摘要
本文研究了应用炉渣脱色印染废水,结果表明色度吸光值550nm可降低1500倍,S^(2-)降低3000倍,COD_(Cr)降低15倍,炉渣的粒径最好是 3～20mm。
This paper inuestigates the use of coal ash for decolouring the printing and dye-ing wastewater. The results show that the colour absorbance in 550 nm can be decreased by 1500 times, S2-by 3000 times, CODcr by 15 times. The best diamester of the coal ash is between 3-20mm.
