固定化芽孢杆菌治理富营养化水体

Treatment of Eutrophic Water by Immobilized Bacillus

利用支柱石生物矿化法处理富营养化水的成本比理化方法低得多,已被研究多年。生物矿化鸟粪石是一种环保利用生物工艺沉淀磷酸盐、镁和铵离子的方法,细菌释放的碱性磷酸酶和氨具有较高的碱度和过饱和度,促进了支柱岩的成核。固定化蜡样芽孢杆菌的应用将为同时去除磷酸、镁、铵离子以及连续的支柱回收提供一种简单的环保、经济的方法,为富营养水的处理提供参考。所以固定化蜡样芽孢杆菌诱导的生物矿化鸟粪石在富营养水体的治理中有更明显的优势。

The cost of treating eutrophic water using pillar stone biomineralization is much lower than physicochemical methods and has been studied for many years. Biomineralized guanite is an environmentally friendly method of precipitation of phosphate, magnesium and ammonium ions. The alkaline phosphatase and ammonia released by bacteria have high alkalinity and oversaturation, which promotes the nucleation of pillar rocks. The application of immobilized B. cereus will provide a simple environmentally friendly and economical method for the simultaneous removal of phosphate, magnesium, ammonium, as well as continuous pillar recovery, providing a reference for the treatment of eutrophic water.
