摘要
采用兼氧—好氧联合工艺对高浓度难降解化工废水进行处理。论述了用该工艺处理化工废水时 ,温度、p H值、负荷、水力停留时间等因素对稳定性的影响。该工艺利用兼氧和好氧微生物对高浓度化工废水进行处理后 ,CODCr的去除率达 95%以上 ,氨氮的去除率达 70 %以上 ,对色度有很好的去除效果 ,并且具有剩余污泥少、耐冲击负荷、费用低等优点 ,是一种高效、低能耗的废水处理工艺。
Facultative—aerobic union process is applied to treat highly concentrated refractory chemical wastewater. The effects of temperature, pH value, load and retention time on stability when it is used treat chemical wastewater has been discussed in this paper. After having treated the chemical wastewater by facultative—aerobic microbe, the COD Cr removal rate is about 95% and NH 3-N removal rate is about 70%, with a satisfied effect on decolourization.And,it is of advantage for less residual sludge,stronger impact load endurance,and less cost.It is a wastewater treatment process with high efficiency and low energy consumption.
