沸石曝气生物滤池预处理微污染源水

Zeolite Biological Aerated Filter for Treatment of Micro-polluted Source Water

考察了沸石曝气生物滤池(ZBAF)处理微污染源水的效果及其影响因素,结果表明,在停留时间为15～60min、气水比为1∶1、水温为17～26℃的条件下,处理CODMn为6.1～10.8mg/L、NH+4-N为2.3～5.2mg/L的微污染源水时,对CODMn、NH+4-N、UV254、浊度的平均去除率分别为31.2%、94.8%、9.3%和67.1%,且抗冲击负荷能力强。

Zeolite biological aerated filter (ZBAF) was used for treatment of micro-polluted source water, and its treatment effect and affecting factors were investigated. The result shows that under the conditions of HRT 15-60 min, air-water ratio 1∶1, and water temperature 17-26 ℃, as well as the influent COD Mn and NH + 4-N being 6.1-10.8 mg/L and 2.3-5.2 mg/L respectively, the removal rate of COD Mn , NH + 4-N, UV 254 , and turbidity is averaged at 31.2%, 94.8%, 9.3% and 67.1% respectively, with high resistance to shock loading.
