Abstract

The development of industry and agriculture has led to increasingly serious eutrophication of water bodies, and the study of methods for the effective treatment of wastewater is of great significance. This study was conducted to investigate wastewater treatment using Chlorella pyrenoidosa, Bacillus licheniformis, and microalgal-bacterial consortia under various carbon sources (glucose, sodium acetate, and citrate). Subsequently, the nutrient removal rate of each treatment was evaluated. The results showed that citrate was the optimal carbon source for Bacillus licheniformis in single culture, and the optimal carbon source for Chlorella pyrenoidosa was glucose. Microalgal-bacterial consortia could be effectively applied in wastewater treatment, since co-cultivation of these microorganisms could promote mutual growth and nutrients removal from wastewaters. The microalgal-bacterial consortia with glucose as carbon source had the highest treatment efficiency, the removal rates of TN, TP and TOC reached. 86.05%, 93.71%, and 82.19%, respectively. The wastewater treatment effects reached the wastewater discharge standard one day earlier than the microalgae culture system alone. Due to the effectiveness demonstrated by the studied consortia, it could be concluded that carbon source would be important factors on effects of microalgal-bacterial consortia.
