摘要:
针对辽河铁岭新区段地下水中铁锰氨氮同时偏高的现象，由于传统的锰砂滤料并未起到较好的去除效果，故对其过滤工艺进行整改，使用了一种改性锰砂滤料。比较了2种传统滤料与改性锰砂滤料的处理效果，并且确定了改性滤料运行的最佳参数。结果表明：该滤料具有稳定的处理效果，在除铁除锰等方面性能优于普通的锰砂滤料以及石英砂等等。KMnO4最优的浸渍浓度为5%，5% KMnO4改性锰砂滤料过滤处理含氨氮的高铁锰井水的最佳工艺参数为：流量为35 ml/min，pH值为7.2，反冲洗周期与时长分别为18 h与5 min。在熟料运行条件下最佳DO值为10 mg/L。研究了此改性滤料不同滤层深度中溶解氧与铁锰氨氮去除效果的关系：发现铁最先在滤层上部最先去除，锰较氨氮优先使用溶解氧。
Abstract:
Aiming at the phenomenon that the high level of iron, manganese, ammonia and nitrogen in the groundwater of Tieling New District of Liaohe River at the same time, the traditional manganese sand filter media didn't have a better removal effect, so the filtration process was rectify and a modified manganese sand filter media was used.The treatment effects of two kinds of traditional filter media and modified manganese sand filter media were compared, and the optimal parameters of modified filter material operation were determined.The results showed that the filter material had a stable treatment effect, and had better performance than common manganese sand filter and quartz sand in iron and manganese removal.The optimal impregnation concentration of KMnO4 was 5%, and the best process parameters was that the flow rate was 35mL/min, the pH value was 7.2, the backwash period and the time length were 18h and 5min respectively.The optimum DO value was 10mg/L under the operating condition of the clinker.The relationship between the removal of dissolved oxygen and the removal of iron and manganese and ammonia nitrogen in the different filter layer depth was studied.It was found that iron was first removed in the upper layer of filter layer, and the manganese was preferred to use dissolved oxygen than ammonia nitrogen.
