摘要： The purpose of this study is to study the effect of algae removal of nitrogen and phosphorus from the liquid of chicken manure to improve nutritional value of algae. In this experiment, the biogas slurry was diluted into 15%, 30%, 45% and 60% concentration gradients. We studied the growth of algae in different concentrations of methane and the effect of nitrogen and phosphorus removal from them, analyzed the nutrients of algae from different concentrations of biogas slurry. The results showed that: (1) Algae grow best in 15% biogas slurry, and the removal rate of nitrogen and phosphorus was the highest, with the increase of biogas slurry concentration, the growth of algae was inhibited, and the removal rate of nitrogen and phosphorus was also reduced. (2) The nutrient content of microalgae in 4 concentrations of biogas slurry was basically the same, there was no significant difference between them, and the content of harmful heavy metals was lower than that of Chinese feed standard, so it is a safe feed resource. Thus microalgae can be used to remove the nitrogen and phosphorus from the low concentration biogas liquid, so it can be used to treat the cultured sewage and produce high quality algae feed.
