曝气生物滤池填料选择的试验研究

Experimental study on biological aerated filter media selection

针对浊度以及悬浮物浓度较高的原水,将柱状炭和陶粒两种填料应用在曝气生物滤池中作为深度净水工艺的预处理的方法并对处理效果进行了比较和分析。试验表明:陶粒对原水中的有机物、NH+4-N、浊度等指标有较好的去除效果,而柱状炭不甚理想。

according to the turbidity and suspended solids concentration of high water, the columnar carbon and ceramic fillers are used in biological aerated filter as a preprocessing method of depth of water purification process, and the treatment effect are compared and analyzed. Experiments show that the ceramic has better re-moval effect of organics, NH4＋ -N, turbidity and other indicators in raw water, and the columnar carbon is not ideal.
