悬浮填料在给水处理中的应用

Application of Suspended Wadding to Water-Supply Treatment

研究了采用投加悬浮填料生物接触法对地表原水进行预处理，在一定水温、汽水比、水力停留时间下，对进水氨氮的处理效果。结果表明，投加悬浮填料生物接触法对高氨氮原水中的氨氮和亚硝酸盐氮具有较好的处理效果，去除率分别达到79％～90％和45．0％～73．9％。

Here is a study on the effect of the treatment of influent ammonia nitrogen on the condition that there is certain retaining time for the water temperature, the ratio of water to air and the water power by adopting the biological touching method of adding suspended wadding for pretreatment of the surface source water. The results from the study indicate that the biological touching method of adding suspended wadding has a good treating effect on the ammonia nitrogen in the high ammonia- nitrogen -contained source water and nitrous acid salt and the removal rate can reach 79 % - 90 % and 45.0 % - 73.9 % respectively.
