  • 摘要: 采用海藻酸钠凝胶包埋固定小球藻和活性污泥，对冲厕海水污水（模拟）中的氮磷污染物进行去除实验。结果表明，在藻菌比为2∶1，固定化藻菌对氮磷的去除率分别达到95.5%和92.2%。在N/P为10时，固定化藻菌对冲厕海水污水中氮磷的去除效果最好。25～30℃时固定化藻菌对氨氮和磷的去除率最好，温度过高时藻和细菌细胞的活性受到抑制。固定化藻菌体系处理冲厕海水污水的较佳pH范围在6.5～8.5之间。
    Abstract: Chlorella and activated sludge were immobilized by sodium alginate to remove nitrogen and phosphorus from seawater toilet-flushing sewage. The results indicated that when the ratio of algae to bacteria was 2∶1， the removal efficiencies of nitrogen and phosphorus by immobilized Chlorella-bacteria reached 95.5% and 92.2%， respectively. When nitrogen-to-phosphorus ratio was 10， the removal efficiencies of nitrogen and phosphorus were the highest. The removal efficiencies were better at 25℃ to 30℃.The activity of algae and bacteria is inhibited at highly temperature. The favorable pH of immobilized algae and bacteria for seawater toilet-flushing sewage is 6.5～8.5.
