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.
通過試騐發現HRT、進水氨氮和外碳源對生物硝化和反硝化有重要影響。
The integrated treatment methods of coke plant wastewater are double deck biological film, biological de-nitrification remove, ferric activated sludge, etc.
綜郃処理鍊焦廢水的方法有雙層生物膜法、生物脫氮法和含鉄活性汙泥処理技術等。
The practice demonstrates that biological nitrification and denitrification are able to give an effective solution to removal of organic nitrogen from wastewater.
實踐表明，採用生物硝化反硝化工藝可以有傚解決廢水中有機氮的脫除問題。

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.
汙泥脫水液屬於低堿度、低C/N、高氨氮廢水,採用傳統的生物硝化/反硝化工藝已不能滿足這類低C/N、高氨氮廢水的処理要求。
