摘要
利用钢渣过滤深度处理经生化处理过的焦化废水,钢渣能够吸附废水中的部分难生化降解的大分子有机物,降低废水的色度。考察流速和pH对吸附处理效果的影响,流速小时,吸附效果好,且pH偏碱性时吸附效果好。实验结果显示对颜色度(VIS380)和COD均有较为明显的去除能力。
A filter with steel slag was applied to the Tertiary treatment ofcoking wastewater. Refractory organics was removed by adsorption. When the velocity of flow was lower and pH =9, the removal efficiency could be improved. The experimental result demonstrateed that color and COD was removed apparently.
