【摘要】 生物絮团技术是由微生物及微藻在特定生长阶段产生絮凝剂形成生物絮团,通过微生物和藻类代谢活动转化和同化氮磷等污染源,亦可是直接絮凝污染物并沉淀的物化过程。其具有绿色无污染的优势,且能实现资源的循环利用。在综述生物絮团技术在农村生活污水处理、畜牧业养殖废水处理和水产养殖中应用的基础上,提出应用生物絮团技术开发液体生物药肥,尽可能保留粪污中养分,实现肥药替代。更多还原

【Abstract】 Biofloc technology is a process in which microorganisms and microalgae produce flocculants at specific growth stages to form bioflocs,which transform and assimilate pollution sources such as nitrogen and phosphorus through metabolic activities of microorganisms and algae,or directly flocculate pollutants and precipitate them. It has the advantages of green and pollution-free,and can realize the recycling of resources. On the basis of summarizing the application of bioflocculant technology in rural domestic sewage treatment,animal husbandry wastewater treatment and aquaculture,this paper puts forward the application of bioflocculant technology to develop liquid biopharmaceutical fertilizer,so as to retain nutrients in manure as much as possible and realize the substitution of fertilizer and medicine.更多还原
