| 摘 要： | 为降低猪粪厌氧发酵废水－沼液对环境的污染，研究通过培养微藻的方法对其处理的效果。分别采用灭菌和不灭菌的方式对沼液进行预处理，接种微藻后测定培养过程中微藻的生长状况和沼液中主要水质指标COD、NH3-N、TN及TP的降低情况。结果表明，各项指标均有较为明显的下降，其中最重要的2个指标COD和NH3-N分别降低了85%和55%，由此说明，利用沼液培养微藻可以有效地清除废水污染物，同时可以获得具有商业价值的微藻细胞。

| Abstract: | In order to reduce the environmental pollutions of wastewater (biogas slurry) from anaerobic digested swine manure, the effects of microalgae culture on the treatment of biogas slurry were investigated. Two different ways as sterilization and non-sterilization were adopted to the pretreatment of biogas slurry. The algal growth status after inoculations and the decreases of main water quality indicators such as COD, NH3-N, TN and TP were determined. The results showed that there were significant drops in all indicators, of which the two most important ones of COD and NH3-N decreased by 85% and 55%, respectively. Therefore it is concluded that cultivation of microalgae using biogas slurry can effectively remove wastewater pollutants, and can also obtain commercially valuable microalgae cells. |
