一体化生物滤池处理城市污水试验研究

Testing and study of municipal wastewater treatment by integrative bio-filter

通过试验研究一体化生物滤池对城市生活污水的处理效果。考察了水里停留时间(HRT)、COD容积负荷、填料高度、曝气强度等的影响。结果表明,在流量为85L/h、容积负荷在1.0～1.5kgCOD/(m3·d)、曝气强度在0.4～0.6L/(m2·s)之间时滤池水中COD和SS的去除率约为85%～90%,氨氮的去除率为61.7%。

The experiment was carried out on the use of Intergrated Biological Filer for treatment of municipal wastewater,and study was made on the effect of hydraulic retention time(HRT)?the loading of COD?the height of filling?and aerated intensity on the performance.The results showed that when the amount of flows is 85 L/h,the loading of COD is 1.0 kg COD/(m3·d)～1.5 kg COD/(m3·d)and aerated intensity is 0.4～0.6 L/(m2·s),the biofliter can efficiently remove COD and SS etc..
