摘要
微生物处理含氰污水是国内外正在探索的新技术．研究表明，微生物对污水中氰化物、硫氰酸盐、多种金属离子有脱除能力，并将氰化物、硫氰酸盐分解为CO2，NH3和硫酸盐，达到无毒排放．结合作者探索性研究的初步成果，综合论述了可用于处理含氰污水的微生物种属及其生化作用，介绍了国外的工业实践现状，微生物处理金矿含氰污水具有广阔应用前景．
The biodegradation of cyanide water is a kind of new technology in the world. Bacteria1 degradation has been shown to be effective in reducing cyanide, thiocyanate and metallic ions in the waste water of gold mines, and in decomposing cyanide and thiocyanate to carbon dioxide (CO2), ammonia (NH3) and sulphate during biodegradation. The bacterial strains used in the degradation of cyanide water and biochemical reaction are described with the writer's research achievement and the foreign industrial application is also introducd in the article. The biodegradation of cyanide water has wide application in gold mines.
