摘要
粉煤灰处理废水是近几年粉煤灰综合利用研究的热点之一。本文就粉煤灰处理废水研究与应用的现状进行综述。粉煤灰处理废水的机理初步得到认识 ,其作用基本上以吸附为主 ,包括物理吸附和化学吸附 ,吸附规律符合Freundlich吸附等温式。粉煤灰对于染料废水、生产污水、焦化废水、酸性废水等污水均有较好的处理效果 ,但各种废水的质量分数均不能太高。
Among the application researches of flyash,flyash has been studied to be used in waste water treatment.The status of research and application of flyash in waste water treatment was summarized.The action mechanism of flyash was considered as absorption,including physical absorption and chemical absorption,and the absorption patterns tally with Feundlich Equation.Flyash could be satisfactorily used to treat many kinds of waste water including waste water from coking and dying industries and acidic waste water,but the concentration of waste water can not be too high.Now the urgent problems are how to increase the absorption capacity of flyash and how to treat the saturated flyash.
