表明普通念珠菌_{可以在高CO 2}供应条件下生长并使用DWW作为营养源。对氨、磷酸盐、MBAS等污染物的吸收效率在82.28%~98.91%之间。然而，其生产率仍然较低，并且 DWW 中的有机物（BOD 和 COD）处理尚未达到最佳状态。
