摘　　要：为实现生物除铁除锰工艺在低温(3~5℃)下的快速恢复,本试验研究了不同流向过滤方式、改变进水铁锰浓度、添加无机碳3种恢复方式对因锰中毒及长时间停运造成失效的生物除锰滤柱的恢复效果.研究结果表明,3种恢复方式均能够有效缩短生物滤柱的恢复时间,其时间分别为40,54,35d,相比2#滤柱常规恢复方式,1#、3#滤柱恢复时间分别缩短了26%、35%;尽管采用改变进水铁锰浓度方式的恢复时间较长,但滤柱恢复后除锰性能更稳定;从恢复效果和经济合理性综合考量,最佳恢复方式建议为铁锰浓度由低升高并在滤速提升至2~3m/h时添加无机碳的方式.In order to achieve the rapid recovery of biological iron and manganese removal process in the low-temperature(3~5℃),three kinds of recovery methods,including different filtration methods of the upper and lower flow,changing the the influent iron concentration and adding inorganic carbon,were adopted to study the recovery effect on the damaged biological filter column.The results showed that three recovery methods could effectively shorten the recovery time of biological filter column and the recovery times were40,54and35d,Compared with the conventional recovery mode of2#filter column,the recovery times of1#and3#filter column were shortened by26%,35%.Although the recovery time was longer by the way to change the concentration of iron and manganese,but the manganese removal performance after the recovery of the filter column was more stable.From comprehensive consideration of the recovery effect and economic rationality,It was suggested that the best way to recover damaged filter column was iron and manganese concentration increased from low to high and adding inorganic carbon when the filtration rate to2~3m/h.
