biological nitrification

基本解释

It is found that HRT, influent ammonia nitrogen and external carbon source have significant effect on biological nitrification and denitrification.
通过试验发现HRT、进水氨氮和外碳源对生物硝化和反硝化有重要影响。
The integrated treatment methods of coke plant wastewater are double deck biological film, biological de-nitrification remove, ferric activated sludge, etc.
综合处理炼焦废水的方法有双层生物膜法、生物脱氮法和含铁活性污泥处理技术等。
The practice demonstrates that biological nitrification and denitrification are able to give an effective solution to removal of organic nitrogen from wastewater.
实践表明，采用生物硝化反硝化工艺可以有效解决废水中有机氮的脱除问题。

生物硝化
Sludge liquor, which is characterized by high concentration of ammonium、low alkalinity and low C/N ratio. The conventional biological nitrification-denitrification cannot to achieve the processing request for this kind of waste water.
污泥脱水液属于低碱度、低C/N、高氨氮废水,采用传统的生物硝化/反硝化工艺已不能满足这类低C/N、高氨氮废水的处理要求。
