改性钙型粉煤灰对印染废水的处理

Printing and dyeing wastewater treatment with Ca-modified fly ash

煤炭燃烧会排放出大量的燃烧废弃物——粉煤灰.无论是从能源还是环境保护角度看,都是应重视的问题.改性粉煤灰具有良好的吸附性.以钙型粉煤灰对不同印染废水处理后的CODcr进行了测定,证明改性钙型粉煤灰处理印染废水有很好的效果.

The burning of coal drains off a lot of waste materials.Both from the perspectives of energy sources and environment protection,we should pay attention for it.Absorption is the mainly property of fly coal ash.This article determined the CODcr of the dyeing wastewater treated by Ca-modified fly ash.The experiments prove the good effect of fly coal ash on wastewater treatment.
