摘要
根据含氰废水生物脱氮装置的运行实践分析了生物脱氮反应中废水的氨化、硝化和反硝化特点、原理,对装置进行改造后,氨氮合格率为95％以上。
Based on the operation experience of containing-acrylonitrile wastewater biology denitrogen unit, characteristics and principle of wastewater amination, nitration and anti-nitration were discussed in biology de-nitrogen reactions. Eligible content of more than 95% were reached for ammonia and nitrogen in treated wastewater.
