- 摘要:
- 富营养化引起的蓝藻水华暴发已经成为我国突出的水环境问题，现有对打捞蓝藻的处理处置方法主要包括干化焚烧、填埋、堆肥和沼气发电等，但是这些方法成本较高、资源化利用率低、二次污染严重，不符合新时期环境保护理念。蓝藻含有蛋白质和多糖（蓝藻淀粉、纤维素）等有机质，营养成分丰富，具有很好的开发利用前景。对蓝藻进行资源化利用，不仅能够缓解蓝藻的处理处置压力，也能实现变废为宝、变害为利的多重效益。综述了近年来国内外利用蓝藻制备生物燃料、提取藻蓝蛋白和制备有机碳源的研究现状及应用中存在的问题，可为构建蓝藻资源化利用新途径提供参考，助力实现碳减排与碳中和目标。
- Abstract:
- The outbreak of cyanobacteria bloom caused by eutrophication has become a significant water environmental challenge in our country. Current disposal methods for salvaged cyanobacteria include dry incineration, landfill, composting, and biogas power generation. However, these methods are associated with high costs, low resource utilization rates, and serious secondary pollution. These approaches are increasingly incompatible with modern environmental protection principles. Cyanobacteria are rich in organic matter and nutrients, such as protein and polysaccharides (cyanobacteria starch, cellulose), offering significant potential for resourceful utilization. Exploiting these resources can not only alleviate the burden of cyanobacteria treatment but also transform waste into valuable products. This paper summarizes the current research progress on the safe disposal and resourceful utilization of cyanobacteria, focusing on applications such as biofuel production, phycocyanin extraction, and organic carbon source manufacturing. These approaches can provide innovative strategies for cyanobacteria management while contributing to carbon emission reduction and carbon neutrality goals.
