生物膜法在水产养殖水体处理中的研究与应用进展

Biofilm Method in Aquaculture Water Treatment: Progress of Research and Utilization

生物膜法是一种采用人工干预的方式促进废水中污染物降解的好氧生物处理技术。生物膜法净水效率高、成本价格低、操作简便、无二次污染,广泛应用于废水的生物处理,但应用于水产养殖水体处理仍然十分有限。本文综述了生物膜法的概念、生物膜的形成、影响因素及作用机理及其在我国水产养殖水体处理中的应用,展望了生物膜法在节水减排型的池塘养殖模式中的应用前景。

Biofilm treatment as a kind of aerobic biological treatment technology can successfully promote the degradation of pollutants in wastewater via artificial intervention, and has been widely used in wastewater treatment because of its high water purification efficiency, low cost, simple operation and no secondary pollution. However, the applications of biofilm treatment in aquaculture water treatment still remains so limited. In the paper, biofilm concept, biofilm formation, influencing factors, and mechanisms of biofilm treatment are reviewed and its applications in aquaculture water treatment is highlighted to give a preliminary outlook on future water-saving and emission-reducing aquaculture model via biofilm treatment.
