摘　　要：城市化的迅速发展产生了数量巨大的生活污水,其化学需氧量(COD)、氨氮、总磷、总氮等指标较高,难以完全去除,造成生活污水难以回用。研究四尾栅藻和蛋白核小球藻两种不同的藻类对模拟生活原水COD、氨氮、总磷和总氮的去除效果,探索两种藻类在投加量为100 mg/L和200 mg/L时,对模拟生活原水各项指标随时间的去除效果。研究中采用SEM分析微藻处理污水前后的形貌变化,采用FTIR分析两种微藻在水处理前后表面化学组成的变化。结果表明:蛋白核小球藻和四尾栅藻对COD的去除效果十分显著,分别为77.92%和80.43%,而蛋白核小球藻对氨氮(58.34%)和总磷(51.09%)的去除效果优于四尾栅藻对氨氮(43.66%)和总磷(41.52%)的去除效果。四尾栅藻对总氮的去除效果(78.33%)优于蛋白核小球藻(76.67%).研究结果将为藻类微生物在生活污水高效治理方面提供理论基础和技术积累。The fast development of urbanization emits huge amount of domestic wastewater,of which the high contents of chemical oxygen demand(COD),NH_(4)-N,total nitrogen and phosphorous lead to the difficulty in their complete removal and the recycling of the water.To solve this problem,the simulated domestic sewage treatment efficiency was investigated via scenedesmus quadricauda and chlorella pyrenoidosa in terms of COD,NH_(4)-N,total nitrogen(TN),and total phosphorous(TP).The influence of the dosage of the two microalgae(100 mg/L and 200 mg/L)on wastewater treatment and the relationship of the indexes COD,NH_(4)-N,TN,and TP with handling time were examined.The surface morphology and chemistry before and after water treatment were characterized through SEM and FTIR,respectively.Scenedesmus quadricauda and chlorella pyrenoidosa show significant removal efficiency towards COD,with removal rates of 77.92%and 80.43%,respectively.Chlorella pyrenoidosa shows better NH_(4)-N(58.34%)and TP(51.09%)removal efficiency than scenedesmus quadricauda for NH_(4)-N(43.66%)and TP(41.52%).Scenedesmus quadricauda shows better TN removal efficiency(78.33%)than chlorella pyrenoidosa(76.67%).The results might provide fundamental and technical support for the application of algal microorganism.
