摘　　要：采用固定化核蛋白小球藻去除人工废水中不同形态的氮磷,以评估其在生态环境中的生物选择性和可利用性.研究结果表明,当废水中同时存在氨氮、亚硝酸盐氮和硝酸盐氮时,固定化微藻首先去除氨氮,然后依次是亚硝酸盐氮和硝酸盐氮,在为期5d的试验中其去除率分别为100%、79.2%±0.8%和61.2%±0.2%;当废水中同时存在正磷酸盐和六偏磷酸盐时,固定化核蛋白小球藻优先去除正磷酸盐,然后去除六偏磷酸盐,在为期4d的试验中,其去除率分别为71.4%±1.6%和80.3%±1.0%.因此,固定化核蛋白小球藻对不同形态氮和磷的去除具有一定的选择性.In order to evaluate their bio-selection and bioavailability in ecological environment, immobilized Chlorella pyrenoidosa were used for removal of different forms of nitrogen and phosphorus from artificial wastewater. The results indicated that if ammonium, nitrate and nitrite existed in artificial wastewater simultaneously, the ammonium was firstly removed by immobilized Chlorella pyrenoidosa and then followed by nitrate and nitrite, respectively. And their removal rates were 100%,79.2%±0.8% and 61.2%±0.2%, respectively, during 5 days experiments. If orthophosphate and hexametaphosphate exist in wastewater simultaneously, the immobilized Chlorella pyrenoidosa would firstly remove orthophosphate, and then remove and 73.1%, respectively. Therefore, the different forms of wastewater could be selectively removed by immobilized Chlorella nitrogen and phosphorus in pyrenoidosa.
