摘要

The potential of the use of a new microalga strain Chlorella vulgaris IPPAS C-2015 (Chlorophyta, Trebouxiophyceae) for poultry wastewater treatment has been studied. The artificial wastewater (AWW) from chicken litter that mimicked real poultry wastewater was prepared, and the efficiency of the bioremoval of the inorganic anion from it and destruction of the organic contaminant in it during the new strain of C. vulgaris semi-continuous cultivation was assessed. After three days of C. vulgaris culturing, the initial nitrate and or-thophosphate levels in AWW decreased by more than 90% and more than 48%, respectively, and organic compounds were degraded by 80% on average (judging by chemical oxygen consumption). During the cultivation of the microalgae in AWW, the bacteria associated with the C. vulgaris pre-culture gradually replaced the bacteria characteristic of the AWW. The microalga biomass grown in AWW contained a great amount of polyunsaturated long-chain fatty acids from the C_(18) family. The capacities of the new C. vulgaris strain of being used in the combined poultry wastewater treatment and utilization of the resulting biomass are discussed together with the potential advantages of the microalgae-based over conventional biological wastewater treatment technologies.
