摘要
将由粉煤灰-土壤过滤后的沤麻废水收集,定期测定收集到的废水的COD值,研究粉煤灰-土壤对沤麻废水的处理效果,结果表明:3种规模的粉煤灰-土壤对沤麻废水的COD平均去除率分别达到84%,77.6%和72.3%,且随着土壤深度的增加COD的去除率有所增加,试验取得了一定的效果。
We collect the ret flax waste water which was filtered by soil-fly ash,determine COD value of the collecting wastewater on a regular basis and research the soil treatment system's effect on the ret flax waste water. The results show that COD removal rate reached average of 84%,77.6% and 72.3% for different size of three types of soil-fly ash. With the depth of soil increasing COD removal rate increases.
