摘要

为了实现东北地区低温（5~6℃）高铁、锰、氨氮（TFe：9~15mg/L，Fe²⁺：6~12mg/L，NH₃-N：1.4~2.0mg/L，Mn²⁺：1.4~2.0mg/L）地下水的净化及解决同层净化中运行稳定性差、出水锰超标的问题，在水厂净化车间开展“两级曝气+两级过滤”工艺启动研究，采用差滤速和同滤速2种启动方式分别启动两级生物净化工艺.结果表明，2种启动方式分别在106，59d启动成功.同滤速启动可以有效的缩短两级生物净化的启动时间，铁、锰、氨氮去除负荷可达110.69，18.80，19.54g/（m²·h），沿程分析发现，铁在一级滤柱的60cm处即被去除至痕量；85.08%的氨氮在一级滤柱中去除，沿程各段去除均匀，14.92%的氨氮在二级滤柱中去除；锰的去除率和氧化活性去除区位受滤速及进水氨氮浓度影响较大，33.72%的锰在一级滤柱中去除，66.28%的锰在二级滤柱中去除，锰的去除仍然是滤池成熟的决定性因素.

Abstract：

Poor operational stability and effluent manganese (Mn) concentration exceeding limitation were found during the same layer of purification process with the low-temperature (5~6℃) groundwater containing high ammonia nitrogen(NH₃-N), iron (Fe) and Mn contents (TFe:9~15mg/L, Fe²⁺:6~12mg/L, NH₃-N:1.4~2.0mg/L, Mn²⁺:1.4~2.0mg/L). In order to achieve efficient purification, the start-up of "two-stage aeration combined with two-stage filtration" purification process was investigated in water plant purification workshop, and the two-stage bio-purification was started separately by using the differential filtration rate and the same filtration rate. Results showed that two startup methods were started successfully after 59 days and 106 days. The start-up with the same filter speed shortened the startup time effectively, and the efficiency of Fe、NH₃-N and Mn were 110.69g/(m²·h), 18.80g/(m²·h) and 19.54g/(m²·h) respectively. Fe was removed to trace level at 60cm of the primary filter column; NH₃-N was evenly removed by 85.08% in the primary filter column, with the remaining 14.92% removed from the secondary filter column; the efficiency and the oxidation-removal active sites of Mn were obviously affected by the filtration rate as well as the influent NH₃-N concentration. Mn was removed by 33.72% and 66.28% in the primary filtration columnand and the secondary filtration column, respctively. Mn removal remains a decisive factor in filter maturity.

Key words： high iron manganese and ammonia nitrogen start-up the same filtration rate the differential filtration rate
