摘要
黑龙江化工总厂针对化肥改扩建后的废水水质情况，采用悬浮污泥法Ａ／Ｏ生物脱氮工艺和生物膜法Ａ／Ｏ生物脱氮工艺进行废水处理试验，结果表明，生物膜法Ａ／Ｏ生物脱氮工艺对废水中的总氮具有较好的去除效果，在废水碳氮比偏低的情况下，总氮的去除率可达到８４％左右。
Based on the characteristics of wastewater from chemical fertilizer production facilities after reformation and extension in Heilongjiang Chemical Plant, a study on the removal of nitrogen contained in the wastewater using suspended activated sludge A/O process and biofilm A/O process has been carried out. The experimental results show that the total nitrogen removal efficiency using biofilm A/O process can come up to about 80% even under lower ratio of carbon to nitrigen, which is hegher than that using suspended activated sludge A/O process.
