含氰废水生物脱氮技术的应用

Application of Biological Denitrification Technology in Cyanide Waste Treatment

根据含氰废水生物脱氮装置的运行情况分析了生物脱氮反应中的硝化和反硝化特点、原理 ,对制约脱氮反应的硝化和反硝化的条件进行改进 ,在相同进水量的情况下 ,改进前 ,氨 氮合格率为 2 7 5 % ,改进后 ,氨 氮合格率为 89 5 %。

Based on the operation practice of biological denitrification equipment for cyanide waste,the characteristics and principle of nitration and denitrification in biological denitrification were analyzed,and reactive conditions were improved.
