摘　　要：微藻在处理养猪场废水的同时可生产出可再生能源微藻生物质,由此实现养猪场废水的生物资源化修复。本研究利用2种不同微藻即小球藻和莱茵衣藻,在不同温度环境(15℃和25℃)条件下,对不同起始氨氮浓度(100 mg/L和250 mg/L)的养猪场废水进行处理,分别测定微藻对养猪场废水中COD去除能力和微藻生物质累积能力。结果表明,小球藻和莱茵衣藻混合微藻在较高的养猪场废水起始氨氮浓度和较适宜温度条件(25℃)下具有较强的废水处理能力和生物质累积能力。Using the microalgae to treat piggery wastewater can produce renewable microalgae biomass,so as to realize the bioremediation of piggery wastewater.In this study,two different microalgae(Chlorella vulgaris and Chlamydomonas reinhardtii)were mixed to treat the piggery wastewater,with different initial ammonia nitrogen concentration(100 mg/L and 250 mg/L),at the different environment temperature(15℃and 25℃).The removal capacity of COD and the accumulation capacity of microalgae biomass in the piggery wastewater were measured respectively.The results showed that,under the condition of relatively higher initial ammonia nitrogen concentration and suitable temperature(25℃),the mixed microalgae(Chlorella vulgaris and Chlamydomonas reinhardtii)had strong wastewater treatment capacity and microalgae biomass accumulation capacity.
