微藻在水产养殖尾水治理中的应用研究

Study on the Application of Microalgae in Aquacultural Tail Water Management

摘要: 响应中共中央“绿色”“可循环”的号召，水产养殖尾水的处理一直以来都是备受关注的。水产养殖过程中由于投放饲料和抗生素导致水产尾水中含有较高含量的氮磷。微藻作为一种高耐受氮磷的生物，可以吸收氮磷转化为自身的蛋白质等。同时还可以进行碳的固定，是极为适合处理水产养殖尾水的生物。现在研究热点将微藻和细菌真菌共生，处理效果优于单一的藻种。同时，微藻作为高蛋白、多糖含量也很高的生物，不但可以作为养殖鱼虾贝类的饲料，还可以作为家禽的饲料。同时还有研究指出，微藻可以用来炼制生物柴油，如果普及的话，也可以成为一种新的干净清洁能源。总的来说，用微藻处理水产养殖的尾水，前景还是十分可观的。

Abstract: According to the CPC Central Committee’s call of “green” and “recyclable”, the treatment of aquacul-ture tail water has always been concerned. In the process of aquaculture, feed and antibiotics lead to higher nitrogen and phosphorus content in aquatic tail water. As a kind of organism with high tolerance to nitrogen and phosphorus, microalgae can absorb nitrogen and phosphorus into their own proteins. At the same time, it can also fix carbon, which is very suitable for the treatment of aquaculture tail water. Now the research focus is microalgae and bacteria fungi symbiosis, treatment effect is better than a single algae species. At the same time, as organisms with high protein and polysaccharide content, microalgae can not only be used as feed for aquaculture fish, shrimp and shellfish, but also as feed for poultry. It has also been suggested that microalgae could be used to make biodiesel and, if widespread, could be a new source of clean energy. In general, the prospect of using microalgae to treat aquacultural tail water is very promising.
