摘要:

针对酸化废水COD去除处理难度较高的特点，提出对酸化废水进行固化处理。通过固化实验研究；得出了固化处理配方。即水泥基固化配方为水泥35％(ω)，石灰10％（ω），粉煤灰20％(ω)；石灰基固化配方为石灰35％(ω)，水泥15％(ω)，粉煤灰10％(ω，下同)。实验结果表明，酸化废水经固化处理后，固化物稳定性好，固化产物浸出液中COD和重金属铬离子的含量都达到了国家标准要求。

Abstract:

The solidification treatment has been researched because of the difficulty in removing COD in the acidulated wastewater and the effective formulations are obtained. The formulation of solidification based on cement consists of 35% cement,10% lime and 20%
