摘要
采用生物陶粒柱(接种经筛选的工程菌)对水厂滤后水进行深度处理。结果表明,在水温为10～17℃、滤速为6 m/h、水力停留时间为40 min、气水比为1∶1的工况下,生物陶粒柱对滤后水中的CODMn、氨氮的去除率分别为30%和67.45%,优于水温为1～10℃、滤速为4 m/h、水力停留时间为30 min、气水比为1∶1工况下对两者的去除率(分别为10%和61.9%);两种工况下的出水浊度均在0.3～0.4 NTU。
The bioceramic column inoculated with effective microbe was used for advanced treatment of filtrated water in waterworks. The results indicate that under the conditions that water temperature is 10 to 17 ℃, filtration speed is 6 m/h, HRT is 40 min and air/water ratio is 1 ： 1, the removal rates of CODMn and NH3 - N are 30% and 67.45% respectively, better than 10% and 61.9% under the conditions of 1 to 10 ℃ water temperature, 4 m/h filtration speed, 30 min HRT and 1 ： 1 air/water ratio. The turbidity of the treated water is 0.3 to 0.4 NTU under the two running conditions.
