帕米尔绿球藻去除猪粪沼液废水中氮磷的效果研究

Effect of Chlorococcum pamirum on Removal of Nitrogen and Phosphorus from Piggery Biogas Slurry Wastewater

目前,微藻深度脱氮除磷是污水深度处理方面的热点研究。文章分别使用浓度为5%、10%、25%、50%的猪粪废水对帕米尔绿球藻进行培养,考察帕米尔绿球藻对不同浓度的猪粪废水中氨氮、总氮、总磷、磷酸盐的去除情况,结果表明去除效果最佳的是浓度为25%的猪粪废水。

At present,the deep removal of nitrogen and phosphorus from wastewater using microalgae is a hot topic in wastewater treatment.In this study,Chlorococcum pamirum was cultured in piggery biogas slurry wastewater with concentrations of 5%,10%,25% and 50%,respectively,and the removal of ammonia nitrogen,total nitrogen,total phosphorus and phosphate in pig manure wastewater with different concentrations was investigated.The results showed that the best removal effect was acquired in 25% concentration of pig manure wastewater.
