摘要
以粉煤灰为吸附剂研究其对焦化废水的净化效果及机理。在处理焦化厂生化出口水、粉煤灰负荷量为１．５ｇ／１００ｍｌ时，废水中挥发酚、ＣＯＤＣｒ、色度、油、ＢＯＤ５、氨氮和氰化物去除百分率分别为１１．２４，４７．６７，６０．８４，４８．７５，５８．３５，２５．０９和３０．００，平均去除率为４８．８５％。
The cleaning effecient of coking waste water and the related machanism are studied on the fly ash used as adsorbent. For cleaning waste water after biochemical treatment of the coking plant and at 1.5g/100ml ash load, the percentage reductions of the volatile phenols, CODc r, colour degree, oils, BOD 5, ammonia nitrogen and cyanides were 11.24, 47.67, 60.84, 48.75, 58.35, 25.09 and 30.00 respectively. The average reduction was 48.85 %.
