利用粉煤灰处理采油废水的研究

The Study in the Treatment of Waste Waterfrom Oil Production with Powder Coal Ash

利用电厂粉煤灰及灰场氧化塘对现河首站采油废水中的污染物进行吸附和生化处理试验。试验结果表明:粉煤灰具有类似活性炭的结构和比表面积,对废水中的石油类、COD、氨氮、挥发酚等污染物具有较强的吸附、沉降和过滤作用。

The experiment on adsorption and biochemical treatment of the pollutant of waste water from oil production by powder coal ash of power plant and oxidation pond of ash field have been conducted. The result of experiment shows that powder coal ash is similar with active carbon in terms of structure and surface to volume ratio, which have strong adsorption, settlement and filter property against petroleum, COD, ammonia nitrogen, volatile phenol.
