摘要
金属涂饰和采矿等工业生产中广泛使用氰化物,产生的大量含氰废水对人类以及动植物形成严重威胁。工业上通常采用化学法处理含氰废水。某些微生物也可以氰化物作为氮源和碳源,将其降解为氨和碳酸盐等低毒性化合物。从经济角度来看,生物法比化学法成本低且效率高。综述了生物法降解氰化物的机理和研究进展。
As cyanide compounds are extensively used in industries, such as metal finishing and mining industries, a large number of the resulting wastewater containing cyanide is a serious threat to the human beings, animals and plants. Generally it＇s used to deal with wastewater containing cyanide by chemical methods. Several microbial species can also use cyanide as nitrogen and carbon source converting it into ammonia and carbonate which are less toxic. From an economic standpoint, the biological method has lower cost and higher efficiency as compared with chemical methods for cyanide removal. The present review describes the mechanism and research progress of biological method for the degradation of cyanide compounds.
