| 中文摘要 |
| 以我国北方某水库水作为试验用原水,对比研究了采用biostyrene轻质滤料为填料的新型生物滤池和生物陶粒滤池对该原水进行生物预处理时的实际运行情况.结果表明,作为一种生物预处理工艺,轻质滤料滤池处理过程可以明显地改善原水水质.对于该试验原水而言,轻质滤料滤池对CODMn的去除在5%～20%之间,对NH4+-N的去除则达到80%～95%,出水浊度也得到一定程度地降低,说明该滤池用于饮用水水源生物预处理是可行的.试验结果还表明,在相同的运行条件下,轻质滤料滤池对原水中的污染物,特别是对有机污染物和浊度的去除效率低于陶粒滤池,反冲洗过程对其运行效果的负面影响也比陶粒滤池显著. |
| 英文摘要 |
| A new biological filter called biostyr using biostyrene as media to purify raw water was compared with the widely studied bio-ceramic filter. The raw water was taken from a reservoir located in Northern China. It was shown this new biological filter could obviously improve the raw water quality. As far as the raw water investigated in this study was concerned, the removal percentage of CODMn, NH4+-N in the filter was 5%～20%, 80%～95%, respectively, and turbidity of the raw water decreased correspondingly, which indicated the feasibility that this filter could be applied in the field of biological pretreatment of raw water. It was also shown that under the uniform operating conditions, the performance of this new filter on the removal of contaminants, especially organics and turbidity, was slightly inferior to the bio-ceramic filter and would be more remarkably affected adversely by backwashing than bio-ceramic filter. |
