摘要
在等级FA深度处理焦化废水时,pH值和投灰量是影响废水处理效果的两个最重要因素,Ⅰ级FA的处理效果比Ⅱ级FA好一些。对经过生化处理的焦化废水,采用的pH越低,等级FA对COD和色度的深度去除率越高,而对NH3-N的深度去除率越低。等级FA深度处理焦化废水时,存在一个最佳投灰量,此时的废水处理效果最好。
In class Fly Ash(FA)advancedly treating coke - making waste water, pH and dosage are the two most important factors influencing waste water treatment. First class FA has better treatment effect than second class FA. About biologically treated coke - making waste water, the lower the used pH, the higher the removal efficiency of COD and colourity, the lower the removal efficiency of NH3 - N. There is a best dosage in class FA advancedly treating coke - making waste water. The waste water treatment effect is best while using the dosage.
