吉林省敦化县自1973年开始,经多方协助研制出压力式曝气锰砂过滤除铁装置(下称除铁装置)。我县东屯村一井深为53米,出水量36t/h,水中含铁12mg/l,水质浑浊,铁锈味很大,有棕红色沉淀物,安装除铁装置后,水中铁含量降至0.3mg/l以下。十多年来运转正常、效果可靠,适合农村应用。 除铁装置采用锰砂为滤料,锰有加速铁的氧化作用,并对地下水pH值低、水温低、含铁高有较好的适应性,其净水流程为:①深井泵→②加压泵→③加气阀→④混合器→⑤过滤罐→⑥贮水池 Dunhua County, Jilin Province has been assisting in the development of pressure aeration manganese sand filtration iron removal equipment (hereinafter referred to as iron removal equipment) since 1973. The depth of a well in Dongtun Village in our county is 53 meters, the water output is 36t/h, the water contains iron 12mg/l, the water quality is turbid, the rust taste is very large, there is a brownish red precipitate, and the iron content in the water drops to 0.3 after the iron removal device is installed. Below mg/l. For more than a decade, it has been operating normally with reliable results and is suitable for rural applications. The iron removal device adopts manganese sand as the filter material, manganese has the effect of accelerating the oxidation of iron, and has good adaptability to the low groundwater pH, low water temperature and high iron content. The clean water flow is: 1 deep well pump→2 plus Pressure pump → 3 filling valve → 4 mixer → 5 filter tank → 6 storage tank
