粉煤灰虽然是一种固体废弃物,但已广泛应用于污水处理。本实验以锅炉房燃煤产生的粉煤灰为原料进行对生活污水的处理实验,主要研究在不同填料层高度,粉煤灰在单次进水和循环进水的情况下对生活污水中COD的去除率的差异;以及对高浓度垃圾渗滤液进行处理的对比性实验。结果表明,污水中COD的去除率随粉煤灰填料层高度的增加而提高,并且对低浓度生活污水中的COD去除效果较好。

Fly ash is a solid waste, but it has been used in sewage treatment extensively. The experiment is a sanitary sewage processing by using the fly ash from boiler building. The main study is the difference of COD removing rate with infusing water single time and many times under different padding level altitude, and relative experiment that the treatment of high density garbage waste water also has been carried on. The result indicated that the removing rate of COD has been raised with the height of filler increased. And ther...
